Why are there 2 brake light switches?
 

My brake lights have stopped working on my car.

I see from previous posts that the switches on the MC are a common fault and easy to replace.

But, does anyone know why there are 2 switches on the MC?
I am guessing its a fail safe method in that if one fails the other should work.

When mine failed I had no lights on the dash that came on or anything - any thoughts?

Many Thanks

Rich,

I think you'll find it's one switch per brake circuit, don't forget we have dual master cylinders.

Cheers

Hi Tim,
Do i need to change both switches then? Or could it just be one causing the problem?

I replaced them both 'while I was in there', they are cheap.
