My 57s brakes in terms of panic stop capability are terrrible. After viewing various blurbs about the subject, I'm thinking that the linings on my car are probably real cheapys. (by the previous owner) Can anyone recommend a better quality lining thats readily available? What about linings containing metallic particles ?  Would they tend to be noisy & eat the Drums?  I don't want to get into a Disc brake conversion at this time.. Any help appreciated.
