Overview
The Baer Brakes Pro Plus 14.0 Inch brake system, part number 4302266CY, is a rear disc brake kit for GM small pattern 10/12 bolt axles with non-flush mount housing ends and a 5×4.75/5×5.00 bolt pattern. It combines a 6-piston, 6P caliper in Comp Yellow with a 14 inch two-piece slotted, drilled and zinc plated rotor.
Baer’s backing plate serves as the caliper mount and houses a one-piece park brake shoe assembly, so the parking brake comes built into the kit. The kit is set up around the D0731 pad type. The 14 inch Pro Plus fits most 18 inch or larger wheels, with a minimum wheel diameter of 18.0 inch.
Key features
- 6-piston, 6P caliper, CNC machined from US-sourced forged or billet aluminum and manufactured in Phoenix, Arizona
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to reduce uneven pad wear
- Dual dust/weather and pressure seals
- Two-piece slotted, drilled, zinc-plated rotor with billet aluminum hat
- Powder coated finish
- Rotors pre-assembled with NAS high grade stainless hardware, plus stainless braided hoses
Before you buy
A rear disc kit replaces the braking hardware at the axle, so the first check is the axle itself. Measure the flange and bearing layout, count the lugs, and compare the wheel bolt pattern before looking at anything else. A rotor that clears the caliper still needs room for the wheel’s backspacing, since offset changes can bring the tire into contact with the caliper body even when the rotor fits.
Kits with a park brake shoe inside the backing plate tie the parking function to the rear hub, so the shoes, adjuster and cables should be inspected together. Brake fluid and braided hoses are commonly renewed when the system is opened up, and pads should be matched to the rotor when the caliper is changed. Bedding in new pads gradually helps them lay an even layer onto the rotor.

Vehicle fitment
The axle flange is GM small pattern 10/12 bolt bearing on axle, and it is used on Buick, Oldsmobile and Pontiac applications.
Confirm your vehicle’s year, model and trim before ordering. Measure your axle flange and wheel clearance, and check the Q110P template against your wheel of choice.
Installation notes
Baer’s Q110P template is the reference for checking wheel clearance against the 14 inch rotor before the kit is mounted. Because the park brake shoe assembly sits inside the backing plate, the parking brake is installed with the rest of the kit. Brake work should be done by a qualified technician with the proper tools.
What’s included
The kit includes the 6P two-piece rotor assembly with its caliper, the Baer backing plate with the one-piece park brake shoe assembly, stainless braided hoses, and the NAS high grade stainless hardware.
Not included: park brake cables.
