Overview
The Baer Brakes Pro Plus rear brake system, part number 4302532B, is a 6-piston rear disc kit for 1988–1998 Chevrolet and GMC C1500 2WD trucks and 1992–1999 C1500 2WD Suburban and Yukon models with the factory C-clip rear end and 10 inch rear drums. It mounts a 6P caliper on a 14 inch two-piece rotor, and the park brake shoe assembly is housed inside the Baer backing plate.
The backing plate serves as the caliper mount and holds a modern one-piece park brake shoe. Rotors arrive pre-assembled with NAS high grade stainless hardware, and stainless braided hoses with hardware are included. Because wheel styles vary widely, compare the Q135P template with your wheel of choice before ordering. The 14 inch rotor fits most wheels 18 inch or larger.

Rear disc conversion basics
Converting a rear drum axle to disc changes how the rear brakes share work with the front. Disc rear brakes generally shed heat faster than drums, which helps when the truck is loaded, towing, or driven down long grades. The rotor and caliper sit outside the drum area, so the parking brake needs its own shoe, which is why a park brake assembly is part of this kit.
Before installation, check the rear axle bearings, axle seals and brake lines, since a conversion often exposes parts that were not serviced with the drums. Watch pad wear at regular intervals and check fluid level after the first bleed. Once the system is in place, a bed-in procedure helps the pads lay an even transfer layer on the rotor.
- Inspect rotor surfaces for scoring or heat cracks
- Torque lug nuts again after the first few drives
- Replace hoses that show cracking or bulging
- Bleed the system after any hose or caliper work
