I have had my truck at a shop for a week and they can't figure out what is going on with my breaks. The truck has been sitting for 2 years and when I started driving it the front left caliper locked up on the rotor. The mechanic replaced the hoses on both sides replaced the calipers now the right side is not getting fluid to it. He can't figure it out says the Master cylinder is good the only thing he can think that is causing it is the ABS Module. One side is getting fluid and working beautifully the right is not getting fluid at all....don't want the huge expense of replacing the ABS module if that is not it...any help would be appreciated.
