any help with brake light switch?

Can anyone tell me where the switch might be that activates the brake lights?. I have turn signals,driving lights, and have current to the light assemblies. I have replaced all bulbs so I know that not it. Is there a pressure switch somewhere near the master cylinder perhaps?..any help would be appreciated
Thanks,

Hi

On my early +2 it is a pressure switch mounted into the 3 way split in the brake pipe. You can see it if you look through the right hand front wheel arch. It looks like the pic attached.

On the later +2 the mechanical switch is screwed into the rear of the pedal box and can be viewed from the engine bay.

Hope this helps

On my S4 it’s a mechanical switch operated by the lever on the LH end of the pedal shaft inside the car. See pics.


jason and rodger,
My thanks for your help…i ask a question and not only get an answer but with pictures as well…I love this site…what a great resource.

Will check the switch as soon as i can figure out how to wriggle under the foot pedals and have a look.
thansk everyone,

Hi

Couple more pics for you:

Late pedal box arrow points to where the mechanical switch screws in.
