Just my brakes i bought about 10.000miles ago off here are showing alot of cracks all the way round in the middle. As this been known. They were bought from a known company on here. Just that im doing a track day next monday do you think they will last

Send them back mate that doesn't sound right to me. Cracks FFSAKE?! If they break up under braking you will right in the ****e.

As what Dave said it's dangerous.

I will make sure i get the write company first before contacting them

Always a good start. :thumb:

Hi, that type of cracking will be deemed OK - you've been giving the brakes a good workout thats for sure. Its when they get to the outside edge you need to worry

Depends what abuse you have put them through. If it just road use then that's pretty poor. If you've been hammering it on track then I'd suggest that it's a bit more acceptable.
