What caused my DS1.11 to become apple crumble?

[luigi33]

I bought the car already fitted with DS1.11 and did 1 wet track day and following a brake inspection noticed the pad was cracked and crumbling despite being a relatively expensive high temperature resistant pad.
Can anyone explain what causes this please?

Bloody hell that's terrible, what discs are you running?

 

[Daniel]

What wheel cleaner do you use?

 

[car.crash]

Is the car left outside without use for a while?
Pads rust to disc and then when you drive away it tears the pads up.

Race compounds don't tend to like cold and wet conditions. Have they been on the car a while?

Have you a picture of the discs are they a redish colour look like they have over heated which on a wet cold day would suggest a issue somewhere else

They look old to me ?

They look old to me ?

Yeah they do. If they've been sat over winter, that'll f**k them up. Damp and water gets in, freezes and breaks the material up.

Its a combination of all of the above to me,the pads have definitely been put through some serious heat to get those Scoring marks and start to break apart"Good lad":up:.SJ.
