Depending on the layout of your pedals, all the pedal rubbers do is make harder to go from the accelerator to the brake.
Clean pedals thoroughly, and stick on the self adhesive emery you get for skateboards. Cheap, easy and better
I lost the brake pedal rubber on the P4SS after half a year and never replaced it because it is mich easier and faster to go from the throttle to the brake. There was no glue. I always take care to check if the sole of shoe is dry and not slippery. The tip to use self adhesive emery for skateboards is an unvaluable help (and so plausible).
