    I need help!!! I'm having trouble with my 2007 tacoma prerunner 5spd.
    I can't get the back breaks to stop locking up while driving. I've installed new master cylinder. And I'm still having trouble. Any suggestions what it can be? Thanks in advance

    They are locking up when exactly. When you press the brake pedal? or just going along and bam lock up?

    Some details would enhance the responses you will get.

    have you messed with your suspension much, cause the rear brake proportioning valve has allot to do with rear brakes and it changes if you have raised or lowered your suspension.

    I've had a bonded friction pad let go from the metal shoe and get wedged between the opposite brake shoe pad and drum. IF you back up it releases, when you start driving it suddenly locks solid!
