Just come in and after reading your message sebaveh it now makes sense. Looking inside reservoir can see a center section with something inside it. It moves from side to side slightly but not up and down. Suspecting that this has stuck and is making reed switch conductable - light is on. When I disconnect the wire, light is off.
Do you know if its a serviceable part, that is I will remove brake reservoir, clean out floater and refit it should then work ok or is it the reed contact will be damaged so buy a replacement??
Can do the work myself ok. (Give it a go first out of curiosity)
What should have been a simple brake replacement job has turned into this But hey that's why we love theses T4'S!!
