Gettin\' brake lines off prop. valve

Any good tips on getting those old brake lines off the proportioning valve WITHOUT destroying the threads?!

At $150, I sure as hell don't wanna buy a new valve....[img]/wwwthreads_images/icons/shocked.gif[/img]


Thanks!

Re: Gettin\' brake lines off prop. valve

I don't think there is a totally fool proof method. I would suggest a liberal application of break-free or liquid wrench and allow at least a couple hours of soak time. Line wrenches are a must on brake lines to keep from rounding the corners off. Im pretty sure they made them out of butter. Also, make sure the lines are completely square when you reinstall the valve. I believe the valve is brass and very prone to stripping. I trashed one w/o even feeling any resistance. If you have or are planning to install some custom brake work, now might also be a good time to install an adjustable brake valve. The ones I've seen are at least as good as stock if not better, and quite a bit cheaper.

Re: Gettin\' brake lines off prop. valve

I found a spray called PB Blasters its in a yellow can and works incredibly well. 2-3 days worth of soaking and they should break free...at least mine did.

hope this helps

When I took mine off, I replaced all the lines so I cheated. I broke/cut the lines at the fitting and used a 6-point socket.

Re: Gettin\' brake lines off prop. valve

If your replacing all the lines, no problem, cut the lines, pull the porp valve off the frame, put it in a vise and use vise grips to turn the old lines out...I've cleaned up 5or6 that way without a problem.
or if its still on the frame and your replaceing the line just use vise grips on the fitting...

If you want to just loosen the fittings...good luck Soak very well with penetrating oil over several days to a week...

Re: Gettin\' brake lines off prop. valve

on top of using lube, use a visegrip to squeaze the line wrench, this will keep the line wrench from opening slightly and rounding off the corners on those really stubborn ones.

Re: Gettin\' brake lines off prop. valve

Good luck, I went throught the same thing you are going through about a weeek ago. In fact i am still working on it. Mine is a frame off so i needed to replace all the lines anyway. I dont have a vice but everything i have tried hasn't worked. And my didnt really want to trust my but to the old rusty thing anyway so i went with one of the adjustable ones from summit. $40. You will need to do some fabrication to make it fit though. good luck [img]/wwwthreads_images/icons/smile.gif[/img]

Re: Gettin\' brake lines off prop. valve

I had to replace the lines in my Tow vehicle, 84 Blazer. When I went to remove the lines from the valve I actually had to take the valve out of the chevy and put it in the vise. The line was rusted so bad that we had to heat it up. Never an easy job when your in a rush.
