On my'48 Merc car, have tried differant lining material to get the good braking I have on my '48 Ford. Latest is woven linings which work slightly better than the hard material of others. All types stop the car but with a ton of pedal pressure. Drums are only .015 over. Nice firm pedal 3" off floor after pressure bleeding. Beveled tops of linings. With drums only slightly over 12", can't imagine arcing linings, even if were available. Just have to wear them in?

bo8109b - I have a '47 and have the same issue with new front shoes. Even after ordering a new set machined to the exact dimensions of my original drums the braking was weaker at first and gradually improved as the new shoes seated. My recommendation is to keep them adjusted and simply wear them in as you stated and try not to overheat/glaze them early in the process. After a few hundred miles mine ultimately perform as intended and I perceive will lock the wheels if needed after wear-in. Others have previously advised a break-in process that works for them - perhaps someone will chime in with their thoughts. For me, simply driving the car carefully and patiently with modest braking and adjusting the brakes when necessary has done the trick. Btw - arcing of linings is available if you wish to go that route, as is having shoes fitted with organic materials to the dimensions of your drums. Check out Brakes, Materials & Parts in Fort Wayne, IN. Also, I do not find it surprising you are having this problem with drums that are only 0.015" over. Just finished helping a colleague with a 53 Ford that is 0.012" over and the brake pressure required to effectively stop the car with new shoes is initially quite heavy.
