Re: brake problems

check your wheel cylinders for leaks and if you cant find any leaks you probably have air in the lines

Re: brake problems

Check all of the obvious as woods mentioned but if all looks good then the new master cylinder may be defective.

I went through three of them some years back until I changed parts store and got a different brand. Be sure and follow the directions explicitely on bench bleeding. You can do it mounted on the truck but requires two people.

When you bleed start with the rear passenger side and then the driver's side. Then front passenger side and then driver's side.
