78 Big 10

[76shuvlinoff]

Hello, been a lurker here for a while. Yesterday a project followed me home.

I found a 78 Big 10, 6 cyl, manual trans on the floor, looks like it's all original with 24,008 miles. Needs some cosmetic love but for the most part it's a solid cream puff. I test drove it without issue but when unloading it at home the brake pedal went to the floor (power brakes). The brake light on the dash is on, I found the rear reservoir empty. Filling it did not solve the problem. I need to get it into the barn for a real look but I don't see fluid being sprayed around underneath or at the wheels yet.

With the engine running the pedal will hesitate but go to the floor every time. With the engine off it feels like it builds pressure and holds.

I've worked on a lot of new and old bikes over my life, I can spin a wrench but this is my first Square.
