My car jumps when I'm holding the brakes down
Usually this has to do with 1 of two possible issues. Either your rotors are warped creating a pulse when you step on the brake or your alignment is of causing the same problem. If its the alignment a good way to test is let go of the wheel for just a second while on an open straight road does your vehicle Veer to one way or the other?
