Overview
Fire Red Baer Brakes part 4302342FR is a Pro Plus 14.0 inch rear disc brake package built around a 6-piston fixed caliper, made for rear axles with a GM small pattern 10/12 bolt flange and flush mount bearing housing ends. The wheel bolt pattern is 5×4.75/5×5.00 with 5 lugs.
The caliper is manufactured in Phoenix, Az and CNC machined from US sourced forged or billet aluminum. The backing plate serves as the caliper bracket and holds a modern one-piece park brake shoe assembly. The 14 inch Pro Plus fits most wheels 18 inch or larger.
Key features
- Staggered pistons designed to reduce uneven pad wear
- Two-piece 6-piston caliper with stainless steel pistons, abutments and noise suppression clips
- Dual dust, weather and pressure seals
- Slotted, drilled, zinc plated two-piece rotor on a billet aluminum hat
- Rotors pre-assembled with NAS high grade stainless hardware
- Powder coated finish in Fire Red
- Stainless steel braided hoses and hardware included
Caliper and pad maintenance
A fixed multi-piston caliper relies on clean pistons, intact seals and free-moving pads. Dust and road grime can build up around the piston bores and in the pad pockets, so periodic cleaning keeps the pads seating squarely. Look for fluid weeping around the piston seals, since a leaking seal lowers hydraulic pressure at the pads.
Heat is the main enemy of brake components. Repeated hard stops, long downhill runs or towing can glaze pads and discolor rotors, so allow the system to cool between heavy stops. Powder coated calipers should be cleaned with water and mild soap, avoiding harsh solvents that can dull the finish.
- Clean pad pockets during pad changes
- Check piston seals for fluid weeping
- Let brakes cool after repeated hard stops
- Inspect the powder coat for chips

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 rear end and wheels before installing.
Confirm your vehicle’s year, model and trim before ordering. Because the wheel market is so varied, Baer cannot promise a fit on every wheel, and the Q110P template is the check to run.
Installation notes
Pre-assembled rotors arrive with NAS stainless hardware already fitted, so clearance comes first: compare the Q110P template against the intended wheel before the kit is mounted. Have a shop experienced with hydraulic plumbing install the hoses and road test the vehicle afterward.
What’s included
A 6-piston Fire Red caliper, a two-piece 14.0 inch slotted, drilled, zinc plated rotor, stainless braided hoses and hardware, and a one-piece park brake shoe assembly.
