Overview
The Baer Brakes 4302342MG is a Pro Plus 14-inch rear brake system built around a 6-piston 6P caliper in Monster Green. It clamps a 2-piece slotted, drilled and zinc plated rotor and is made for rear ends with a GM small pattern 10/12 bolt axle flange and flush mount bearing housing, often called bearing on axle (BOA).
The kit uses the D0731 pad type and the Q110P template. Its rotor arrives pre-assembled with NAS high grade stainless hardware, and the backing plate holds a modern 1-piece park brake shoe assembly. Baer lists the Pro Plus as fitting most 18 inch or larger wheels and recommends checking the template against the wheel you plan to run.

Vehicle fitment
No vehicle fitment is listed for this kit. Based on the description, it is a rear brake system for an axle with a GM small pattern 10/12 bolt flange, flush mount bearing housing and 5×4.75/5×5.00 bolt pattern. Verify the axle and wheel pattern before ordering.
Confirm your vehicle’s year, model and trim before ordering. Check the manufacturer’s specifications for the rear axle type.
Installation notes
Because the rotor comes pre-assembled with its hardware, mounting is simpler, but the Q110P template should still be compared with the wheel before the kit goes on. Park brake cables are not included and must be sourced separately. Brake work is safety critical, so have a qualified installer bleed the system and test the pedal before driving.
