I have been rebuilding my front brake calipers. It seems that the brake fluid
and brake hoses were factory original in my car and it had been sitting about 2
years before I got it. Having cleaned all the junk out of the cylinders ( no
pitting fortunately), I have reassembled them, replaced the seals and re -
installed them only to find that there is a small recess on the disc side of
each piston and I should have oriented these correctly. The recesses are so
shallow that I didn't notice them. Both calipers are back on the car with the
pistons in random orientation. The manuals I have say "note how the recesses are
oriented & place back the same way." Can anyone tell me the purpose of these
recesses and should I redo the job - if so how are they oriented? Thanks.
