Additional Notes:
  • 15/16″ can be used Power or Manual.  Customers that prefer softer pedal feel with less pedal effort use 15/16″ for Power Brakes
  • 1″ with Power is based on good engine vacuum numbers, and that the booster is working corretly
  • Drag race applications with dual rear calipers should use a 1 1/8″ Bore Remaster
  • Port Configuration is based off Drivers seat position.  LP – Left port (Fender side), RP- Right Port (Motor Side)
