The pedal feels fine, then goes long and soft mid-session. Pads get the blame, but more often it's the fluid. The factory fill in most street cars was never meant for lap after lap of hard stops, and it has usually been absorbing moisture for years.<\/p>\n\n      <p>This guide explains dry and wet boiling points and DOT ratings, then compares Motul RBF 600, 660 and 700 with the Brembo, Wilwood and EBC fluids we carry. Every boiling point comes from the fluid maker's own page or data sheet. We also cover bleed intervals and why fluid, pads and rotors work as a set.<\/p>\n\n      <div class=\"callout\">\n        <strong>Shop racing brake fluid at Track Ready Products:<\/strong> Motul RBF, Brembo, Wilwood and EBC track fluids in one place. <a href=\"https:\/\/www.trackreadyproducts.com\/brake-fluid-c-792_854\/\">Browse our track brake fluid selection<\/a>\n      <\/div>\n\n\n      <!-- Section 1 -->\n\n      <h2 id=\"why-fluid-fades\">Why Stock Brake Fluid Fades on Track<\/h2>\n\n      <p>On a road course, repeated stops from high speed push heat from the pads into the caliper and the fluid behind the pistons. If the fluid boils, it forms vapor bubbles. Liquid barely compresses, but vapor does, so the pedal travels further before the pads clamp. That's the long, soft pedal drivers call fade, and it can arrive with little warning.<\/p>\n\n      <p>Two numbers describe how much heat a fluid can take:<\/p>\n\n      <ul class=\"bf-list\">\n        <li><strong>Dry boiling point<\/strong> is the boiling point of fresh fluid straight from a sealed bottle.<\/li>\n        <li><strong>Wet boiling point<\/strong> is the boiling point after the fluid has absorbed a set amount of water. Motul measures its wet figure after adding 3% water, and its RBF 660 data sheet says that represents the fluid's condition after about one year of use.<\/li>\n      <\/ul>\n\n      <p>Glycol-based fluids (DOT 3, DOT 4 and DOT 5.1) absorb moisture, and Wilwood says \"over time the boiling point is gradually reduced.\" The dry figure is the best the fluid will ever be. The wet figure is closer to what fluid that's been in the car a while can handle.<\/p>\n\n      <div class=\"callout\">\n        <strong>A high dry boiling point doesn't last.<\/strong> Once a bottle is opened, the fluid starts absorbing moisture. That's why wet boiling point and bleed frequency matter as much as the headline number. Keep bottles tightly capped and use a fresh one for a pre-event flush.\n      <\/div>\n\n\n      <!-- Section 2 -->\n\n      <h2 id=\"dot-ratings\">DOT 3, DOT 4, DOT 5.1 and \"Racing DOT 4\"<\/h2>\n\n      <p>DOT ratings come from the U.S. standard FMVSS 116. They set <strong>minimums<\/strong>, not targets. According to the DOT tables Wilwood and Motul publish:<\/p>\n\n      <div class=\"table-wrap\" role=\"region\" aria-label=\"Minimum brake fluid boiling points by DOT rating (FMVSS 116)\" tabindex=\"0\">\n        <table class=\"compare-table\">\n          <caption>Minimum brake fluid boiling points by DOT rating (FMVSS 116)<\/caption>\n          <thead>\n            <tr><th scope=\"col\">Rating<\/th><th scope=\"col\">Minimum dry boiling point<\/th><th scope=\"col\">Minimum wet boiling point<\/th><th scope=\"col\">Base<\/th><\/tr>\n          <\/thead>\n          <tbody>\n            <tr><th scope=\"row\">DOT 3<\/th><td>401\u00b0F (205\u00b0C)<\/td><td>284\u00b0F (140\u00b0C)<\/td><td>Glycol<\/td><\/tr>\n            <tr><th scope=\"row\">DOT 4<\/th><td>446\u00b0F (230\u00b0C)<\/td><td>311\u00b0F (155\u00b0C)<\/td><td>Glycol<\/td><\/tr>\n            <tr><th scope=\"row\">DOT 5.1<\/th><td>500\u00b0F (260\u00b0C)<\/td><td>356\u00b0F (180\u00b0C)<\/td><td>Glycol (non-silicone)<\/td><\/tr>\n            <tr><th scope=\"row\">DOT 5<\/th><td>Not compared here<\/td><td>Not compared here<\/td><td>Silicone (don't mix with glycol fluids)<\/td><\/tr>\n          <\/tbody>\n        <\/table>\n      <\/div>\n\n      <p>A \"racing DOT 4\" such as Motul RBF 660 carries a DOT 4 rating because it meets every DOT 4 requirement, but it beats the minimum dry boiling point by a wide margin. So a DOT 5.1 label doesn't automatically mean a better brake fluid for track days: RBF 600's 594\u00b0F dry figure is well above the DOT 5.1 minimum of 500\u00b0F.<\/p>\n\n      <p>DOT 5 is a different chemistry.

