74 duster brake light switch
I am just trying to diagnose first before throwing parts at it, thanks
I normally agree, but sometimes that gets to be "too much."
There's only so many things................
a gummed up switch, stuck. Very likely
Differential pressure activating the switch, what can cause THAT
You have a good hard pedal? Any leaks? If this part is OK, then it's not a leak per se, or shoe adjustment
Do the brakes actually seem to work well?
That would seem to indicate a stuck switch
If you refer to the service manual, you get into hydraulic pressure checks. This is messy and time consuming, and in this day and age, not only are inverted flare fittings and adapters somewhat expensive, but many parts store people don't even know what they are
You might get two people and try "gentle bleeding" of one side or the other of the switch to "joggle" the piston inside.
FRANKLY if the brakes work well-------go out in a deserted area and really get into them, I'd pull the wire off and would not look back.
I've had 3 brake failures that I can specifically remember, one on my vehicle, two others on friends cars. IN NONE of them was the warning light "any help." I already knew from "what my foot was doing" that "we" have a problem
