I know the two are different which is why I would prefer to keep the one that is in perfect working condition on there. I just want the benefits of the dual diaphragm booster. Everything I have read states that the booster is the upgrade not really the master cylinder although I might have missed something. If I have missed something feel free to let me know.You'll need master cylinder as well, regardless of what dual diaphragm brake booster you use. The 95-01 XJ master cylinder is much different than the 90-94. Ports are metric bubble, so you'll need new lines. I got premade ones with the metric bubble fittings and flared them for the standard fittings. Worth every bit of hassle.
Plenty of write ups already out there. But everyone I have come across involves changing the master cylinder along with the booster. I am just being lazy and cheap and don’t want to replace the master cylinder I have now unless I have to.Do a write up I'm doing this soon
Thanks for the advice, but I am buying new. Got burnt on the first used setup I bought when I discovered the the booster was full of fluid after I already had it at home. Secondly the junk yards in my area want a small fortune for parts. So if I need to replace lines and fittings, I will be making my own.i would recomend going to a junkyard and pulling the lines and prop valve off of the required donor vechile, as well as the spacer plate under the booster. simplfies the whole install greatly. just be cafe, on the rear port of the propvalve there is a dummy cap used on abs models, this cap needs to be removed and replaced with a non abs model one to allow for the second front line to connect to the valve.
I swapped my 94 abs to 96 non-abs, but the doner was abs. not relizing the valve i had to return to said jy and fetch the missing cap.
simplied teh install greatly, since the lines out off the valve are sae not metric
Gotcha. I will have to call and see if they will sell them separately.not booster or master, i wouldn't trust a jy unit. just simply the lines and valve and bracekt. nothing can go wrong with those parts. saved me a huge head ache making by not having to make the metric lines, for which i don't have the tool to do so. i have sae.
I know they look different and I know they have different size fittings. I also know the bore is the same as posted earlier in this thread and I have also verified from a couple other people. I just don’t know why the 92 mc won’t work on the 95 booster. Jim, why won’t they work together? I am not doubting you, just asking a question. Thanks in advance.As I said above, you have no choice but to change the master cylinder. I have personally done this swap and am 100% certain of it. Use rockauto.com to pull up pictures of the master cylinder and power brake booster from both years and it will be obvious that the are not the same.
