I have have a brake indicator light on the spedo it doesn't light up. is this for the e bake or something else? thanks
You sure they had that on the early squares? My 75 doesn't have any kind of switch or wiring on the parking brake. I think the light only comes on when the proportioning valve senses an imbalanced pressure in the brake system. I'm no expert, but I'm fairly certain the 73's brake warning light was only for the purpose of indicating brake failure.I think it's a single wire going to a small switch that has an exposed copper contact on it. Held in with a single screw, back tucked up near the firewall on the e-brake mechanism.
My 75 is the same as yours. No switch no wire. Light just comes on when brakes are outta whack.You sure they had that on the early squares?
