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)
