Apes Member 35 Member For: 16y 10m 14d Gender: Male Posted 04/12/10 11:11 AM Share Posted 04/12/10 11:11 AM Hi guys,I have DBA 5000 rotors and 4 pot brembos fitted to the front of my BA ute, I have done approx 7-8 track days on them and have noticed lots of small cracks (direction from the hat to the outer edge of the rotor). They work great still, however I do have my concerns. Any ideas?? Link to comment https://www.fordxr6turbo.com/forum/topic/71990-dba-5000-rotors/ Share on other sites More sharing options...

How big are the cracksCould grab some pics tomorrow. They are only small hairline cracks however the DBA 4000 at the rear have none, prob due to not doing much work.

Benny Member 1,869 Member For: 21y 8m 16d Gender: Male Location: Newcastle Posted 04/12/10 09:55 PM Share Posted 04/12/10 09:55 PM My experience with my 4000 series is they have these same cracks from doing track days and have had for close to 18 months with no signs of ill effects. My brakes still perform just as good as they always have and haven't got any worse than my first track day.If you want to be sure then give Matt at Races Brakes a call.Benny Link to comment https://www.fordxr6turbo.com/forum/topic/71990-dba-5000-rotors/#findComment-1060840 Share on other sites More sharing options...

Good point about the change in color I will check. My 5000's operate as good now as they did 2 years ago with these small cracks. I will give Matt a call to confirm that these samll cracks do not become an issue.
