Overview
The Baer Brakes 4301588CY is an Extreme Plus front brake kit finished in Comp Yellow for 1973 to 1987 Chevrolet and GMC C10, C15 and R10 pickups set up for 2WD 1/2 ton service. Its 1-piece Monoblock 6-piston, 6S caliper clamps a 14 inch two-piece slotted, drilled, zinc-plated rotor.
This kit is built around Dse Forged Aluminum 2.5 Inch Drop Modular Spindles. The spindles are not part of the package, so plan for them separately. The box includes mounting brackets, stainless braided hoses and the stainless hardware that comes pre-assembled with the rotors.
Key features
- 1-piece Monoblock, 6-piston, 6S caliper manufactured in Phoenix, Az
- CNC machined from U.S. sourced 2618 aluminum forging
- Powder coated caliper finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons designed to reduce uneven pad wear
- Dual seals guarding against dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor with billet aluminum hat
Pad and rotor pairing
Pads and rotors wear as a pair, and a worn pad can score a rotor surface quickly. Slotted rotors help carry gas and debris away from the pad face, but slots can also wear pads faster when the friction material is too aggressive for the rotor. Choose a pad compound suited to the driving you do, and bed new pads and rotors with a series of moderate stops before any hard braking.
Modular spindles change the mounting geometry, so the rotor and caliper must sit true to the hub before the wheel goes on. Check rotor runout after installation, and look for rubbing between the caliper and the wheel at full steering lock. A check of the caliper bolts after the first few drives is a sensible habit on any rebuilt front end.
- Bed in new pads with progressive stops
- Watch for pulsation that signals rotor warping
- Keep caliper slide pins clean and lubricated

Installation notes
Confirm the modular spindles are on the truck or ordered alongside this kit before mounting the caliper. Baer recommends comparing your wheel against template N072P, because wheel styles vary and fit is not guaranteed across every design. Brake components are safety-critical, so have a qualified shop install and bleed the system.

Not included: the 2.5 inch drop modular spindles and wheels.
