Hi. This has probably been discussed a thousand times but I am desperate so here goes...I have the original MMC on my elise and for months (since I purchased the car) all was fine. Then one day the squeal started and it has become pretty bad. I have since tried copper lube on the back of the pads, also a special brake squeal product and finally also shims. Now tried shims and copper lube. Still no good. Anyone out there with a solution that does not involve going to different discs?
