how worn would discs need to be to fail an MOT?...
I've currently got a little Polo GTi which will be due it's MOT in a month or so.
It recently had a new clutch, and the garage tried to get me to get the front discs and pad's changed as they said they were due, but they don't look too bad to be me.
There is some wear on the discs, and they're 'lipped' slightly - ie prob 1mm of wear, so little lips on the edges.
Anyone know got any idea what would be considered too worn to fail the MOT???
Thanks

i am an MOT tester , you cannot fail a disc on been to worn , it is simply impossible as all manufacturs specifie different thicknesses and there is no way of measuring thickness of a disc with the wheel on (on most cars ) so you just dont test it you can fail a disc on excessive corrosion ie if 2/3 of the disc is pitted os excessive scoreing which dont really happen or u can fail it on cracks, but thats it definatly not on thickness however the brake pads must have atleast 1.5mm of friction materel left on them hope this helps

Thanks guys
I've just had second look at them, and I reckon I'll chance it as the lip is not that bad really, probably nearer 0.5mm, and the pads look pretty new.
Does seem like a slightly grey are though really.

check the inside surface of the disc as that is where its most likely to corrode people often think there brakes are fine because they are shiny on the outside but the inside could be just brown with corrosion

For what a pair of discs and a set of pads costs, and the time it takes to swap them, is it not worth replacing them just for the peace of mind
Unless of course it's the mother-in-law's car

I bet it was nothing the judicious use of heat, cold, and a ******* Big Hammer couldn't have shifted
