Overview
Fire Red is the finish on Baer Brakes part 4302341FR, an Extreme Plus rear brake system kit for rear axles with a GM small pattern 10/12 bolt bearing-on-axle flange and flush mount bearing housing ends. The kit pairs a 1-piece Monoblock 6-piston 6S caliper with a 14-inch two-piece slotted, drilled, zinc-plated rotor for 5×4.75/5×5.00 inch bolt patterns.
A backing plate serves as the caliper carrier and houses a 1-piece park brake shoe assembly. Stainless braided hoses and stainless hardware are supplied, and the rotors arrive assembled with NAS high-grade stainless hardware. The 14-inch rotor is sized for wheels 18 inches or larger, and the wheel design still needs checking against template N110P.
Key features
- Monoblock 6-piston 6S caliper, 1 piece, made in Phoenix, AZ
- CNC machined 2618 aluminum forging, USA origin
- Fire Red powder coat finish
- Stainless pistons, abutments and noise suppression clips
- Staggered piston layout to limit uneven pad wear
- Dual seals guard against dust, weather and pressure
- Slotted, drilled, zinc-plated 2-piece rotor with billet aluminum hat
- Park brake shoe assembly built into the backing plate
Bedding in new brakes
New pads and rotors need a short bedding procedure so the friction layer transfers evenly. Make several moderate stops from speed on a clear road, then let the brakes cool without holding the pedal down. Avoid hard stops or long downhill braking until the pads are bedded in, since heat can glaze the surface. Pad compound also matters, since some mixes need more heat than others to settle.
Slotted and drilled rotors clear dust and gas quickly, but they also shed material early in the break-in period. Expect a light dust layer for the first stretch of driving. A pulsing pedal, squeal or uneven pull after bedding is a sign to re-inspect the caliper slide, pad seating and rotor face.
- Moderate stops from speed on a clear road
- Let brakes cool between cycles
- Recheck pad seating if noise develops

Vehicle fitment
This kit is designed for rear axles with a GM small pattern 10/12 bolt rear flange and flush mount bearing, with a 5×4.75/5×5.00 wheel bolt pattern. Compare those axle dimensions with your vehicle before ordering.
Use template N110P to test wheel clearance, since wheel designs vary and Baer cannot promise fit for every one. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Rotors are supplied assembled, so there is no separate rotor build to plan for. The backing plate holds the park brake shoe assembly and also acts as the caliper carrier. Park brake cables are not part of the package, so budget for them if your setup needs them. Rear brake work calls for a qualified installer who bleeds the hydraulic system before the vehicle is driven.
What’s included
The package holds the 6S Monoblock caliper with six pistons, two-piece rotors pre-assembled with NAS stainless hardware, the backing plate with its 1-piece park brake shoe assembly, and stainless braided hoses with hardware.
Not included: park brake cables.
