I don't kmow the purpose of these recesses, but the manuals I have 
show how they should be alligned relative to the caliper. I don't have 
my manuals here but I could look it up tonight.

You may be able to turn the pistons in the calipers by gripping the 
calipers from the inside so you don't damage the chromed surface.

I think the purpose of the recesses is to push the pads onto the disk 
at a slight angle to prevent squealing. Anybody else want to take a 

Dirk (and his MGB with correctly oriented recesses and no squealing)