It meets FMVSS 116 DOT 4, SAE J1703 and ISO 4925. For most street-driven HPDE cars, it's the fluid to beat.<\/p>\n\n      <p><strong>RBF 660.<\/strong> Dry boiling point rises to 617\u00b0F (325\u00b0C). Motul's current data sheet lists the wet boiling point as 401\u00b0F (205\u00b0C); one regional Motul product page shows 400\u00b0F (204\u00b0C). Motul says it's also suitable for conventional brakes with steel rotors.<\/p>\n\n      <p><strong>RBF 700.<\/strong> Motul's data sheet gives 637\u00b0F (336\u00b0C) dry and 401\u00b0F (205\u00b0C) wet. Motul developed it for \"extreme brake temperatures generated by carbon and ceramic racing brake discs systems,\" and notes that it meets DOT 4, \"allowing the fluid to be used in high performance vehicles for everyday use road applications.\"<\/p>\n\n      <p>Wet boiling points are nearly identical, about 400\u00b0F to 401\u00b0F. The extra money buys dry boiling point: 23\u00b0F from RBF 600 to 660, then another 20\u00b0F to RBF 700. That matters most for heavy cars, sticky tires and endurance stints.<\/p>\n\n      <p>Our Motul RBF listings are sold by the case: each SKU is twelve 500 ml bottles. That works out to roughly $23.58 a bottle for RBF 600, $32.35 for RBF 660 and $38.57 for RBF 700 at the case prices in the table below. If you only need a bottle or two for a flush, the Brembo, Wilwood and EBC fluids below are sold individually.<\/p>\n\n\n      <!-- Section 4 -->\n\n      <h2 id=\"other-track-fluids\">Other Track Fluids We Carry: Brembo, Wilwood and EBC<\/h2>\n\n      <p><strong>Brembo LCF 600 Plus.<\/strong> Brembo gives a \"typical dry boiling point of 312\u00b0C (593\u00b0F)\" and says it exceeds FMVSS 116 DOT 4.

Castrol's Canadian data sheet says it exceeds FMVSS 116 DOT 3 and DOT 4 and lists a dry equilibrium reflux boiling point of 320\u00b0C (608\u00b0F) and a wet figure of 270\u00b0C (518\u00b0F). Castrol's Canadian product page quotes the dry boiling point as 325\u00b0C (617\u00b0F).<\/p>\n\n      <p>That wet number is much higher than the glycol fluids above. Castrol credits a \"unique silicon ester technology\" that \"absorbs less water than conventional glycol ether fluids,\" and says SRF should be used for no more than eighteen months before draining and refilling. Don't confuse that with silicone DOT 5: SRF is rated DOT 3 and DOT 4, and Castrol's data sheet says it's miscible with conventional DOT 3 and DOT 4 fluids. SRF isn't part of our brake fluid lineup, so we can't quote you a price.<\/p>\n\n\n      <!-- Section 6 -->\n\n      <h2 id=\"bleed-and-flush\">How Often to Change Brake Fluid on a Track Car<\/h2>\n\n      <p>There's no single right interval. Motul's RBF 660 data sheet says to tune it \"to your own use.\" Here's what the fluid makers publish:<\/p>\n\n      <ul class=\"bf-list\">\n        <li><strong>Wilwood:<\/strong> \"For street cars, flush and refill the fluid every year. For race or track driven cars it can be beneficial to change the fluid after every race weekend, especially after racing in the rain, severe temperature use, or brake fluid boiling.\"<\/li>\n        <li><strong>Wilwood (EXP flyer):<\/strong> \"In extreme service, best performance is realized by flushing and filling the system with fresh fluid immediately before competition. Always use fluid from a previously unopened container.\"<\/li>\n        <li><strong>Castrol:<\/strong> use SRF for no more than eighteen months before draining and refilling.<\/li>\n      <\/ul>\n\n      <p>In practice, most track cars fall somewhere on this scale:<\/p>\n\n      <ol class=\"bf-list\">\n        <li><strong>Before your first event on a new fluid:<\/strong> do a full flush, not a top-up. Brembo recommends completely emptying the old fluid before switching to LCF 600 Plus.<\/li>\n        <li><strong>Before each event:<\/strong> bleed each caliper until the fluid runs clean and bubble-free.<\/li>\n        <li><strong>After a session where the pedal went long:<\/strong> assume the fluid boiled. Bleed before going back out.<\/li>\n        <li><strong>Regardless of track time:<\/strong> flush within the maker's time limit, such as 12 months for Wilwood EXP.<\/li>\n      <\/ol>\n\n      <p>If the pedal feels the same at the end of the day as in the morning, your interval and your brake fluid for track days are both doing their job. If it gets longer, bleed more often or step up in dry boiling point.<\/p>\n\n\n      <!-- Section 7 -->\n\n      <h2 id=\"pads-fluid-rotors\">Pads, Fluid and Rotors Work as a System<\/h2>\n\n      <p>A track pad that keeps biting at higher temperatures also lets the caliper and fluid get hotter. A pad upgrade without a fluid upgrade often just moves the weak link: the pads hold on and the fluid boils.<\/p>\n\n      <p>Running PowerStop pads? Here's how we'd match the fluid to the pad:<\/p>\n\n      <ul class=\"bf-list\">\n        <li><strong>PowerStop Track Day (Stage 1, street-to-track):<\/strong> pair with RBF 600 or Wilwood EXP 600 Plus.<\/li>\n        <li><strong>PowerStop Track Day SPEC (Stage 2, track cars and R-comps):<\/strong> step up to RBF 660 or RBF 700 and bleed every weekend.<\/li>\n      <\/ul>\n\n      <p>Our <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/powerstop-track-day-vs-track-day-spec\/\">PowerStop Track Day vs Track Day SPEC comparison<\/a> explains which pad fits which driver. <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/how-powerstop-brake-kits-are-built\/\">How PowerStop brake kits are built<\/a> covers the rotor side.

