67 Master Brake Cylinder / Drum Brakes

Hi ya'll.

On a 67 - 4 wheel drum brake master cylinder, their is a front "well" and a back "well." Which one goes to the front brakes and which goes to the back brakes?

I have a slow drain of fluid in the back well (next to the firewall) and was trying to figure out where to look.

Thank you,

follow the line from the rear of the master cyl to the distribution block, and see whether it goes to the end with the front brake lines or the end with the rear brake line.

The back well next to the firewall should be your front brakes.

It's common for the master to leak at the rear if it's worn.....You could either rebuild yours or purchase a new or reman master

Re: 67 Master Brake Cylinder / Drum Brakes

On my 67 the front well is for the front brakes and the rear well next to the firewall is for the rear brakes. There are two lines comeing from the master cylinder on the left side.
The front master cylinder line goes straight down to the left side of the distribution block. Then that fluid or pressure comes out the front of the block to the left front brake and a line comeing from the right side of the block goes to the right front brake.
The rear master cylinder line (the one closest to the firewall) goes down and around into the rear of the distribution block and that fluid or pressure comes out of the block on the left side and that goes to the rear brakes.
If your getting any leaking out the back of the master cylinder it needs to be corrected as soon as possible because most of the time that fluid is leaking down the inside of your firewall and into or under your carpet.
