Overview
The Baer Brakes Pro Plus brake kit, part number 4301570HO, is a Hugger Orange front disc brake system for 2WD GM C10 trucks, covering 1960–1986 Chevrolet C10 and GMC models. It combines a six-piston fixed caliper with a 14 inch two-piece rotor and is built to suit most wheels 18 inch or larger.
Baer makes the calipers in Phoenix, Arizona, from CNC-machined forged or billet aluminum. The caliper has a powder-coated Hugger Orange finish, and the system uses the D0731 pad type for owners fitting Wilwood C10 Aluminum Modular Pro or Cpp X10 spindles.
Key features
- Six-piston fixed caliper, two-piece design, in Hugger Orange powder coat
- Staggered pistons intended to limit uneven pad wear
- Pistons, abutments and noise clips use stainless steel construction
- Dual seals against dust, weather and pressure
- Slotted, drilled, zinc-plated two-piece rotor on a billet aluminum hat
- Uses the D0731 FMSI pad type
- Braided hoses with DOT approval
Wheel and hub considerations
The wheel is part of the brake system. A rotor and caliper sized for wheels 18 inch or larger need enough space between the spokes and the caliper body, so wheel offset and backspacing matter as much as diameter. Before mounting, rotate the wheel through its full travel with the assembly in place to test clearance.
Hub-to-rotor fit also deserves attention. Clean the mounting face and confirm the rotor sits flat against the hub, since any runout shows up as pedal pulsation. Tighten lug nuts in a star pattern and check them again after the first drives, once the parts have settled.
- Check backspacing against the caliper body
- Clean the hub face before mounting the rotor
- Inspect the wheel studs for damage

Installation notes
No spindles come in the box, so a Wilwood C10 Aluminum Modular Pro or Cpp X10 spindle set must be in place before the calipers and rotors go on. Check the wheel against template Q117P first, since fit with every wheel style cannot be confirmed.
What’s included
The kit supplies the six-piston calipers, the two-piece rotors on billet aluminum hats with NAS high grade stainless hardware, all mounting brackets, and stainless braided hoses with their hardware.
Not included: Spindles, which must be a Wilwood C10 Aluminum Modular Pro or Cpp X10 set.
