Ok!! Even with the Intake manifold off, I can't get the brakes lines to budge!! I've sprayed the fittings for 10 days straight with PB Blaster and used my 10mm line wrench tool. I'm assuming since my car is a 94 and they've never been touched, they're seized and done. Any other ideas on getting my lines loose from the proportioning valve? My valve is leaking!!!!!!!!!!!!!! I would hate to take it to the dealership to get my prop valve replaced and the brake lines redone. It seems as if my only option is to cut my brake lines and redo them.

About how much will it cost to do those 5 lines running to the prop valve in stainless steel lines??

 

are you sure your turning the wrench the correct way? i've had problems with the lines going into the rubber flex's and usually use a pair of visegrips and a hammer...

 

if you have access to a torch, you can heat the joint where the line goes into the prop valve then try tightening it first just a little bit if it will tighten a bit then is should break loose and you will be able to take it off.... although the 10mm line wrench is the ideal tool, ive found that a good pair of vice grips will give you more leverage to break it loose

 

don't take a torch to it, have you ever seen brake fluid burn lol that ****'s hot as f*** use a some vise grips on them and if that don't work then do what you have to do and get some line and a bender and a flare tool and make a new line your freaking self good luck just don't lite that **** on fire, lmao
