Overview
The Baer Brakes 4302342GB is a Pro Plus 14.0 inch rear brake system in Grabber Blue, sold as a complete kit for a rear axle with a GM small pattern 10/12 bolt flange and flush mount bearing housing ends. It combines a 6-piston fixed caliper with a two-piece slotted, drilled and zinc plated rotor and uses a 5×4.75/5×5.00 wheel bolt pattern with 5 lug nuts.
Baer uses the backing plate as both the caliper mount and the housing for a modern one-piece park brake shoe assembly. The 14 inch Pro Plus is listed to fit most wheels 18 inch or larger, with 18.0 inch given as the minimum wheel diameter.
Key features
- Two-piece 6-piston caliper with stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- Two-piece slotted, drilled, zinc plated rotor with billet aluminum hat, pre-assembled with NAS high grade stainless hardware
- CNC machined body from US sourced forged or billet aluminum with a powder coated finish
- Stainless steel braided hoses and hardware included
- Pad type D0731 (FMSI)
Pads, rotors and wear
Pads and rotors wear together, so inspecting one without the other can miss a problem. Pad material should stay even across the friction face, and the rotor should be free of deep grooves or heat spots. Uneven wear often points to a sticking caliper slide, a damaged hose or an unbalanced load on the brakes.
The staggered piston layout on this caliper is meant to spread pad pressure more evenly, but it does not replace routine inspection. Plan to check pad thickness at each tire rotation, and replace pads and rotor as a matched pair when either is worn past its limit. A cracked or heavily scored rotor should not be reused.
- Replace pads and rotor as a matched pair when worn
- Check caliper slides for smooth movement
- Watch for pulsation under braking
- Keep the wheel bearing and hub in good condition

Vehicle fitment
Its fit depends on the rear axle flange, a GM small pattern 10/12 bolt with flush mount bearing housing ends, and the 5×4.75/5×5.00 wheel bolt pattern. Compare those dimensions with your axle and wheels first.
Confirm your vehicle’s year, model and trim before ordering. Baer does not guarantee fit into every wheel style, so use the Q110P template to compare the wheel you plan to run.
Installation notes
The rotors come pre-assembled with stainless hardware, and the park brake shoes sit inside the backing plate, so the rear end’s flange and bearing housing should be measured before mounting. Hydraulic brake work should be finished by a qualified technician who bleeds the lines and tests the system.
What’s included
Brake kit with a 6-piston caliper, a two-piece 14.0 inch rotor with pre-assembled NAS high grade stainless hardware, stainless braided hoses and hardware, and a one-piece park brake shoe assembly.
