What M/C for a 4x4???

[b454rat]

I swapped in a front axle with discs brakes in my 62 Burban, which of course had drums front and rear. I need a master cylinder that will work with the disc/drum, but not finding much. The M/C on it now has the the clutch slave cylinder on it, so I'm going to have to get a seperate one for the clutch. Did anybody do this swap before?? What did you use, difficulty rating, etc. It drives now, but scary with one wheel brakes, and really want to get this going.....

Hi there,
I went through this process with my Suburban. You can go a few different routes. You can use an adjustable proportioning valve and literally dial in your brakes, front and rear. But, If you just put in a master cylinder with no proportioning valve or booster then that's part of the problem. With disk brakes you will want to have both.
The other route you can go is to figure out the weight of your truck and then head down to the junkyard. Find a Chevy truck with your trucks weight and pull verything you can get your hands on (from the firewall down to the breaklines). Before you head out with your brake stuff, measure the distance of the pushrod, between the pedal and the back of the booster. You will want to get as close to that with your set-up as possible.
There was a single M/C on Ebay just the other day. I,m not sure if anyone bid on it, but it started at $9.95.
The most difficult part for me was getting the perfect position for the booster/master cylinder on the firewall.

Good Luck!

I have a buddy with a junkyard and all kinds of trucks in there. I think Im gonna convert to power brakes and use the set-up that you mentioned. Gonna use the slave cylinder off a newer truck and mount it on the firewall somewhere. I was hoping there would be an easier way to do it, but I guess there isn't. Thanks for the info.