If you bleed before every event and have never had a long pedal on RBF 600, the extra 23\u00b0F may never come into play. If you're boiling RBF 600 late in sessions on sticky tires or in a heavy car, RBF 660 is the logical next step.<\/p>\n\n      <h3>What brake fluid do I need for my first track day?<\/h3>\n\n      <p>A fresh, full flush of a quality high-temperature DOT 4 matters more than the brand. Old, moisture-laden factory fluid often causes a soft pedal at a first event. Motul RBF 600 and Wilwood EXP 600 Plus both suit a street car that's driven to the track. Flush a week before the event so you can check for leaks. Our <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/preparing-for-track-day\/\">Preparing for Track Day guide<\/a> covers the rest of the checklist.<\/p>\n\n      <h3>Can I mix brake fluid brands?<\/h3>\n\n      <p>Within the same chemistry, some makers allow it. Wilwood says EXP 600 Plus is \"fully miscible with all other DOT 3 and 4 rated racing fluids.\" Brembo says LCF 600 Plus can be mixed with other racing DOT 3 and DOT 4 fluids, but recommends emptying the system completely. EBC says not to mix BF307+ with other fluids. Motul's data sheets say to avoid mixing RBF 660 with lower-performance polyglycol fluids and to avoid mixing RBF 700 with polyglycol fluids at all. A full flush gives you the boiling point on the bottle.<\/p>\n\n      <h3>How often should I bleed brakes for track days?<\/h3>\n\n      <p>Many track drivers bleed before every event. Wilwood says that for race or track cars \"it can be beneficial to change the fluid after every race weekend,\" especially after rain, severe heat or boiling the fluid. If your pedal went long during a session, bleed before you go back out. Beyond that, let pedal feel and session count set the schedule.<\/p>\n\n      <h3>Is DOT 5.1 the same as DOT 5?<\/h3>\n\n      <p>No. DOT 5.1 is a glycol-based fluid like DOT 3 and DOT 4, and Motul's data sheets describe it as \"non-silicone base.\" DOT 5 is silicone-based. Wilwood warns that DOT 5 is not compatible with glycol-based DOT 3, DOT 4 or DOT 5.1 fluids and \"will turn to gel if mixed.\" Never add DOT 5 to a glycol system. If your car specifies DOT 5.1, note that Motul says RBF 660 exceeds DOT 5.1 requirements except for viscosity at -40\u00b0F (-40\u00b0C). Low-temperature viscosity is what DOT 5.1 adds for ABS and stability systems, so check your owner's manual before switching.<\/p>\n\n      <h3>Can I daily-drive on racing brake fluid?<\/h3>\n\n      <p>Read the label. Motul says RBF 700 meets DOT 4 and can be used \"for everyday use road applications,\" and EBC markets BF307+ for \"fast street use\" as well as track days. Brembo LCF 600 Plus is the opposite: Brembo says it's \"not suitable for use in vehicles travelling on public roads or motorways.\" Either way, the same moisture rules apply, so flush on schedule.<\/p>\n\n\n      <hr class=\"section-rule\">\n\n      <div class=\"cta-block\">\n        <h3>Shop Track Brake Fluid at Track Ready Products<\/h3>\n        <p>Shop track brake fluid, or text us your car, pads and run group at <strong>(949) 954-3322<\/strong> and we'll recommend a fluid and bleed schedule.<\/p>\n        <div class=\"cta-actions\">\n          <a href=\"https:\/\/www.trackreadyproducts.com\/brake-fluid-c-792_854\/\">Browse our track brake fluid selection<\/a>\n          <a href=\"https:\/\/www.trackreadyproducts.com\/brake-pads-racing-c-792_850\/\" class=\"secondary\">Shop racing brake pads<\/a>\n          <a href=\"https:\/\/www.trackreadyproducts.com\/powerstop-m-36.html\" class=\"secondary\">Shop PowerStop brakes<\/a>\n        <\/div>\n      <\/div>\n\n    <\/article>\n\n    <!