hi i restored my galaxie and i,m almost done ,the problem i,m having is my brake lights stay on all the time ,i put a new switch on and it is the same ,if you pull up on pedal with your hand the lights go out but a mechanical adjustment has to be made somewhere i just don,t know where please help

What work did you do to the brake system? Did you change Master Cylinder? If so it could be a problem with the length of the push rod. May be just a simple adjustment of the brake light switch position though. Someone will chime in here soon that knows about this. Be patient

I dunno, but dont recall a pedal spring on mine- the switch is kinda 'weird' to me as it always seems to have weight of pedal on it, yet only pushes offcenter on the pin a little to turn on lights...I think if the pushrod length were too long, you would not be able to pull up on the pedal to shut it off? Id say if theres no pedal spring(dont recall for sure, but dont think so) the new switch might be bad too?

heres a pic of the switch assy from the manual- perhaps its flipped over, or a bushing on wrong side?

guess there is an adjustment:

sorry for the pics- scanners broke...good luck with it

if you cant read them, right click/copy/paste into paint or something where you can zoom in a bit- funny they look clear as a bell in other s/w, but hard to see as posted...

I had a similar problem when I replaced my master cylinder and booster with a brake kit. the flat part of the rod that butts up against the switch was just a touch too thick keeping the switch closed all the time. I had to grind a little off of the push rod on the surface that contacts the switch (flat part indicated by the red arrow) to keep the brake lights from being lit all the time (switch closed). If you end up grinding just a little to much off and the lights won't work when the pedal is pressed, then you can tweek the switch surface indicated by the blue arrows towards the rod so that it lights when the pedal is pressed. I ended up doing just that. My switch and lights work perfect now. Thank's ford4v429 for the picture!
