I need to increase the sensitivity of my brake light switch. I have an obp pedal box.


Can anyone help?

Put it on the front brakes, not rear. Put the switch under the brake line so it doesn't trap air.

I use one of these, seem to be far before sensitive than the switch I used to have. Substitute one of your master cylinder banjos for it.

Think the problem may be that I've recently changed the fluid so may have inadvertently trapped some air. I'll take a look tonight and see which way up the switch is pointing.

Size of the switch is m10x1 tapered.

Be careful screwing it in. Being tapered it can split the T piece if you over do it. Some suppliers will send you 1/8" ntp 27tpi as is very close. But not exact.

Sold for the good old mini, mgb and many others.
