Overview
The Baer Brakes 4302504MG is a Pro Plus 14.0 in rear disc brake kit finished in Monster Green for 2WD 60-87 Chevy and GMC C10 trucks. A 6-piston, 6P caliper clamps a 14 inch two-piece rotor that is slotted, drilled and zinc plated, set up for the rear axle.
The backing plate serves as both the caliper mount and the housing for a 1-piece park brake shoe assembly. The kit is built around the D0731 pad type, and the caliper uses dust and weather seals. The 14 inch Pro Plus suits wheels 18 inches or larger.
Key features
- 6-piston caliper with staggered pistons, which Baer says minimize uneven pad wear
- Stainless steel pistons, abutments and noise suppression clips
- Dual dust, weather and pressure seals on the caliper
- Slotted, drilled, zinc-plated 2-piece rotor on a billet aluminum hat
- Pre-assembled rotors with NAS grade stainless hardware
- Backing plate with integrated 1-piece park brake shoe housing
- Steel braided brake hoses, DOT approved, supplied with stainless hardware
- Caliper powder coated; components use US-sourced forged or billet aluminum
Caring for the finish and hardware
A powder coated caliper holds its color best when it is kept clean. Brake dust and road salt build up on the caliper body, and a rinse with mild soap and water removes them without harsh solvents. Avoid high-pressure washing aimed straight into the seals, since it can push water past the dust boot.
Stainless fasteners resist corrosion, but they still need the correct torque for your vehicle and a recheck after the first few drives. Caliper slide pins should stay clean and lightly lubricated. Keep the braided hoses away from heat sources and out of rubbing contact with the frame.
- Rinse the caliper after driving on salted roads
- Recheck bolt torque after the first few trail runs
- Inspect hose sleeves for abrasion
- Replace seals that show cracking
