Decided to replace front brake pads myself today, a small DIY project! However couldnt open the calipers as wasn't sure what key is needed.
Does anyone know what Hex Key (Allen Key) is required to open Front Brake Calipers on E70? (Definitely not the standard 7mm, tried this one and is too small, looks more like 8 or even 9mm).
Please advise!
Thanks!
