Overview
The Baer Brakes Track4 front brake system in Monster Green, part number 4301512MG, is a complete front disc brake kit for 2WD half-ton Chevrolet and GMC C10 trucks. It uses a T4 4-piston caliper clamping a 13.0 Inch vented rotor. The kit fits C10, C15 and 1000 series trucks and Suburbans from 1960 to 1986, plus the 1987–1989 Suburban.
The kit is designed for use with a 2.5 inch drop spindle, a Cpp modular spindle with a 5 lug, 5×5 bolt circle. Billet aluminum hubs come with premium bearings packed in Redline synthetic grease and billet dust caps. The calipers are powder coated, and the kit uses the D0749 FMSI pad type.

Front disc brake care
A front disc brake kit replaces the stock rotors, calipers and pads at the hub, so the braking system and the steering geometry around it need to work together. Before fitting a kit like this one, look at the rest of the front end: the spindle, the wheel bearings, the brake lines and the master cylinder all affect how the brakes perform. Upgrading calipers and rotors without matching the hydraulic system can leave the pedal feeling soft or uneven.
Pads wear at different rates depending on driving style and load, so inspect them at each service and replace them before the backing plate contacts the rotor. Check rotors for scoring, heat cracks and thickness below the minimum stamped on the casting. Hub bearings should be checked for play and kept greased; a noisy or loose hub is worth investigating before it becomes a wheel-bearing failure on the trail.
- Check pad thickness at every wheel service
- Inspect hoses for chafing where they pass the suspension
- Re-torque lug nuts after the first few drives
- Bleed the system after any line is opened
