| Description of the problem | In regards to my vehicles rear disc brakes. From my experience and education it is very unusual for your rear brake pads to wear out before the front do. Do to weight and inertial pushing harder on the front brakes ( this vehicle is much more heavier in the front than the back). My rear pads wore out before and from some research in forums on my model car others have had same experience. I believe there is a defect here and it might involve the proportioning valve sending too much pressure to the rear calipers in comparison to the front calipers. Might of be an adjustment in the valve that is causing issue. I would like an investigation into issue . I can provide assistance if needed in regards to vehicle as subject for testing. 2009 hyundai sonata gls 4-cyl automatic trans ,disc pads front and back. |
