Slight squeak with extra weight
So i noticed a slight squeak coming from the front of the bike when i had a passenger on the other day. I was trying to pin-point its location but it was proving difficult. The noise isn't there when it's just me riding.
Any theories? I can't put my finger on it yet.
I had a look at the disc brakes and put marks around the disks with a marker pen, the span the wheel and saw some of the pen had been taken away. only a fractional amount though. Whats the correct separation for disk pads?
