Front brake noise question
ok, did a brake fluid, rotor and pad change of this weekend. Heritage classic 2009
Basically, took the caliper off, removed the pads, drained all of the old brake fluid, took the wheel off, exchanged the rotor, put everything back on.
I put new Lendell pads in. When I reinstalled the caliper the front wheel turned nicely without the pads touching.
Then i proceeded to bleed the brakes. Put new fluid in, with the help of a friend he pumped and blead until all the air was out and we only got clear looking fluid.
Since then the pads are dragging along the rotor. The wheel will not free spin when the bike is jacked up. The brakes stop the bike fine, the only thing is after a few brakes and they are and the rotor are warm I can heat it everytime I hit the brake. It sounds like a cicada (speeling?). I have also noticed that the rotor is really hot even after a short ride up and down the street. alot warmer than the rear brake. (my guess that is from the rubbing/draging)
my question is this normal at the beginning after changing rotor and pads? is this part of the wear-in? Or is something wrong?
I notice no shaking or wobble at all from the front wheel, so no issues there. Also not squeeking from the brakes.
thanks for your help

You said the wheel will not turn freely when on a jack...try that again...if it will not turn freely, open the bleeder screw...it it turns freely after opening the screw,the master cylinder has problems...if not it is the caliper.

Did you "top off" the master cylinder after bleeding? I've seen people put enough fluid in to leave the piston no where to go. This can lead quickly to warped rotors. Remove the cap from the MC. If it's right up to the top take some out or cover things well with a towel. Remove the caliper(s). Spread the pads using whatever you used the first time (I have a couple of pieces of Home Depot paint stirrer that I spread with a big screwdriver.) Remount the calipers. Check the fluid level before you pump the lever. Put everything together and pump the lever several times. That should take care of it.

You need to clean the pistons and pad pins with brake cleaner and lube pins.

However if the brakes were dragging before you bled the brakes then the problem is mechanical at the Caliper.
