[Healeys] Front brakes

[Kenny J]

Hey Guys, Looking for front brake help. I replaced both the pads and discs
about 2 1/2 years ago.  I used the anti-squeal adhesive strips.  The brake
squeal continued to get worse since the install.  About a month ago I replaced
the pads with a "better" pad.  When installing the new pads, I noticed the
anti squeal strips I installed 2 1/2 yrs ago were very deformed.  The new pads
advertised they would not squeal and looked to have some type of an anti
squeal strip already attached.  I installed the new pads and now (after a
month of use) the squeal is back.  Nearly every brake application there is an
extremely loud squeal.  It appears the harder I apply the brakes the quieter
the squeal.  I was looking at the front brake diagram in the Moss catalog.  I
noticed brake shims (part #582-900).  I compared that diagram to the one in my
shop manual which did not show any shims.  My car does not have those shims
installed.   I have two questions: 1) Will those shims help?2) Could the cause
be the calipers? Thanks Kenny '61 BT7
