Q: I have replaced the break pads, calipers, and rotors on my 2003 ford explorer. My breaks keep locking up. I have also replaced the master cylinder.

asked by on

I have replaced every thing I can think of to do with the breaks. What am I missing? Is the abs module bad?

My car has 140000 miles.
My car has an automatic transmission.

Check the combination valve on the brake system. If the valve is sticking, then the fluid could be getting trapped and not returning. To check this valve, loosen the brake line on the back side of the valve (the side to the calipers) and see if the calipers move. If they do, then the valve is sticking. If they do not move, then the ABS module is sticking. If you need further assistance with your brakes sticking, then seek out a professional, such as one from Your Mechanic, to help you.

Q: Cold the trans shifts great but when it get warm it's like it's in neutral

The transmission most likely has internal fluid leaks in the pressure control circuit of the valve body. The leak gets worse as fluid heats up and leaks more. Have the transmission pressures checked at a transmission shop.
