Usually the need for a brake service. Check to see if the caliper slides and brake pads are moving properly and lubricated correctly. If the wrong lubricants are used, it can cause issues with the operation of the caliper.

Hello!
I have a similar problem with my Hyundai Tucson 2008, the rear left brake rotor is wearing only half an inch from its center. Another cause can be a clogged brake hose?
When I changed the brake fluid with a pressure/ vacuum pump, at the rear brake hoses the fluid was squirting very weak. at the same time on the front hoses the squirt was much powerful. this is normal behavior?

I have checked the left rear brake pads (in and out), I cleaned the caliper and the caliper mounting bracket, the pad retainers and the brake pads still rub only on the inner side of disc rotor. The brake rotor is rusted 1 inch from the outer edge on the inside and the outside.

What could be the problem?
