Overview
The Baer Brakes Track4 front brake system, part number 4301597HO, is a complete front disc brake kit for Chevrolet C10 and GMC half-ton trucks built from 1960 to 1986. Its 2-piece, 4-piston T4 caliper is finished in Hugger Orange and clamps a 13 inch vented rotor.
The kit is built for GM C10 trucks from 60-87 with two-wheel drive and 1/2 ton models. It mounts to Wilwood C10 Aluminum Modular Pro spindles, and the rotor suits wheels 17 inch in diameter or larger. Not every wheel style will clear it, so check fit before buying wheels.
Key features
- 2-piece, 4-piston T4 caliper manufactured in Phoenix, Arizona
- CNC machined from U.S.-sourced forged or billet aluminum
- Powder coated Hugger Orange finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons to minimize uneven pad wear
- Dual dust, weather and pressure seals with T compliant dust and weather seals
- 1-piece slotted, drilled, zinc plated rotor
Before you buy
A front disc conversion changes more than the brakes. Before ordering, look at the spindle, the hub bearing and the wheel offset, since all of them determine whether a 13 inch rotor and a 4-piston caliper will sit correctly behind a 17 inch or larger wheel. Measure the clearance between the caliper body and the inside of the wheel with the rotor in place.
Pad choice matters as well. The D0749 pad type is the one this kit is built around, and worn pads should be replaced in pairs on each axle so braking stays even. Bleed the system completely after any hose or caliper work, and confirm that the braided hoses clear the suspension at full steering lock and full suspension travel.
- Confirm spindle and template fit before buying wheels
- Check wheel offset and inner clearance
- Replace pads and rotor together when wear is uneven
- Use fresh brake fluid after installation

Installation notes
The kit is built around Wilwood C10 Aluminum Modular Pro spindles, which are not part of the package, so the truck needs them in place before this brake kit is mounted. Lay the Q082H template against the wheel you plan to run first, because wheel designs vary.
What’s included
The package has the 2-piece, 4-piston T4 caliper, a 13 inch 1-piece slotted, drilled, zinc plated rotor, all mounting brackets, stainless braided hoses and hardware.
Not included: Wilwood C10 Aluminum Modular Pro spindles.
