Re. idiot light, the complete situation was that the car was leaking brake

fluid. They brought it into the shop and found there was a leak in the
brake 
line in the front of the car, which they repaired. That stopped the leak
and 
stopped the light from coming on.

Right now there's no light that's coming on, just some fluid leaking out
of 
the rear wheel cylinders into the drums. But not enough for the light to
go 
on.
