Overview
The Baer Brakes Pro Plus 14.0 inch rear brake system, part number 4302342CY, is a complete rear disc brake kit in Comp Yellow for rear axles with a GM small pattern 10/12 bolt flange and flush mount bearing housing. It pairs a 6-piston fixed caliper with a 14 inch two-piece slotted, drilled and zinc plated rotor, and it uses the D0731 pad type.
The backing plate serves as the caliper mount and houses a one-piece park brake shoe assembly, so the parking brake is built into the rear brake assembly. The kit fits 5×4.75 and 5×5.00 bolt patterns with 5 lug nuts and suits wheels with a minimum diameter of 18.0 inch. Not every wheel style will clear it, so compare your wheel with the Q110P template before mounting.

Pad and rotor wear
Brake pads and rotors wear together, so inspect both at each service on a rear disc setup like this one. The staggered pistons help spread pressure across the pad, but uneven wear can still appear when slide pins are dry or the caliper drags. Look for pad thickness that differs from side to side, blue or heat-stained rotor faces, and a pulsing pedal under light braking. Those signs often point to a sticking caliper or a warped rotor that needs attention before the next long drive.
Rear park brake shoes are easy to overlook during routine work. Because the shoe assembly sits inside the backing plate, check its adjustment and lining condition whenever the rear hub comes off. Recheck the caliper bracket and backing plate bolts after the first few drives on new hardware. Keep a note of pad thickness at each check so wear can be tracked over time.
