My 2012 Model Scott Sub 10 has recently been experiencing issues with the rear disc sticking on my daily commute and getting so bad that I have to stop, wait for it to cool and then push the disc a bit to give it some space. I believe this has been caused by the terrible weather that the UK has experiencing, perhaps with some debris becoming lodged in one of the pistons.
I decided to take the pads out this evening following the guide that came with the bike and cleaned any dirt around the pads but there is still some friction there.
I am debating pouring warm/hot water over the whole brake system in an attempt to remove anything that may still be lodged.
What advice would you you suggest aside taking it to my local bike shop?
