Overview
The Baer Brakes Pro Plus 4301586FR is a front disc brake kit for 1973–1988 Chevrolet and GMC 2WD half-ton C10, C15 and R-series trucks, with Fire Red calipers. Its six-piston two-piece caliper clamps a 13 inch slotted, drilled and zinc-plated rotor, and the design targets classic pickups that run 17 inch or larger wheels.
Each caliper is CNC machined from US sourced forged or billet aluminum and manufactured in Phoenix, Arizona. Baer built the system around Dse forged aluminum modular spindles with a 2.5 inch drop, and those spindles are not part of this kit.
Key features
- Staggered pistons aim to minimize uneven pad wear
- Stainless pistons, abutments and noise-suppression clips
- Dual seals guard against dust, weather and pressure
- Powder coated Fire Red finish on the caliper body
- Two-piece slotted, drilled and zinc-plated rotor with a billet aluminum hat
- Steel braided hoses carrying a DOT approval
- Pads specified by FMSI D0731
Choosing brake pads
Pads are the wear item that most directly controls how the brakes feel. The FMSI D0731 pad pattern sets the shape and mounting, but the compound inside determines bite, dust and noise. Match the friction material to how the truck is driven, whether that is mostly highway miles, weekend cruising or hauling loads.
Bed in new pads by making several moderate stops from speed before normal use, which transfers an even film onto the rotor. Check pad thickness at each tire rotation and watch for uneven wear across the two pads, which can point to a sticking slide or a seized piston.
Keep the caliper slide pins clean and lightly lubricated with high-temperature brake grease, and keep grease off the pad friction surface.
- Pad compound affects noise, dust and bite
- Bed in new pads before heavy loads or steep grades
- Watch for uneven pad wear on one side
- Replace pads once they reach the wear indicator

Vehicle fitment
It fits 1973–1986 Chevrolet C10 with Suburban variants, 1987 Chevrolet R10 with the 1987–1988 R10 Suburban, 1973–1978 GMC C15 and C15/C1500 with Suburban variants, 1979–1986 GMC C1500 with Suburban variants, and 1987 GMC R1500 with the 1987–1988 R1500 Suburban. It is applied to 2WD trucks only.
Vehicles from 1972 and earlier, models from 1989 onward, and 4WD trucks fall outside this list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Dse forged aluminum modular spindles need to be in place before the calipers and rotors are mounted. Set template Q072H against your 17 inch or larger wheels to verify clearance, since Baer advises checking wheel fit for each wheel style. Brake work is safety-critical, so bleed the lines and test the pedal before the truck returns to the road.
What’s included
The kit provides the 6-piston caliper, 13 inch two-piece rotors with NAS high grade stainless hardware pre-assembled, mounting brackets, stainless braided hoses and matching hardware.
Not included: Dse forged aluminum modular spindles.
