I had the front shoes on my 51 relined with FF brake material by Rochester Clutch and Brake who caters to the vintage guys and has a good reputation.They told me it would be an improvement, but don't expect miracles if the brakes were in good shape to begin with.Had the shoes relined and ground to fit the NOS drums I stole off Ebay.The guy was right,they work fine but not all that much better than the generic shoes I got at the local parts store 6 years ago.No problem, the relining was only 25 bucks.
