This system features the "Original" Baer 2-piston, pad guided caliper (PGC) mounted to a 11.29", 1-piece slot, drill, zinc plated integral hub rotor. The PGC caliper comes in a red powder coated finish with a black logo, includes dust/weather seal's and uses the popular D412 pad type. The system includes premium bearings with races pre-installed, dust caps, mounting brackets and all necessary hardware. The 11.29" "Classic" system fits select 14" and most 15" or larger wheels. **IMPORTANT: This system is designed for vehicles with a 15/16” master cylinder and proper pedal ratio. For manual brake setups, a 7/8” master cylinder can be used so less effort is required to apply the brakes. Any master larger than 15/16” will require too much pedal input to generate proper line pressure for your brake system.**
