HOrnbrod Posted August 17, 2013 Share Posted August 17, 2013 If anyone has a pic please post it up. It doesn't show up in the parts manual.... Thanks! Link to comment Share on other sites More sharing options...
1989 Eliminator Posted August 20, 2013 Author Share Posted August 20, 2013 There is a o-ring but I don't think that it seals for vaccum. I thought it was more of a seal to keep oil/dust/etc. out of the master and booster. Link to comment Share on other sites More sharing options...
ggcnash Posted January 30, 2014 Share Posted January 30, 2014 Hi the spacer plate you guys are referring to would this be on a 96 xj stock if you found one at the yard,or is this something that you have to fab just to make figment issues better for our MJ's Link to comment Share on other sites More sharing options...
HOrnbrod Posted January 30, 2014 Share Posted January 30, 2014 Yes, all the 95 and 96 models I looked at had the spacer plate. Link to comment Share on other sites More sharing options...
mvusse Posted January 31, 2014 Share Posted January 31, 2014 Unless it is white foam, I did not notice a spacer plate on the 96 booster I swapped into Wilbur. But the parts vehicle was a late 96 and already had the 97 dash and engine harnesses. Did the 97 and up have a spacer? If not, would it be possible that the late 96s also don't have one? FWIW, the new booster works fine, but I swapped the 96 pedal assembly in with it. Link to comment Share on other sites More sharing options...
1989 Eliminator Posted January 31, 2014 Author Share Posted January 31, 2014 I didnt even use a spacer with my new 96 xj booster and my pedal position is just fine. Link to comment Share on other sites More sharing options...

86 mj Posted June 8, 2014 Share Posted June 8, 2014 i know this a old post but the best info on here was about the brake lights not working thanks for adding that it saved me from pulling everything out so thanks for that , i was going nuts...... best brakes i have had in two years ......duct tape who knew Link to comment Share on other sites More sharing options...
Incommando Posted June 14, 2014 Share Posted June 14, 2014 Something must have gone wrong on my install. I did no modifications for the brake light switch and it works perfectly. This thing stops so much better now. Link to comment Share on other sites More sharing options...
1989 Eliminator Posted June 14, 2014 Author Share Posted June 14, 2014 The reason for the modification is because I ground a little too much down on the new booster rod. If too much is ground down then the spring in the switch will not activate. If not enough is ground down then the spring is always compressed and stays on.

Incommando Posted July 8, 2014 Share Posted July 8, 2014 I missed that in reading through this. Yes it was the '91. And again: this is by far the greatest upgrade I have done in terms of safety. Link to comment Share on other sites More sharing options...
Jeep Driver Posted August 11, 2014 Share Posted August 11, 2014 Alright you guys, I did the swap today, I pulled one off a 97 ZJ. Actually I pulled two to get the extra spacer and two were unnecessary. Oh yeah, I got brakes alright, but now my peddle is low, it's now even with my gas peddle. Besides cutting and welding on a new end (off original booster) is there any other solution? Link to comment Share on other sites More sharing options...
mvusse Posted August 11, 2014 Share Posted August 11, 2014 Swap the 97 brake pedal assembly in along with the booster. Link to comment Share on other sites More sharing options...

1989 Eliminator Posted August 11, 2014 Author Share Posted August 11, 2014 To me that looks like someone cut the rod and threaded both ends of the cutoff Link to comment Share on other sites More sharing options...
MuddFoot Posted November 8, 2014 Share Posted November 8, 2014 if you get the lines from the jy when you pull the bb and mc do you still have to make new lines to connect to the mj proportioning valve??? Link to comment Share on other sites More sharing options...
1989 Eliminator Posted November 17, 2014 Author Share Posted November 17, 2014 Yes because lines from the jy will have only english or metric fittings on both sides. The lines you need will have an english fitting on one side and metric on the other. Link to comment Share on other sites More sharing options...
Parker Posted December 5, 2014 Share Posted December 5, 2014 Yes because lines from the jy will have only english or metric fittings on both sides.
