This just started happening with my brakes, I do not know what could have caused it. When I apply the pedal i feel the brakes engaging, but then for about a second the pedal wants to come back out and the brakes feel as if they are not working, and it goes away. It does not do it every time it is hit or miss. It feels as if the pedal is jumping back really quick.
Could there possibly be air in the line? Would I need to bleed the system?
