Bleeding, Maintenance and Troubleshooting
We strongly recommend that you use a pressure bleeder with a rubber bladder that separates the air side from the fluid side. If this is not possible follow the following procedure:
  1. Fill the master cylinder reservoir 3/4 full with clean, fresh brake fluid.
  2. Push and hold the pedal down.
  3. Open the bleeder valve on the caliper, or wheel cylinder, until fluid is released. If you are bleeding a Dual Cylinder Brake Pedal Assemby you will need to open a bleeder screw on the front brakes and the rear brakes at the same time.
  4. Close the bleeder valve and release pedal.
  5. Wait three to five seconds and repeat.
Pumping will only aerate the fluid and prevent complete bleeding. Complete your bleeding procedure all the way around the car. Bleed each caliper until clear, air-less fluid comes out of each bleeder screw. When finished be sure to run master cylinder only 3/4 full of fluid.

  1. Do not exceed 1500 lbs pressure
  2. Use AUTOMOTIVE DOT 3 or 4 brake fluid only
  3. Bleed screws must be pointed up for proper bleeding
  4. Use grade 8 bolts for mounting
  5. Inlet ports are 1/8" pipe thread
  6. Seal all fittings with Loctite - NOT teflon tape
  7. Make sure wheels turn freely after bleeding
  8. Do not use your brake pedal as a foot rest
  9. Test drive
Prior to each racing event or weekend out it is a good idea to follow this checklist to make sure your brakes are up to their maximum potential.
  1. Check for leaks around calipers, pistons, fittings and lines.
  2. Bleed once around the car to replenish the system with fresh fluid.
  3. Check pad wear.
  4. Make sure all wheels rotate in a drag-free condition.
When replacing pads you must clean the exposed portion of the caliper piston with brake cleaner or brake fluid before the piston is retracted into the piston housing. This procedure will avoid damage to the piston seals.

When the car is raced weekly, we recommend replacing the seals once at mid season and rebuilding between seasons. For lesser used cars, seal replacement between seasons is fine. Always flush the system with fresh brake fluid after any seal replacement or rebuild.
