How do you replace a master cylinder on a 1994 Pontiac grand am?

Answer 1

This is kinda a complicated question to be asked here but I will do my best to answer it for you. First you will have to remove the original, One nut on either side of the master cylinder should take care of that, you will also have to remove the lines and any plugs coming from the unit. I suggest you do this first as it makes it easier if the Master Cylinder isn't moving around. Once you get the old one off you will have to "bench bleed" the new one. There should be instructions in the box for that procedure. Once that is done you will put the new one on the same way you took the old one off, and bleed the the master cylinder again by having a helper push the pedal down and hold it while the line is loose, but not removed, once you tighten the line he/she can let off the pedal, repeat till NO air is seen in the fluid, Then you will want to bleed the brakes at each wheel starting with the passenger rear first, then Driver rear, Passenger front, driver front, in that order. Hope this helps.
