Overview
The Baer Brakes Extreme Plus 14 inch rear brake kit, part number 4302252MG, is finished in Monster Green and built for GM 10/12 bolt C-Clip (small car pattern) rear axles on 5×4.75/5×5.00 bolt patterns. Its one-piece monoblock 6-piston, 6S caliper clamps a 14 inch two-piece slotted, drilled and zinc plated rotor.
Each caliper body is CNC machined from 2618 aluminum forging and paired with stainless pistons and dual seals. The kit uses a floating caliper design and the D1247 pad type, and the rotor is 1.25 thick. The Extreme Plus fits most 18 inch or larger wheels, with a minimum wheel diameter of 18.0 inch.
Key features
- One-piece monoblock, 6-piston, 6S caliper, manufactured in Phoenix, Arizona
- CNC machined from 2618 aluminum forging with a powder coated finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to minimize uneven pad wear
- Dual dust/weather and pressure seals
- Two-piece slotted, drilled, zinc-plated rotor with billet aluminum hat, pre-assembled with NAS high grade stainless hardware
Choosing the right setup
Rear C-clip axles hold the wheel bearing and axle shaft retention in a single assembly, so a brake upgrade is tied to how that axle is built. A monoblock caliper is a single casting that clamps the rotor from one body, which keeps the piston area steady under heavy braking. Stiffer calipers are often paired with a matching pad compound, since the pad choice governs heat, noise and dust as much as the caliper does.
When sizing up a rotor, check the wheel bore and hub face against the rotor hat before mounting, and make sure the caliper still clears the spokes. Braided hoses are often replaced along with the caliper because they resist expansion under pressure. Inspect the park brake shoes and adjuster during the same job, since the parking function shares the backing plate.

Vehicle fitment
The application is set by the axle flange: GM 10/12 bolt C-Clip in the small car pattern. The kit suits that bearing-on-axle layout.
Confirm your vehicle’s year, model and trim before ordering. Compare the N110P template with your wheel to confirm clearance.
Installation notes
Use the N110P template to check wheel clearance on the 14 inch rotor before assembly, since wheel style can change clearance. Park brake cables are not in the kit, so confirm existing cables match the park brake assembly. Brake work should be done by a qualified technician.
What’s included
The kit includes the one-piece monoblock caliper, two-piece rotors pre-assembled with stainless hardware, the backing plate with the park brake shoe assembly, and stainless braided hoses with hardware.
Not included: park brake cables.
