Wilwood's Hi-Temp 570 is a racing brake fluid sold as a six-pack of 12 oz bottles, a practical size for racers who refresh their fluid often. The manufacturer lists a minimum 570°F dry boiling point and a 313°F wet boiling point, and its low viscosity helps resist aeration and foaming when the pedal is worked hard. Compared with a generic street fluid, the higher dry boiling point is meant to keep the pedal firm when brakes run hot through repeated track laps, HPDE sessions, or autocross runs. Owners on user forums have reported a clear pedal improvement over stock fluid on track days. This is a universal-fit fluid, so it suits Wilwood calipers and master cylinders as well as other hydraulic systems that call for a compatible DOT rating, including ABS-equipped track cars. Before ordering, confirm the current DOT rating with the manufacturer, because its published literature lists both DOT 3 and DOT 5.1 for this formula. Do not use it where silicone DOT 5 fluid is specified.
For a DIY bleed, the manufacturer's install guidance is to fill and bleed the new system with Hi-Temp 570 or higher, and to flush used fluid completely so the new fluid is not contaminated. Start at the caliper farthest from the master cylinder, bleeding the outboard screw before the inboard one. Owners on user forums advise pumping the pedal gently instead of stroking it repeatedly, since pumping aerates the fluid. Use a catch hose on every bleeder to keep spills off the bodywork, and keep fluid away from pad and rotor contact surfaces. Long-tail searches this product matches include "570 racing brake fluid six pack," "high dry boiling point track brake fluid," "Wilwood brake bleeding sequence," and "DOT 3 racing brake fluid for ABS."
The manufacturer advises against mixing different DOT ratings, so a full flush is the safer approach when changing fluid types.
No. The manufacturer states that this fluid should not be used where silicone DOT 5 fluid is specified.
The manufacturer's install guidance is to begin with the caliper farthest from the master cylinder, bleeding the outboard screw first and then the inboard screw.
Bleeding is a two-person job for most cars. Use a clear catch hose on each bleeder, keep the master cylinder reservoir topped up so air is not drawn in, and check all fittings for leaks afterward. Pumping the pedal aerates the fluid, so press slowly and hold before releasing. Wilwood's install sheet also calls for a complete flush of any used fluid before the new fluid goes in. Brake fluid can damage painted surfaces, so wipe up spills immediately.
