Cracked Rear Disc

[Goders172]

As above really, got to work this morning and the car was making awful vibrations under braking, the right hand rear disc has cracked in two places from the outer edge right down to the hub, and is now working its way round the hub (when the 2 cracks meet that section is gonna fall out). Wouldnt mind but i have to get it home (30 miles from work) and the new ones are £140:dapprove: on order from GSF

Gonna be an intersting drive home if the crack gets any worse

try not to use you're brakes. use the gears.

Hmm...

...if the cracks do meet while you're driving, you'll be looking at replacing lot more than just the disc! I'd go for the safe option, and not drive it. :S

PS I don't know if it's possible, but could you take the pads ouf of that particular caliper? Would it affect the pressure of the rest of the system?

that happend to a friend on his 182 cup after alot off heavy braking, but he was running brembo discs and pads and both rear disc cracked in two, try changing your pads and use good brake fluid my friend has done that and it hasant happend again. also try using your gears to slow down like the man above said

Also happened to me on standard Renault discs. 4 cracks each at 90 degrees to each other - looked like a manufacturing flaw to me.
