QuestionHow does one remove the proportioning valve on an '84 Jeep CJ-7?
AnswerHenry,
If you are just removing it, remove the brake lines, then remove the bolts that secure it to the frame.
If you are replacing it, do the same, but after installing the brake lines, you will have to bleed the system to remove the air. Be careful installing the brake lines so you don't cross thread them. Start them by hand, then use a line wrench to tighten them.
The brake fluid is caustic, so don't get it on the paint. Get a can of "brake cleaner" to spray down the area when finished.
