|
|
My brakes work fine but my friend said my brake lights are not working. When I got home I checked fuse, then by passed the fuse box , by going to wires under the rear seat and they light. So I figure the brake switch. WHen I open the hood I checked the fluid and it is empty. I guess when you get so low the switch does not work. Weird I guess I just caught it because my brakes work fine. I think the leak is before the master cylinder or I would have had braking problems..
Sounds logical. Right???
Also can you change the brake switch and not have to bleed the system??? _________________ email: [email protected]

Yeah - with you on that - probably the reservoir hose - you should be able to spot where it has been leaking. Topping off the fluid should take of the light issue, but if not, you can swap out the switches without having to bleed. _________________ D-Dubya Manx clone - 63 Short pan,1914.

Wait a minute... Filling up the reservoir will not fix the brake light. Those are two separate issues. _________________ I strive for perfection. Excellence will not be tolerated!

The thought on my end was if the pressure was low due to lack of fluid, it may prevent the switch from working.....figure that would be worth trying before pulling the switches..... _________________ D-Dubya Manx clone - 63 Short pan,1914.

I don't know how the Super is configured, but it has either a pressure switch on the master cylinder - or a mechanical switch somewhere around the brake pedal itself. If it has a pressure switch, and it doesn't work because fluid level is too low you won't have any brakes either.
If the brakes work, by all means fill it up but that will not fix the light.
You should be looking for an electrical fault, like a failed switch, lead or similar. I can't be more specific as I never worked on those...
I hope it helps anyway. _________________ I strive for perfection. Excellence will not be tolerated!

It is a weird situation I agree, I get home late from work and have to use a drop light to work, so I am waiting till the week end to fix it.
Like I said the problem is up front, I ran voltage to the rear and the lights work. So I figure it is the switch after checking and cleaning the fuses. When I went to look at the switches to see the connections I noticed no fluid in the bottle. So I would think if the light does not light from low fluid the brakes should not or at least feel bad. Not so they work fine.
But is it just a coincidence, the the bottle is dry???????? Seeing the lines are lower then the master maybe the brakes can work but on on the verge of failure. Or seeing it is a duel braking system and I have discs on all four, maybe one side is not working well but I cannot notice it.
Will let you guys know as soon as I figure it out. Hey if it is the fluid You will know sooner then the weekend because I am going to buy some tonight. _________________ email: [email protected]

Basically if brakes are working good, its not a "pressure" issue (even with low fluid)...
Probable a defective switch(s) or loose/corroded connectors..... Get under car and find master cylinder, and bypass switches if brake lights work, its probably the switches....
Go to this diagram and look for "F" these are brake light switches for 73 Super... Probably identical to all years "super" wiring... And most likely on master cylinder...

I know this is an old post but I now have the same problem. So, how do you bypass the brake switches to determine if they are bad? Do I pull off the wires and connect them to each other? I'm electrically challenged so any help is appreciated. |

Yes you can "jumper" the two wires together and if brake lights illuminate, you have switch problem...
Check wiring diagrams to be sure you get right wires for model year of your bug...

If you have a duel circut master with coresponding 2 switches, and the switch that has pressure is bad and the other circut is bad the car will stop( from 2 wheels) and not turn on brake lights. VERY SIMPLE |

Okay, I'm back. Had to go to work for a bit. I jumped the wires bypassing the switches and nothing. I installed those good looking yet cheeeeep rear tail lights where the brake and running lights are now combined with a dual filament bulb so I am thinking that might be the culprit. but I get no power to the wires leading to the light. Any ideas? And thanks for trying to help. You guys are great to watch this forum and lend a hand. |
