How freely should the front wheel spin when on a stand? - chync_imp - 03-25-2018
I just replaced my clutch and brake levers and when I put the bike on a stand to check that the front wheel wasn't binding in the brake calipers I was surprised at how little free spin there was.
With a hard spin I think it may go an entire revolution if that. You can definitely hear the brake pads lightly rubbing on the rotors.
I assume that's normal?
I don't recall ever trying this before so I'm not sure when to start looking at cleaning the caliper pistons and checking the master cylinder. I have 26k miles on it now.
Found a video that has about the same about of drag as what I experienced.

I guess that's normal?

As the video you researched suggests, disc brakes always do rub. However, if you are overly concerned go for a ride for a couple of miles on a quiet road, avoiding any braking (if possible!) and then stop and feel if there is any heat in the front discs.
If they are cool you do not have a problem.

in my experience, cleaning the retaining pins will help a lot. sand paper works well.

I agree. Very often when I replace brake pads on my bikes the pins that run through the pads have hard residue caked on and need cleaning to allow the pads to run free.
If the pins have never been out in 26k I would look there first. Don't be too abusive as crap likes to stick to a rough service. Make the pins smooth and shiny/clean.

+1... and the pads, pistons and calipers free as well, as a general rule ... and then spinning brake rotor will take care of clearance/adjustment if master cylinder/lever are not binding & compensating port properly reavilling
Soon will
mine = temperatures rising
