I've gotten back on the bike again since a log hiatus and I noticed that my rear brake lever is a bit sticky, in that after braking, it doesn't rebound back to it's standard position. One time it stuck so bad that the brakes were even engaged. I can compensate for this on my rides by just giving it a little flick into the open position and continue on my ride. But I was curious what the best way to fix this was. Just get some WD-40 and spray it on there? When I'm not riding, just with the bike here in the living room, I also noticed that when I squeeze the brake, there is a squeek sound by the back wheel where the break is hitting the rim. I don't hear that sound on my front brake. Could there be something more serious than just a sticky lever?
EDIT: PS, pics available on request, just not sure if or what pics would be helpful.
Check them for . . . ? I'm not sure what I would be looking for, other than that they exist in a continuous line from handle to QR unit.
EDIT: Thanks for the tip on the WD40. Is there a better lube to be used on bike components?
If you insist on a spray lube Boeshield is by far the best. You don't want to use a spray lube on greased parts like hubs and headsets. Check the cables to see fi they are sticking inside the housings.
