Overview
The Baer Brakes 4301587GB is a Pro Plus front disc brake kit in Grabber Blue for owners of 1973–1987 Chevrolet and GMC C10 trucks, half-ton, with 2WD drive. Its six-piston 6P caliper grips a 14 inch two-piece rotor that is slotted, drilled and zinc plated, with a billet aluminum hat.
The system is built for 2.5 inch drop modular spindles that are not supplied with the kit. The 14 inch Pro Plus is designed to suit most wheels of 18 inch or larger, uses FMSI D0731 pads and works with the Q072P template for wheel checks. Wheel styles differ, so compare your wheel before buying.
Key features
- Staggered piston layout on the 6-piston caliper to help even out pad wear.
- Caliper body machined from forged or billet aluminum, made in the USA and finished in Grabber Blue powder coat.
- Stainless pistons, stainless abutments and stainless noise suppression clips.
- Dual dust, weather and pressure seals on each caliper.
- Rotor with billet aluminum hat, two-piece slotted, drilled and zinc-plated surface.
- NAS high grade stainless hardware comes pre-installed on the rotors.
- Stainless braided hoses rated DOT approved.
Spindle and hub planning
The spindles decide how this front brake mounts, so they belong in the plan before any other part is ordered. Confirm that the hub, bearing and steering components are compatible with the spindle style you choose. A mismatched spindle can throw off rotor alignment and cause pulsing that is easy to blame on the brakes.
Once mounted, bed the pads in with a series of moderate stops at low speed, letting the brakes cool between runs. Re-torque caliper bolts after the first short drive and check the rotor for heat discoloration. Pads and rotors wear in together, so replacing one without the other can leave a surface that squeals or pulls.
- Verify hub and bearing compatibility
- Match pad compound to tow or trail use
- Re-check caliper bolts after the first drive

Installation notes
Plan around the missing spindles first, because the 2.5 inch drop modular spindles are a separate purchase. Compare the 18 inch minimum wheel diameter and the Q072P template before buying wheels. Rotor hardware is pre-assembled, and the mounting brackets and stainless braided hoses ship in the kit. A front brake job on a steering axle is best handled by an experienced shop, followed by a short low-speed test.
What’s included
The kit includes the 6-piston Grabber Blue caliper, two-piece 14 inch rotors with billet aluminum hats, NAS high grade stainless hardware, all mounting brackets, and stainless braided hoses with hardware.
Not included: the 2.5 inch drop modular spindles.
