Overview
The Baer Brakes 4301627FR is a front Extreme Plus brake system in Fire Red for Chevrolet and GMC C1500 2WD trucks from 1988 to 1998 and C1500 2WD SUVs from 1992 to 1999 fitted with React 2 inch drop spindles. The kit centers on a 1-piece Monoblock, 6-piston, 6S caliper clamped to a 14 inch, 2-piece slotted, drilled, zinc plated rotor.
Front disc upgrades for these trucks usually mean a larger rotor and a caliper with more pistons. This kit supplies both, along with a billet aluminum hub, stainless braided hoses and the mounting brackets needed to fit them. It uses D1247 pads by FMSI number, and the caliper is powder coated in Fire Red.

Before you buy
A larger front rotor and multi-piston caliper change how the whole hub assembly behaves, so it is worth looking at the rest of the front end before ordering. Pads, wheel clearance and steering components all interact with brake hardware on a lifted truck. Measure the wheel you intend to run against the template before deciding it will clear.
Bigger rotors generally need more wheel clearance and may call for a wheel with a different offset. Many owners replace pads together with the rotors, since new metal and friction material wear in together. Brake fluid is also worth checking, because a larger caliper draws more fluid per stroke and older fluid can reduce pedal feel.
- Confirm wheel clearance with the template before mounting
- Plan to replace brake pads and fluid at the same time
- Check the steering linkage for play before installation

Vehicle fitment
The kit fits the 1988 to 1998 Chevrolet C1500 and GMC C1500, the 1992 to 1999 Chevrolet C1500 Suburban and GMC C1500 Suburban, the 1995 to 1999 Chevrolet Tahoe and the 1992 to 1999 GMC Yukon.
Coverage is for 2WD models with React 2 inch drop spindles; 4WD versions and model years outside the listed ranges are not covered. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Spindles are not included, so React 2 inch drop spindles must already be installed on the truck. Mounting brackets, stainless braided hoses and hardware come with the kit. The 14 inch rotor fits most 18 inch or larger wheels, and template N117P helps confirm clearance for the wheel you plan to run.
Brake work is safety critical, so have the finished installation checked before the truck is driven on public roads.
What’s included
The kit includes the 6S caliper, the 14 inch rotors with pre-assembled NAS high grade stainless hardware, billet aluminum hubs with premium bearings packed with Redline synthetic grease, billet dust caps, stainless braided hoses, and all mounting brackets and hardware.
Not included: React 2 inch drop spindles.
