Overview
Fire Red is the caliper finish on the Baer Brakes 4302504FR, a Pro Plus 14.0 in rear disc brake system for 2WD 60-87 Chevy and GMC C10 trucks. It pairs a 6-piston, 6P caliper with a 14 inch two-piece rotor, so the rear axle gets a single matched kit.
The rotor is slotted, drilled and zinc plated, and its hat is billet aluminum. The backing plate also houses a park brake shoe assembly. The D0731 pad type applies to this kit, and the caliper seals are dust and weather seals.
Key features
- Six-piston 6P caliper with staggered pistons that reduce uneven pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Dual dust, weather and pressure seals
- Slotted, drilled, zinc-plated 2-piece rotor on a billet aluminum hat
- Rotor and hardware arrive together, with NAS grade stainless fasteners
- Backing plate with a built-in 1-piece park brake shoe housing
- Stainless braided hoses supplied with the kit
- Caliper powder coated; components use US-sourced forged or billet aluminum
Inspection and service intervals
A floating caliper moves on slide pins so both pads press the rotor evenly. When the pins seize from dirt or old grease, one pad wears faster and the pedal can feel uneven. Remove the caliper during pad service, clean the pins and bores, and apply a brake-safe lubricant designed for caliper slides.
The dust and weather seals keep grit and water away from the piston and pins. Check them for cracks, tears or lost lubricant whenever the pads change. Keep the braided hoses clear of heat and moving parts, and look for seepage at the fittings during each inspection. Brake fluid should be replaced on a regular schedule, not only after a failure.
- Check slide pins for free movement
- Inspect seals at each pad change
- Look for seepage at hose fittings
- Bleed the system after any hose replacement
