I replaced the brake cylinder on the left rear and now it pulls to the left hard when braking. I have adjusted all the brakes but to no avail. Can a rear brake shoe cause it to pull left and if so, what could cause it?
Thanks for any advice you can give me to correct it. I bled all the air out of the lines because I thought air could cause it to pull.

Sounds like you should pull the rear drum again an recheck that you have assembeled all components correctly. Is wheel cylinder brand new repro or rebuilt original ? same as one you pulled out ? Brake fluid soaked linings ? Springs on shoes correct way around ? Shoes centered to drum ? You have to be very particular here. Only one way to do it.... the right way. IF in doubt check ford manual for the year of the brake modification, ie 1939-48. Original 34 had mechanical rod brakes. You could also pull off other rear drum and compare the assembly. Good luck, Kevin.

If it pulls hard left,(violently?) then the right hand front, is not working as well as the left.
If she swings gently but consistently to the left then I would go with a right rear not working properly.
FYI
Contamination of the linings can cause "grabbing"as well as weak function.

Mis matched lining material will cause uneven braking.

A hard pedal with travel,requires adjustment, while a spongy pedal requires bleeding.

As a rule of thumb I would suggest always doing the same to both sides of an axle, because(as in the case of the wheel cyl) the mate to the one you have replaced is probably on its last legs. if you do it well, you shouldn't have to open them again for a long time.
Cheers.

Make sure that the inside diameter of the new cylinder matches the old (and other side). While unusual, it does happen that you may have gotten the wrong size wheel cylinder.
