my brake are not working and the pedal goes all the way to the floor, i change
the master cylinder but no change. i havent seen a leak any where.
Did you bench bleed the master cylinder before installing it? Did you bleed it after installation? You may also need to bleed all four wheels depending on how long you drove with a faulty master cylinder, as this can draw air into the system. What was the brake fluid level before you changed the master?
If car is old,rubber hoses may also be a issue
