Not necessarily faulty , but almost certainly dirty . You ' d be amazed at how much crud builds up inside your pedals , especially if you have pets or live in an especially dusty area . I hadn ' t cleaned my pedals since I bought my G 27 a couple of years ago and didn ' t really think it was necessary . Then they started acting goofy brake dragging , gas being all spiky . So I took the pedal base apart and there was a TON of dog and cat hair in there . It was disgusting . I took it all out , and blew hard into all the pots . When I put it back together it was like it was brand new . It was SO much better . So I would take them apart and give them a good cleaning . I didn ' t take the actual pots out just took the base apart , then the pedal arms themselves , and cleaned everything really well . There are good tutorials online for how to do this .
