Overview
Comp Yellow is the finish option on the Baer Brakes 4302541CY, a Pro Plus 13.0 inch rear brake system for Chevy and GMC C10 2WD trucks from 1960 to 1987. The kit is built around a six-piston 6P caliper that squeezes a 13 inch two-piece slotted, drilled and zinc-plated rotor, and it is set up for 5 lug hubs on a 5×5 inch bolt pattern.
Baer manufactures the caliper in Phoenix, Arizona. The backing plate carries the caliper and also holds a one-piece park brake shoe assembly. Rotors are delivered pre-assembled with NAS high grade stainless hardware, so the hat and fasteners arrive ready to mount. The system is designed for Large Pattern 10/12 bolt C-clip housing ends at the rear.
Key features

- Six-piston 6P floating caliper with stainless steel pistons

- Two-piece slotted, drilled and zinc-plated rotor with billet aluminum hat
- One-piece park brake shoe assembly housed in the backing plate

Choosing the right setup
A rear disc setup changes how the truck stops and how the axle carries load, so the parts around the caliper matter as much as the rotor. Before buying, look at the wheel style you plan to run, the housing ends on your axle, and whether the existing parking brake hardware is still in good shape. Many owners who convert a drum rear also replace the brake lines and hub bearings during the same job, since those parts are exposed once the axle is apart.
Once installed, a disc setup needs regular inspection. Check the pads for even wear, look at the rotor surface for heat cracking or deep grooves, and listen for scraping after the first few drives. Re-check the caliper bolts and wheel lug nuts after the first short trips, because fasteners can settle as new parts seat. Keep the brake fluid fresh, since moisture in old fluid lowers its boiling point under heavy braking.
- Pad material suited to your driving
- Brake hose condition at the caliper
- Park brake cable routing and adjustment
- Wheel clearance with the caliper at full lock

Installation notes
This kit has to match the rear housing it was designed for, so check the bolt pattern and housing style before starting. Because the park brake shoe is built into the backing plate, cable routing becomes the main job when reusing your existing hardware. Use a torque wrench and stands while working at the rear axle.
What’s included
The kit includes the 6P caliper and backing plate, the pre-assembled 13.0 inch rotor, the one-piece park brake shoe assembly, and braided brake hoses with hardware.
Not included: park brake cables.
