Overview
The Baer Brakes 4301390FR is a Fire Red Extreme Plus front brake kit for 60-87 Chevy/GMC 2WD 1/2 ton trucks with a 5 lug, 5×5 inch bolt pattern. It replaces the front disc brakes on classic GM C10-style pickups and Suburbans with a 14 inch rotor and a 6-piston caliper.
The centerpiece is a 1-piece Monoblock 6-piston, 6S caliper that is CNC machined from US sourced 2618 aluminum forging and finished with a powder coat. Staggered pistons are designed to reduce uneven pad wear, and dual seals guard against dust, weather and pressure. The pads are the popular D1247 FMSI type.
Key features
- 1-piece Monoblock 6-piston, 6S caliper machined from 2618 aluminum forging
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons to minimize uneven pad wear
- Dual dust, weather and pressure seals
- 2-piece slotted, drilled, zinc-plated 14.0 Inch rotors with billet aluminum hat, pre-assembled with NAS high grade stainless hardware
- Billet aluminum hubs with premium bearings packed with Redline synthetic grease and billet dust caps
- Mounting brackets, stainless braided hoses and hardware included
Before you buy
Front disc upgrades on classic trucks change more than stopping power, because the rotor, caliper, hub, bearings and spindle all share the same loads. A change to one part can shift wear onto the others, so it helps to look at the front end as one system. Measure the spindle already on the truck and confirm it matches the bolt pattern and drop height the kit expects before any parts are opened.
Pedal feel depends on clean, bled lines and a caliper that slides freely on its pins. Braided lines resist swelling under pressure, which helps keep the pedal firm through repeated stops. After the first few drives, check the wheel studs for proper torque and look at the pads for even contact on the rotor face.
- Measure the existing spindle before ordering
- Compare wheel backspacing with the template
- Replace pads and rotors as a matched set
- Inspect braided lines for chafing each season

Installation notes
The w/Cpp 2.5 Inch Drop Modular Spindle named in the fitment notes is not included, so it must be sourced to pair with these 14 inch rotors. Baer recommends checking Template N117P against the wheel you plan to run, since the kit is designed for wheels 18 inch or larger and fit with every wheel style cannot be guaranteed.
Bleed the hydraulic system fully after the stainless braided hoses are connected, and test the pedal before driving on public roads.
What’s included
The kit includes the 6S Monoblock caliper, the 14.0 Inch two-piece rotors with stainless hardware, billet aluminum hubs with bearings and billet dust caps, mounting brackets, stainless braided hoses and hardware.
Not included: the 2.5 inch drop modular spindle.
