Question about brakes, review of in tach remote display

Brakes first -
My brakes had a squeal that sent shivers down my spine. I have 96 933 C2 Cab...when I came to a slow stop with the top down it was not bearable. I took it to the shop here in San Antonio and was told that the pads had 50% left on them, but that the dampeners needed to be replaced. They did this work and after I got the car back...same squeal. I called and reported this and was told that it is the way that I drive. I was told that I am usign the brakes too lightly and if I would hit them harder it won't happen. I actually tried this, but find that when I am almost stopped, I always let off the brakes to come to a smooth stop. I have not had this problem with my other 993, and I am sure I drove the same.
I was told by the shop that they could replace the pads, but if I keep driving this way it will happen again. Then, they mentioned that they could cut the rotors?
Have you heard any of this? Are these valid comments? The thing is that this shop, Jones Autowerks, is only a Porsche shop. They have a very good reputation in town, this is the first time I have had anything questionable from them....any help appreicated.
IN TACH RADAR DISPLAY -
Thanks to P-car.com I took my remote V-1 display and put it in an extra Tach I had laying around. I will say that it was pretty easy overall. However, the face and the plastic backing are much harder to cut through than I realized. When I put the guage back on and replaced the needle on the gauge, I took car to make sure it was seated at -250 RPM's After putting back together and puting in the car, the guage sits at 500 before power is turned on, where it jumps down to 0. From 0-1500 it is a little jerky, then it smooths out. In addition, I have a little light bleeding around the display at night and will need to take out and open up again to put a bead of epoxy around it.
The overall mechanics of the DIY are pretty easy, it is the small details that I am not as good at that have probably lead to my problems. Now that I have done it once, I may do it again using my other Tach. If I do, I will order a knew remote display and leave this one as (with Epoxy to block light). I figure now that I have done it I can do the next one better, then probably sell this one on Ebay. All in all - I would highly recommend this DIY to anyone who wants to use the V-1 as it is very nice to have it all line of sight.

Regarding your brakes - general consensus here is that the OE Porsche Textar pads and Porsche rotors give noise-free braking. I just replaced the original factory rotors/pads/anti-rattle spiders/sensors. Prior to doing this, the brakes never made a noise and stopped the car with authority.
Do you know what pads are on the car presently? Were the anti-rattle "spiders" used? Working on the brakes is actually super easy. You may wish to dig into this personally and get a feel for what's going on under your car.

I had terrible brake squeal until I replaced the pads with the OEM Textar pads. I ditched the spiders and smeared Lubro Moly LM 508 anti-seize compound on the back of the pads. No squeal since then, even under light breaking.

I think a previous thread reported that squealing was greatly reduced by blowing out the dust from the holes in the rotors with shop air.
My 95 has the original pads and rotors, and they are completely silent, no matter how gently I brake.

If you have OEM pads there is zero squealing. Try that first at a Porsche dealer or if you want to take a drive take it to my old mechanic Mike Callas of Rennsport in Sealy. Ask the dealer to ensure that the anti squeal tabs/ brake pad sensors are also inserted as some neglect to put them back ( they are a PITA to re-install)
I suspect that you may have some Pagids on or some really aggressive pad. With the Pagids the comment of braking harder is kind of valid, although these pads need heat to stop squealing which can only happen on the track realistically. My pagids squealed like pigs on the street. One thing is for sure that its not the way you drive...

What are the odds of not having a problem with multiple changes of the rotors and pads???
Furthermore in my 17 years of P-car ownership I never encountered squealing from standard factory equipped P-cars. I also don't know any other person on RL with a 993 that has that problem with everything and correctly installed. If you are the first person, then its a first or maybe your car is equipped differently? If you are 100% sure that your setup is 100% factory and 100% properly installed and you still have squealing, then I take my statement back and revise it to read " If you have OEM pads most likely you will have zero squealing".
So what is your story?

Even with professional mechanics, eliminating squeal is more of a trial and error process. There are all sorts of tiny variables in a 10 year old car that could allow enough free play for the high frequency vibration that makes squeal. I could probably fix the squeal by pulling everything apart again, taking solvent and brush to the inside of the calipers, replacing the spring plates, cleaning the caliper mounting faces to make sure everything is perfectly square, etc. But just slapping on some new factory pads and rotors won't guarantee quiet brakes.
