Overview
The Baer Brakes Extreme Plus Brake System Front, part number 4301571CY, is a Comp Yellow front disc brake kit for 2WD 1/2 Ton Chevrolet and GMC C10 trucks. The manufacturer list covers 1960-1986 Chevrolet C10 models, 1967-1986 Chevrolet 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.
The kit centers on a one-piece monoblock six-piston caliper, the 6S model, mounted to a 14 inch two-piece slotted, drilled and zinc plated rotor. The 14 inch rotor is meant for wheels 18 inch or larger, and the caliper is manufactured in Phoenix, Arizona.
Key features
- One-piece monoblock six-piston 6S caliper with a powder coated Comp Yellow finish
- Caliper machined from U.S. sourced 2618 aluminum forging
- Stainless steel pistons, abutments and noise suppression clips
- Staggered piston layout intended to limit uneven pad wear
- Dual seals guarding against 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
Choosing a setup
Before buying brake parts for an older Chevy or GMC pickup, it helps to confirm what is already under the truck. Spindle type, wheel offset and steering geometry all affect how a caliper sits in relation to the wheel. Taking measurements with the old parts still on the truck makes it easier to see whether a larger rotor will clear the spokes or lip of the wheel.
Brake lines, the master cylinder and the proportioning valve often need attention once the front system is upgraded. A stronger front setup can change the balance of braking, so a mechanic may suggest inspecting the rear brakes at the same time. Keep the old parts until the new ones are checked, and plan the job for a weekend with the right torque wrench on hand.
