99 Brake Booster Swap Questions!

[Dirteatr717]

I searched through 3 pages of stuff and didnt really find out what I exactly needed to know. I got a brake booster and master cylinder from a buddy that was parting out a 99 XJ. What all is entailed to swap it with the old crap in my 89?

If you can get the brake peddle assembly it will be 90% bolt in. You will need to fabricate a short bracket to tie the top of the peddle assembly to the original mount behind the dash.

Darn the XJ is long gone, I haven't looked at the differences but my trucks manual also..

The '95 - '96 XJ boosters are more ideal for this swap since the booster's rod length is pretty much spot on.  The '97 - '01s are longer, thus the reason for wanting/needing the pedal assembly.  The master cylinders are the same, however, for all '95 - '01s.  See if you can get your hands on a '95 - '96 booster and sell or trade yours.

Yeah, besides the pedal height being higher its a straight bolt in swap, You also will probably need to make the 2 short brake lines as well between the master cyl. and the distribution block.

I got parts from a 96, I think dual dia. bosoter/master and also got the matching brake pedal. So no trial and error grinding and fitting the new rod, etc.

As far as the lines, you could probably do some sort of adapter/union. I work at carquest so I figure I can test fit and figure all that out before I swap in mine.
