What can fail
Small stones or debris can lodge in a gap between the brake pedal and guard, causing the rear brake to drag. This overheats the rear brake, potentially damaging it or causing lock-up or failure. Front brakes may also be affected on some models.
What the fix does
Dealers will replace the rear master cylinder rod end and remove the brake guard if installed, at no cost.
