Overview
The Baer Brakes 4301571FR is a front Extreme Plus brake system with a Fire Red six-piston caliper, built for 2WD half-ton Chevrolet C10 and GMC C15 and C1500 trucks. It fits 1960–1986 Chevrolet C10 applications, several Suburban years and a set of GMC models, and it mounts to Wilwood C10 Aluminum Modular Pro spindles or Cpp X10 spindles, which are sold separately.
The system centers on a one-piece monoblock 6S caliper with six stainless steel pistons, clamping a 14-inch two-piece vented rotor that is slotted, drilled and zinc plated. Baer also supplies stainless braided hoses and all mounting brackets, so the front brakes can be installed once a compatible spindle is in place.
Key features
- One-piece Monoblock 6-piston 6S caliper with a powder coated Fire Red finish
- Caliper body CNC machined from US-sourced 2618 aluminum forging, manufactured in Phoenix, Az
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to minimize uneven pad wear
- Dual seals guarding against dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor with a billet aluminum hat, pre-assembled with NAS high grade stainless hardware
- Stainless braided hoses and mounting brackets included
Pad and rotor maintenance
Rotors and pads wear together, so a front brake change is a good time to measure both. Check rotor thickness against the minimum stamped on the casting, and look for heat cracks, scoring or a lip at the outer edge. A rotor that has worn below spec can shudder under braking and transfer heat unevenly into the hub bearings.
Slotted and drilled rotors help shed gas and water, yet the slots also collect dust and pad material. Clean the caliper bracket and the hat face when the wheels come off, and bed in new pads gradually over several stops before any hard braking. Keep track of lug torque after the first few drives, since a loose wheel can warp a rotor quickly.

Vehicle fitment
It fits 1960–1986 Chevrolet C10 pickups, 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 and three-quarter-ton models are outside the stated fitment, since the kit is labeled 2WD and 1/2 Ton. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Spindles are not included, so confirm the truck already carries Wilwood C10 Aluminum Modular Pro or Cpp X10 spindles before planning the install. Baer’s N117P template should be laid against the wheel you intend to run to check clearance around the 14-inch rotor and caliper. Brakes are safety-critical, so have a qualified technician check the finished installation before the truck returns to road use.
What’s included
The kit contains the 6S monoblock caliper, the two-piece rotors pre-assembled with NAS high grade stainless hardware, all mounting brackets, and stainless braided hoses with hardware.
Not included: spindles, and wheels.
