Brake Lights staying on
 

working on a lady-friend's car (1991 nissan stanza) and the brake lights stay on. there are 2 switches off the brake pedal and fortunately i did take the correct one off. it is a good switch. i even plugged it into the car and pressed the switch and the brake lights went off.
did an internet search and found that it is common with these models that a grommet that is on the pedal will deteriorate.
i screwed the nut on the threaded part all the way down but the lights still stayed on.

i have found it very difficult to work under the dash (as almost all cars are) and would like to hear if someone has done that job (the part is 3 dollars at the dealer). i dont see how i am going to get into there.
Is there a workaround?? another switch that is longer??
i could take a round piece of metal and drill 4 holes into it and secure it into there with tie wraps (i guess ??)
thanxs in advance for any response??

very few into this (??).
took the front left tire off and opened the bleeder screw.
cut a small board and wedged it on the right side of the pedal - from the pedal to the underside of the dash
worked under the dash with my body closest to the left side kick panel.
used a 1/4 bolt and nut - put that into the hole. while using wrenches to tighten, the other plastic button (that better describes them) fell off; got a 1/4 inch bolt for that one - put a lock washer on this one. i did not take the other switch out - so hopefully it is working ok (dont know - i think it is for the cruise control).
sized up the setting for the brake light switch and set that into place.
this has been one of THE toughest jobs i have ever done.
