Overview
The Baer Brakes Track4 front brake system, part number 4301512HO, is a T4 four-piston disc brake kit with a 13 inch slotted, drilled, zinc-plated rotor for 1960–1986 Chevrolet C10 and GMC 1000, C15 and C1500 2WD half-ton trucks. The caliper is finished in Hugger Orange.
The T4 caliper is machined in Phoenix, Arizona, and the billet aluminum hubs arrive assembled with premium bearings packed with Redline synthetic grease. The kit mounts to a 2.5 inch drop modular spindle, which is sold separately. The 13 inch Track4 is designed for wheels 17 inch or larger.
Key features
- Four-piston T4 caliper with staggered pistons to minimize uneven pad wear
- Stainless steel pistons, abutments and noise suppression clips
- T-compliant dual seals for dust, weather and pressure
- CNC machined from US-sourced forged or billet aluminum with a powder-coated finish
- One-piece slotted, drilled, zinc-plated vented rotor
- Billet dust caps and billet aluminum hubs with premium bearings
Hub and bearing care
Hub-mounted brake systems depend on the hub and bearings staying in good condition. After a short drive, feel the hub and caliper area for unusual heat, which can point to a dragging pad or a tight caliper. Check for play by rocking the wheel at the top and bottom, and look for grease leaking past the seals.
Brake hardware should be checked after the first few drives on any new installation. Lug nut torque can settle as the wheel and hub seat, so re-check it. Keep the billet dust caps in place to limit road grit and moisture reaching the bearings.
- Feel the hub for abnormal heat after a short drive
- Check wheel bearings for play
- Re-check lug nut torque after the first drives

Installation notes
The spindle is not in the box, so the 2.5 inch drop modular spindle must be in place before the hubs and brackets are mounted. Lay the Q082H template against the wheel you plan to run, because Baer will not guarantee fit with every wheel style and manufacturer. Bleed and test the brakes before driving.
