Jeepman Posted August 23, 2010 Share Posted August 23, 2010 The Brake line should be 3/16ths line... Link to comment Share on other sites More sharing options...
mopwrd340 Posted August 23, 2010 Author Share Posted August 23, 2010 i appreciate it that is what it looked like looking underneath it . the hose fittings look like 3/8ths do i need adapters to do this swap. Link to comment Share on other sites More sharing options...

There should be no adapters necessary. Except where the hard ;ines come out of the metering block ("combination valve" ... but it isn't on an MJ) below the master cylinder.

kastein Posted September 3, 2010 Share Posted September 3, 2010 The switch that goes on the proportioning valve block? Stomp on the pedal as hard as you can and it should unstick. Make sure you follow the special MJ brake bleeding procedure or your brakes will slowly get worse and worse till they're nearly as bad as they were before. EDIT: nevermind you got rid of the backup circuit... no special procedure needed. Link to comment Share on other sites More sharing options...

Eagle Posted September 5, 2010 Share Posted September 5, 2010 tried this morning wouldnt go out can it be taken apart . Anything can be taken apart. If you do, then it won't have brake fluid in it, you have to re-bleed the system, and the light will come on again so you'll be right back where you are now. It might help if you remove the plastic switch part on the top of the metering block -- that's the part the wires go to. Then stomp on the brakes and see if the slider will center itself.

Jeepman Posted September 7, 2010 Share Posted September 7, 2010 Check to make sure the e-brake pedal is all the way up before taking anything apart... Link to comment Share on other sites More sharing options...
