This system features the 6-piston, 6P caliper mounted to a 14", 2 piece slot, drill, zinc plated rotor. The 6P caliper has D.O.T compliant dust and weather seals and uses the popular D0731 pad type. Rotors are pre-assembled with NAS high grade stainless hardware. Baer’s unique backing plate not only acts as a caliper mount, but also houses a modern 1-piece park brake shoe assembly. Stainless braided hoses and hardware are also included. The 14” Pro+ fits most 18” or larger wheels.
