One trackday later: brake issues (clio 197)

[Rabbit1986]

Hello,

I've done my first trackday. On the straights I braked from 180 km/h ( about 110 mph ) to 15 mph.

On the end of the day I felt a heavy shaking in my steering wheel.

On the way home I kept feeling it, when I did not brake hard, but normally.

Anyone has an idea what's the problem?

If the problem are the disks ( they somehow folded a bit ), what's good stuff to replace original brakes? And not too expensive please :rasp:

Thanks,

the Belgian newbee

material transfer to the discs, brembo do replacements for not too much money

that could be just brake pad deposits on your disks.

just use the high pressure water jet from a car wash on the disks and you should be able to remove most of it.

I had that when braking from around 70, Renault said i needed new pads, changed them and its not happened since.

Okay, thanks.

I'll keep you guys posted, when my mechanic is going to look at them next week.

I don't know, if it is related, but. The problem was getting clear after I picked someone up in the pitlane. Dunno If i just stepped on the brakes then ...

warped discs by the sounds of it mate, replace them for aftermarket ones, check out k-tec.

As above could be pad material transfer or warped disc's. Personally i would put my money on it being warped disc's.

Is the shaking through the brake pedal or steering wheel.

Shaking through brake pedal is almost always rear discs and through steering wheel almost always front discs.

Use emery paper on the discs doesn't take long to do both sides, if the shudder is less, then it can be pad material build up.
Next time chuck in set of EBC 41539 fronts and 4680 rears and keep these for track days.

It is shaking the steering wheel.

But only when I brake not too hard. Actually I have the impression that when I brake with the side of my foot, I don't have it.

It also starts to shake when I slowed down to 50 km/h and below.
