We are brake specialists offering both stainless steel or brass liners to Master cylinders affording better than original "lifetime" solutions with NO PITTING EVER to the bores.  Our re-builders are second to none and are where many of the "others" actually turn to for servicing of these European components.  "If you find it cheaper somewhere else simply tell me where and how much and I will do all I can to meet or beat that price!"  This of course is based upon equal quality and retail or retail "sale" prices.
