Overview
The Baer Brakes Pro Plus 14.0 inch rear disc brake kit in red, part number 4302342R, is made for rear axles with a GM small pattern 10/12 bolt flange and a flush mount bearing on the axle. Its 6P six-piston caliper clamps a 14.0 inch two-piece, slotted and drilled rotor, and the kit is intended for wheels 18.0 inch in diameter or larger.
The backing plate doubles as the caliper mount and houses a one-piece park brake shoe, so park brake function comes with the kit. The D0731 pad type fits this system. Rotors arrive pre-assembled with NAS high grade stainless hardware, and the caliper finish is red.
Key features
- Two-piece 14.0 inch rotor with a zinc plated, slotted and drilled face and a billet aluminum hat.
- Six-piston 6P caliper machined from forged or billet aluminum.
- Stainless steel pistons, abutments and noise suppression clips.
- Pistons staggered to reduce uneven pad wear.
- Dual seals protect against dust, weather and pressure.
- Stainless braided hoses and hardware come with the kit.
- Red powder coated finish.
Choosing the right setup
Rear brake upgrades are easiest to plan around the axle first. The flush mount housing and bearing on axle set the mounting points, so the caliper and rotor must line up with those before anything else. Wheel choice comes next. A wheel that clears the caliper with room to spare avoids rubbing through steering and suspension travel, and a change in offset can shift that clearance.
Park brake function is the other factor to plan for. Because the shoe assembly sits in the backing plate, cables and adjustment hardware need to be ready before the wheels go back on. Brake hoses should be routed clear of the suspension and driveline through full travel. Bleed the fluid after installation and check the pedal before driving.
- Confirm wheel clearance around the caliper body
- Route braided hoses clear of moving parts
- Use fresh brake fluid at installation
- Bed in new pads gradually before heavy use

Vehicle fitment
This kit has no listed vehicles. Its fit is defined by the rear axle: a GM small pattern 10/12 bolt flange with a flush mount bearing on the axle, a 5×4.75 and 5×5.00 wheel bolt circle, and wheels 18.0 inch or larger. Those are the points to check against your axle.
No specific model or model year is named for this part number, so axle type alone does not confirm a match. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Stainless braided hoses and hardware are included, and the rotors are already pre-assembled with stainless fasteners. Park brake cables are not supplied, so plan to obtain them separately if the park brake will be used. Baer advises checking the Q110P template against your wheel, because the company cannot guarantee fit with every wheel style.
What’s included
The package covers the two-piece 14.0 inch rotors with pre-assembled stainless hardware, the 6P caliper, the backing plate with its one-piece park brake shoe assembly, and stainless braided hoses with hardware.
Not included: park brake cables, a front rotor and lug nuts.
