Overview
The Baer Brakes Track4 front brake system, part number 4301512FR, is a front disc brake kit for Chevrolet and GMC 2WD 1/2 ton trucks from 1960 through 1986, including the C10 and C15 series. It uses a 4-piston T4 caliper in Fire Red on a 13 inch rotor and is made for trucks equipped with a 2.5 inch drop modular spindle.
Billet aluminum hubs come assembled with premium bearings packed with Redline synthetic grease, and the kit adds stainless braided hoses, mounting brackets and hardware. The Track4 is designed to fit most 17 inch or larger wheels, so check wheel clearance before installation.
Key features
- 4-piston T4 caliper manufactured in Phoenix, Az
- Caliper body CNC machined from forged or billet aluminum made in the USA
- Powder coated Fire Red finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to minimize uneven pad wear
- Dual seals for dust, weather and pressure; T compliant dust and weather seals
- 13 inch 1-piece slotted, drilled, zinc plated rotor
- Billet aluminum hubs with premium bearings and billet dust caps
Pad and rotor wear
Brake pads and rotors wear together, and a kit like this one is easiest to maintain when both are inspected at the same time. Look for pad material that has thinned unevenly, scoring or a lip on the rotor edge, and a pedal that feels soft or pulses under braking. Those signs point to a worn component rather than a setup problem.
Hubs and bearings also need periodic checks. Inspect the dust caps for leaks, and listen for grinding while turning at low speed. Keep the area around the caliper clean when working near the seals, and avoid getting grease or cleaner on the pad friction surface.
- Replace pads and rotors as a set when one shows heavy wear
- Check brake fluid level after pad changes
- Clean the rotor face with brake cleaner before fitting pads

Installation notes
Spindles are not included, so the truck must already have, or be fitted with, the 2.5 inch drop modular spindle named in the fitment note. Check wheel clearance with the Q082H template before mounting, because Baer cannot guarantee fit with every wheel style. Brake work involves hydraulic lines and high-torque fasteners, so have a qualified technician bleed the system and test the pedal before driving.
What’s included
The kit includes the T4 caliper mounted to the 13 inch 1-piece rotor, billet aluminum hubs assembled with bearings and billet dust caps, all mounting brackets, stainless braided hoses and hardware.
Not included: spindles.
