The brake pad anti rattle clips on the right front caliper was the cause of my knocking noise my problem. When I investigated, I found that they were missing, which means that the mechanic did not fit them when they replaced the pads.Nick Marriott wrote:Check your disc pad anti rattle clips. If these are weak or broken it sounds like a loose suspension part, especially with the windows open. If the noise goes away under braking, then this is your problem.
The clips are R 90 from the dealers.
