Brake Fluid Level Switch

 The brake fluid cap on my Caterham leaks. I have spent a good bit of my free time this week completely over-engineering the replacement. It's easy enough to go and buy a genuine Girling cap and I have every faith that it will seal tight, but it doesn't have a fluid level switch for the warning light. I also bought a very high quality float switch from Compbrake Motorsport. Then I just had to work out how I could fit the switch to the cap and connect it to the car in such a way that you could unscrew it without tangling up the wires.

Stock.

Roughed out.

Close enough to final size

Marked out a rectangular hole

Cut the hole

Bent up

It's a mounting bracket for a very high quality, waterproof, quick release two pin plug.

Drilled the cap

Drilled a new breather in the cap

New float switch

Electrical connectors for the float switch

Float switch is now inside the reservoir, the plug and socket is mounted on the firewall.
