Overview
The Baer Brakes 4302248FR is a Pro Plus rear brake kit in Fire Red, made for rear ends with a GM small pattern 10/12 bolt C-clip axle flange. The system uses a 6-piston 6P caliper and a 13 inch two-piece rotor on a 5×4.75/5×5.00 wheel bolt pattern.
The backing plate acts as the caliper mount and houses a one-piece park brake shoe assembly. Stainless braided hoses and hardware come with the kit, and the rotors arrive pre-assembled. The 13 inch Pro Plus is intended for wheels 17 inch or larger.
Key features
- 6-piston caliper with stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- Powder coated finish in Fire Red on CNC machined parts of US sourced forged or billet aluminum
- Two-piece slotted, drilled, zinc plated rotor with billet aluminum hat
- Park brake shoe assembly built into the backing plate
- Steel braided hoses, DOT approved
- Disc brake pads use FMSI number D0731
Hoses, fluid and care
Steel braided hoses hold their shape better than rubber under pedal pressure, which helps keep the pedal firm. Their outer braid can chafe against suspension components, so route them clear of springs, shocks and sharp edges, and check the fittings for seepage after each installation.
Whenever the hydraulic system is opened, the brake fluid should be replaced rather than topped off. Old fluid absorbs moisture and can reduce resistance to boiling during hard stops. Bleeding the new caliper and hoses in the correct sequence removes trapped air that would soften the pedal.
- Inspect hose fittings for seepage after installation
- Keep hoses clear of moving suspension parts
- Replace the fluid rather than topping it off
- Check the pads and rotor surface at the first service

Vehicle fitment
Fitment is defined by the rear axle: a GM small pattern 10/12 bolt C-clip rear end with a 5×4.75/5×5.00 bolt pattern and 5 lug wheels.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Use the Q110H template to check the Fire Red kit against the wheel you intend to run, since Baer does not guarantee wheel fit for every wheel style. The rotors come pre-assembled with stainless hardware, and the park brake shoe assembly is part of the backing plate. Work on brake components should be done by an experienced installer.
What’s included
Included: the 6P caliper system in Fire Red, two-piece rotors with billet aluminum hats, the park brake shoe assembly, and stainless braided hoses with hardware.
Not included: Park brake cables.
