Overview
Grabber Blue Baer Brakes Extreme Plus, part 4301627GB, is a front brake system for 2WD Chevrolet and GMC C1500 trucks from 1988 to 1998 and C1500 SUVs from 1992 to 1999 that use React 2-inch drop spindles.
Baer assembles the Grabber Blue kit around a 6S monoblock caliper with six pistons and a 14-inch two-piece rotor with a billet aluminum hat. The package also includes stainless braided hoses, brackets and hardware, and the rotors arrive with NAS stainless hardware already pre-assembled. The D1247 pad type is used throughout the system.
Key features
- Six-piston monoblock caliper made in Phoenix, Az
- Caliper body CNC machined from U.S.-sourced 2618 aluminum forging
- Stainless pistons, abutments and noise suppression clips
- Staggered pistons designed to reduce uneven pad wear
- Dual seals for dust, weather and pressure
- Powder-coated Grabber Blue finish
- Billet aluminum hubs with premium bearings packed in Redline synthetic grease
Drop spindle setup
A drop spindle changes the geometry of the front end, so the brake components need to clear the knuckle, steering arm and tie rod with the truck at ride height. Before fitting new brakes, confirm the spindle bushings, ball joints and tie rod ends are in good shape, because worn parts can shift the caliper position under load.
After any spindle work, the front end should be aligned, since caster and camber can change with the drop. Recheck the tire wear pattern after the first few drives, and make sure the steering returns to center without drift. Keep a record of setup measurements so future service is easier.
- Inspect ball joints and tie rod ends
- Check steering arm clearance at full lock
- Schedule a front alignment after installation
- Recheck bolt torque after the first drives
