Metal seal collar that sits just inside the drive flange on front drum brakes, 997 and 998 Cooper discs only. Use one (1) per side.

If you have a drum brake Classic Mini and cannot understand why you can not ever seem to get or keep the front wheel bearing tight it could be this small spacer is the problem. The spacer fits on the rear of the drive flange and serves as the thrust surface for the bearing. If this is worn or has a goove on it- the bearing will never fit tight!
