Abstract
A brake master cylinder includes a shiftable seal that provides an apparatus for maximizing compensation fluid flow during minimal fluid draw conditions such as occur through automatic traction control brake intervention type operation. The shiftable seal moves forward to compress a low load spring during fluid draw from the master cylinder's high pressure chamber to open a compensation flow path between the seal and the piston.
