Overview
The Baer Brakes 4301588FR is an Extreme Plus front brake system kit in Fire Red for 1973 to 1987 Chevrolet and GMC C10, C15 and R10 pickups in the 2WD 1/2 ton configuration. It combines a 1-piece Monoblock 6-piston, 6S caliper with a 14 inch two-piece slotted, drilled, zinc-plated rotor.
The title pairs the kit with Dse Forged Aluminum 2.5 Inch Drop Modular Spindles, and those spindles are not included. Brake hardware, mounting brackets, stainless braided hoses and the rotors’ pre-assembled stainless hardware do come in the box, and the pads use the popular D1247 pad type.
Key features
- 1-piece Monoblock, 6-piston, 6S caliper manufactured in Phoenix, Az
- CNC machined from U.S. sourced 2618 aluminum forging
- Powder coated finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor with billet aluminum hat
- Rotors pre-assembled with NAS high grade stainless hardware
Before you buy
Fixed multi-piston calipers like this one clamp the rotor from both sides, so pad contact is shared across all six pistons. Because the pistons are staggered, pad wear is spread more evenly, but that only works when the pads seat square and the slide surfaces move freely. Pads are a wear item, and their friction material should suit the way the truck is driven, whether that is mostly street use, towing or trail work.
Brake hoses and fluid deserve attention whenever the caliper is changed. Braided lines flex less than rubber, which helps keep pedal feel firm, but they still need inspection for chafing and leaks. Bleed the system with fresh fluid after the hoses are installed, and use a fluid rated for the demands of the braking system.
- Check pad thickness at every wheel service
- Inspect braided hoses for chafing near the spindle
- Replace worn rotors in pairs

Installation notes
Because the 2.5 inch drop spindles are sold separately, confirm your truck already has or will receive the matching modular spindles before fitting the calipers and rotors. Check wheel clearance against template N072P, since Baer cannot guarantee fit to every wheel style. Brakes are a safety system, so have the work done by a qualified technician.
