Brake light switch adjustment question

Hi all, just after a little guidance

… the brake lights are coming on if you even look at the brake pedal and so i wanted to adjust them slightly. I read a few posts about accessing them from the front and sliding your hand behind the brake reservoir but i seem to have a rail in the way - does this need to be removed or am i missing something please?

Sadly, yes you have to move the rail with all the Air con solenoids on it to access the brake switch … Ive just done this myself - make sure you mark up the hoses and connections before you pull any off and be careful with that bolt on the plenum don’t over tighten it

Thanks Andy, much appreciated!
