Hi, cant find any repair kit for my master cylinder, its a 1993 GC 4.0L with rear drums. Is there some XJ repairkit i can use?
Its ABS if that have something to say.

 

Buy a new master cylinder, they are cheap and easy to put on. Brakes arent something you want to skimp on I wouldnt think.

 

Like Xj88 said, master cylinders are easier and cheaper to replace rather than rebuild. You should be able to find a replacement easy. The only time you should rebuild is if the price is too high for a reman or it's a rarer vehicle.

 

Less than 30 bucks for a new master, bench bleed, install, bleed the system and be done. Or hunt all over for a rebuild kit, tear apart the old leaky piece of junk, find out you don't have the right hone, find huge pits in the bore, install the kit, it leaks worse than it did before, you find an extra part on the workbench, end up buying a new master anyway. Your choice.

 

ok, just to be sure its the MC thats leak. On the brake booster the paint bubbles arround the MC and in wide stripe all the way down on the booster. And when i "pop" the bubbles its wet inside, thats must be brake fluide, correct?
It dont loose any fluid when not in use, and it also seems that it loose more fluid if i have activated the ABS (if i remove the ABS relays and fuses it seems like it dont leaks as much).
Could someone help me find the correct MC that i need?
