Overview
The Baer Brakes Pro Plus 4301579S is a front disc brake kit for 1988–1998 Chevrolet and GMC C1500 2WD trucks and for 1992–1999 C1500 Suburban, Tahoe and Yukon models, finished in silver. It uses a 6-piston fixed caliper on a 14 inch two-piece slotted, drilled and zinc-plated rotor and is designed for wheels 18 inch or larger.
Billet aluminum hubs come assembled with premium bearings packed in Redline synthetic grease, along with billet dust caps. Rotors arrive pre-assembled with NAS high grade stainless hardware, and Baer manufactures the kit in Phoenix, Arizona. The React 2 inch drop spindles are needed for the system but are not included.
Key features
- Billet aluminum hubs assembled with premium bearings
- Redline synthetic grease packed into the bearings
- Billet dust caps for the hubs
- Stainless pistons and abutments paired with noise suppression clips
- Dual seals against dust, weather and pressure
- Two-piece 14 inch rotor, slotted, drilled and zinc-plated, with a billet aluminum hat
- Stainless braided hoses, DOT approved
Hub and bearing care
Billet hubs with pre-packed bearings are meant to be serviced as a unit rather than repacked on the bench. Check for wheel play by rocking the tire at the top and bottom with the lug nuts snug, and look for movement or heat after a drive. Keep the dust caps in place, since they limit water and grit reaching the bearing area.
On a heavier 2WD truck or one that sees rough ground, the front hubs carry extra loads. Inspect the hub seals and wheel studs at each tire rotation, and replace any stud that is bent or has damaged threads. Clean the hub face before fitting a wheel so the lug nuts seat evenly.

Confirm the React 2 inch drop spindles are installed before fitting the calipers, since they are not part of the kit. Template Q117P checks wheel clearance for the 18 inch minimum, and the wheel studs should be M14-1.50 x 47.5mm. Test the brakes carefully at low speed after bleeding the system.
