Overview
Baer Brakes Extreme Plus rear brake kit, part number 4302252FR, comes in Fire Red and is made for rear axles with a GM 10/12 bolt C-Clip flange and 5×4.75/5×5.00 wheel bolts. Its 1-piece monoblock caliper carries six pistons and clamps a 14 inch two-piece slotted, drilled, zinc plated rotor.
Fire Red is the caliper color. The backing plate serves as the caliper mount and houses a one-piece park brake shoe assembly. The kit uses D1247 pads, a floating caliper, a rotor thickness of 1.25 and a minimum wheel diameter of 18.0 inch. It fits most 18 inch or larger wheels.
Key features
- 1-piece monoblock, 6-piston, 6S caliper manufactured in Phoenix, Arizona
- Caliper body CNC machined from 2618 aluminum forging, powder coated
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons that minimize uneven pad wear
- Dual dust/weather and pressure seals
- Two-piece slotted, drilled, zinc-plated rotor, pre-assembled with NAS high grade stainless hardware
Parking brake and rear hub
A one-piece park brake shoe assembly like the one in this kit sits inside the backing plate, so the parking brake shares hardware with the rear service brake. Adjustment and wear on the shoes affect how well the handbrake holds. A parking brake that needs many extra clicks before it grips is often out of adjustment or has worn linings.
Working on the parking brake means the rear wheels will be off, so plan the job around the full set of brake parts. Check the shoe lining, springs and adjuster movement, and confirm the cable pulls freely before setting final tension. Fresh brake fluid and clean mating surfaces help the system hold consistent pressure.

- Adjuster movement
- Cable pull and routing

Vehicle fitment
The application is set by the rear axle flange, GM 10/12 bolt C-Clip small car pattern, on a 5×4.75/5×5.00 bolt pattern. Compare these figures with your rear axle before buying.
Confirm your vehicle’s year, model and trim before ordering. Compare the N110P template with your wheel of choice to confirm clearance.
Installation notes
Check wheel clearance with the N110P template before installing, because wheel style varies. The park brake shoe assembly is part of the backing plate, and the kit does not include park brake cables. Installation should be done by a qualified brake technician.
What’s included
The kit includes the 1-piece monoblock caliper, two-piece rotors pre-assembled with stainless hardware, the backing plate with its park brake shoe assembly, and stainless braided hoses with hardware.
