Overview
The Baer Brakes 4301587FR is a Pro Plus front brake system in Fire Red for 1973–1987 GMC and Chevrolet C10 pickups, half-ton, with 2WD drive. It uses a six-piston caliper working on a 14 inch two-piece rotor that is slotted, drilled and zinc plated, with a billet aluminum hat.
Modular 2.5 inch drop spindles are needed for this front end but are not included. The design targets wheels of 18 inch or larger, and Baer advises checking your wheel against template Q072P because wheel styles differ between manufacturers. The brake pads are the D0731 type, which is the pad the system is built around.
Key features
- Two-piece six-piston caliper with stainless steel pistons and abutments.
- Pistons are staggered to limit uneven wear on the pads.
- Caliper is machined from US-sourced forged or billet aluminum and powder coated in Fire Red.
- Dual dust and weather seals plus pressure seals.
- Slotted, drilled, zinc-plated vented rotor with a billet aluminum hat.
- Stainless noise suppression clips included.
- Steel braided hoses with stainless hardware, DOT approved.
Setting up the front end
A brake change on a steering axle is also a steering job. Spindle swaps and related parts can shift toe, camber and caster slightly, which affects tire wear and how the truck tracks at speed. An alignment after the install keeps the new hardware from wearing tires unevenly and keeps the steering centered.
Route the braided hoses so they sit clear of the tie rod, track bar and any moving suspension parts through full steering travel. Use the fasteners supplied and recheck them after a short drive. Watch the hose and fitting areas over the first few drives, since new lines settle once they are under pressure.
- Alignment after spindle changes
- Hose routing clear of steering linkage
- Recheck fasteners after the first drive

Vehicle fitment
Start with the 1973–1986 Chevrolet C10 and C10 Suburban, then the 1987 Chevrolet R10 and 1987–1988 R10 Suburban. The list continues with 1975–1978 GMC C15 and Suburban, 1973–1974 GMC C15/C1500 and Suburban, 1979–1986 GMC C1500 and Suburban, and 1987 GMC R1500 with 1987–1988 R1500 Suburban.
Trucks with four-wheel drive and any model years not shown in that list are not covered by this fitment. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Order the 2.5 inch drop modular spindles along with the kit, since they do not come in the box. Check wheel clearance against the 18 inch minimum and the Q072P template before mounting. The rotors arrive pre-assembled with stainless hardware, and the brackets and braided hoses are supplied. Steering-axle brake work is safest with a qualified technician, followed by a low-speed test before regular driving.
What’s included
The Fire Red kit includes the six-piston caliper, two-piece 14 inch rotors with billet aluminum hats, NAS high grade stainless rotor hardware, mounting brackets, and braided hoses with hardware.
Not included: the 2.5 inch drop modular spindles.
