i've searched everywhere on the jalopyjournal, and other forums as well, and i'm at a loss. i have a disc/drum setup on my f1 (with a malibu front stub). late this fall i had noticed some leaking around the master cylinder, so much in fact that it was starting to bubble up the paint on my inner fenders. so i kept adding to my MC until i could get to it. i noticed that only the front reservoir would get low, and sure as hell one day it got too low. So i had run the front half of the MC dry but was replacing the calipers anyway so i did that, then bench-bled (in the truck) the front reservoir just to get the air out but did not see any. so here's where i'm at; with new calipers and brake hoses, i've tried gravity bleeding the system, tried the two person method, it seems like no matter what, i need to pump the brakes twice to get them to stop. it never takes more then two but almost always does. also, this may be related or not, but my MC cap is leaking (which is where all the fluid on my inner fenders was coming from), but nothing else is. all the lines are fine but the cap seems to be leaking almost profusely. this really baffles me since the brakes were working great all summer. the only difference between then and now would be that i've switched camshafts to a much more mellow grind, so it should supply more vacume but i'm not even sure that would have anything to do with my situation. any help would be great!
