Wanted to ask for the experienced opinion of the group.
Just started to ride my hornet 900 ( 12 years old ) and the brakes although great in stopping power are stiffer to operate than the cb1100 ( 8 years old ).
Over some days i have had every single part of the front brakes, master and both 4 pot calipers ( similar to cb1100 ) apart, cleaned, greased and re-assembled, none show any signs of wear or damage, fresh brake fluid in the lines, bled all the air out and also replaced all the pads; it's better but still sticky
.
#1 ;In the morning the lever takes more effort to operate and is slow to return. ( there is some extra play in the handle which slowly disappears as the piston slowly returns in half a minute or so.
#2; after a good couple of squeeze's it frees up to the point that it works acceptable enough and stays fine for some hours, but in the next morning........
#3; pretty sure i have narrowed it down to the master brake cylinder and the only culprits are the rubber seals on the piston.
#4; this has possibly been like this for some time but i started noticing it after comparing it with the cb1100 and another hornet 900 at a dealer closeby that works fine and operates light like the cb1100.
#5; the brakes drag slightly when stiff but release fine and run 100% clear when the lever feels free.
Anybody had a similar scenario and what was the cause?
