Brake Discs - mark on them.. MOT fail?

daleuk_3

From when I have a problem with my ABS.. the ring had bent and this marked the inside side of one of the discs.

This hasnt effected performance of the brakes.. but would this mark on the disc cause a MOT failure?

If so I will replace it. (I presume brake discs dont have to be warn to the same level?)

Thanks for your advise guys.

I would not expect it to fail the MOT unless badly scored.

You should replace both disks at the same time if you do end up replacing it.

Personally I would try and gert it through as is. The MOT station will soon tell you if it is affecting breaking performance.

Yeah, it will depend on how deep the scoring is - minor scoring will probably just be an advisory.

Even relatively new discs get covered in little ridges from uneven wear.If yours are scored then the pads will wear it off eventually.
Is the abs still working as the rings are there to detect whether that wheel is skidding?
