Sticky Brake Light Switch


Paula W
 

On my 1947 sedan the brake light switch activated by the brake pedal is sticky, so I am sometimes left with the brake light on when the engine is off.
Can I service it? (clean, lubricate...etc.)

I would use some other kind of spray lub that is recommend for electrical contacts. Don’t remember the number right now but it is made by CRC. WD-40 may work initially but can gum up things after awhile.

Could it be a return spring issue?

I look at it again with that in mind, but I don't think so. I seem to recall the spring looking in pretty good shape (taught).

I would wait for one of the times where the brake light is still on, and then pull back on the brake pedal. If the pedal moves and the light goes out, it's a brake pedal / linkage problem. If the light stays on, it's the switch. If it's the switch, I would use CRC electrical cleaner, as Jim advised. If it's the linkage, I would clean up gummed / rusted up pivot points with carb or brake cleaner, then spray white lithium grease on them. Also, make sure there is good tension on the return spring.

Thank you. I think I will do all of what you recommend  since I have never done any lubrication on the pivot points.

One question - The brake pedal goes "limp" when the emergency brake (hand brake) is on and to insure the brake light goes out I have to bring the brake pedal up and away from the firewall. Is this indicative of the brake pedal / linkage issue to which you refer? I thought the pedal should be loose once the emergency brake is on.

I'd like to refurbish this brake light switch. May I please have recommendations on what I should use to clean it up? Other than cleaning, is there anything else I should consider. Springs appear strong. That extra wire you see in the photo was used to hold the housing to the mount since once of the little clamps is missing.

Note, this is not the brake light switch from my car and it's "Sticky Brake Light Switch" problem.  I'm finally getting back to my own car's problem with the advice previously given. However, I am hoping to complete this little project in case I need to do this on my car's switch. If I'm successful here, my son will use this on his car.

Meani g no disrespect, but for the cost of a seitch, I'd replace it.

No disrespect taken. I agree replacement makes the most economic sense. However, my interest is in bringing back the usefulness of something old and original and learning a little in the process.


 

I have heard that CRC lectra  clean is a good cleaner for old gunked up electrical parts. Use that to clean, then hit with something like wd40 to lubricate it to make it function correctly. I have also been told NOT to use a Emory board to clean the contacts, because it can mess them up. You can get lectra clean on amazon.

The CRC cleans and lubricates. Regular WD40 will gum things up after awhile, not recommended for electrical or anything with small gears or such. They also sell WD-40 Specialist Electrical Contact Cleaner, I have never used that so it may be equivalent to CRC.

Listen to Jim! A much better person to get advice from than me. I am a student amongst masters here. ( I sure appreciate their help though )🙂
