Shake, rattle and roll

[Steve 944T]

I have been lurking in these forums for a while now so thought I had better say hello. I have recently become the proud owner of a beautiful black 944 Turbo S, which has replaced an Impreza RB5. I see a few familiar names from scoobynet (I hope I dont get an instant ban for mentioning that name!!!)
I am so far delighted with my new beastie but have an annoying rattle from the driver's side rear. It is irregular and doesnt relate to road speed. I am pretty sure it is from the brakes as the rattle stops when I put my foot on the brake. A Porsche pre-inspection did not mention any rattles, but did point out that the calipers needed a refurb, which was done. So, are there any known common problems in this area? There is nothing obviously loose and it doesnt sound as though anything is about to fall off. I realize that a rattle is not the easiest thing to diagnose over the internet but any suggestions will be gratefully received.

Well, seeing as no one else has said it yet, welcome to the forum! Watch out for Domster, he'll try to convince you to buy a 964RS! (although you may have gathered that for yourself already!)

Have you got any pictures of your 944? I'd quite like to see a decent pic of a Turbo S (they seem to be a rare beast)

Welcome from a fellow scoobynet'er.

Can't picture 944T rear brakes in my head but I 'think' its simliar to others in that they have little sticky backed sqeal shims that need to be replaced at same time as pads, so may need new ones and a bit of copper grease smeared around the place too.

Another thing to check is the stoneguard that is behind the brake disk. They are held on by three bolts and can rust away over the years so that they vibrate. I know this because one of mine does it at exactly 6100 rpm

First time I heard it I thought my gearbox was about to drop off You can snip the guard off, and then replace it next time you need rear disks

Buy a 964RS.

Oh, and Super Marv, the 944 Turbo S isn't as rare as a 968 Turbo S, which was mentioned on the forums earlier. They made something like 13 968 Turbo Ss, but the 944 Turbo S is just the 250bhp version they made from about 1989 onwards, IIRC. Fair few more about.

Thanks for the welcome and the tips. I really need to get rid of the rattle as it is driving me mad. Then I just need to cure the rattle from the hatch and all the rattles from the dash/door cards

Re the 964RS, I wouldnt need much persuasion to get one. However I went for a 944 as it is more practical for me than a 911, let alone an RS version. Maybe next year

And re the Turbo S, it was built in 1988 and as Domster says, is more or less the same as the 1989 onwards turbo, but the S is much better as it has an "S" badge on the back and does not have a sunroof

You are better off getting rid of these plates altogether as that way your brake will cool quicker (less fade and less chance of boil)
