Chas,
Brake squeal is caused by vibrations producing sound much like a tuning fork after it has been struck. You need to find an effective way to dampen the vibration, thus stopping the "tuning fork" effect. The silicone helps absorb the vibrations. Maybe you should try putting the silcone on the caliper in long pencil-sized strips where it won't show and across the top of edge of the pad where the cotter pin goes through. Doing that SHOULD dampen the vibrations and stop the squeal.

Good Luck,

Rob

My squeal is on it's way back
 
Chas, I hate to say this, but my squeal is on it's way back. Not garbage truck loud yet but you can hear it.

Men,
Silicone high on the list.
Chuck, sorry to see you also suffer, I'm Fricken Garbage Truck LOUD! - except for average street driving.
Let's all try to threaten Bob and see if we get an "elegant" engineering solution!

ERA Chas 06-26-2005 06:03 PM

Bob,
 
Can you report the status of the testing you mentioned on 5-31?
If you require a different " test" customer,
I'm available for immediate results. :)

ERA Chas 06-30-2005 04:11 PM

Bob,
 
Appreciate anything you can tell us about any brake testing progress. If none, please let us know. I for one, stiill have serious noise problem.
Cow,
Done that early on, no help thanks.

BOB,
 
I have been waiting since your post of 5-31 to address my brake noise problem with the other suggested solutions on this thread and some other pads donated by a friend.
I've limited the use of the car because of the problem, but this much time suggests I should probably proceed towards a fix.
I just hate to go through the work without word from you on any R & D you've done. Especially if you found a cure.
Anything you care to report, either way, beforehand?
Thanks,

I'm sorry things have been going slowly. My "mule" guy has been very busy and not able to put significant miles on the new pieces. I don't want to make recommendations without good data...

ERA Chas 07-08-2005 03:48 PM

BOB,
 
Since you have developed pieces and are testing them, I prefer to wait a little longer.
I just hope not another month. Would you post here the results or whether it will be a protracted time period?
Thanks for the word.

ERA Chas 07-25-2005 05:06 PM

Bob,
 
How about now, any results or news yet?

Latest Update

There's good and bad news. The pads we tested eventually started making noise. :CRY:

However, we will soon start testing a new Wilwood pad (Type BP - it hasn't been publicly released yet) which promises to be a better choice for dual use than Wilwood's street pads. I've also got some Hawk pads coming.

Wish us luck. :rolleyes:

Started noticing the sq....llll! also but figured I'd just stop using the brakes. Looking forward to seeing another solution.

ERA Chas 07-26-2005 04:22 PM

GOOD FRICKEN LUCK
 
:D Thanks Bob!:D

A couple of solutions that worked for me
 
I thought sure I posted my results earlier but evidently they are gone now.

I solved this problem twice, I have the sierra callipers.

I switched to Hawk pads part number HB101.F.800 and the squeal went away.

Then when I was preparing for an open track event in my car I put on the original hard pads. After working them hard on the track for a day they didn't sqeal anymore either!

Go figure, Hope this helps.

Chuck
