Brake system warning light - test switch
The SVA says that the brake system has to have a wrning light that can be tested - can anyone explein what they mean and hos to do it? I have a master
cylinder off a capri with the sensor in the reservoir cap.
Thanks

Hi Gary
The brake warning light, tests the brake fluid level, to ensure you have enough in the resevoir to stop you!
By tradition in most tin tops this is done via the hand brake. i.e. you get in turn the ignition and the warning light comes on. If it doesn't
you should check the bulb and the brake fluid level before you set off.
So briefly run a switched live from the ignition to the warning light, then from there it has two routes to earth to complete the circuit, one through
the switch on the fluid level cap and the other through the test switch (normally on the handbrake).
(NB It may need wiring differently depending on the way your specific switches work)
 
for rob
Hope that helps.

It means a method of testing the bulb in the dashboard.
Easy:= Just wire up the handbrake switch, and applying the handbrake will test the bulb, as well as telling you your handbrake is on.
Somtimes its much simpler than you think
1. The point of a journey is not to arrive.
2. Never take life seriously. Nobody gets out alive anyway.

The best way imo is to have a switch which is activated by the handbrake connected in parallel with the 'low level' switch on the m/c cap.
That way you can test the warning light (on the dash somewhere) by pulling up the handbrake.
Cheers,

When thinking outside the box doesn't work any more, it's time to build a new box

For the benefit of others - the button on the reservoir cap isn't enough on its own - it has to be something the driver can do in the passenger
compartment. In your case you're OK as you have a switch on the handbrake. You can have a push-button on the dash, but I believe that it has to
be labelled to show what it is (the handbrake is tidier!).
I got my handbrake switch from Premier Wiring - it's like a microswitch with a broad lever on it. Wasn't expensive, and all I had to do
is make a mounting on the base of my Escort handbrake, and a bit of angle on the lever to contact the switch. It's all hidden by the rubber
surround, so it didn't bother the SVA man.
cheers,
David

interesting, one would have thought that unscreewing the cap and lifint it out of the fluid would be enough.
On mine, I have separate switch on the dash with red brake symbol on it.

You dont need to lift the cap off the resevoir to test it. The top of the cap is a button to check the operation of the float switch.
Agreed, the easiest way is to connect up the handbrake switch. And yes it needs to be testable from the driving position (sure it says that in the
manual somewhere)
