Overview
Built for 1960–1986 Chevrolet C10 and GMC 1000, C15 and C1500 2WD half-ton trucks, the Baer Brakes Track4 front brake system 4301512GB is a T4 four-piston disc brake kit with a 13 inch slotted, drilled rotor.
The caliper is finished in Grabber Blue, and the billet aluminum hubs come assembled with premium bearings already packed with Redline synthetic grease. The kit is set up for a Cpp nodular iron 2.5 inch drop spindle, which must be bought separately. The 13 inch Track4 suits wheels 17 inch or larger.
Key features
- T4 caliper with four staggered pistons to even out pad wear
- Stainless steel pistons, abutments and noise suppression clips
- T-compliant dual seals guard against dust, weather and pressure
- CNC machined forged or billet aluminum parts with a powder-coated finish
- One-piece slotted, drilled, zinc-plated vented rotor
- Billet dust caps paired with hubs that carry premium bearings
Choosing the right pads
Pad choice affects how the brakes feel as much as how they stop. Street driving, towing and hard off-road use each place different heat loads on the pads and rotor. A pad that suits daily driving may fade under sustained braking on a grade, so the intended use should guide the selection.
Pads and rotors should be bedded in together when new. Gentle stops at moderate speed help transfer an even layer of friction material onto the rotor. A pulsing pedal or squeal after bedding can point to uneven pad transfer, glazing or a warped rotor, and those should be checked before the truck is loaded or towed.
- Match pad compound to street, towing or trail use
- Bed in new pads and rotors with gentle stops
- Investigate pedal pulsation or squeal after bedding

Installation notes
Install the Cpp nodular iron 2.5 inch drop spindle first, since the hubs bolt to it and it does not come in the kit. Test-fit with the Q082H template against your intended wheel, because Baer does not promise fit with every wheel style. Bleed the brake lines and check pedal feel before any road use.
What’s included
Baer includes the T4 caliper, the 13 inch rotor, billet aluminum hubs with bearings and dust caps, mounting brackets, stainless braided hoses, and hardware.
Not included: the Cpp nodular iron 2.5 inch drop spindles.
