<< The "Push to Test" switch on the dash only has one function: it tells you
the warning light bulb is not burned out or otherwise not working. The
actual brake failure switch is located on the brake fail warning assembly on
the right side of the engine bay (it's the brass part where all the brake
pipes converge). There is a shuttle valve inside this assembly that
activates the switch to turn on the dash light if the valve is not centered
(as would happen if you lost one of your brake circuits). If the light is
staying on, it's probably because the shuttle valve in the brake fail
warning assembly is not centered. To turn it off, you have to loosen the
bleed screw on a brake while a helper applies pressure to the brake pedal.
If you have identified the proper circuit, the light will go out as the
shuttle valve moves through center. When that happens, tighten the bleed
screw. If you don't time it right, the light will come on again, so
coordination with your helper is important. >>

A good description, Steve. Two points...the push to test light is not on the
'77 Midget. It is just a light. Also, it is less confusing to give engine
bay directions (or any locations on part of a car) as though you are looking
at it from the driver's seat. The pressure switch is located on the left
inside wing (fender).
