Doing a swap to a dual master, but keeping my drum brakes. Here is the problem. The brake pedal is a pull and push (see picture)http://www.flickr.com/photos/old_betsy/5294667154/in/set-72157625553190073/ I need a dual M/C whith the port on the opposite side of the railing. I found some that would fit but they are only 1 in. bore. I also read that the dual M/C reservoir for drum brakes suppose to be the same size, is that correct?. Does it matter witch side goes to the front or back. Where do I put the Hydrovac?.
