Overview
The Baer Brakes 4302541B is a black-finished Pro Plus 13.0 inch rear disc brake kit for GM C10 trucks, 2WD models built from 1960 to 1987 with a 5×5 inch wheel bolt pattern and five lug hubs. Its six-piston 6P caliper is fitted to a 13 inch two-piece rotor that is slotted, drilled and zinc plated.
The caliper is manufactured in Phoenix, Arizona, and the system uses CNC machined forged or billet aluminum components. Baer’s backing plate mounts the caliper and houses a modern one-piece park brake shoe assembly. The rear uses Large Pattern 10/12 bolt C-clip housing ends, and each rotor comes assembled with high grade NAS stainless fasteners.
Key features
- Black powder coated finish on the caliper
- Six-piston 6P caliper on a 13.0 inch two-piece rotor
- Slotted, drilled and zinc-plated rotor surface on a billet aluminum hat
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons for more even pad wear
- Dual dust, weather and pressure seals
- Integrated park brake shoe assembly inside the backing plate
Things to check
Start every inspection with the basics: the caliper, the rotor surface, the pads and the hoses. A caliper that pulls to one side may have a stuck piston or a restricted hose. Rotors that show deep grooves or a blue tint from heat should be measured against the minimum thickness given in the service manual.
Park brake function is worth testing after every service. Park the truck on a slight grade, set the brake and confirm it holds. If it creeps, the parking shoe adjustment or cable routing needs attention before the truck is driven again.
Brake hoses flex with every suspension movement, so inspect them for cracks, bulges and rubbing against the frame or axle. Replace any hose that shows wear rather than waiting for a failure, since a failed hose can leave a corner without braking.

Installation notes
A 17 inch or larger wheel is needed, so check clearance with the Q135H template before mounting a wheel. The backing plate holds the park brake shoe, which means park brake cables are not supplied and must be reused or sourced separately. Brake work at the rear axle calls for a supported vehicle and the right tools.
What’s included
The rear brake kit includes the 6P caliper and backing plate with the one-piece park brake shoe, the 13.0 inch rotor with pre-assembled hardware, and braided brake hoses with hardware.
Not included: park brake cables.
