Hi, All Guru My front brake vibrates as I step on the brake pedal. Also, the brake don't feel grippy as before.I've have both my front discs skimmed about 2 months back and replace with new ferrodo high performance brake pad. Anyone can advise? If not, can I purchase the e46 330i front brake calliper and disc & modify & install to my e36? Any done it before? Is it possible?
