John E Posted August 25, 2000 Share Posted August 25, 2000 I can almost see the replies, you dont brake in a 7, brake less, use the box, dont worry about those behind they wont catch you any way but my brake lights only come on with significant pressure on the stop pedal. The car is 1990 with a pressure switch in the braking system. I've heard that there is a more modern type of switch available, is this true and how much and from where. I really dont want to take the original out unless its absolutely necessary. Link to comment Share on other sites More sharing options...
Andrew Russell Posted August 25, 2000 Share Posted August 25, 2000 John, My car has a mechanical switch fitted inside the pedal box and can be adjusted for sensitivity rather than relying upon pressure in the system. Probably a straight forward upgrade for a man of your abilities.....I'll pack a screw driver and I'll show you mine on Monday. Andrew. Link to comment Share on other sites More sharing options...
CHRIS CLARK Posted August 26, 2000 Share Posted August 26, 2000 Is this a "If you show me yours, I'll show you mine" situation? Link to comment Share on other sites More sharing options...

JKJ Posted August 27, 2000 Share Posted August 27, 2000 I had a similar problem on my '91 supersprint. I fitted a motorbike mechanical switch, locating the switch body in the pedalbox, and attatching the acctuating spring to the brake pedal. Works perfectly and allows fine adjustment by screwing the switch in and out. Link to comment Share on other sites More sharing options...
fastforward Posted September 21, 2000 Share Posted September 21, 2000 John, what did you do in the end? I would like to think the pressure switch could be "maintained". I have the same problem but would like to correct the the current arrangement. Brian brianfyfe@ema.org.uk Link to comment Share on other sites More sharing options...
Asklepios Posted September 23, 2000 Share Posted September 23, 2000 Buy Caterham`s adjustable make-or break switch which fits inside the pedal box.Permits even feathering the brakes to activate the lights.The hydraulic shuttle valve is not so sensitive and requires a firm push of the pedal even when fitted bang on horizontal.

John E Posted September 24, 2000 Author Share Posted September 24, 2000 Brian, I simply changed the switch for a new one and according to those who try to follow me the brake lights are now working. A further upgrade would be a simple electrical on off switch which I would have to attach to a bracket on the plunger itself. There is no obvious fitting facilty on my 1990 car so it would be an"inhouse" job. Best of luck. Link to comment Share on other sites More sharing options...
Asklepios Posted September 24, 2000 Share Posted September 24, 2000 The Caterham kit is complete with mounting bracket and a 10 min.job to fit.I wouldn`t bother fabricating my own. Of course you leave the original switch and simply lead the wires into the pedal box.I fitted them between two small strips of old neoprene to stop chaffing.You could use silicone instant gasket.
