Overview
Part 4302252HO is the Baer Brakes Extreme Plus rear brake kit in Hugger Orange, designed for GM 10/12 bolt C-Clip small car pattern rear axles with a 5×4.75/5×5.00 bolt pattern. The kit uses a 1-piece monoblock 6-piston, 6S caliper that clamps a 14 inch two-piece slotted, drilled and zinc plated rotor.
The rotor is vented and has a thickness of 1.25. The backing plate holds the caliper mount and a one-piece park brake shoe assembly, so the parking brake hardware travels with the kit. D1247 is the FMSI pad type. The Extreme Plus fits most 18 inch or larger wheels, with a minimum wheel diameter of 18.0 inch.
Key features
- 1-piece monoblock, 6-piston, 6S caliper made in Phoenix, Arizona
- Caliper body CNC machined from 2618 aluminum forging, powder coated
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons to reduce uneven pad wear
- Dual seals for dust, weather and pressure
- Rotors pre-assembled with NAS high grade stainless hardware
Wheel fit and clearance
Wheel fit decides whether a large rotor works in practice. Backspacing, offset and the inside clearance of the wheel barrel all determine whether the caliper body and spokes have room. Two wheels with the same diameter can clear differently, so a template check is more reliable than the wheel label alone.
Vehicles that tow, climb steep grades or make repeated trail descents put more heat into the rear brakes than daily driving does. Ventilated rotors shed heat faster, but pad choice and fluid condition still matter. Check rotor runout and surface wear whenever the wheel is off, and replace any rotor that has lost meaningful thickness or shows deep grooves.
- Backspacing and offset
- Spoke and barrel clearance
- Heat load from towing or long descents
- Rotor surface after heavy use

Vehicle fitment
Its fit is set by the rear axle flange, a GM 10/12 bolt C-Clip small car pattern with a 5×4.75/5×5.00 wheel bolt pattern. Compare those measurements with your axle before buying.
Confirm your vehicle’s year, model and trim before ordering. Wheel style affects clearance, so compare your wheel to the N110P template.
Installation notes
Set the N110P template against your wheel of choice before mounting, because wheel style determines whether the 14 inch rotor clears. The park brake shoe assembly is part of the backing plate. Have a qualified technician handle the installation.
What’s included
The kit includes the monoblock caliper, the two-piece vented rotor pre-assembled with stainless hardware, the backing plate with its park brake shoe assembly, and stainless braided hoses with hardware.
Not included: park brake cables.
