Re: (ET) Bye bye brakes

And now for the bad news. The last time that I checked, Bill could no 
longer
get the thin steel washer that goes between the outer pad, and the caliper
pins. It usually disappears at the same time that the pad does. Just 
another
vote for updating to the steel caliper, although I must confess that I 
still
have the cast caliper on my E-20. I check the brake wear VERY frequently.
