Overview
The Baer Brakes 4301587CY is a Pro Plus front brake kit in Comp Yellow for 1973–1987 Chevy and GMC C10 half-ton trucks with 2WD drive. The 6P caliper is a two-piece fixed unit that clamps a 14 inch two-piece rotor, slotted, drilled and zinc plated, mounted to a billet aluminum hat.
The package expects 2.5 inch drop modular spindles, and those spindles are excluded from the box. Baer built the 14 inch rotor for most wheels of 18 inch or larger and recommends the Q072P template to confirm wheel fit before purchase. The pads are the popular D0731 type, so replacement pad planning is simple.
Key features
- Six-piston 6P caliper with staggered pistons to promote even pad wear.
- CNC machined caliper body from US-sourced forged or billet aluminum.
- Comp Yellow powder-coated finish on the caliper.
- Stainless steel pistons, abutments and noise suppression clips.
- Dual seals for dust, weather and hydraulic pressure.
- Two-piece slotted, drilled, zinc-plated rotor with billet aluminum hat.
- Rotors pre-assembled with NAS high grade stainless hardware.
- Steel braided hoses, DOT approved.
Pad and rotor pairing
Pad compound should match how the truck is used. Street driving, towing and trail work each put different heat and debris on the friction surface, so a pad that suits one may glaze or fade under another. Choose pads with the FMSI number in mind and review the compound’s intended use range before buying.
Check rotor surfaces for scoring, a lip at the outer edge, and blue or glazed areas that point to overheating. Measure rotor thickness at several points during service and replace a rotor that is worn beyond its minimum. Clean the hub face and wheel mounting surface before reinstalling wheels so the rotor sits flat.
- Pad compound matched to driving use
- Check for glazing or blue discoloration
- Clean hub and wheel mating surfaces

Four-wheel-drive versions, GM models not named in this list, and other model years are outside the stated fitment. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Spindles are not in the box, so secure the 2.5 inch drop modular spindles before starting the install. Compare the 18 inch minimum wheel diameter and the Q072P template before buying wheels. The rotors come with hardware already assembled, and the braided hoses and brackets are included. Front brake work on a steering axle should be finished by a qualified technician and followed by a low-speed test drive.
What’s included
The Comp Yellow kit includes the 6P caliper, two-piece 14 inch rotors with billet aluminum hats, NAS high grade stainless hardware, all mounting brackets, and steel braided hoses.
Not included: the 2.5 inch drop modular spindles.
