Overview
The Baer Brakes 4301571HO is a front Extreme Plus disc brake system in Hugger Orange for 1960–1986 Chevrolet C10 and GMC C15 2WD half-ton trucks. It pairs a 14-inch two-piece slotted, drilled and zinc-plated rotor with a one-piece monoblock, six-piston 6S caliper.
Baer built the kit for trucks running Wilwood C10 Aluminum Modular Pro spindles or Cpp X10 spindles, and the spindles are not supplied. Rotors arrive pre-assembled with NAS stainless hardware, and the package adds mounting brackets and stainless braided hoses, so the front end arrives as one complete set.
Key features
- One-piece monoblock caliper with six stainless steel pistons
- Caliper body CNC machined from a U.S.-sourced 2618 aluminum forging
- Powder coated finish, manufactured in Phoenix, Arizona
- Staggered pistons designed to minimize uneven pad wear
- Dual seals guard against dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor with billet aluminum hat
- Stainless steel abutments and noise suppression clips
Before you bolt it on
Big brake kits change how a truck stops, so the front end should be checked as a whole once the new parts are in place. A larger rotor and a six-piston caliper put more clamping force on the pads, which can make a worn steering linkage, tired ball joints or loose wheel bearings easier to feel under braking. Look over those parts before the first drive and re-torque the wheel lugs after the first few miles.
Pad choice and wheel clearance matter just as much. Pads are matched to a friction spec, so keep the same pad type when replacing them. Check that the wheel barrel clears the caliper body and the spindle hardware on full steering lock. Brake fluid that has been sitting in an old system should be flushed when lines are replaced, because moisture lowers boiling point over time.

Installation notes
Spindles are not included, so the truck must already run Wilwood C10 Aluminum Modular Pro or Cpp X10 spindles before the kit goes on. Check the N117P template against the wheel you plan to use, since the 14-inch rotor is meant for wheels 18 inches or larger.
What’s included
The kit includes the 6S monoblock caliper, pre-assembled two-piece rotors with stainless hardware, mounting brackets, and stainless braided hoses with hardware.
Not included: spindles.
