Ronnie Posted September 22, 2021 Share Posted September 22, 2021 Start by getting some flare wrenches, AKA tubing wrenches, to help prevent rounding off the nuts. Spray repeatedly for a few days with penetrating oil. I like Kroil penetrating oil if you can find it. PB Blaster is good to. 1 Link to comment Share on other sites More sharing options...
2seater Posted September 22, 2021 Share Posted September 22, 2021 If you are talking about the valve located at the rear axle on the drivers side, it will be likely that at one or more of the three lines will twist off if there is much rust under the car. I hope not and Ronnie's advice is spot on. Link to comment Share on other sites More sharing options...
Padgett Posted September 22, 2021 Share Posted September 22, 2021 Proportioning valve is in front, rear is a three-way distribution or splitter. 1 Link to comment Share on other sites More sharing options...
