I need urgently a set of break pads for a 1977 400A, let me know the best place to get them
It depends on which brake system you have. If you have a Bendix system, for the front pads use any BMW pad from this table that crosses to a Hawk HB206.565 such as a 79' 528i. Or, you can just use the Hawk pads as I do. For the other system, I forget who made it, you can get them from EuroSpares. http://www.racerpartswholesale.com/hawkapp2.htm
