Front brake pad

[ValkyrieRider]

Yesterday while riding notice my front brake grinding. Got home and removed front brakes. The left side pads were fine but the right was bad. This is looking towards bike from front. The pad on the piston side was down to the backing plate while the outer pad was fine. I belive they should wear them same. Any thoughts on what could be causing this?
Thanks Eddie.

i would check the operation of the one that looks good. you may be putting all the pressure to 1 side, oooooorrrrrrrrr, the one that looks bad is stuck in. my 2 cents

Your caliper is sticking in the pressure position. In other words, when you apply the brakes the front calipers squeeze the bads to the disc rotor. When you release the brakes, the calipers should ease back a little to a slight brake drag. One of you calipers is not easing back to a rest position, it is staying in a pressure position and contantly applying pressure to the pads, thus causing that pad to wear excessively. Remove both calipers and rebuild or check the caliper sliders for binding or corrosion.
      Next time, try to describe direction from a sitting on the bike position, then everyone will know what side or direction you are trying to communicate.

It could be the calipers (as already stated) but it could be the axle not in all the way and the rotors not centered.  Usually this results in the LEFT (clutch side) rotor rubbing on the caliper, but if yours is just a tiny bit off, maybe theyre just a bit tight on that side.

PS...left and right is always stated as the bikes left or right as you are seated on the bike

Thanks for the replys. I am also thinking it is the caliper. I put new pads on and it seemed hard to get to push back in to the bottom position. I will be rebuilding both today or tomorrow. The front wheel looks centered. Also I would think the pads on both calibers would be worn uneven if the wheel was off.
 Thanks Eddie.

You should see your fuel mileage increase as well since you won't be fighting the brake.

Compared to what?

If you look at how the wheel and axle tighten you would understand that the right side caliper will always be positioned properly.

Well now I am starting to have my doughts on if the wheel is centred. So tomorrow I will start by checking that followed by rebuilding the calipers. Got the seals for the calipers today.
Thanks for your help.
