Overview
The Baer Brakes 4301571GB is a front Extreme Plus brake kit in Grabber Blue for 2WD half-ton Chevy C10 and GMC C15 trucks from 1960 to 1986. Its core is a 14-inch rotor gripped by a one-piece monoblock 6S caliper with six pistons and stainless steel pistons.
Trucks equipped with Wilwood C10 Aluminum Modular Pro spindles or Cpp X10 spindles are the intended match, and those spindles are not part of the kit. Rotors come assembled with NAS high-grade stainless hardware, and braided stainless hoses plus mounting brackets round out the set.
Key features
- Monoblock 6S caliper with six pistons in a fixed design
- Caliper machined from 2618 aluminum forging sourced in the United States
- Powder-coated body with stainless pistons and noise suppression clips
- Staggered piston arrangement to even out pad wear
- Dual dust, weather and pressure seals
- Slotted, drilled, zinc-plated two-piece rotor with billet aluminum hat
Pads, wheels and fluid
Friction material is the part of a front brake job most people revisit first. A six-piston caliper squeezes the pad harder than a stock single-piston unit, so pads wear through faster when a truck is used for heavy towing or steep descents. Check pad thickness at each tire rotation and replace them once the lining reaches the wear indicator or gets close to the backing plate.
Wheel choice also deserves attention. Look for clearance between the barrel and the caliper body at full steering lock, and make sure the lug nuts seat cleanly against the rotor hat. Brake fluid is worth replacing when the new lines go in, since older fluid absorbs moisture and loses boiling point, which matters more once the system works harder.

Vehicle fitment
The fitment covers 1979–1986 GMC C1500 and 1967–1974 GMC C15/C1500 trucks, 1975–1978 GMC C15, 1960–1966 GMC 3000, 1960–1986 Chevrolet C10, 1967–1986 Chevrolet C10 Suburban and the 1960–1966 plus 1987–1989 Chevrolet Suburban.
Trucks outside those years, and four-wheel-drive trucks (the kit is 2WD), are not covered by the list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Plan on the truck already having Cpp X10 or Wilwood C10 Modular Pro spindles, because the kit leaves them out. Run the N117P template on the wheel you intend to use; the 14-inch rotor fits most wheels 18 inches or larger.
What’s included
Included are the 6S caliper, two-piece rotors pre-assembled with stainless hardware, mounting brackets, and stainless braided hoses with their hardware.
Not included: spindles.
