There is a blue warning light that says "cold". What would this possibly be telling me that I wouldnt know? I also am not finding a brake system warning light or sensor for that, is it where I cant see it ? Where is the sensor? I wanted to incorporate the warning switch on the proportioning valve I am putting in for the disc swap

The cold light should light-up after you start the engine and remain lit until the engine reaches operating temperature. The 65 Ford did not come equiped with a brake system warning light and sensor. The brake light and sensor were installed later in the 60's or early 70's.

Shadow.

My 66 Gal has this light. It illuminates when the emergency brake is applied.

I think the light v8shadow mentions is the light for a failing in the master cylinder or elsewhere in the brake system.

Yeah, hydralic brake pressure failure. There is no sensor or light. It is just to old for that yet.

 

[wildosvt01_OLD]

Gotcha.

I cant see it being that hard to adapt something from a 78 bird or something.

Any ideas on how this could be done?

I have a 65 (power drums) also and would like to switch to a double reservoir and b.) get one (or get a lid for one) that I can rig up to a low-fluid warning light on the dash.

the differential switch or whatever they call it that goes under the master cylinder with the two wire plug should be all you need for PRESSURE loss if one side develops a leak, I put one in our 65(actually borrowed it from my 69 mustang...) but never wired it to a light yet...
as far as low fluid, newer cars have a floatswitch of some sort in the side of the reservoir(my 06 mustang does anyway) to alert you to low level before it gets low enough to lose pressure... would be hard to do that without the bigger plastic reservoir- but they are made for at least front discs(if not also ABS), and wont have residual valves for front drums...

Thanks I didn't know what triggered the warning light. Is thia what you are describing? Fullsize Page 3 of Brakes 2008

I saw your rebuild log, man that was a lot of work.

If this shows up right, you will see a typical brake prop valve system cutaway. See the little switch in the center. It sits above a piston that is tapered in the center. If pressure drops in either the front or rear, the piston will move in the direction of the area where there is a drop in pressure, being pushed by the area with more pressure. Once the piston passes that switch pin, the taper starts to push the switch pin upwards and make the connection in the switch, triggering the warning light.

I have a single bowl, so a pressure differential between the front and back is pretty much non existant. I was thinking about a fluid level sensor, maybe something like Plastic Float Level Switches - FS12
where you could drill a hole in the top of the MC cap and install the sensor.

What do you think? and where could buy just one, not 1,000.
