I have started to have issues with my G29 pedals after purchasing my set up 2 years or so ago. The throttle pedal was jumping when held at full throttle so i took it apart and gave it a clean with some isopropyl alcohol and also did the same to the brake at the same time as I had it in bits. The throttle is fine but now I have noticed the brake sometimes shows a slight input after it has been released. Maybe I didn't clean it well enough? I did buy a potentiometer to replace the the throttle, but without some modification to the new pot its not going to fit. The shaft size is bigger(diameter and length), the pot thread and lock nut is bigger (a bigger hole would need to be made) and the orientation of the shaft is opposite (the flat part is on the other side) My questions are 1) are there any direct replacements or good tried and tested fixes for these? 2) I'm thinking of biting the bullet and replace the brake with the TRUEBRAKE mod. Does anyone anyone have any experience with these? 3) what other modifications are there that people would recommend?
