Product Details

The Raybestos R-Line is the company’s replacement-focused product line for everyday brake service needs. DPS85032 is a steel disc brake caliper piston intended for front brake hydraulics on many domestic passenger cars, trucks, and vans. Confirmed applications include 1997-2003 Chevrolet Blazer front, 1997-2003 Chevrolet S10 front, 1997-2003 GMC Sonoma front, 1996-2000 Isuzu Hombre front, 1992-1997 GMC Jimmy front, and 1984-1996 Buick Century front. This part number, DPS85032, also covers older front brake applications such as Chevrolet Camaro, Pontiac Firebird, Buick Regal, and Oldsmobile Cutlass models listed in the fitment data.

What It Helps Fix

  • Brake drag caused by a worn or sticking caliper piston
  • Hydraulic leakage at the caliper piston area
  • Uneven front brake pad wear from piston binding
  • Poor brake pedal response related to caliper piston wear
  • Front brake service needs on vehicles with drum or disc brake configurations listed in fitment

Installation Notes and Tips

Verify the original caliper piston material and front brake configuration before ordering. Match the vehicle year, make, model, and brake setup exactly, since some listings include notes such as rear drum brakes, standard duty drum brakes, or non-heavy-duty brake systems. For example, this part fits 1997-2003 Chevrolet Blazer, front; 1997-2003 Chevrolet S10, front; and 1997-2003 GMC Sonoma, front. Always inspect the caliper bore, seals, and brake fluid condition during service, and bleed the hydraulic system after installation.

Quality Assurance

Raybestos backs the R-Line as a replacement brake parts line for service applications. DPS85032 is a steel caliper piston built to meet the needs of listed front brake repairs across the confirmed fitment range.
