    Hi everyone ~

    I know this is the place to come, when you need answers!

    I have a 99 Mustang GT 4.6L Convertible. Recently, I have noticed that my front brake calipers aren't releasing like they're supposed to, especially when they get warm. When you jack the car up(Brakes warm to hot) I can only get about 1 revolution out of each side. I have heard several possibilities, but I want to hear from fellow Mustang lovers. Pins sliders all move freely Claiplers move freely everything is clean piston go back freely as well i'm lost

    If that doesn't work, could be a bad caliper....or two....

    loosen the bleed valve a bit and see if fluid is under high pressure. do not let any air in or let too much oil come out of it . after you let some fluid loose check for tight brake, start the car and pump the brakes a few times then see if the caiplers are still under pressure

    for future reference. usually you can use brake cleaner to make them functional normal again.
