Pinion Brake Caliper Speed Bleeder

Bleeding brakes generally requires two people. You had to have one person pump the brake pedal while you had another open and close the bleeder screw. You had to coordinate the openings and closings with the pumper. If you didn’t coordinate the timing correctly you could end up with more air in the system than when you started.

This can be further complicated by limited access to the pinion brake caliper due to rear end bracing.

To simplify the brake bleeding process we use the Speed Bleeder screw with the built-in check valve.  This is truly a one-person device.   Once installed, it becomes a permanent part of the brake system.

When it is time to bleed your brakes, you loosen the Speed Bleeder screw a 1/4  turn and pump your brake pedal.  When the pedal is depressed the pressure generated opens the check valve letting air and brake fluid out of the end of the Speed Bleeder screw.  When you release the pedal and it returns to the up position, the check valve closes and prevents any air from reentering the system through the Speed Bleeder screw.  When bubble free fluid is evident you close the Speed Bleeder screw.  In the closed position it works just like your stock bleeder screw and prevents any brake fluid from leaking out.
