996 TT, brake judder

[DJones]

Hi,

I seem to have developed brake judder, cruising its fine touch or hit the brakes and I get a judder through the wheel. Recently had an MOT and checked all the bushes myself all seemed well, any ideas prior to me taking it apart?

Seems worse the hotter the brakes get.

Thanks

Darren.

Done any recent track days?

Vibration on braking is discs with uneven pad deposits, or something gone in the front suspension (is there a 'track-rod end' on a 996?)

Nope never done a track day in it. I thoroughly checked all the suspension parts all seemed fine.

Your discs will be getting too thin and warping, which will be worse when they heat up.

Mine are doing the same. Just ordered myself some new discs from porscheapart - £175 for the pair. Not half bad if you ask me! :thumb:

Mine do the same... Pretty sure it's time for new discs!

I presume you've tried doing several high speed heavy braking applications to remove any deposits? Are the discs visibly worn, ie lips around the edge or cracking between the holes?

+1 on the thin/warped discs: I had exactly the same steering wheel judder when braking - new discs all round was the solution.

I had broadly similar symptoms to yourself ie juddering that got a lot worse the more I was braking. Sebro discs and ATE pads on it which were only 8000 miles / 2 years old.

I have replaced the fronts with Pagid discs and EBC yellow stuff pads; approximately 30% of the inner surface of the original discs was gone. what a big difference that made.

However....there was still a slight feeling of vibration and have checked the inner surface of the rear discs and they are the same. New discs arrived last night and hoping for the pads to arrive tomorrow so that I can get them done after work.

Good idea to check if that is the situation with yours.

I don't think I have been driving the car enough hence the damage nut I was never impressed with the brakes that were on the car.

I had a similar judder on the C4s i collected last week. It was just surface rust on the disk. 60mph to 10mph 10 times or so on two succesive occasions - late at night, then the following morning, cleaned the pads and the disks sufficiently and the judder is no longer there.
