Overview
The Baer Brakes 4301571S is an Extreme Plus front brake system in Silver for 1960-1986 Chevrolet and GMC C10 2WD 1/2 ton trucks. It also covers Suburban models from 1960-1966 and 1967-1986, GMC 3000 trucks from 1960-1966, C15 trucks from 1975-1978, C15/C1500 trucks from 1967-1974, and C1500 trucks from 1979-1986. The kit uses a 1-piece monoblock 6-piston caliper on a 14 inch, 2-piece slotted, drilled, zinc plated rotor.
This system is made for trucks equipped with Cpp X10 spindles or Wilwood C10 Aluminum Modular Pro spindles, and spindles are not included. The 14 inch Extreme Plus is designed for most 18 inch or larger wheels, and any wheel should be checked against template N117P.

Preparing an older truck
Trucks from the 1960s through the mid-1980s often have worn front hubs, tired bushings and corroded mounting surfaces. A brake upgrade is a good point to inspect these parts while the wheels and hubs are off. Look for play in the wheel bearings, cracks around the spindle, and rust that could affect how the brackets seat.
Because the brake kit depends on spindle fit, take time to confirm the spindle and steering components are sound before bolting anything on. Clean the hub face and check that the rotor sits flat. Older front ends also benefit from an alignment check after the work is done, since new brakes will expose any wear in the steering linkage.
- Inspect wheel bearings and seals
- Check spindles and steering linkage for wear
- Clean rust from mounting surfaces
