Master cylinder without booster. Single bore master cylinders: These unboosted hydraulic Master Cylinders are actuated by foot effort, via the brake pedal. The brake pressure is related to actuation force and depends on the piston bore size: the smaller the bore, the higher the pressure.
The master cylinder does not automatically bleed the air out of the piston when you fill it, this has to be performed âon the benchâ, in other words, out of the vehicle. You can bleed it in the car, but it takes longer and requires two people- one to watch for bubbles and one to push the brake pedal.
