Overview
The Baer Brakes 4301570CY is a Pro Plus front brake system finished in Comp Yellow, built for 1960–1987 Chevy and GMC two-wheel-drive half-ton C10 pickups. Its six-piston two-piece caliper clamps a 14-inch two-piece rotor, and the kit works with Wilwood C10 Aluminum Modular Pro or Cpp X10 spindles, which must be supplied separately.
Owners running larger rims on a classic C10 are the intended buyers, since the kit calls for 18-inch or larger wheels. Wheel fit depends on the wheel style and maker, so a template check should come before the final build.
Key features
- Six-piston two-piece caliper built with stainless pistons and abutments.
- Pistons are staggered to even out pad wear across the friction surface.
- Dual seals protect the hydraulics from dust, weather and pressure loss.
- Slotted, drilled and zinc-plated two-piece 14-inch rotor on a billet aluminum hat.
- Rotor assemblies come pre-built with NAS high grade stainless hardware.
- Comp Yellow powder coat covers the CNC machined aluminum caliper.
Planning a front brake swap
A front brake conversion touches more than the caliper. Steering geometry, hub bearings and the wheel itself all have to work together, so plan the job around the complete front end rather than the brake parts alone. Decide on the spindle style early, since the spindle drives the mounting and the way the caliper sits relative to the rim.
Many builders replace the front hoses, pads and bearing seals in the same session. With the hub off, it is a good moment to check the ball joints and tie rod ends for play. Inspect the rotor surface for scoring as well, and replace it if the friction face has worn below a usable thickness.
Wheel choice also affects the feel of the brakes. Tire width and offset change how much room the caliper has, so recheck clearance whenever the tire size changes. Keep a record of the template check and the torque on the lug nuts for future service.

Vehicle fitment
The manufacturer fitment list for this kit includes 1960–1986 Chevrolet C10, 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.
Four-wheel-drive trucks fall outside this kit’s 2WD specification. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Spindles must be supplied separately because the kit does not include Wilwood C10 Aluminum Modular Pro or Cpp X10 units. Run the Q117P template against your planned wheels to check clearance. Because brakes are safety-critical, a qualified technician should bleed the lines and verify pedal feel before the truck is driven.
What’s included
The front six-piston caliper, the two-piece 14-inch rotor on its billet aluminum hat, mounting brackets, stainless braided hoses and pre-assembled hardware are provided.
Not included: Spindles, in either the Wilwood C10 Aluminum Modular Pro or Cpp X10 style.
