drum shoes are for emergency brake
and calipers are for regular brakes.
Anyway, I found a electrical junction box that had some sheet metal wings and modified its hole to accommodate the shoe hold down pins. It was a real time consuming ordeal not only in making them, but find the metal, then they would not stay in place. Finally, I got the pins to hold in them. I saved the onwer allot of money in pulling the bearings ect. BTW this bmw has corrosion. Sucks!! this is the reason why the splash plate has corrosion. Now the brake line is leaking. Corrosion has eaten it over its life and working on that brake has weaken it where it leaks. None of the lines can come off even with heat. I told the onwer if you want to flip cars, PLEASE do not buy one with corrosion it will eat you alive to in the terms of $$.
