On a bracket bolted to the bulkhead above the brake pedal, when you push on the brake pedal the plunger is released making a circuit and the brake lights come on.
If the switch faulty your brake warning light can come on.
Evening all,
Hoping someone can point me in the right direction - the brake warning light has come on on the dash of my 1990 Defender 110 - I've checked the handbrake, that's working fine, and I've checked the brake fluid levels, they all seem...
So my 200tdi is shagged, and I considered sorting myself, but in the end I've elected to have a pro sort it for me and build me a new one. Peace of mind of a proper job without mistakes and getting the wheels turning sooner drove me to that decision
