I guess there are different degrees to the condition but mine are not too bad, i notice them every now and then but they dont really bother me so ive not got round to soring them out yet, got the mot in a few weeks and though i best check before it gets failed
The MOT doesn’t check the discs for warping, only the effectiveness of your brakes.
As long as the brakes pass, you will receive an advisory for a pulsing brake lever.
Having warped discs alone will not be a fail if the braking efficiency etc is ok.
I had this once (the bike passed the MOT by the way) and asked if it was a warped disc. He said its not for them to say unless I pay to have it checked.
I went home and eventually found out the wheel was buckled from a previous owner :crazy:
