Does anyone know what size the rubber cup in a Birel master cylinder is? I had my master cylinder apart once for cleaning but can't remember. I know the caliper is 1 1/4". I think it was either 7/8 or 1". Thanks.

There are two types and one will need to measure the inner bore to be sure. Only in the recent years has Free Line put the part number on the side of the master cylinder. In the 1995-2003 years they did not post the numbers.

I went ahead & rebuilt it. It has a 7/8" cup in it. Thanks.
