How to properly bleed your new Hydraulic Bearing

Always have the AN -4 line with the bleeder valve at the top when the bearing is properly installed.  It is OK to swap the lines on the swivel fittings if necessary.  Remember the line with the bleeder valve must be at the top position!

Fill the master cylinder with DOT 3 or DOT4 brake fluid. DO NOT USE SILICONE BASED FLUID or DOT 5 FLUID!! Use of silicone or synthetic fluid will damage the o-rings resulting in leaks and or damage to the assembly.

After the master cylinder is filled, bleed the bearing assembly. Example: Pump the pedal 3 to 4 times, with the bleeder valve open and the end of the opening submerged in a cup partially filled with brake fluid. This will release fluid and air trapped in the system.

Continue the bleeding process until all of the air is removed from the system. Always keep fluid in the master cylinder while performing the bleeding process. Now reach into the cup and tighten the bleeder fitting while still under fluid. Set the cup aside and then be sure to tighten the bleeder valve.

Once the bleeding is complete refill the master cylinder, just don’t fill it all the way to the top. The fluid level should be ½” to ¾” from the top. This will allow room for the brake fluid in the reservoir when the bearing self adjusts. Unlike brakes, the fluid level will rise in the master cylinder, as the clutch wears, not lower.
