Overview
The Baer Brakes 4302504R is a complete Pro Plus 14.0 in rear brake system in Red for 60-87 Chevy and GMC C10 2WD trucks. It pairs a 6-piston, 6P caliper with a 14 inch, 2-piece slotted, drilled, zinc-plated rotor, so the caliper and rotor arrive as one rear kit for these trucks.
The backing plate serves as the caliper mount and houses a modern 1-piece park brake shoe assembly. The kit uses the D0731 disc brake pad type, and the caliper carries dust and weather seals. The 14 inch Pro Plus is intended for wheels of 18 inches or larger, so wheel choice matters for this system.
Key features
- Six-piston 6P caliper with staggered pistons to minimize uneven pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Dual seals guard against dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor with a billet aluminum hat
- Rotors arrive pre-assembled with NAS high grade stainless hardware
- Baer backing plate houses a 1-piece park brake shoe assembly
- Stainless braided hoses and hardware are included
- Components are CNC machined from US-sourced forged or billet aluminum, with a powder coated finish
Choosing wheels and clearance
Wheel choice affects more than looks on a rear brake upgrade. The caliper and rotor must clear the inside of the wheel with room for the hub face and spokes, and wheel offset can bring the tire closer to the caliper. Measure clearance before buying tires, and recheck it after any wheel or tire change.
Pads and rotors wear together, so inspect both during each brake service. Rotors with deep grooves, heat cracks or thickness below the minimum should be replaced rather than reused. Replacing pads with the rotors often keeps braking even. Check hoses for cracks and fittings for seepage whenever the wheels come off.
- Measure wheel clearance with the caliper installed
- Inspect pads and rotor faces at each service
- Check hoses for chafing and cracks
- Confirm park brake cable routing before the first drive
