Doesn
no
Anti -rattle clips not installed or not installed properly
prob caliper issues and/or alignment
Pads loose in caliper? Anti-rattle clips not installed or installed incorrectly?
There are no bearings in brakes, but the hub has large ball bearings
You have an alignment problem. Possible problems that help with this are tires, brakes.
Not likely but it will wear the tires out.
the brakes were not fixed properly some part is installed wrong
no, if you've ever bled brakes, use the same method you used before. it should work fine.
because the alignment is off Warped or out of round brake rotors/drums.
yeah it will have scratches on them you are using your brakes my friends its not like your brakes are made of cloth or sponge ofcource its normal for rotors to have scratches on there but makes sure they are spread evenly on there that they were installed correctly
Tires are a wear item just as brakes are. They will wear from friction. Properly inflated they should wear evenly. PSI inflation should be checked regularly. If they are not wearing evenly the vehicle may need an alignment.
