- Here’s what I did to fix my leaking hydraulic brake booster in my 1990 E32 750iL. It was leaking at the front cup seal and it was obvious that the old seal was very fatigued compared to the new one.
This is the guide is used:

Hope this video helps someone with a similar issue!
How did you get that grubscrew on the bottom of the Booster out? I try to fix the same Problem and Im stuck on this problem. Is there used to be an Allenkey in the middle of the Screwhead? mine is circular... FYI Some guys at the "7-forum" wrote the black plastic (bakelit) some times swole a bit and cause a clamp of the shaft an stuck breaks, im gonna file a bit the hole, if i get this "klump" (sry german) out.
If I recall correctly, it wasn’t installed super tight - I was able to break it loose by turning it with a small pair of pliers and then reinstalling just by hand and then finally tightening with pliers. There’s no conventional socket or Allen that goes in or over it. The little mirror helps!
at 6.42..do u kno the size of the o ring?..
I don’t remember, but look at the link I posted in the description, it has the part number for what you need and then you can get the size from there
@@leojt9423 .,..tqvm...but it will leak for awhile after replacing that o ring rite?...takes a while before it will stop rite?...
@@karinkatt7893 Mine kept leaking immediately after replacing it - I had to pump the brake pedal a few times to get it to seat! After that it was all good!!!
@@leojt9423 ...well...still leak abit as yours...will see in few days ...after few pumps during driving....hope the o ring will expand and fit nicely ..as if season it a bit for tat right fitt....
the same problem in mine 750il...
Now you just have to dump another $139.00 for the daytime relay to fix the side-marker tail-light issue.
Right!? At least that one’s easily replaced haha.
Nice. Doesn't look like a fun job.
Not as bad as I thought - glad I didn’t have to pull the booster out all together.
