Overview
The Baer Brakes 4301627B is a front Extreme Plus brake system in Black for 1988 to 1998 Chevrolet and GMC C1500 2WD trucks and 1992 to 1999 C1500 2WD SUVs with React 2 inch drop spindles. The caliper is a 6S, 1-piece Monoblock, 6-piston unit that clamps a 14 inch, 2-piece slotted, drilled, zinc plated rotor.
The Black finish is a powder coat over the aluminum caliper body. Beyond color, the kit brings a billet aluminum hub with premium bearings, stainless braided hoses and the mounting brackets, and it uses the D1247 pad type.
Key features
- 1-piece Monoblock design with 6-piston, 6S caliper made in Phoenix, AZ
- Caliper machined from a US-sourced 2618 aluminum forging
- Black powder coated exterior
- Stainless pistons with abutments and noise suppression clips
- Staggered pistons reduce uneven pad wear
- Dual seal design for dust, weather and pressure
- Two-piece slotted, drilled and zinc plated rotor with billet aluminum hat
- Hubs fitted with premium bearings, Redline synthetic grease and billet dust caps
Black finish care
A black powder coat on a brake caliper shows brake dust more than lighter colors do, so a periodic wipe-down keeps the caliper looking clean and makes it easier to spot leaks or fluid seeping around the seals. Heat from repeated stops can also discolor the finish near the pistons, which is normal wear rather than a defect.
Bigger brake packages change the look of the front wheel, so the wheel’s inner clearance matters as much as the caliper appearance. Keep wheel lug nuts torqued to the vehicle’s specification and recheck them after the first few drives.
- Wipe the caliper periodically to reveal leaks early
- Expect some heat discoloration near the pistons
- Recheck lug nut torque after the first drives

Vehicle fitment
It fits the 1988 to 1998 Chevrolet and GMC C1500 trucks, the 1992 to 1999 Chevrolet and GMC C1500 Suburban models, the 1995 to 1999 Chevrolet Tahoe and the 1992 to 1999 GMC Yukon.
The fitment covers 2WD trucks and SUVs only, and years outside the listed ranges are not included. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
No spindles come in the box, so the React 2 inch drop spindles must already be on the truck. Stainless braided hoses, mounting brackets and hardware are included. Hold a wheel against template N117P before choosing wheels, since Baer does not guarantee fit across every wheel design.
Brakes are safety-critical, so have the work checked by a qualified person before driving.
What’s included
The kit includes the Black 6S caliper, 14 inch rotors with NAS high grade stainless hardware, billet aluminum hubs with premium bearings, billet dust caps, stainless braided hoses, and all mounting brackets and hardware.
