Cracked brake discs

[stainesy]

i was chatting to a mate about my car earlyer and he pointed out that my rear brake discs need replacing.
i new i needed new ones but i had no idea they were this bad.
there is a 8mm lip all the way round and both back discs have a hair line crack going from the centre out to the edge.
how dangereus is it to be driving my car with the rear discs like this?

8mm lip?? didnt think the discs were even that thick, if they really are that bad surely the MOT would have failed them?

well you better get em replaced then, if the lip is that bad they will have passed the maximum run out id guess

well ive not long replaced the rear disc's on my 8v and the thickness is 10mm so im surprised that there's anything left of the discs

Stainesy did say the 8mm was a guess .

even 3mm of a lip its a hell of lot of wear on a disc though.and if thats on the front of the disc imagine what the back is like. stainsey you need to get a pic up and let us see how bad it is
in saying that if there is a crack on the disc get them changed asap, it ain't worth the risk
