Brake Master Cylinder: Fundamentals and Basics
A master-cylinder will develop little or no pressure if air is trapped in cylinder bore. Normal brake bleeding will not remove air trapped within
Clamp the master-cylinder securely in a vice. It is usually best to clamp the side of the vice onto the flat surface that is used to secure the
There are two basic methods for bleeding master-cylinder, one utilizes stroking the master-cylinder to expel air from the cylinder bore while
Fill the master-cylinder with clean brake fluid.
The brake line fittings on the master-cylinder should be capped or plugged.
NOTE: Special "bench bleeding" plastic fittings are available which allow for recirculating the brake fluid back into the reservoir.
Using a dull object, slowly stroke the master-cylinder piston, air and brake fluid will be expelled from the brake line fittings. Prior to
Repeat this procedure 8-10 times or until no air is emitted from the outlet ports.
When finished, cap the outlet ports and install the master-cylinder.
Fill the syringe (one especially designed for brake bleeding) with clean brake fluid.
Insert the end of the syringe into one of the outlet ports on the master-cylinder.
Slowly compress the syringe and back flush the brake fluid through the master-cylinder.
A combination of air and brake fluid will be emitted from the inlet port in the fluid reservoir.
Repeat this procedure until only brake fluid is emitted into the reservoir.
Cap the outlet ports and install the master-cylinder.
