Overview
The Baer Brakes 4302266MG is a Pro Plus 14.0 inch rear brake kit in Monster Green. It is designed for rear axles with a GM small pattern 10/12 bolt bearing-on-axle flange and a 5×4.75/5×5.00 bolt pattern, and it pairs a six-piston fixed caliper with a 14 inch two-piece rotor.
A billet aluminum hat carries the rotor, which comes pre-assembled with NAS high grade stainless hardware. The backing plate is the caliper mount and also holds a one-piece park brake shoe assembly. Dust and weather seals are fitted and the pads are the D0731 type. This 14 inch Pro Plus is intended for wheels 18 inch or larger, and the Q110P template is the check to run before mounting.
Key features
- Staggered pistons on the six-piston caliper help limit uneven pad wear
- Pistons, abutments and noise clips are all stainless steel
- Seals guard against dust, weather and pressure
- Slotted, drilled, zinc plated two-piece rotor with a billet aluminum hat
- Caliper body machined on CNC equipment from forged or billet aluminum
- Powder coat finish
- Braided hoses with hardware come in the kit
Choosing the right setup
Moving to a larger rotor often changes how the brake system feels at the pedal. A bigger rotor gives the pads more leverage and more swept area, which helps with repeat stops, but it also asks more of the caliper, hoses and fluid. Before ordering, confirm the wheel clearance around the caliper and the offset of the wheel, since both decide whether the setup seats correctly.
Brake fluid is worth changing when a larger brake system goes in, because old fluid absorbs moisture and loses boiling strength under repeated hard stops. Pads should match the caliper and rotor design, and the FMSI pad number is the reference point for matching them. Keep the stainless hardware clean and lightly greased so the rotor can be removed for future service.
- Check wheel clearance with the caliper before mounting
- Replace brake fluid with the new system installed
- Confirm the master cylinder can handle the pedal travel

Vehicle fitment
This kit is built for GM small pattern 10/12 bolt bearing-on-axle rear ends, so compare the flange and wheel bolt pattern on your axle with the specifications above.
Installation notes
The rotors come pre-assembled, so the wheel template check is the main fitting step here. Use the Q110P template against the wheel you intend to run, because Baer does not guarantee fit across every wheel style. Parking brake work on a rear axle is best left to a technician who knows this hardware.
What’s included
The kit contains the six-piston Monster Green caliper, the 14 inch two-piece rotors with stainless hardware, the backing plate with its park brake shoe assembly, and braided hoses with hardware.
Not included: park brake cables.
