Hi jut bought this car 2days ago as my old car died, anyway. The car had been sat for just under 10 weeks unused with a cover over it but outside. All the discs had surface rust which after a few miles was quickly removed but the rear right continually makes a noise every rotation like a clicking noise the rust hasn't fully come of this disc and it appears to be wearing off unevenly. Is this likely to be a new caliper, pads and discs? :( Now under heavy braking there's a small shake through the steering wheel.

Question 2 When the car is sat and started all normal dash lights come on and go out like they should until you pull away and the Abs light comes on and won't go out until you swiitch off and back on again. Guy I got the car off said he bought the car like it 6years ago, but it passes Mot's as it goes out when its 1st started, will it still pass or does it need sorting to pass the next Mot?

Thanks in advance
