Each time you put your foot on the accelerator, brake or clutch pedal, you wear off a little of the pedal's rubber cover. With time and miles, you can wear right through the cover. To remove the old cover from a brake or clutch pedal, pry its lip off the underside of the pedal. Slip on the new cover, and work the lip around, Accelerator pedals are either held to the throttle linkage by clips on the underside of the pedal, or are hinged to the floorboard and held there by mounting screws.
