Overview
The Baer Brakes Pro Plus rear brake system, part number 4302249GB, is a rear disc brake kit with a 6-piston, 6P floating caliper in Grabber Blue. It clamps a 14-inch, 2-piece slotted, drilled and zinc plated rotor and is made for rear ends with a GM small car pattern 10/12 bolt C-clip flange and 5×4.75/5×5.00 wheel bolts.
Each caliper is manufactured in Phoenix, Arizona, from CNC machined forged or billet aluminum with a powder coated finish. The system uses D0731 brake pads, and the rotor carries a billet aluminum hat as part of its two-piece construction.
Key features
- 6-piston, 6P floating caliper with staggered pistons
- Stainless steel pistons, abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- 2-piece slotted, drilled, zinc plated rotor with billet aluminum hat
- Backing plate that doubles as the caliper mount and houses a 1-piece park brake shoe
- Braided hoses with hardware included
Park brake setup
The park brake function on a rear disc system depends on the shoes inside the backing plate, the cables that connect to them and the adjuster that keeps the shoes close to the drum surface. When the rotor and caliper are replaced, the park brake system should be checked as a whole rather than as a single part. Cable routing, lever travel and shoe adjustment all affect how well the parking brake holds.
Trail and off-road use puts more load on the parking brake than daily driving does. Mud, water and grit can enter the backing plate and seize an adjuster, so inspect the area after deep water crossings. Keep cable housings clear of heat sources and sharp edges, and check shoe adjustment after the first few trail runs following any park brake work.
- Plan cables and routing before installation
- Check shoe adjustment after rear brake service
- Inspect the backing plate after water or mud exposure

Vehicle fitment
This kit is matched to the rear end rather than a model or year. It is intended for rear axles with a GM small car pattern 10/12 bolt C-clip flange and 5×4.75/5×5.00 wheel bolts. The 14-inch rotor fits most wheels 18 inches or larger.
Confirm your vehicle’s year, model and trim before ordering. Use template Q110P to compare the wheel you plan to run.
Installation notes
Each rotor is supplied assembled with NAS high-grade stainless fasteners. Parking brake cabling is outside this kit’s contents, so it must be arranged separately.
What’s included
The kit includes the 6P caliper, the backing plate with a 1-piece park brake shoe assembly, the pre-assembled 14-inch rotor, and braided hoses with hardware.
Not included: Park brake cables.
