Brake Pads - were these installed incorrectly?

[Xplore Wallke]

1100 miles on X3Pro and when removed pads, looks like they were not properly aligned at the factory or is this normal? See pad where top 1/4 was not used at all which is illustrated in the Rotor. You can see where the dirt is untouched on part of the rotor.
How do I adjust the caliper so that the replacements utilize the whole rotor?

if they were seated properly and not in or out of the caliper then it would be the caliper that's off .

Thanks @fooferdoggie, they were seated properly. Do you know how to adjust the calipers?

Part 4 for your specific case.

And before you re-align your caliper, ensure the axle was fully seated into the dropouts!

 

[Xplore Wallke]

Yep, saw that on the video, def gonna check to see that its seated properly which may have caused this issue

 

[fooferdoggie]

yes you cant really adjust the height the adapter is what sets the height. so it may be the wheel not in properly. but my first mid drive had one wrong bracket so I had the same issue with the front pads. it was fixed on warranty. so if the wheel is seated right then it is the mounting bracket that's wrong. you will have to replace the pads and maybe the rotor

Something is wrong with the caliper mounting bracket, which also functions as a spacer. If the wheel is installed properly, the caliper mounting bracket is wrong. There are many different size brackets to space the caliper off the frame so it pads contact the disc properly. This is not an adjustment issue.

Thanks everyone! @Max Black can you please respond as to whether it's the wrong mounting bracket or an adjustment needed

I am not sure about the wrong mounting positioning, I just recently did a brake change and my brakes, front and back, were looking very similar so I would say nothing is wrong.

Really, that's strange for sure

There's a mismatch of components then. The spacing is not optimally matched between rotor - caliper - mounting bracket.
I have a somewhat similar issue with my front brakes in that the rotor surface isn't fully utilized and look similar to the photo in the OP... but the pads do wear fully and evenly. The breaks work well and the pad wear is more important so I just live with it. I would address fixing it if the pads were grooved and not wearing correctly as in the OP photo.

The front weren’t nearly as bad as the rear but still a bit like OPs.

I'd look into changing the mounting bracket and/or the removal of spacing washers.
Realize that washers can be conical and aid in the alignment of the caliper.

i discarded the 160mm rotors and upgraded to 203 and 180, using RT-66 rotors and shimano mounts. Had to add a 2mm spacer for the front for some clearance with the caliper.

I’m using the whole brake pad surface based on the rotor wear

Replaced my brake pads and you can see that the
brake pad wear is even on the 203 compared to the 160.

Can I just say that this thing would be a rusting hulk in the corner if it weren't for learning all of this from you all. Thank you! This forum has helped me I think 10 times now.
