1970 F100 w/ small block 302 Drum brakes

I've bleeded my brakes twice but they still seem very loose. The thing is when the truck is off they harden up? New to all this just trying to do things myself. I nalso did notice a small drip coming from the Master Cylinder, maybe that could be it?? Any help would be awesome, thanks.

I'm assuming you have power brakes...

Ford had a reputation for having one finger power steering and a light brake pedal. Made driving easy.

Does the pedal sink to the floor? What happens when you're actually driving? How well does it stop?

I do have power brakes, and the pedal acts like it wants to work yet sinks to the floor. When driving, the brakes work but I have to apply so much foot pressure. They use to work great about a month ago then air got in the lines when the front resivor emptied out.

Then I do believe you have solved you're own problem.

Air in the lines. Keep bleeding them. The front reservoir runs the rear brakes.

If you're losing brake fluid from the system, it's going somewhere. You mentioned the MC leaking but not from where it's leaking.

At any rate, the fluid level shouldn't be dropping. Bleeding the brakes out on a leaking system won't make the problem go away until you have a sealed system.

One of the wheel cylinder links might have slipped off. This happened to me and produced the same symptoms, minus the leak.

I blew the rear hose and only had front brakes one time. Pedal feeling was horrible and the truck barely stopped.

Rear brakes do a lot.

Only Proper Preventive Maintenances when done these problems don't happen.

This is like waiting to only buy new tires when you run each one of them bald till you have a blowout. Yup got my moneys worth out of each of those tires.

I remember my brother always had 2-3 spares tires back in the day.

Then go to the junk yd and buy a few more good ones as needed, they were cheap an most came with mounted on a wheels that fit your car. 600x16 as, I remember a size that most ford had then.

One learns to control a vehicle while having tire blowouts though which was a good thing! if you look at it that way.
