A few weekends ago, I took my S3 for a day of lapping with an instructor at my local track: http://www.calabogiemotorsports.com/ . It was incredible fun and the car performed very well. Both my instructor and I were really impressed with how it handled the 3.5 hours of hard track driving, while passing cars we had no business passing.
However, it is clear that the repeated braking from 200 km/h to 80km/h took a toll on my brakes. We didn't notice anything on the track, but on the drive home it was clear that they suffered some heavy wear. Not all that unsurprising, but I am hoping to get a little input on what needs to be replaced to get them back to near-new condition.
There are two main symptoms:
1- increased brake pedal travel- engagement is now much later in the pedal travel, but feels totally normal otherwise. After 1000kms of driving I don't really notice this anymore- not sure if that is because I have become used to it and need to bleed the brakes, or if the cause was pad wear that the callipers have adjusted to. Any thoughts?
2- The brakes sound quite a bit louder upon application (a low-frequency noise, almost 'humming'), and there is also pulsation. You can't really feel it through the pedal, but you can hear the pulsating noise. It sure sounds like glazed pads, but would those cause the pulsation as well?
If anyone has an idea what needs to be fixed/ bled/ replaced, it would be appreciated!
Thanks,
Mike
