I think they may be sticking. When the car's just rolling you can feel it slowing down much quicker than usual, in pulses, and when i take the handbrake off to go it's as if it's still got the brakes on cos it won't roll
And when braking the steering shakes and you can feel knocking/rattling from wheel/brake area

Any ideas??

 

disc's are fooked,and you may have a sticky piston
take them off and have a look dude

I was half expecting my wheel to come flying off
