Brakes building up pressure and not releasing
We replaced the hydro boost and master cylinder on our 2001 Ram 2500 Diesel. After bleeding the brakes we are having issues with the brakes building up pressure. Have to stop on the side of the road and bleed again. This has happened several times. Any suggestions on why this is happening and how to fix it?

Do you have old rubber brake lines in the front? Sometimes these can fail inside the lumen of the line and cause a clapper valve like situation where the calipers cannot return to the relaxed position...Mark

I had a brand new hydraulic hose do that once. Under pressure the fluid would get under the liner and close the hose off. with no pressure the hose looked fine and compressed air went through it one way. took a while to figure that one out. lesson learned blow through hoses both ways
