Overview
The Fire Red Extreme rear brake kit uses a 14 inch rotor and 6-piston monoblock caliper. It fits Chevrolet and GMC 1500-series trucks and SUVs in the years shown below, and it is designed for trucks that already have factory rear disc brakes and a manual park brake.
The rotor is a vented, one-piece design with slots, drill holes and zinc plating, mounted to a billet aluminum hat. The caliper is CNC machined from 2618 aluminum forging in Phoenix, Arizona, and its staggered pistons are designed to reduce uneven pad wear. The kit uses the D1247 pad type. Check the wheel fit against template N228P before buying wheels.
Key features
- 1-piece monoblock, 6-piston, 6S caliper in Fire Red
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons to minimize uneven pad wear
- Dual seals against dust, weather and pressure
- 14.0 inch one-piece slotted, drilled, zinc-plated rotor
- Billet aluminum rotor hat
- Brackets and hardware included
Keeping the rear brakes in shape
Rear brake hardware sees less heat than the front, but it still wears, and a fresh kit is a good time to set a routine. Pads and rotors should be checked for uneven wear, heat checks and a raised lip on the rotor edge. Once the new parts are installed, adjust and test the factory park brake so it holds the truck on a slope without dragging.
Fire Red powder coat is a visible finish, so keep the caliper clean of road grime and brake dust with a gentle wash rather than harsh solvents. Check the boots and hoses for cracks each time the wheels come off. Matching front and rear pad compounds helps the truck brake evenly, and a clean rotor surface helps new pads seat well.
- Check rotor thickness at each pad change against the service limit
- Look for pedal pulsation, which can signal rotor runout
- Inspect the factory hoses for swelling or cracking
- Re-torque lug nuts after the first few drives

Installation notes
The factory hoses and park brake are kept, and brackets plus hardware come with the kit. Template N228P is the reference for wheel clearance, since the kit targets 18.0 inch wheels and larger. Verify firm pedal travel in a parking area before driving on public roads.
What’s included
The kit includes the 6S monoblock caliper, the 14.0 inch one-piece rotor with billet aluminum hat, and the brackets and hardware.
Not included: park brake, which stays with the factory setup.
