Overview
Grabber Blue is the caliper finish on the Baer Brakes 4302504GB, a Pro Plus 14.0 in rear disc brake system for 60-87 Chevy and GMC C10 2WD trucks. The kit combines a 6-piston caliper with a 2-piece rotor that is slotted, drilled and zinc plated.
The caliper is powder coated and uses stainless steel pistons, abutments and noise suppression clips. The D0731 pad type fits this system, and the caliper has staggered pistons to even out pad wear. The 14 inch Pro Plus is meant for wheels of at least 18 inches, and the rotor sits on a billet aluminum hat.
Key features
- Six pistons in a floating caliper, staggered to minimize uneven pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Dual seals against dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor with a billet aluminum hat
- Rotors come pre-assembled with stainless hardware
- Baer backing plate combines the caliper mount with a 1-piece park brake shoe housing
- Stainless braided hoses and hardware included
- Components are CNC machined from US-sourced forged or billet aluminum
Parking brake setup
A rear disc kit with a 1-piece park brake shoe assembly in the backing plate changes how the parking brake is set up. The shoe assembly works alongside the disc, so the cable must pull the lever through its full travel. Adjust the cable so the lever engages firmly without dragging the wheel when released.
Park brake cables are not part of the package, so existing cables usually get reused. Inspect them for kinked sheathing, rust at the ends and sticky movement before installing. Replacing a worn cable during the same job is often easier than working around a failed one later. Test the parking brake on a slight grade in a safe place after adjusting it.
- Lubricate cable ends and pivot points
- Confirm the lever returns fully when released
- Replace cables that stick or fray
- Test hold on a slope before regular driving
