Overview
A Hugger Orange Pro Plus 14.0 in rear brake system from Baer Brakes, part number 4302504HO, built for 2WD 60-87 Chevy and GMC C10 trucks. Baer built the system around a 6-piston, 6P caliper that mounts to a 14 inch two-piece rotor, which is slotted, drilled and zinc plated.
The rotor carries a billet aluminum hat, and the rotors arrive pre-assembled with NAS high grade stainless hardware. The backing plate houses a modern 1-piece park brake shoe assembly. The 14 inch Pro Plus is meant for wheels 18 inches and up, and the caliper uses the D0731 pad type.
Key features
- Six pistons in a 6P caliper, with staggered pistons to even out pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Dust, weather and pressure dual seals
- Two-piece slotted, drilled and zinc-plated rotor on a billet aluminum hat
- Pre-assembled rotor and stainless hardware set
- Backing plate that acts as caliper mount and park brake shoe housing
- Stainless braided hoses and hardware included with the kit
- Powder coated caliper finish in Hugger Orange
Brake pad and rotor wear
Pads are the wear part of a disc brake, and their friction material thins with every stop. Check pad thickness at each tire rotation by looking through the caliper window. Uneven wear on one side often points to a sticking slide pin rather than a pad problem, so inspect the caliper hardware before replacing pads.
A rotor with a slotted and drilled surface clears gas and water more quickly, though slots and holes still wear over time. Look for cracks around the drilled holes, heavy scoring, and a blue or dark tint that suggests overheating. When rotors are replaced, install fresh pads so the new faces seat properly against each other.
- Check pads through the caliper window
- Measure rotor thickness against the minimum stamped on it
- Bed in new pads with gentle stops
- Clean hub faces before mounting the rotor
