[Healeys] Squealing Brakes

[Norman Nock]

    If you have squeaky brakes on a bicycle or a Austin Healey you need to
toe-in the brake pads, on a bicycle you can  tweak in the brake pad arms with
a wrench to give it toe- in .. you cant do that with your Healey but if you
look at the shim it shows how it should fit , this will give you a toe-in upon
application of the brakes ...The squeak comes from the worn rotor , a good
smooth rotor you should be able to draw a solid line across the rotor surface
, with a ball point pen , not a dotted line More info. is in A/H Magazine Jan
1994  or my Tech Talk book page 5         Norman Nock

Hi Bob,

Brake squeal is simply a high frequency vibration of the pad against the
piston. If this can be interrupted by a shim (usually but not always works).
Any sort of grease or other substance between the parts will dampen the
vibration. If shims don't stop the squeal, a high temp. silicone grease
smeared lightly between the parts will do it.

pads away from the direction of rotation of the rotor, but what's the theory
behind either?
