Found out last night that although all of my lights work if I only light use the brakes (feather them) there are no brake lights. Can I make my swith that is on the pedal more sensitive? If I quickly apply the brakes they light up no problem but if I use them by slowly pushing the pedal to the floor the lights do not come on. I figure that the switch is causing this to happen.Thanks in advance for any and all info/suggestions. Richard. ------------------

sounds to me like the switch is sticky. Don't know if you can lubricate the plunger or not but I'd try it.------------------

I agree with Mike. Try a little WD40 on the plunger. If the lube doesn't free up the switch plunger enough, you can replace the switch without too much hassle...If the plunger is working fine, but just doesn't react quick enough for you, I suppose you could (somehow?) extend or lengthen the switch plunger so that it contacts the pedal quicker/sooner...?

I'll take issue with that! If the 66 switch is like the 68 (I think they're identical), and you stick to the original assembly involving two nylon washers and a plastic bushing, I'd call reinstalling the brake pedal with a new switch attached a tricky little SOB!
The switches are at least cheap and readily available.[This message has been edited by Fastback68 (edited 09-15-2006).]

Keep in mind that brake switches are slightly different between manual and power brakes. One is more sensitive than the other...can't recall which is more sensitive, but it's probably the power one. If you use the wrong switch it won't behave correctly.I found this out when I switched from manual to power brakes. ------------------

To the best of my knowledge my car has always been a manual brake set up. The car used to be a 3sp and is now a auto but I still hvae the manual pedal. I don't think that is a concern at all. I figure the switch my be old and dirty and just not so sensitive. I hope it is not a pain to fix.Richard.

Richard,
