Overview
The Grabber Blue Extreme Plus kit, Baer part number 4302252GB, combines a 1-piece monoblock 6-piston, 6S caliper with a 14 inch two-piece rotor. It is aimed at rear axles that use the GM 10/12 bolt C-Clip small car pattern flange and a 5×4.75/5×5.00 wheel bolt pattern. Grabber Blue is the caliper finish.
Baer machines the caliper from 2618 aluminum forging in Phoenix, Arizona, and uses stainless pistons with staggered placement to reduce uneven pad wear. Dual seals guard against dust, weather and pressure. The kit ships with the rotor assembly, caliper, backing plate, stainless braided hoses and stainless hardware. It fits most 18 inch or larger wheels.
Key features
- 1-piece monoblock, 6-piston, 6S caliper
- CNC machined 2618 aluminum forging with powder coated finish
- Stainless steel pistons, abutments and noise suppression clips
- Dual dust/weather and pressure seals
- Two-piece slotted, drilled, zinc-plated rotor with billet aluminum hat
- Backing plate houses a one-piece park brake shoe assembly
Pads, rotors and wear
Brake pads are the wear item in any disc kit, and their friction material sets how the rotor wears. Harder compounds last longer but can be noisier and less grippy when cold, while softer compounds bite earlier and create more dust. Matching the pad compound to the way the vehicle is driven usually matters more than chasing a particular feel.
Rotors wear through heat cycling and friction, so check the surface for scoring, hot spots and thickness loss at each pad change. Slotted and drilled rotors help clear gas and debris but can crack under severe heat if the setup is overworked. Keep the caliper slides clean and lubricated so the pads release evenly and do not drag.

Vehicle fitment
The application is the axle: a GM 10/12 bolt C-Clip small car pattern flange on a 5×4.75/5×5.00 bolt pattern. Match the axle to your vehicle before ordering.
Confirm your vehicle’s year, model and trim before ordering. Check wheel clearance against the N110P template, since wheel style varies.
Installation notes
Compare the rotor against your wheel using the N110P template first. Park brake cables are not included, so check cable length and routing against the park brake assembly before starting. Have a qualified brake technician do the work.
What’s included
The kit includes the 1-piece monoblock caliper, the two-piece rotors pre-assembled with NAS high grade stainless hardware, the backing plate with its park brake shoe assembly, and stainless braided hoses with hardware.
Not included: park brake cables.
