What would cause my brake pedal to get hard and no front brakes on my 56 Fairlane with all manual drum brakes? I tried a new master cylinder and new front shoes which were glazed. The pedal is still rock hard and no front brakes. Dave V

Did you try to bleed the fronts? Almost sounds like a blockage in the line somewhere.

Yes, I did bleed the front ones with a hand pump (syphon bleeder) and fluid flowed well. DaveV

Sounds like you might have a blockage in the master cylinder Carl

Just throwing this out there but are the wheel cylinders moving like they should?

Frozen cylinders was my thought also. Remove the drum and have someone push the brake pedal slowly and check for movement..

I had this problem on a Ford pickup after it sat over the winter, What was wrong with it is it had a ring of corrosion inside the Wheel cylinders
Causing them to only travel half the distance it took to apply the brakes! I don't know why the peddle gets hard when this happens but my truck elt like stepping on a rock!

Disconnect the front brake lines and slowly depress the brake pedal a little bit to make sure the master cylinder is pumping., If so, then pull the wheel cylinders and remove the cups to see if the plungers are stuck.

I also wondered about the wheel cylinders but don't understand why both would seize up at the same time. I did order them yesterday and will be installing them tomorrow (Sunday). Will post the results. Thanks for all the input. Dave V

I know you said you put a new master cylinder on but it sounds like the small bleed hole is plugged.There is two holes in the bottom of the reservoir,a large one in the rear and a smaller one just forward ,the large one lets fluid to the piston and the smaller one lets fluid return when you let off the brakes,I had the small one plug up with crud a couple years ago and it did exactly what yours is doing Carl

Carl,. you were correct on the bleed hole being plugged with some small rust particles. Took the MC apart cleaned it out and flushed the entire system. Works great now. Thanks for the input. Dave V

Sounds like buggered wheel cylinders.. and your linings could be undersize, push as hard as you like not much is going to happen.. Ask me how I know ...

Years ago I bought a 57 that done the same but it was froze up wheel cylinders and bad hoses and glad to hear it was a much simpler repair.
