Overview
The Baer Classic Series front brake kit, part 4301681R, is a 2-piston red caliper system for listed Chevrolet and GMC C1500 2WD trucks and SUVs. It is designed for vehicles using Az Pro Performance React 2-inch drop spindles, Baer p/n 6800258, and the kit carries a 13.15 inch rotor.
The integral hub rotor arrives ready to install, with races in place and bearings packed with Redline synthetic grease. Dust caps, mounting brackets, stainless braided hoses and the necessary hardware are included, along with the ABS tone ring. The caliper uses the FMSI D0731 brake pad.
Key features
- Aluminum, 2-piston, pin-drive caliper with a red powder coat
- Black Baer logo painted on the red caliper
- Slotted, drilled and zinc-plated integral hub rotor
- Works with both ABS and non-ABS applications
- Stainless braided brake hoses included
- Uses the common FMSI D0731 brake pad
- Dust and weather seals and packed bearings for a ready-to-install hub
Drop spindles and brake clearance
Changing the front end height with drop spindles alters the geometry that the brakes depend on. The caliper, rotor and hub must still sit square to the spindle, and the brake hose must reach the caliper without tension through the full range of suspension travel. After any spindle change, check the hose routing and confirm the caliper sits centered over the rotor before driving.
On an older truck, the front hubs, bearings and seals are often worth inspecting when a brake system is replaced. Packed bearings and fresh seals help keep grease and water out of the braking area. Worn steering components and tired shocks also change how the front end loads the brakes, so they are commonly serviced at the same time.
- Confirm the spindle and hub match before fitting the rotor
- Check hose length and routing at full suspension travel
- Re-torque the caliper bracket bolts after the first few drives

Vehicle fitment
Chevrolet entries are the 1988–1998 C1500, 1992–1999 C1500 Suburban and 1995–1999 Tahoe. GMC entries are the 1988–1999 C1500, 1992–1999 C1500 Suburban and 1992–1999 Yukon. The fitment notes specify trucks equipped with React 2 inch drop spindles.
Vehicles outside these entries are not covered, including 2000-and-later Silverado 1500 and Sierra 1500 models and four-wheel drive trucks, since this system is 2WD only. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Check that your drop spindles match Baer p/n 6800258 before fitting the rotor and caliper. The rotor arrives with races installed and bearings packed, so it can go on the spindle directly. Front brake work on a lowered or drop-spindle front end should be done by a qualified mechanic.
What’s included
The kit includes the 2-piston caliper, the 13.15 inch integral hub rotor with races and packed bearings, dust caps, mounting brackets, stainless braided hoses, the ABS tone ring and the hardware for installation.
Not included: the Az Pro Performance React 2-inch drop spindles (Baer p/n 6800258) the kit is designed to fit, and wheels of at least 17 inches.
