No need to tie them together. You just want a proportioning valve in the line to the rear brakes to reduce the brake pressure so that when you apply the brakes firmly and the weight shifts to the front wheels, the rear brakes won't lock up first. At least that's my understanding of how the system should work.

I have a line running out of that to the rear brakes and a separate line running to the front. I need to tie these two lines together?

Upgraded the manual brakes to power and front " disk brakes. Do I nee a "brake proportioning valve" for the front and " rear or just the rear or neither. the proportioning valve goes -between- the frt and rear, and yes you should have it for best brake performance. the manufacturers wouldn't have wasted money on a part they didn't need. btw and fwiw, if you have front disks, 14x6" hornet/concord wheels will definitely fit without problems. 15x7" mopar steelies would likely fit, with something like 215/60s, if you wanted to go that way. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _____________________________________________________________ Are you prepared for your exam 4TestsMail - Free email you can access from anywhere! http://www.4testsmail.com/ _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
