'GC - Emergency Brake Light always on...
 

'94 GC 160k miles.

Dash emergency brake light indicator always on.

Pulled armrest box to get to switch at emergency brake arm. Cleaned
and adjusted to ensure contact. Light still on whether brake on or
off, whether terminal is on or off at switc.

Thought appreciated. Thx

It's probably not the E-brake switch; more likely the differential
pressure switch in the master cylinder, indicating partial hydraulic
system failure. This is not a good thing and should be remedied
quickly. Sometimes these switches must be physically 'reset' after a MC
problem has already been repaired. You can check this by pulling the
wire harness from the switch to see if the light goes out.

The big red BRAKE light comes on if the parking
brake is on -or-

1) There is a leak in the front or rear brake
system and the proportioning/safety valve has
shut down that side

2) brake fluid is low or brake linings are
almost worn out.

I'd start by checking the fluid level and then
the disc and drum brakes for wear or fluid.
