ABSTRACT:
A diaphragm for a vented master cylinder reservoir which further includes means for opening the slit thereby assuring venting of the master cylinder reservoir is provided. The slit opening means are configured in such a manner that contact of the slit opening means with the master cylinder cap will cause the diaphragm to be stressed and to elastically deform, therefore assuring the opening of the venting slit.
