914World.com _ 914World Garage _ brake light switch

Posted by: xsboost90 May 17 2005, 05:40 AM

so i searched and looked in my haynes manual which tells me absolutly nothing and i cant find if there are more than one brake light switch or what. There is the one on the mc in the haynes manual, that one is brand new on my 19mm, but the lights arent working when i press the pedal. Does the e-brake switch need to be hooked up, i tried grounding it but still nothing.

the brake light switch (there is exactly one) is a microswitch in the pedal cluster activated by the brake pedal.

( Haynes, p 129 )

the switch turns the lights off. (IOW - if it falls of or something, the lights will turn on.) but it's possible a lead could have come adrift.

pull the pedal board (4mm Allen, i think...) and check out the switch.

the switch(es) on the MC are only for the dual cylinder failure BRAKE warning light on the dash.

It's a funky set up. If my car was here, I'd go take pics for you. It's mounted between the accel, and brake. Little black box with an arm hanging out. Looks like this...

the switch on the MC of which you speak drives the "BRAKE" light on your instrument cluster... when your emergency brake is on it should come on, and when your M/C is failing it's supposed to come on... some of these have 2 wires, some have 1...

ah ok, so i misread the manual. Ill check that, my pedal board is still out. I may have yanked a wire off accidentally when i did the mc or something. THANKS!

edit- actually now that i think of it, they may be on all the time and i was thinking they were running lights. Perhaps my pedal just needs adjusted up some.

As an aside; When you install the brake light switch, or anytime you are messing with the cluster, the switch arm is OFF in the forward, cocked postition.. I have bought two project cars with the switch arm placed behind the pedal arm. Wrongly.

That's EXACTLY what I was banging my head about for a couple of hours the other day. If that little elbow isn't bent over the nut on the brake pedal, they'll be on all the time.
