I thought that replacing my front pads had fixed this - but it's not the case and it's getting worse. Only does it under light / "normal" braking - heavy braking is fine. It's actually reached the point where it's a bit dangerous.

I am going to order new front discs next week - although I don't think mine are all that old. We'll see if that cures it.

NB - I haven't read through all the above posts, so apologies if I've repeated any!

1. I agree with Simon re 'warped' discs

2. Dave - could be tyres; was the car sitting unused for a while; could simply have 'dented' the tyres which take a couple of days to sort out.

The car isn't used daily - but usually only sits for a week or so.

I (probably) also agree with Simon. However - my thinking is this : I've already ruled out the pads (they had to be changed anyway) and discs are a consumable. I'll fit new ones - if it makes no difference then I'll stick the old ones back on, continue investigation and I haven't lost anything. It just means I have a set of front discs already the next time they need changing.

My car had also developed vibrations when I braked lightly, but under hard braking there where no problems.
I just had my front wheels changed and all vibration is gone.

The wheels changed? That's an expensive solution. Or do you mean the tires?

Tires of course

You've probably got a better command of it than most Americans!

By chance, I was less busy than expected at work today so I thought : rather than wait for the weekend, I'd take the afternoon off and replace the front discs.

It was ridiculously easy. From start to finish - including getting my tools out and putting them away afterwards, it took less than 90 minutes to replace both front discs. My car will never ever go to a mechanic to have the brakes replaced again.

The test drive was a success - no vibration. I guess it might take a little longer to prove that really was the cause but so far it looks good.

The only (unrelated) bad point - I've been considering replacing my head unit for an ipod compatible one. I decided that since I'd just saved myself the cost of one in labour, I'd use the test drive to go and get one fitted. However - it seems that the Alpine ipod compatible head unit is crap - you can either have a multi-changer or the ipod connection. I can already do that with the head unit I have - but I didn't want to lose the multi-changer (even though I know it's unnecessary with the ipod). Still - looks like I'll be keeping the head unit I have and ordering a £20 lead off the internet - and losing the multi-changer.

Now I just need to find something else to spend the money I've saved on!

If that doesn't incur the wrath of the Porsche Gods, I'll eat my hat - prepare for something to drop off!

DaveK

That's a good point - maybe I should delete that post!

Actually - the truth is, I'm going to make it even worse..... It's bonus month, and I am seriously considering blowing it all on the 964.

Ooooohhhh....so what are we talking? 993 Turbo?

DaveK

Blimey - your bonuses are obviously bigger than mine!

No - it would fund having the front seats recovered and the aircon fixed. But they are things I think should wait until nearer the spring. So I have a bit of a crisis - I'd like to spend the bonus on my car, but I don't know what on!

I can't even believe you've just posted this here!

DaveK

You're just jealous - my car is so perfect, I can't think of anything that needs improving.

dfinnegan

If that's then case then I trully am envious!!
