This system features the "Original" Baer 2-piston, pad guided caliper (PGC) mounted to a 13", 1-piece slot, drill, zinc plated 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 is designed to fit 94-04 Mustang (SN95) with OE spindles and hubs. Mounting brackets, stainless braided hoses and all necessary hardware are included. The 13" "Classic" system fits select 17" 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.** Fits 94-04 Ford Mustang w/OE Spindles and Hubs
