Re: [DML] Re: Wanted: Completely different brake setup

[Christian Williams <delorean@xxxxxxxxxxxxx>]

Thank you for all the comments and ideas. I'll repsond to all the points,
because I still don't feel any closer to an answer.

David,
Yeah, I do seem to be in the vast minority of owners as far as brake noise
is concerned. I'm not racing the car and I only panic stop if there's a
need to (maybe twice since I've owned the car). I've never purchased any
brake components from anyone other than PJ Grady, Houston, or Garden
Grove. Point noted on the ventilated rotors, but at the same time, I
shouldn't be hearing these noises under normal driving conditions - but I
do. My car is a daily driver (thus the daily frustration). I just had the
rotors turned about two months ago, so they aren't rusted.

John,
The front brakes squeal when coming to a complete stop. There's no
grinding or chatter. The thing that drives me crazy about the parking
brake is that there is so little travel. If I get the pads to close, they
chirp as the high point of the rotor comes around. If I back it off to
where the chirping stops, the parking brake doesn't move enough to engage
the rotor when parking. Somehow, right now the parking brake will only
hold the car on a perfectly flat surface - yet I'm getting the chirps as
well.

Robert,
I've used PJ Grady brake pads as well. I've spoken with Rob on the phone
about the specific squealing problem and he sent me out his best pads.
This was probably a couple years ago. I don't know if the pads you speak
of are something new that he carries. I'll give him a call. SS brake lines
sound good. Squeaking and chirping aside, more braking power sounds like a
good upgrade.

Dave,
The fronts only squeal when braking to a stop and the rears chirp whenever
they want to (usually most frequent when turning right). Pulling up on the
parking brake changes the sound, so I'm sure it's the parking brake pads
rubbing. A stuck caliper would squeal all the time, correct?

William,
No shop has touched the wheel lugs since I've been on the latest warpath
to stop the noise. I always hand tighten. Also, while I was doing the rear
rotors, I couldn't really understand how overtightening the lugs could
warp the rotor. Can anyone shed some light on the physics of this?

Thanks everyone. Please keep the ideas coming. Maybe I'm overlooking
something. I know that most cars don't exhibit this excruciatingly
frustrating behaviour and I know that it "shouldn't" be happening, but it
is. From where I'm standing now, the only real hope seems to be a
completely different setup. But I'm hopeful. I'm a young owner and don't
have the experience that a lot of you on the list have. Hopefully I can
get this sorted out one way or the other.

-Christian
