Hi All,
I posted on here back in August regarding a clicking noise I was getting from my wheels on my 2015 E220:

I took it back to Halfords, who originally did the work, and after confirming there was a noise, they sorted it by installing new pads and discs on all the wheels and the noise went away.
Now fast foward to today and there's a new noise developed. It's a metal on metal clank once per revolution of the wheels, it could be mistaken for driving over a loose manhole cover, even though I wasn't driving on one. It can be heard only when my windows are open and only happens when I'm driving really slow, such as being in Drive but not touching the accelerator and it goes away when I speed up. No difference going over bumps or turning. Checked under the car, assuming something was caught, and nothing. I called the AA out because it sounded like something was loose.
The AA chap turned up, jumped into my car with me to drive around the block and he could hear it coming from the front drivers side wheel. He takes a look and can't see anything. Jacks it up, spins the wheel and nothing. He then removes the wheel, and notices that when he's turning it with his hands on the disc, it's getting really stiff at one point, the same point every revolution. When it's getting stiff, he notices the brake pad on the inside of the disc is moving out, and then moves back in when it's looser. There's also a click noise when the pad moves out, not anywhere near as loud as what I was hearing though. He's saying there's an issue with uneven wear on the disc and that I need to take it back to Halfords for them to sort it again, and that click is what I will be hearing, it will get amplified when driving (can anyone confirm that?) No other sounds are being made from it, so it must be that click, and it's not right as it should be the same friction all the way around the disc, fair enough.
So I managed to book a free brake check with the garage tomorrow, so I'll see what they say. In the mean time, I'm wondering whether anyone else had a similar issue and what it turned out to be? Defective brake disc? Issue with the caliper?

Clicking noise from wheel? | Wheels, Tyres, Brakes & Suspension
Hi All, I've been having an issue for a while now on my 2015 E220d esate where there's a clicking noise that seems to be coming from the front driver side wheel when either braking or steering to the left. It started a while ago after having new pads and discs installed on the front wheels, and...
