Parking brake adjuster thing

[Jozi]

On the parking brake adjuster theres a little loght gauge metal clip of some sorts, its prob to stop the adjuster from unwinding. Is this little thing necessary? Mine have all but nearly disolved when i treated them for rust and are no longer of any good. It makes up part no 7 in this image http://ills.bmwfans.info/351.png

Can just about see it here


But from looking at google images it looks like its not used on other models.

Yes, that's to stop the toothed wheel unwinding itself. Without it, the mechanism will just shake itself loose within a matter of miles.

It cant really go anywhere though, its all sort of very snug. From looking at google images a lot of the pics dont have it and ive been told the compacts didnt have ot either?

It's not shown in the E30 ETK either.

I think its part of the adjuster and comes as a whole unit, mine are perfect other than the retainer thing
