Overview
The Baer Brakes 4301391FR is a Fire Red Extreme Plus front brake system for 2WD 1/2-ton Chevrolet and GMC C10-series trucks from 1960 to 1986. It combines a 1-piece monoblock 6-piston caliper with a 14-inch, two-piece slotted, drilled and zinc-plated rotor, and it is designed to work with a 2.5-inch drop modular spindle on a 6-lug, 6×5.50-inch bolt pattern.
The minimum wheel diameter is 18.0 inches, so the kit suits trucks running 18-inch or larger wheels. It covers Chevrolet C10 pickups and Suburbans, plus GMC 1000, 1000 Series, C15 and C1500 trucks in the years covered below.
Key features
- One-piece monoblock 6-piston 6S caliper, CNC machined from US-sourced 2618 aluminum forging
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to reduce uneven pad wear
- Dual seals for dust, weather and hydraulic pressure
- Two-piece slotted, drilled, zinc-plated vented rotor with a billet aluminum hat, pre-assembled with NAS high-grade stainless hardware
- Billet aluminum hubs with premium bearings packed in Redline synthetic grease and billet dust caps
- Powder-coated Fire Red finish with D1247 pad type
- Stainless braided hoses and mounting brackets included
Before you buy
Choosing a front brake kit for an older truck starts with the rest of the front end. A monoblock caliper and a larger rotor change the load that the hub, spindle and wheel bearings carry, so the spindle geometry and bearing condition matter as much as the brake parts. Because the spindle is supplied separately, confirm it is installed and torqued correctly before the brake assembly goes on.
Wheel choice matters too. A larger rotor usually needs clearance inside the wheel, so compare the wheel’s backspacing and inner barrel against the caliper body before buying wheels or tires. Steering and suspension parts that have been in service for decades may also need inspection, since worn joints can show up once braking forces increase.
- Inspect ball joints and tie rod ends before installation
- Check pad clearance after the first few stops
- Re-torque lug nuts after the first road or trail run

Installation notes
The 2.5-inch drop modular spindles are not supplied, so they must be in place before the brake assembly is mounted. The rotors arrive pre-assembled, and the stainless braided hoses and brackets come with the kit. Check wheel clearance with the N117P template, since Baer cannot guarantee fit with every wheel style. Brake hydraulics and heavy hubs call for a qualified installer.
What’s included
The kit contains the Fire Red 6S monoblock caliper, two-piece rotors pre-assembled with stainless hardware, billet aluminum hubs with bearings and billet dust caps, mounting brackets, stainless braided hoses and hardware.
Not included: 2.5-inch drop modular spindles.
