front brakes

Should the front tire be freely spinning without the brake pads touching the rotors? My back tire spins freely but the front has a tiny bit of friction on it from the brakes, got one person telling me its normal and one saying its not.

The bike passed MD inspection this way a few weeks back.

It makes a sssssssh sound of the pads lightly touching the rotor if you spin the wheel.

Pads should always be in contact with the rotor so what you are experiencing is 100 % normal.

Ok good, I never noticed it before and while riding yesterday I noticed the sound of the pads touching the rotors while out riding, no idea why I never noticed it before.

The brakes work as they should, just got conflicting answers from people that own different bikes and it was making me nervous.

X2^^^ 100% normal. The pads on you car are probably doing the same thing, but you never hear them inside the cage.

Cause pushing the cage around while it's not running would kill most of us...

Ya gotta remember... the rear drum brake has a spring that moves the brakes back to the unengaged position, the front disc brakes have no return spring.

Doesn't matter what kind of bike it is, disc brakes work the same way. So whoever told ya otherwise..... don't put too much confidence in what they tell ya.

Actually the rubber boots on the caliper pistons pull slightly the pistons (and pads) from the rotor. Now the difference is whether you only hear a bit of rubbing form the pad to the disc (sintered pads are lot more noticeable than organic/kevlar pads) and that the brake binds the disc, in this case you want to try one caliper on / one off to see which is the one that's binding.
One tip that might help if the rubbing is annoying you is to get the calipers off the carriers and push all the way in the piston. This will get the piston lubed with the brake fluid and may retract a bit more under the dust boot.
Just my two cents

Don't know about that and if so, it is very slightly.
But still, the front brakes don't get fully disengaged when letting off the brakes like the rear does.

I go along with Mushu that the front pads do retract very slightly, they could be a little gummed up. . I tried mine and did not hear anything, did you have any work done on the front wheel. Like a tire change or removed the front wheel to do maintence. If the noise is intermittant as it spins, the rotor could be warped. If constant I would go with what Mushu said, or maybe taking them apart and cleaning them. I had a older car that did the same and I had to take out the piston and clean it up to make it work right.
