Overview
Grabber Blue, part 4301388GB, is a Baer Brakes Pro Plus front disc brake system for half-ton 2WD Chevrolet and GMC C10 trucks from 1960 through 1987.
The kit runs a six-piston caliper and a 14-inch rotor for five-lug hubs on a 5×5.00 bolt pattern. The minimum wheel diameter is 18 inches, and the kit uses 1/2-20 x 2.25 inch studs. Billet aluminum hubs, stainless braided hoses, mounting brackets and hardware come with it. Spindles are not included.
Key features
- Six-piston 6P caliper painted Grabber Blue
- Staggered piston layout that helps spread pad wear
- Dual seals rated for dust, weather and pressure
- Stainless steel pistons, abutments and noise suppression clips
- Two-piece slot, drill and zinc plated rotor on a billet aluminum hat
- Billet hubs with premium bearings, billet dust caps and Redline synthetic grease
- Rotors pre-assembled with stainless NAS hardware
- Braided steel hoses marked DOT approved
Inspecting pads and rotors
A regular inspection catches problems before they become expensive. Measure rotor thickness at each pad change and replace the rotor once it is worn below its minimum thickness. Look for scoring, cracks near the slots, or a lip along the outer edge. Uneven pad wear on one side can point to a stuck caliper slide, a contaminated pad or a rotor that is running out.
The five-lug hub and wheel studs also deserve attention. Check that the nuts are tight after the first few drives and whenever a wheel has been removed. Keep the hub bearings lubricated and the dust caps in place to keep grit out. Replace worn pads in pairs so both sides brake the same way.
- Measure rotor thickness at each pad change
- Check caliper slides for smooth movement
- Retighten wheel nuts after the first drives
