Overview
Part 4301512B is Baer Brakes’ Track4 front disc brake kit with a black T4 four-piston caliper and a 13 inch one-piece slotted, drilled and zinc plated rotor. It covers two-wheel-drive Chevrolet C10 and GMC C15 trucks from 1960 to 1986 and is intended for trucks already fitted with CPP 2.5 inch drop spindles.
The Track4 is made for wheels 17 inch or larger, which suits larger-wheel front ends. Owners start with drop spindles in place, and the kit adds the hubs, rotors, calipers and hoses on top of them.
Key features
- Black powder coated T4 four-piston caliper with stainless steel pistons
- Staggered piston arrangement to help even out pad wear
- Stainless steel abutments and noise suppression clips
- Dual seal design: dust and weather seals plus pressure seals
- One-piece slotted, drilled, zinc plated iron rotor at 13 inch
- Billet aluminum hubs with premium bearings and billet dust caps
- Stainless braided hoses with a DOT approved rating
- D0749 FMSI pad type
Choosing wheels and spindles
Drop spindles change the geometry of the front end, and the wheel is part of that setup. A wheel that clears the caliper on one spindle may not clear it on another, so the template and the wheel should be compared before the kit goes on. Wheel offset and backspacing also determine how much room is left behind the spokes for the caliper body.
Owners who run larger wheels often notice that tire width and sidewall height change steering effort and brake feel. Taller, wider tires add rotating mass, so the brakes work harder to stop the truck. Inspecting the hubs, dust caps and bearing seals at each wheel service helps keep the setup clean and quiet.
- Compare the template against the wheel first
- Note wheel offset and backspacing before mounting
- Keep hub seals and dust caps in good condition

Installation notes
Plan the job around the 5 x 5.00 inch bolt pattern and 1/2-20 x 2.25 inch studs, since lug nuts are not in the box. The billet hub bearings arrive assembled and packed with grease. Brake hoses and mounting brackets are supplied, but the drop spindles are not. Support the truck on stands before any wheel comes off, and check that the rotor clears the 17 inch wheel you plan to run.
What’s included
Billet hubs with assembled bearings, T4 calipers, 13 inch rotors, mounting brackets, stainless braided hoses, hardware and billet dust caps.
Not included: CPP 2.5 inch drop spindles and lug nuts.
