Master cylinder rebuild service

June 1, 2007

San Francisco, Ca.

Let me assist you in building a correct master cylinder for your Spridget upgrade from drum to disc brakes. When disc brakes were introduced on MKII Sprites and MKI MG Midgets, BMC changed the design of the master cylinder using 3/4" instead of 7/8" pistons.currently have 3/4" pistons 3/4" bore mastercylinders have not been available new for a number of years except in the case of a donor car. Now for the first time in years, these pistons are available. Working with an expert in the field, I can have your 7/8" master cylindedr sleeved to accept these pistons.

Available pre-drilled.
