I have an Audi a6, year 2000. My breaks were locking up every now and then and my break pedal was super tight. I did some research and found that i had to replace my abs sensors. I did that and now my breaks are acting the total opposite. My break pedal goes all the way to the floor and it is hard to stop my car. I tried to bleed the breaks but only two of them actually bleed.
could this be a blockage issue?
if so i feel like the blockage would cause my breaks to be hard such as too much pressure...
could it maybe be the master cylinders?
or did i just mess up my abs somehow?
