Discs deglazed

[911 (997)]

My OPC recently told me I should have my discs deglazed when I told them my braking performance wasn't what I was expecting from my recently acquired MY03 996 C2. Especially when I recall the excellent braking performance of my old Boxster. But I was wondering what is involved and how did the discs become glazed in the first place? There was mention of some machine they use to rough up the surface of the discs. Thankfully as I only bought the car from an OPC 5 weeks ago I'm expecting the cost to be covered by warranty or goodwill. By the way, the car has only done 9,000 miles. :unsure:

Short of removing the discs or pads, the way we used to do it years ago was to take a coarse grit sandpaper and sand ACROSS the disc from inside to outside. The intent is to scratch the surface which will also deglaze the pads when the brakes are next applied.

However, I find it unlikely that this is causing any brake problems due to the fact that the design of the rotors should be preventing glazing in the first place. Are you saying that ABS does not kick in when the brakes are applied hard? If it does, then there is no problems with the pads or the discs. If not, could be air in the brake line.

I still have the original pads and discs on my car and after 45,000 miles of hard street driving, there is no fade.

Thanks for the reply. I don't know if ABS kicks in or not as I don't think I have ever had to break hard enough for ABS. :drive: However it seems I need a lot of pressure to stop the car, noticeably more than my Boxster. My OPC said there is some form of machine they use which roughs up the surface of the discs.

The thing is that when I look at the discs they don't look glazed. They look fine to me.

Another thing is that once when I had to apply the brakes hard I noticed a juddering through the brake pedal. :eek: Is that normal? :unsure:

The "juddering" is most likely the the ABS funstioning correctly. To ease your mnd, try driving another 996 at the dealer and see if the braking system seems different than your car.

Well the car is booked to go in to the OPC for the brakes and the horn (it is only on low tone at the moment, not hi and low), so I will wait till then and see if they are improved.

Now for something different:

The only time I've had to break hard is going through the Limehouse Link when I completely forgot about the speed camera just after the entrance at the Canary Wharf side heading to the City. I only remembered when I saw the white lines on the road. Given I go through it every day I was pretty pissed at myself :cursing:. The thing is I got flashed but haven't been ticketed yet, and it was over two weeks ago. Has anyone else been flashed in the Link without getting ticketed? The reason I ask is that I thought the cameras were digital so there was no chance of them being out of film?

Let us know what happens after the fix on the rotor. I'd not want the rotors to be cut as that makes them thinner. Hopefully, they are just sanding them to rough them up.

RE the flashing camera, you'll problaby get somehting in the mail in a month or two. If other cars are around you, maybe the flash is for them. Otherwise, you're toast. It takes a while to get a ticket as someone has to read the plate and pull out your records. It's impossible to fight such tickets...
