Overview
The Baer Brakes 4302266FR is a 14.0 inch Pro Plus rear disc brake kit with a Fire Red caliper, made for GM small pattern 10/12 bolt bearing-on-axle rear ends and a 5×4.75/5×5.00 bolt pattern. The six-piston caliper works on a 14 inch two-piece rotor that carries slots, drilled holes and zinc plating.
The backing plate carries the caliper mount and houses a one-piece park brake shoe assembly. Pre-assembled rotors come with NAS high grade stainless hardware. Dust and weather seals are included, and the pads are the D0731 type. This 14 inch Pro Plus is intended for wheels 18 inch or larger; use the Q110P template to check clearance on your wheel.
Key features
- Staggered pistons help the six-piston caliper wear pads more evenly
- Pistons, abutments and noise suppression clips are stainless steel
- Seals block dust, weather and pressure
- Two-piece rotor with slotted and drilled faces, zinc plated, billet aluminum hat
- Parts machined by CNC from forged or billet aluminum
- Powder coated finish
- Braided hoses and hardware in the package
On the trail and the road
Rear disc brakes on a trail rig see a mix of hard stops, long descents and water crossings. Mud packed behind the rotor can rub the pads and cause squeal, so a quick rinse after muddy runs keeps the friction surface clean. Heat builds fast on long grades, and a larger rotor helps carry that heat away, though it cannot replace good pad choice and proper fluid.
The parking brake on a rear axle is often used on steep climbs and for holding the vehicle while winching. Check the shoe adjustment and the backing plate hardware after the first few trail outings, and re-torque any fasteners that have loosened. Replace worn shoes before the parking brake loses its hold.
- Rinse mud from the caliper and rotor after wet runs
- Inspect pads for uneven wear and glazing
- Re-check hardware after the first trail outings

Installation notes
Because the rotors come pre-assembled, the wheel check does most of the planning. Test the Q110P template on the wheel you intend to use, since Baer cannot guarantee fit with every wheel style. Parking brake hardware on a rear axle calls for a technician with disc brake experience.
