Overview
The Baer Brakes 4302485R is a red Pro Plus 14-inch rear brake system for 1960-1986 Chevy and GMC C10 trucks with five-lug, 5×5.00 wheels. Its 6-piston caliper and slotted, drilled 14-inch rotor are intended for rear-axle use on 2WD trucks.
A single backing plate holds the caliper and a one-piece park brake shoe assembly, keeping the parking brake integrated with the rear unit. Rotors come pre-assembled with NAS high-grade stainless hardware. The rotor is designed for wheels 18 inches and up, but wheel style can affect fit, so test the template first.

Rear brake wear and upkeep
Rear brakes on a truck of this era do a large share of the work when the vehicle is loaded or towing, and they wear unevenly compared with the front. Signs that the rear needs attention include pulsing or grinding under braking, a pedal that feels softer than before, pads worn close to the backing plate, and scoring or a raised lip on the rotor face. Check the rotor for thickness and runout whenever pads are changed, since a worn rotor can cause the same symptoms as worn pads.
Because the park brake shoes sit inside the backing plate on this type of system, the parking brake should be checked along with the service brakes. Adjust it after any drum or shoe work and confirm it holds the vehicle on a grade before relying on it. Keep the wheel bearings, hub seals and brake lines in view during each service, since a leak or loose bearing can ruin new friction parts quickly.
- Replace pads and rotors as a matched set where possible
- Inspect braided hoses for chafing or bulges
- Re-torque wheel lug nuts after the first few drives
