'79 brake problems
I have a '79 F-150 and the brakes worked awesome, it could stop on a dime. It was sitting for a week, and when I went to start it to move it and had no brakes what so ever. Checked the master cylinder and it was dry. So I pressure washed the under body and topped of the brake fluid to look for a leak, but can't find one. The only thing I can think of is the master cylinder is shot, but the doesn't explain why I can't find the leak. I don't want to replace the whole brake system and find out it was something simply. Any ideas??
