Overview
The Baer Brakes Track4 brake kit, part 4301597S, is a silver front disc brake system for 1960–1986 Chevy C10 and GMC C15 2WD half-ton trucks. The kit combines a 4-piston T4 caliper with a 13-inch vented, slotted and drilled rotor and is designed for use with Wilwood C10 Aluminum Modular Pro spindles, which are not included.
Baer designs the Track4 for wheels that measure 17 inches or larger, and wheel styles vary enough that a guaranteed fit is not possible. Lay the Q082H template against the planned wheel to check clearance before work begins.
Key features
- Four-piston T4 caliper with stainless steel pistons and abutments
- Staggered pistons designed to reduce uneven pad wear
- T-compliant dust and weather seals plus pressure seals
- Vented 13-inch 1-piece rotor, slotted, drilled and zinc plated
- Powder coated silver caliper, CNC machined from US sourced forged or billet aluminum
- Stainless steel noise suppression clips and stainless braided hoses
Things to check
Older trucks often have brake systems designed around drum brakes and a lighter front axle, so a disc upgrade changes the hydraulic balance. Check that the master cylinder can supply enough fluid for the new calipers and that the rear brakes still match the front. A proportioning valve or brake booster may need attention once front discs are fitted.
Inspect frame rails, steering components and spindle mounting surfaces for rust or cracks before new parts go on. Clean the mounting faces to bare metal so the brackets seat flat. Expect a bedding period during the first stretch of driving, when firm, repeated stops help pads seat evenly against the new rotors.
- Confirm master cylinder fluid capacity
- Clean spindle mounting faces before assembly
- Inspect steering linkage for wear

Installation notes
Because the Wilwood C10 Aluminum Modular Pro spindles are not included, they need to be in place before the T4 calipers and rotors can be mounted. Mounting brackets, stainless braided hoses and hardware are supplied. Brake lines and hydraulics are safety-critical, so have a qualified shop install and test the system.
