The Hawk LTS Street Rear Brake Pad (HB323Y.724) is a ferro-carbon friction pad built for full-size light trucks, SUVs, and vans, and the manufacturer lists it as a street compound. Its strong, balanced initial bite whether hot or cold, greater fade resistance, low dust output, and excellent pad and rotor life are the reasons to choose it over a standard replacement pad. Owners on user forums who ran this compound with upgraded rotors report quiet brakes and call the upgrade worth it, even at its higher price. Because it is a rear-axle pad, a buyer searching for a Hawk LTS rear pad for a 2500-series Silverado, Sierra, Suburban, or Yukon XL should confirm the fitment list before ordering.
The manufacturer's rear fitment list covers 2000 through 2013 model-year Chevrolet, GMC, and Hummer full-size trucks and SUVs, including Suburban 2500, Yukon XL 2500, and H2 applications. The pads are intended for street use and work with stock calipers, stock rotors, slotted rotors, and cross-drilled rotors, and they do not include shims or hardware. The manufacturer also notes that Hawk pads are designed to work with iron or metal rotors, so they should not be paired with carbon ceramic rotors. Drivers chasing the best pad-to-rotor match for a towing or heavy-commute setup on a Silverado 2500HD or Sierra 2500HD should search for long-tail terms such as "HB323Y.724 rear pads 2500HD" or "Hawk LTS street pad iron rotor."
For the install, the manufacturer's FAQ recommends that rotors be turned or machined, washed and dried, pads installed securely, and the pads bedded in properly before the truck returns to normal use. For street pads, the manufacturer's bed-in routine calls for 6 to 10 stops from 30-35 mph using moderate brake pressure, followed by 2 to 3 hard stops from 40-45 mph, then 15 minutes of cooling. Skipping that step can leave a glazed pad surface with a cloudy, glassy look and dramatically reduced stopping ability. Searches such as "LTS brake pad bedding procedure" or "Hawk rear brake pad install tips" will bring up the same procedure.
No. The manufacturer states that its compounds, including the LTS, are not compatible with carbon ceramic rotors and are designed for iron or metal rotors.
The manufacturer's rear fitment list includes Silverado 2500 HD, Sierra 2500 HD, Suburban 2500, Yukon XL 2500, and Hummer H2 applications across multiple model years. Confirm your exact year, trim, and rear-axle application against the manufacturer's fitment list before ordering.
Yes. The manufacturer recommends a street bed-in of 6 to 10 moderate stops from 30-35 mph, followed by 2 to 3 harder stops from 40-45 mph, and then a 15-minute cool-down period without dragging the brakes.
This is a straightforward pad swap for a home mechanic with basic brake experience, and owners on user forums often describe the job as simple. Plan on a jack and jack stands, a lug wrench, a caliper piston compression tool or C-clamp, a wire or bungee cord to support the caliper, and brake cleaner. Before installing, inspect the rotors for thickness, scoring, and run-out, and resurface or replace them if needed, since the manufacturer's FAQ lists machining as a prep step. Clean the rotor face with soap and water to remove any leftover pad material, and check that the caliper slides move freely and are lubricated where needed. Ensure the new pads sit fully in the bracket and caliper, then complete the bed-in routine above before driving normally.
