well, i finally got off my lazy ass and searched for the reason why my rear brake no workie workie. well, i thought i blew the rubber hose from the master cylinder to the reservoir. well, that's not it. i felt around the bottom of the res and found a hole. looks like there was a plug in it. i'm going to take it apart tonight or tomorrow, but has anyone ever had this happen to them? anyone know how much a new res would cost? if it's expensive, i'm just going to fill the hole with resin or something.
