My 48 convertible has suddenly started to pull hard to the right when I apply the brakes. I pulled both drums and do not see any obvious problem (leaks, etc.) The wear on the aft shoe on the right brake is less than the front. The left brake doesn't seem to indicate this pattern. Before I go any further is there a common, known problem that causes this kind of pull. In the past couple of years I have replaced all the steering linkage end joints and king pins. .

If the wear has reached a rivet or a wear pattern on the drum or backing plate, that will interrupt the full braking of that shoe. The wording of your post seems to indicate only two of the four brakes, so perhaps you didn't examine all four? In any case, self adjusting brakes wasn't one of Fords ideas in the forties, so a full, all-out brake inspection/adjustment day should be high on your list of things to do during the Corona lockdown.

The fact that it suddenly started doing this leads me more to a bad wheel cylinder and / or hose on that side. One or both not allowing the fluid to return. I assume the return spring is intact on the right side? Tire pressure good on the right side?

If it pulls to the right you should look at the left wheel cylinder. Sounds like it may not be working and only the right brake is functioning. Put the drums back on and have someone step on the brake pedal and try to turn the drums If you can turn the left and not the right you have found the problem.

HI depending how old the brake parts are, you could consider rebuilding both front wheel cylinders or REPLACE if have PITS inside, with NEW USA made parts, relining the shoes is also a options and repacking the front bearings ALSO replacing the front rubbers hoses would be a good thing also at the time, I have seen these collapse on the inside, believe it or not, causing brake pull problems and maybe the center rubber hose also my 2 cents 1937Ragtopman

The likely cause is a bad brake hose on the left front side. Brake fluid eats rubber, and the inside of the hose collapses.

I replaced the wheel cylinder and hose with new parts, on the left side. Still get pull to the right, although after a number of firm stops the pull lessens and goes away. Have bled the fronts (the left a number of times) with no effect. Aldo adjusted both fronts (they were pretty good in this regard). My sense is that warming the brakes up reduces and eliminates the pull. Anyone got any ideas?

Yes, your "warming the brakes up" causes brake fade on the most effective shoe. Doing one thing at a time, hoping to get lucky doesn't cut it. They'll never be equalized until you do right by all four wheels. Do what you'd expect a good brake shop to do. Pull all four drums, inspect & refurbish as indicated.

HI Brake pull old timers used Bon Ami pot scrubber, powder on the brakes., this will clean the drums and shoes, I worked for a car dealer and if we had a problem this was a quick fix. for certain applications, never had any issues doing this, we used a squeeze bulb, like the one you add water to the battery, this is good for a car that sits for long periods , you just spray it in a hole,and rotate the wheel only problem is that the V8 brakes it is hard to get on the brakes with the drums on, but the best way is to do the brakes , you have to do both sides to make it equal . hope this helps,37Ragtopman
