Squealing Brakes

[Major Softie]

Honest, I was not trying to push any buttons, but just clear up something you had said about brake pads which I felt was false. Like I said, I've been trying to talk about brake parts.

As for the rest, I would only like to clear up a couple things. I did not say anything about companies having outside ratings firms make up standards, or do anything else. I don't know what I might have said that you understood that way, but I neither thought nor said that. I did not say anything about the heat transfer into the piston comment because I was not certain that was wrong, although it didn't sound right to me either, so I was suspicious that it was wrong (for exactly the reasons you mention). Sorry if that made it seem like I was singling you out while letting others comments stand unquestioned.

I'm fine. I'm likely just ragging it. I got a bit miffed watching everyone kill the guy over his tires, then when I am upset, I start typping faster and deleting and making shit a jumble-f*ck and then it's worthless.

The ceramics, while I am not 100% certain I do believe to be the stuff that had no safety data that the Asians were all moving to and the US market poo-pooed it, considering they had just left the asbestos market and were in the middle of a giant mess with metallic compounds; tearing things up, corroding, or squealing. Potassium Hexatitinate and Potassium Octatitinate. It was, and I quote, "The greatest thing since asbestos..." I've seen some of it sense then and it appears to be far less harsh (does not have the porcupine prick-lies of metal poking you - so I hope that means it does not rip cast iron rotors to shreds.) And while it looks like it is super hard, it's not as hard as it appears. Besides some of that is an illusion as pads are made like diamonds under extreme heat and pressure. Anywho...

Fr the record the organics I installed personally on my '53 when the metallics would not even dream of stopping the car, are still faithfully on there and that was... 17 years ago.

The biggest reason ceramics are becoming popular with all the luxury cars is that the dust isn't as noticeable and doesn't stick to the wheels and ugly-up the $1000 apiece wheels on your $100k car. I didn't know about the health questions. I'm sure they'll figure it out without killing more than 10,000 or so.

Think I've solved my squeal problem. Replaced the OEM pads with EBC pads. Quiet as a mouse. The OEM pads would be quiet and then would squeal loud, then softly, etc. etc. etc. Got a great deal on EBC HH pads and put them on. Much better.

On the brakes on my '78 R100s there are some dumb little hairpin springs that, if they are not springy from old age or rust, result in weird noises from the shoes.
Bevel edges is ALWAYS helpful on any brake shoes. They used to come this way (40 years ago) but probably ditched from production in the interest of economy.

Good deal. Wonder what the properties "really were" on the OEM's? - [or became] or for that matter the new ones. Surely be far more inclined to think the new ones, being both new and A) Not being on the bike for "X" long and B) Not all products are what they are cracked up to be specification-wise applies to either product.

Everyone can just be glad that the squeal is gone. When all is is functioning properly, the pads are all that is left which is something I've never disputed.

OEM brake pads then will be very different from OEM pads now, a slight matter of no asbestos!

Absolutely - take that one as a given...

I managed to score a very decent dual brembo front brake setup recently. I took them apart the other night.
The pads were Textar (oem brand and still beefy).
The seals were in good nick and mostly well protected by the copper grease.




The pistons looked almost new...not a mark on them.

That copper coloured stuff is touted as reducing brake squeal too. It's tenacious like a bush oyster from a smoker!

I hope it's tenacious because there sure is a lot of it!
