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 79-93 Fox Mustang's with 94-04 (SN95) spindles and hubs. Mounting brackets, stainless braided hoses and all necessary hardware are included. The 13" "Classic" system fits select 17" or larger wheels. **Must use 94-04 SN95 Spindles and hubs. Does NOT fit 79-93 spindles.** **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 1979-93 Ford Mustang w/94-04 SN95 Mustang Spindles & Hubs (Does NOT fit OE 79-93 spindles)
