BN1 Mechanical Brake Switch

[Bob_Spidell]

DOT 5 will burn if exposed to hot exhaust gas, like a unsealed seam in a header pipe.

Like most things in life, it's all relative:

"The silicone[sic]-based DOT 5 brake fluid has a higher flash point, while the glycol-based has lower values; hence, they are more flammable."

In terms of installing a mechanical brake switch, The following record sketch(es) is exactly what I did and has worked without any problems for about five years (unless you wear a shoe size above "10" maybe). But even so, I could of trimmed the mounting apparatus to suit a shoe size 12. Nonetheless, this was a solution made possible by having the right stuff available (i.e.- Gilbert metal toy bits and pieces). I offer this solution as conceptual, of course, unless you too, have Gilbert bits and pieces lying around. I do like this primarily because no modification or alternations had to be made to the existing frame or any other aspects to the vehicle as noted as part of my "Design Concept."

Hope this offers a one possible idea. I should also note this worked for my BJ8. I have to assume the existing framework, etc. on your model is identical.

I don't know about the dot 5 vs dot 2/3 affect on the stock switches. I've never used dot 5 but I've had couple of switches require heavier and heavier brake pedal pressure to activate, eventually failing to light when just slowing with light pedal pressure - so I don't think it's necessarily caused by the silicone.

I added a mechanical micro switch in parallel with the stock hydraulic switch. I can't take credit, this idea and switch info came from Steve Gerow (see his blogs). I made some very minor mounting changes but it's generally as Steve shows - the only irreversible thing is 4 sheet metal screw holes to mount the switch. Fits neatly under the dash, inside and dry.
