I'm a spirited driver, and i'm going through brake switches about once a
month. They are of shithouse construction and only designed for sedate
driving. Slamming the brakes on regularly destroys them fast. Genuine Ford
and aftermarket, no difference.

Is there a decent alternative or is it possible to install any other kind of
brake switch because it alone is really starting to give me the sh.ts.

I don't want to sound anal but why don't you just drive a bit more like Miss
Daisy.  I am sure you will save time and money.

so your confirming the believe that fords have to be treated gently and cant
take a beating ?

Fords can take a beating, mine has done just on 500000 kilometres and the
brake switch is still working.

brake light switches are a problem, but nowhere to the degree you are
experiencing. Mine was replaced once at approx 145,000 on my old EF
XR6.

Maybe something has gone missing or put back incorrectly, I vaguely
recall it is easy to put the nylon spacers in wrong?

if you hit the brake pedal hard, the nylon bush crushes and it damages the
brake switch, an obvious solution I think is a brass bush. Any volunteers?

A brass bush sounds a good solution. But I would still question why
its chopping out the nylon bush. Isn't there 2 nylon bushes, a left
and right?
Bill - 19 Nov 2003 09:44 GMT
no, they are spacers, a blue on the right, and a green on the left.
there is a nylon bush thats inserted into the brake booser plunger to lessen
the looseness of it, when on the brake pedal shaft. basicly, this nylon bush
is what f.cks up the brake pedal switch. Tisnt the contacts burning, not
ware or tare, eventualy it bends the metal sprung plate in the switch and
gets the contacts out of whack. If this bush was brass and couldnt compact
this would never happen and the brake switches would last a very long time
as they are supposed to.

An obvious solution is to remove the nylon bush. I've done that and not had
a single issue with the switch in my EL.

Prior I'd had 2 switched die in 180,000's.

I ripped apart my brake switch and bent and twisted the contacts so there's
only a 1mm gap now, just breathing on the brake pedal makes the lights go on
now. Its worked well now for 2 weeks, and has not died yet.

The worst part about a screwed brake switch is that the cruise control
doesn't disengage, the car accelerates to maintain speed when you put the
brakes on, pretty dangerous really.

That sounds odd, my EF XR6 didn't even let the CC engage when the
brake switch failed, there is a pressure switch on the master cylinder
thats used to detect brake application iirc.
Bill - 24 Nov 2003 04:35 GMT
thats right, but it takes significant pressure on the pedal before that cuts
it out.
