What is the proper sequence in which to bleed my brakes when using the Mityvac pump for vacuum brakeLast Updated: July 25, 2019
When using the vacuum bleeding method to bleed brake systems on vehicles which are rear wheel drive the sequence should start with the wheel closest to the master cylinder and end with the wheel which is farthest from the master cylinder.
Example: LF wheel, RF wheel, LR wheel, RR wheel
However, when vacuum bleeding brake systems on vehicles which are front wheel drive the sequence will change. These systems use a diagonal configuration for safety purposes. On this system the sequence should start with the wheel closest to the master cylinder as before, however the next wheel in the sequence will be diagonally aligned with that wheel.
Example: LF wheel, RR wheel, RF wheel, LR wheel.
LF - Left Front
RF - Right Front
LR - Left Rear
RR - Right Rear
