Overview
Fire Red is the finish on Baer’s 4302542FR, a rear disc brake kit for Chevrolet and GMC C10-series trucks from 1960 to 1988 in 2WD form. The package pairs a 13-inch two-piece rotor with a 6-piston floating caliper, and its backing plate also holds the park brake shoes.
The rear rotor outside diameter is 13.0 inch, which matches a rear-axle system. The mounting uses the OE large pattern 10/12 bolt C-clip housing ends and a six-lug, 6×5.50 inch bolt pattern. Stainless braided hoses and stainless hardware come with the set, and the kit is a performance-grade system.

- Performance grade type
Performance grade braking
A performance grade rear brake system is mainly about how the parts handle repeated heavy stops rather than one hard stop. Consistent pad contact, rotor cooling and hydraulic response all matter when the truck is loaded or driven hard down a grade. Pad choice should match that use, because a compound built for high heat may feel different when cold.
Stainless braided hoses hold their shape under pressure better than rubber lines, which helps keep pedal feel consistent over time. The hoses should be routed clear of moving parts and heat sources, and inspected each time the wheels come off. Bleeding the system after installation removes air that would otherwise soften the pedal.
Vented rotors help shed heat during repeated stops, but they still need a clean, true surface to work well. Glazing from overheating or contamination from grease can reduce grip, so check the surfaces after any fluid leak. Replacing pads and rotors as a matched set keeps wear even across both sides of the axle.
- Bleed the system after any hose or caliper work
- Route hoses clear of moving parts and exhaust heat
- Replace pads and rotors together to keep wear even
- Keep grease off pads and rotor friction surfaces

Vehicle fitment
Sorted by start year, the manufacturer list opens with the 1960–1986 Chevrolet C10, the 1960–1965 GMC 1000 Series and the 1960–1966 GMC Suburban, then moves through the 1966 GMC 1000 and the 1967 C10 and C15 entries. It ends with the 1987–1988 Chevrolet R10 Suburban and GMC R1500 Suburban.
Four-wheel-drive versions and model years outside the listed ranges are not part of this fitment. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Rotors are pre-assembled and the set includes stainless hardware, so the bolt-on work centers on the caliper and backing plate. Park brake cables are not included. The 17.0 inch minimum wheel diameter applies, and the Q135H template is the listed reference for checking wheel fit. Work on the brakes only with the truck safely supported.
What’s included
The set includes the 6-piston rear brake system, the pre-assembled vented rotor with billet aluminum hat, the backing plate with park brake shoe assembly, and stainless braided hoses with stainless hardware.
Not included: Park brake cables.