-- SIDEBAR -->\n    <aside class=\"bf-sidebar\" aria-label=\"Article navigation and related links\">\n      <div class=\"sidebar-sticky\">\n\n        <div class=\"sidebar-widget\">\n          <div class=\"widget-head\">Navigation<\/div>\n          <div class=\"widget-body\">\n            <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/powerstop-brakes\/\" class=\"back-link\">Back to the PowerStop brakes hub<\/a>\n          <\/div>\n        <\/div>\n\n        <a href=\"https:\/\/www.trackreadyproducts.com\/brake-fluid-c-792_854\/\" class=\"sidebar-cta-btn\">Shop brake fluid<\/a>\n\n        <div class=\"sidebar-widget\">\n          <div class=\"widget-head\">At a Glance<\/div>\n          <div class=\"widget-body\">\n            <div class=\"sidebar-stat-item\"><span class=\"s-label\">Best all-rounder<\/span><span class=\"s-val\">Motul RBF 600 (594\u00b0F dry)<\/span><\/div>\n            <div class=\"sidebar-stat-item\"><span class=\"s-label\">Highest dry boiling point<\/span><span class=\"s-val\">Motul RBF 700 (637\u00b0F dry)<\/span><\/div>\n            <div class=\"sidebar-stat-item\"><span class=\"s-label\">Lowest bottle price, 590\u00b0F+ dry<\/span><span class=\"s-val\">Wilwood EXP 600 Plus ($26.53 \/ 500 ml)<\/span><\/div>\n            <div class=\"sidebar-stat-item\"><span class=\"s-label\">Bleed interval<\/span><span class=\"s-val\">Before each event; flush after any boil<\/span><\/div>\n          <\/div>\n        <\/div>\n\n        <nav class=\"sidebar-widget\" aria-label=\"In this article\">\n          <div class=\"widget-head\">In This Article<\/div>\n          <div class=\"widget-body\">\n            <ul class=\"toc-list\">\n              <li><a href=\"#why-fluid-fades\">Why Fluid Fades<\/a><\/li>\n              <li><a href=\"#dot-ratings\">DOT Ratings<\/a><\/li>\n              <li><a href=\"#motul-rbf-600-vs-660-vs-700\">RBF 600 vs 660 vs 700<\/a><\/li>\n              <li><a href=\"#other-track-fluids\">Brembo, Wilwood &amp; EBC<\/a><\/li>\n              <li><a href=\"#castrol-srf\">Castrol SRF<\/a><\/li>\n              <li><a href=\"#bleed-and-flush\">Bleed &amp; Flush<\/a><\/li>\n              <li><a href=\"#pads-fluid-rotors\">Pads, Fluid &amp; Rotors<\/a><\/li>\n              <li><a href=\"#faq\">FAQ<\/a><\/li>\n            <\/ul>\n          <\/div>\n        <\/nav>\n\n        <div class=\"sidebar-widget\">\n          <div class=\"widget-head\">Related Articles<\/div>\n          <div class=\"widget-body\">\n            <div class=\"related-post\">\n              <div class=\"r-tag\">Comparison<\/div>\n              <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/powerstop-track-day-vs-track-day-spec\/\">PowerStop Track Day vs Track Day SPEC<\/a>\n            <\/div>\n            <div class=\"related-post\">\n              <div class=\"r-tag\">Track Guide<\/div>\n              <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/street-car-to-track-car-the-real-order-of-operations\/\">Street Car to Track Car: The Real Order of Operations<\/a>\n            <\/div>\n            <div class=\"related-post\">\n              <div class=\"r-tag\">How-To<\/div>\n              <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/preparing-for-track-day\/\">Preparing for Track Day<\/a>\n            <\/div>\n            <div class=\"related-post\">\n              <div class=\"r-tag\">Brand Overview<\/div>\n              <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/how-powerstop-brake-kits-are-built\/\">How PowerStop Brake Kits Are Built<\/a>\n            <\/div>\n          <\/div>\n        <\/div>\n\n      <\/div>\n    <\/aside>\n\n  <\/div><!-- .bf-page-wrap -->\n<\/div><!-- .bf-post -->\n","protected":false},"excerpt":{"rendered":"<p>Choosing brake fluid for track days comes down to one problem: fluid that boils.
