So after my bike lying for 3-4 weeks, it appears it has not done the rear caliper any favours. The function has been greatly reduced, and the brake is sticking. I assume (?) That this means the caliper will need stripped and cleaned and rebuilt, which is fine, can anyone tell me how many seals I need to do this? I see wemoto selling them as singles, and they don't do a kit for the rear calipers.
I'm not interested in changing for a thou caliper, as I really want to keep it OEM (I plan on selling soon, so don't want the hassle of explaining that the rear caliper is different to someone who may not be a member from here).
Aside from giving the piston a good clean and changing the seals, is there anything else I should be looking at that may be affecting the performance? The fluid is only 4 month old, so I'm confident that's ok, although it may need bled again too?
