Overview
The Baer Brakes 4301579MG is a front Pro Plus brake kit finished in Monster Green, covering 1988–1998 Chevrolet and GMC C1500 2WD trucks and 1992–1999 C1500 Suburban SUVs. It is a bolt-together front disc upgrade built around a six-piston caliper and a 14-inch two-piece rotor.
Baer’s 6P caliper uses fixed mounting with staggered pistons, a layout meant to reduce uneven pad wear over time. The caliper carries stainless pistons and noise suppression clips, and the kit uses D0731 pads. Baer rates the 14-inch Pro Plus for wheels 18 inches in diameter or larger.
Key features
- Six-piston 6P fixed caliper with a Monster Green powder-coated finish
- Staggered piston layout to minimize uneven pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- 14-inch two-piece slot, drilled and zinc-plated rotor with billet aluminum hat
- Billet aluminum hubs with premium bearings and billet dust caps
- Stainless braided brake hoses with mounting brackets and hardware included
Wheel clearance and offset
Wheel clearance matters on any big-brake conversion because the caliper and rotor take up more room inside the wheel than stock parts do. Before buying wheels, compare the wheel’s back spacing and offset to the caliper body and the inner face of the rotor. Rubbing marks on the inner wheel lip after the first drive are a sign that clearance is too tight.
Tire size also changes clearance at full steering lock and under suspension compression. Taller tires can rub the fender or the frame near the front axle, so check both sides with the truck loaded and turned lock to lock. Recheck the lug nut torque after the first few miles because new wheels can seat slightly.
- Measure the caliper body against the wheel barrel before mounting
- Check clearance at full left and right steering lock
- Use the Q117P template before ordering wheels

Installation notes
Rotors ship pre-assembled with NAS high-grade stainless hardware, so the hub and rotor assembly is ready to mount. Drop spindles are not part of this kit, so the 2-inch React spindles must already be on the truck or purchased separately. Check wheel clearance with the Q117P template before fitting wheels. Brake components are safety-critical, so a qualified technician should install and bleed the system.
