Question about 67' dual master swamp
I've read the sticky about the swamp and some other threads.... But do have a question. I got a 67' dual master, gonna install into my 63.... It's pretty clear that my brake pushrod is going to work and won't have to worry about that, now after sourcing all the right Brass Adapters for the piping, but once that is all put together... I'm confused on which 2 of the ports are for which Brake lines.. The back port closest to the firewall is a 5/8s port... And the front is 9/16th.... I can see by eyeball on the pictures from other threads my ports are reversed, looks like the other MC they have got a 5/8s port on the front.... Maybe I am over thinking but I am going to attempt to do the swamp after work and be able to drive my truck the next day, so I want to be sure on the procedure... If anyone can help me I would greatly appreciate... Thanks a ton for reading!

Re: Question about 67' dual master swamp
Are you disc/drum or drum/drum?
For disc/drum, the larger port and reservoir go to the front brakes. K

Re: Question about 67' dual master swamp
Like Keith said, the larger port and/or reservoir go to the front brakes.
I used a '68 drum-drum cylinder on my '66. One port was 1/2", one was 9/16". I plumbed the larger port to the front brakes, and it works like a champ. No need to fool around with cylinders from other applications, or make this any more difficult than necessary. |
