I got a 71 Beetle that doesnt stop so good. The peddle goes all the way to the floor. I checked the brake fluid, master cylander and lines dont leak, andblead the brakes. The only thing i can think about is the shoes are bad, but they dont look like it. what is the measurment for the shoe wear? any help is appreciated

 

does your pedal feel spongy or mushy?
you may have a bad master cylinder orbad wheel cylinder

 

If nothing is leaking, and the cylinder is holding up, and maintaining steady fluid, than the calipers are prolly leaking behind the piston, or somehow air is getting in the system. When you bled the brakes, was there alot of air? I would make sure the master cylinder has alot of fluid, then bleed them again. Feel to see if there's a lip on the edge of the rotor, if there is than you just need to rotors and/or brake pads. Stay in touch..
