197 Front Brake Discs??

[Amos]

Hi there....

I own a Clio 197 Cup which I use for Track Days.....

I fitted new Brembo Brake Disc's which where bought from Renault, and a set of DS 2500 pads....

Now after one track day I am getting a vibration under braking..... Which makes me think they are FECKED already....

Any Ideas, etc...

Or am I better getting Brembo HC discs, and where from...

Cheers..

Warpped disc or could be uneven wear on the pads but id say its the discs

How do I tell which it is, I don't want to fork out for new discs unless I need to....

Take them off and sit them on a flat surface, you will tell soon enough.

 

[BioHzrd]

Take wheels off and spin them by hand should be able to tell that way mate

it will be pad deposits on the disk you could try rubbing the disks with emery paper to shift the deposits the quite often happen when you stop the car in the pits if you keep your foot on the brake pedal for to long

What grade of paper should I use........

medium / fine you don't want deep groves in the disk just take your time
