Overview
The Baer Brakes 4302266HO is a Pro Plus 14.0 inch rear disc brake kit with a Hugger Orange caliper, sold for GM small pattern 10/12 bolt bearing-on-axle rear ends with a 5×4.75/5×5.00 bolt pattern. Each kit runs a six-piston fixed caliper over a 14 inch two-piece rotor that is slotted, drilled and zinc plated.
Rotors come pre-assembled with NAS high grade stainless hardware. The backing plate serves as the caliper mount and houses a one-piece park brake shoe assembly, which keeps the parking brake inside the rear unit. The caliper has dust and weather seals and uses the D0731 pad type. The 14 inch Pro Plus is made for wheels 18 inch or larger, and the wheel should be checked against the Q110P template before mounting.
Key features
- Six pistons arranged in a staggered layout, which Baer says helps even out pad wear
- Abutments are stainless, joined by stainless noise suppression clips
- Double seal design guards against dust, weather and pressure
- Rotor is two pieces, slotted, drilled, zinc-plated, with a billet hat
- Forged or billet aluminum parts are CNC machined in the US
- Powder coated finish
- Braided hoses and hardware are supplied with the kit
Park brake and rear unit service
On many rear ends the parking brake is a separate cable system, but this kit houses a one-piece shoe assembly inside the backing plate. Service means checking the shoes for wear and the adjuster for smooth travel, and keeping grease away from the friction surfaces. Hub bearings and seals are worth inspecting at the same time, since they share the same work area.
The powder coat finish scratches easily, and exposed metal on the caliper can collect moisture. Touch up small chips and keep the caliper clean of road salt. When pads are rotated or replaced, check that the caliper slides move freely so the pads wear evenly.
- Inspect the backing plate for cracks after hard impacts
- Keep wheel studs and lug nuts clean and free of corrosion
- Replace worn brake hoses before they swell or crack

Vehicle fitment
This Hugger Orange system is built for rear axles with a GM small pattern 10/12 bolt flange and a 5×4.75/5×5.00 wheel bolt pattern. Match those two details on your axle before choosing it.
Before ordering, match the year, model and trim to your truck or SUV. Axles with other flange patterns fall outside this GM small pattern design, so measure the flange and bolt pattern first.
Installation notes
Because the rotors arrive pre-assembled, the wheel check is the main installation step. Set the Q110P template against the wheel you plan to run before mounting. Rear disc and park brake work is best handled by a technician comfortable with this hardware.
