Overview
The Baer Brakes 4302248GB is a Grabber Blue rear disc brake kit in the Pro Plus line. It is built for rear ends with a GM small pattern 10/12 bolt C-clip flange and a 5×4.75/5×5.00 wheel bolt pattern, and it uses a 6-piston 6P caliper with a 13 inch rotor.
The backing plate holds the caliper and contains a one-piece park brake shoe assembly, so the parking brake is part of this kit. Rotors come pre-assembled with stainless hardware, and steel braided hoses are included. The 13 inch Pro Plus is suited to most wheels 17 inch or larger.
Key features

- Slotted, drilled, zinc-plate two-piece rotor with billet aluminum hat
- Park brake shoe assembly integrated into the backing plate
- Steel braided brake hoses, DOT approved
- Pad type FMSI D0731
Park brake maintenance
The parking brake on a rear disc kit depends on the shoe assembly, the cable and the adjustment. When the shoe sits in the backing plate, it is replaced as a unit, which keeps the geometry consistent but means the cable must be right before the new parts are used.
Park brake cables are a common reason a new kit fails to hold. Cables that stick, stretch or rust can leave a vehicle rolling or drag the shoe, so inspect the full run from the lever to the backing plate. Lubricating pivot points and checking the housings at every service helps the parking brake work as intended over time.
- Check cable housings for kinks and cracks
- Lubricate the cable ends and pivots
- Test the hold on a safe, level area
- Re-adjust after the first few days of use

Vehicle fitment
The kit is defined by the rear axle rather than by year or model. Match your rear end to a GM small pattern 10/12 bolt C-clip flange with a 5×4.75/5×5.00 bolt pattern and 5 lug wheels before choosing this kit.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The rotor and its stainless hardware arrive pre-assembled. Compare the Q110H template with the chosen wheel before the kit is mounted, because Baer cannot guarantee wheel fit for every style on the market. Installation of parking brake components should be handled by someone experienced with that hardware.
What’s included
Included: the 6P caliper system, the two-piece rotor with billet aluminum hat, the park brake shoe assembly, and stainless braided hoses with hardware.
