Overview
Grabber Blue is the finish on the Baer Brakes 4302541GB, a Pro Plus 13.0 inch rear disc brake kit for 2WD Chevy and GMC C10 trucks built from 1960 through 1987. Each kit uses a six-piston 6P caliper and a 13 inch two-piece rotor, and it is set up for the 5×5 inch wheel bolt pattern.
The 6P caliper is manufactured in Phoenix, Arizona. Baer machines the parts from US sourced forged or billet aluminum, and the rotor hat is billet aluminum as well. The kit is built for Large Pattern 10/12 bolt C-clip housing ends at the rear axle, and its backing plate both mounts the caliper and holds a modern one-piece park brake shoe assembly.
Key features
- Six-piston 6P caliper with staggered pistons that help even out pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Powder coated Grabber Blue caliper finish
- Slotted, drilled and zinc-plated two-piece rotor on a billet aluminum hat
- Dual seals against dust, weather and pressure
- One-piece park brake shoe built into the backing plate
- Braided brake hoses, DOT approved, with hardware supplied
Choosing the right setup
Disc brakes on the rear of a C10 work best when the rest of the braking system is balanced. Pedal feel depends on the front brakes, the master cylinder and any proportioning valve, so review those parts when you plan the conversion. A rear disc setup also changes how heat moves through the axle, which makes a good quality pad choice worthwhile.
The park brake is handled differently on this style of kit. Because the parking shoe lives in the backing plate, plan the cable routing early and check that the cables reach the lever without binding. Keep the parking function in mind during any future service.
Owners who drive mostly on paved roads may want a different pad compound than those who tow or run hilly routes. Pick pads to match how the truck is used rather than the cheapest option available.

Installation notes
Check the Q135H template against your chosen wheel, since clearance depends on wheel design even though the kit is rated for wheels 17 inches and larger. The park brake shoe lives in the backing plate, so park brake cables must come from your existing setup or a separate source. Keep the truck supported on stands while you work at the rear.
What’s included
The kit contains the rear 6P caliper and backing plate with the integrated park brake shoe, the 13.0 inch rotor with pre-assembled NAS stainless hardware, and braided brake hoses with hardware.
Not included: park brake cables.
