Clio rs 200 ff n cup
Hi did a track day at cadwell yesterday we have got a ff 200 with cup chassis and also befor the trackday I replaced front disks and pads for oem brembos and rear pads for brembos as well also I bled the whole system through with new fluid and also had 4 nankang ns2r's fitted so we thought a good day was in store.The brakes were better than they had ever been due to the rears being seized to the calliper carrier.
Anyways we got to cadwell and its was very cold frost still on track so did the sighting laps and all was fine, after our lass went out for 5-6 laps then came in didn't push to hard as frost on track and cold tyres etc. But then I went out all was fine until about six laps in the pedal went soft like brake fade so I came off and we let the car cool down before going out again, this continued until dinner break with the brakes feeling fine when going out but after 5-6 laps the pedal kept going soft.
After dinner I think we got about 10 laps between us, letting car cool down inbetween going out before the problems started again, now it wasn't only the pedal feeling s**te the whole car was vibrating under heavy braking not all the time but often, it wasn't a vibration coming through the brake pedal it was coming through the whole car and it was horrible. each time we would come in let everything cool down then go out for another 5 laps until it happened again this continued until we ended up finishing early. The car was still braking when this happened but pedal feel was s**t and the vibrations were horrible.
The brakes were horrible on the way home the pedal was soft as hell and there was little braking force, all in all this ruined the day. so before I go poking around does any one have any ideas what could be the problem any help will be greatly appreciated.
