Brake squealing

[yeuporsch]

Alright, my brakes squeal like cats-in-heat. Very loud meowing sound each time I brake. What have you guys try that work? The pads are still good. Thanks.

There is a liquid that you can oput on the back of the pads....but some pads like Pagid Orange just do that....

The four reasons I like "MetalMasters":
1) Good grip (for a street pad)
2) Low dust
3) Very little noise (i.e. no squeal)
4) Reasonable price

Like Mike said, "some pads just do that".

Does this mean that I have to remove the pads to put this on?

have your calipers been worked on recently? if so, did you/they check the pistons for that 20 degree angle measurement? i think this is to prevent squealing too. (that is what i just read)

Also, chamfering the edges of the pads seems to stop the squealing while the pads seat. Beware the dust, it is lethal to you. Take breathing precautions, bevel the edges and use the goo on the back of the pads.

Ditto to what unfixed asks here. scphelps1 had the same problem on his Euro 930 and the pistons weren't positioned correctly.

He was behind me for a number of miles on our last fun run and I heard his brakes screech the entire time. Happy to report that the problem with his brakes is corrected.

What year and model (911 or Turbo) is your car? Are your brakes stock?

Do a search...I've posted a number of times of various things to try...more chance of success, though, on 2 piston calipers rather than 4 piston.
PS- don't use the goop....tends to pull out the dust seals when it's time to replace the pads, use the stick-on pads that go on ther backside of the brake pads per my posts.

It's a '72 911t with stock brake.

What Wil said. You will find that, when you go to put the pads back in, you will have a tighter fit. Try to move the caliper puck in just a bit with the leverage of a screwdriver against the metal of the puck NOT the rubber seal.

You have to be sure the cutout on the puck is positioned to face the oncoming rotor. If it is not then you will continue to have problems.
