    Default help troubleshoot brakes 93 chevy 1.2 ton

    Brakes are not mushy. But it takes a lot of effort to stop. There is fluid to the min line in the master cylinder, the line comming out of the powerbooster looks good.

    Do I need a power booster, mastercylinder, or both?

    I always replace the booster and master cylinder as a set. I worked a few years in the family parts store and my experience was that if I just sold a master cylinder the customer was back soon for a booster. The fluid leaking from the mc would damage the diaphragm in the booster. If money is tight try the one, but as my mechanic likes to say.......its a hand grenade and the pin has been pulled.

    When I do this (replace master c and power booster drum) will I have to bleed the brakes?

    X2 on replacing the master and booster as a set. You will have to bleed the system as well. Before you purchase the parts check your wheel cylinders. You will probably find them seeping and if so now's the time to change them.
