Overview
The Pro Plus 14-inch rear brake kit includes a 6-piston 6P caliper finished in Hugger Orange. The caliper clamps a 2-piece slotted, drilled and zinc plated rotor, and the assembly is made for rear ends with a GM small pattern 10/12 bolt axle flange and a flush mount bearing housing, also called bearing on axle (BOA).
The kit uses the D0731 pad type and the Q110P template. The rotor has a billet aluminum hat and arrives pre-assembled with NAS high grade stainless hardware. The backing plate carries a 1-piece park brake shoe assembly. The Pro Plus fits most 18 inch or larger wheels, so compare the Q110P template with the wheel before choosing it.
Key features
- 6P caliper with staggered pistons that help minimize uneven pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- 2-piece slotted, drilled, zinc plated rotor on a billet aluminum hat
- Powder coated finish, caliper manufactured in Phoenix, Az
- Steel braided hoses, DOT approved
Bedding in new pads
New pads and rotors need a short bedding procedure before they reach full stopping performance. Several moderate stops from a moderate speed transfer an even layer of friction material onto the rotor. Skipping this step can leave the pedal feeling soft or the stops uneven during the first few drives.
A 6-piston caliper spreads clamping force across a larger pad area, so pad choice affects how the brakes feel under load. Stay with the pad type matched to the kit when replacing friction material, and avoid mixing compounds on the same axle. Park brake shoes should be checked at the same service because they share the backing plate.
- Bed in pads on a clear road before towing
- Inspect caliper slide pins and boots during pad changes
- Check fluid level after any caliper service

Installation notes
Park brake cables are not included, so plan to source them separately if your parking brake needs them. Compare the Q110P template with your wheel before mounting. Brake work is safety critical, so have a qualified installer bleed the system and test the pedal before driving.
