I'm new here any help with problem would be appreciated. Have a 2000 F150 2WD. The front passenger side brakes do not release. I've replaced pads, caliper, rotor. When I was bleeding the line it seemed the amount of fluid was not adequate. What would be the next recommended step to repair? I've heard "replace flex brake line" but then suggestions moved into master cylinder & a "device in the system that costs $400"? can't remember the name of the part however.

 

I'd replace the flex hose. Least expensive & probably the culprit.

 

The 400 part is your ABS module.

 

The system is Contaminated with Petroleum or mineral oil grease. It swells the flex hose and all rubber brake components. You need to flush the Master Cylinder. If you will replace the flex hose without cleaning the system it will just fail again. Flush it with denatured alcohol first and flush it again with many Brake Fluid.

Don't use old or opened brake fluid more than a month old especially if the container is big.

 

is your parking brake on?lol jk flush the cylinder like previously mentioned
