On my 940, if I recall correctly, there was a solenoid at the base of the shifter. When it was in the 'correct' position I inserted a tiny sliver of metal that would prevent the sliding part of the solenoid from returning to the locked state. I figured that if this was a bad idea I could always remove that sliver. This was about seven years ago. I can't really remember if this solved the problem with the brake pedal or the shifter not moving but maybe the sliver idea will work for you.
