Hi All,
Last Nov I had the rear pads and disks changed on my 16V MK3 for the MOT as they had a wear lip on them.
During this summer I discovered that I had a partially seized rear caliper and by the time I found it the disk had turned blue

I replaced the caliper and pads,on both sides and checked the disk for distortion. It was fine,with no perciveable runout so I decided to leave it for the time being. The brakes have since performed as they always didand the car pulls up straight under all conditions.
Question - Is a brake disk in this condition an automatic MOT fail ?
