I lost the drive dogs on the vacuum pump thats why i lost steering and breaksWhat's the level in your power steering reservoir? If empty/low, check for leaks .if overfilled you may be looking at a sticking control valve in the PS pump. A quick way to check this is rev the engine up to high rpm and see if you have any assist. When the control valve sticks down pressure is returned to the reservoir through the relief at low rpm.
