Ive got a 1970 Buick Skylark, all original, with four-wheel drums. It just hit 70k miles, and i had to replace the shoes. The problem is, the front right drum keeps getting extremely hot and warps, causing surging, very loud noise, and makes the steering wheel shudder. Ive had to replace it twice already, and now finally the guy at the brakes shop tells me that its probably because the only pads available are metallic ones, and that they produce a hell of a lot of heat, because its such a heavy car (3,800 lbs). He told me i should get some asbestos ones, but i guess they are illegal. Where can i buy asbestos shoes and import them? Or is there any other way to fix this problem besides switching to disc? (i really dont want to spend the money on a whole new assembly) Thanks for your help!
