Mini & Metro?
Turbo Mini Forums

Right

Went scrapies and got some back plates off a M reg Metro/100 they look like the later mini type ones just the adjusters are different is this the case? or are they really differnt?

My drums fit fine and they fit on the radius arms so i take it they are fine?

thanks Steve

Check to make sure the slave cylinder fits I have a funny feeling the locating pin is in the wrong won't line up.

Own the day

Oh right If mini one's don't work then ill use metro ones :)

the cylinders are sized to suit the master cylinder and car generally; you may need to do a bit more research to see if they suit your braking system

Ive got the braking Master cylinder the tower style not the tin can style and I'm sure its not a problem as Ill be running 4 pots on the front

If you fit metro ones, they may be to kean locking the back wheels up to soon, if that happens you would have to fit an adjustable regulator to set them up correctly.. Alan

Would it really that bad then? Ive read online the cylinders are same size as Mini cooper S and 84 onwards and shoes are same size its just they are got different adjusters but didn't think it really make that happen to be fair. Steve

If they are the same size as you say, then maybe they will be OK.. Alan
