Overview
The Baer Brakes Extreme Plus Brake System Front, part number 4301571B, is a black front disc brake kit for 2WD 1/2 Ton Chevrolet and GMC C10 trucks. Vehicles on the manufacturer list span 1960-1986 Chevrolet C10 and C10 Suburban, 1960-1966 and 1987-1989 Chevrolet Suburban, 1960-1966 GMC 3000, 1975-1978 GMC C15, 1967-1974 GMC C15/C1500 and 1979-1986 GMC C1500.
At the center of the kit is a one-piece monoblock six-piston caliper, the 6S model, paired with a 14 inch two-piece slotted, drilled and zinc plated rotor. Baer designs the rotor to fit most wheels of 18 inch diameter or larger, and the calipers are manufactured in Phoenix, Arizona.
Key features
- One-piece monoblock six-piston 6S caliper in black
- Caliper machined from U.S. sourced 2618 aluminum forging
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to reduce uneven pad wear
- Dual seals for dust, weather and pressure
- Two-piece slotted, drilled, zinc plated 14 inch rotor with a billet aluminum hat
- Rotors arrive pre-assembled with NAS high grade stainless hardware
Care and pre-install checks
A black caliper finish is mostly a visual choice, but the finish still deserves care. Powder coating can chip where a wrench or tire iron rubs, so keep a small touch-up supply on hand and clean road salt and brake dust off the caliper body with mild soap and water. Dirt trapped behind the caliper can also make the piston move unevenly over time, so clean the area during every pad change. Avoid harsh solvents on the seals and pad areas.
Gear that touches the brakes should be matched. Pads made to the correct friction spec keep braking smooth, and a mismatched pad can squeal or fade under load. Inspect the brake hose at every service for cracks or bulges, and replace any hose that looks swollen. Old brake fluid that has darkened should be flushed rather than topped off, since it can carry moisture into the caliper. Make sure the parking brake cable and linkage still move freely after the front job.
Keep a service log with dates for pad changes, fluid changes and torque checks. A written record helps spot a pattern, such as one front wheel wearing pads faster, which can point to a sticking caliper slide or a bent backing plate.

Installation notes
Spindles are not part of this kit, so a truck needs either Wilwood C10 Aluminum Modular Pro spindles or Cpp X10 spindles. Both spindle options are supported. Wheel fit varies by style, so compare the N117P template with the wheel before installing.
What’s included
Rotors pre-assembled with NAS high grade stainless hardware, the 6S one-piece monoblock caliper, mounting brackets, and stainless braided hoses with hardware.
Not included: Spindles. Wilwood C10 Aluminum Modular Pro or Cpp X10 spindles are required and are sold separately from this kit.
