This is my second post for the day. I just purchased a 63 C60. It runs and shifts good. The two speed also works as designed. However I have brake issues. I have searched the site for tips but wanted to throw out my specific issues to see if I can get some help in prioritizing the troubleshooting. First off, I have fluid in the master cylinder and no noticeable leaks from anything. The hydrovac mounted to the frame under the driver side looks to be newer. The brake pedal is stiff but will go to the floor and eventually slow the truck down. If moving slow it will lock up the right rear and takes several seconds to finally release. I'm not sure exactly what goes on in the hydrovac, but by looking at it, vacuum comes from the manifold, down to the hydrovac. Additional vacuum lines come off. One goes to a breather in the rear corner of the cab interior by the seat and the other goes to a manifold of some sorts and then back to the two speed rear. If the rear end works, I assume the hydrovac is getting pressure. I was thinking of replacing all of the brake hoses as a start (just need to find a source). What do you guys think?
