This is a job i have been meaning to do for a long time. i have had trouble heel and toeing on my S2 K series Elise. The brake pedal when pushed hard was slightly below the level of the throttle pedal. This made easy H & T hard. You had to twist your foot to a funny angle to do it.
I had tried adjusting the throttle pedal to sit lower however when i did this it prevented me getting 100% opening of the TB butterflys. I decided the brake pedal needed adjusting. After a quick look at the SELOC tech wiki i needed a 17mm and 10 mm spanner to do the adjustment.
Now i have a fixed race seat and decided to be lazy and not take it out to do the job ( first mistake ) as im 5 foot 9 its quite close to the steering wheel. So it was roof off and assume the Lotus position with my head in the drivers footwell.
It was at this point i realised i had the wrong tools. I also realised i was stuck. I eventually removed myself by pulling on the steering wheel and honking the horn unintentionally a few times. it turns out you need a 3mm allen key and a 10mm spanner on a S2 K series.
I decided to do the unmanly thing and read the manual before another go. It turns out the brake pedal should rest on the pedal box scuttle flange ( ohh err ) and then have half a turn of preload on the pedal for it to be adjusted correctly.
When i assumed the position again my pedal was about 2mm from the flange. It only took me about an hour to get at the locking grub screw and get it right. The techwiki was for a Toyota car. The good news? Its now perfect for H & T and the brakes appear to work better If you are struggling with H & T on your S2 K check the brake pedal adjustment. Have fun.
