    Under normal riding conditions around town has anyone noticed if their rear calliper or disc gets hot ?
    I have cleaned the calliper pistons and springs etc by the way

    Is it the parking brake causing the drag?

    Checked that as well there is mild drag here, doesn't stop the wheel from turning if I push the wheel by hand though.

    Should not be any drag from the brake pads touching the disc, but remember by rotating the rear wheel you're turning the drive shaft and a gearbox shaft so there will be resistance from them, if the disc IS getting hot that can only be caused by the pads contacting the disc with SOME pressure, either it's the h/brake not freeing properly or the caliper sticking a bit, you need to get it seen too.  :034:

    I just rode the bike at speed for 30KM and only used the front brakes. When I stopped I checked the rear disc and caliper and they were cold, therefore the tiny drag I noticed has no affect in generating heat. So the heat is obviously only generated when using the brakes. Can someone check their rear disc after they have ridden their bike and see how hot it is please.

    There's nothing wrong then, it would be hot within a few miles if there was incorrect pad contact, discs do get hot of course with brake use, (depends how often you're using the brakes of course,) nothing wrong with yours it looks like.

    It might be worth remembering the Crosstourer uses the Honda Combined Braking System so it applies brake pistons at both wheels regardless of which brake lever you are operating, which might lead to a bit of unexpected heating of the rear brakes/discs if the front brakes have been used to any great extent. Just a thought.

    Not so.
