Overview
The 4301628FR is Baer Brakes’ Extreme Plus front brake system in Fire Red, made for 2WD GM C1500 trucks from 1988 through 1998 and C1500 Suburban and Yukon SUVs from 1992 through 1999. Each kit centers on a 1-piece Monoblock 6-piston caliper, the 6S model, paired with a 15 inch two-piece rotor.
Baer manufactures the caliper in Phoenix, Arizona. Rotors are drilled, slotted and zinc plated, and the kit uses D1247 pads, dust and weather seals and billet aluminum hubs. Built for trucks running React 2 inch drop spindles, it needs the front end checked against the fitment section below.
Key features
- Fire Red powder-coated 6S calipers with a 1-piece Monoblock, 6-piston body
- CNC-machined parts made from U.S.-sourced 2618 aluminum forging
- Stainless steel pistons, plus abutments and noise clips
- Staggered piston layout that helps even out pad wear
- Dual dust, weather and pressure seals
- Zinc-plated, slotted and drilled two-piece rotor with a billet aluminum hat
- Billet aluminum hub assemblies lubricated with Redline synthetic grease
Pad choice and wear
Pads are the part of a brake system that wears fastest, and their material shapes how the whole setup behaves. A harder compound lasts longer and suits towing or steep grades, while a softer compound grips cold and feels more responsive in town. Choose the pad to match how the truck is actually driven rather than the most aggressive option available.
Pads and rotors wear as a pair, so replacing one without the other often leads to uneven contact and noise. Bedding in new pads with a series of moderate stops helps transfer an even layer to the rotor face. Keep the hardware clean and free of grit so the pads move smoothly in their brackets.
- Match pad compound to your typical driving
- Replace pads and rotors together when wear is uneven
- Clean and lubricate slide points during pad changes
