[W126 Coupe] The Temperature! (and other stuff)

[dolans1 at verizon.net]

Attila seems to have the only answer so far by grinding the tabs an 1/8 inch at 35 degrees. Mine squeal so bad after new brakes all around that i am ready to park it for good...

>Re the brakes: You're using metal masters and stock rotors right? And you put anti-squeal paste (I remember Jonathan saying the MB anti-squeal paste is good) on the back of the pads, and then the shims on the back of that? Did you then bed the pads in properly? To see what I mean by properly, check out David Zeckhausen's instructions at http://www.zeckhausen.com/ (they're on the technical section of the website). If they still squeal...well I dunno.

>OK, I abused several folks last winter when it was -22 degrees and blizzard conditions in the northeast. Now it's your turn. It's still officially Spring here in Las Vegas and we got to 105 degrees today. It's the third day in a row for 100+ readings and we have maybe three days more of 100+ readings. Today was great for me though, I worked at home and never left the air conditioning. I did verify that the new a/c duct I had run into the garage made a difference though - with an insulated garage door and the a/c vent only partially open, it did get to 90 in there, fifteen degrees below the outside air.

>The NoiseFree brake compound I tried on the SEC rear brakes isn't much better than the Permatex or CRC anti-squeal compound. I bought a set of PBR semi-metallic rear brake pads for the SEC and they squealed like mad on there. I put on a thin coat of Permatex on the pads and shims, then a thicker coat on the pads and shims, then took off the shims and put on a fairly thick coat of Permatex, but it was still noisy. I tried the orange CRC anti-squeal compound with and without shims, but no change. I heard about NoiseFree, that it was "industrial strength" anti-squeal, but it was not much better and the brakes are still noisy. The NoiseFree guy said that the lip on the outside of the rear rotors was a part of the problem, then said the ridge on the inside was part of the problem after I told him that I had ground off the outer lip and put on a nice layer his compound to no avail.
