(oh its drum rear too)

master cylinder issue

cheers. Can i chuck a vr master cylinder in it being drum rear or?

air is getting in somewhere. no visible leaks or cracks? you can remove the master cylinder and get seal rebuild kits just like calipers. not sure about putting in a vr one but the 15/16ths and 1" master cylinder are interchangable and able to be fitted on drum and disc so i don't see why you couldn't use a vr one.
