S1 XJ6 brake warning lamp

Good morning all,

1972 XJ6, daily driver.

Brake warning lamp on the dash decided to light up on this mornings start up.

Brakes work, plenty of fluid in the reservoir, e brake handle seems to be fully seated down.

Not noticing any fluid loss anywhere, mind you it’s still dark in LA.

Any obvious culprits to this I’m missing?

Best to all

Hi CDS - brake warning light on the Series 1 only indicates fluid level in reservoir and parking brake being on. Check your parking brake handle for being all the way in and it’s switch/wiring, check the wiring to the brake reservoir cover. Check that the little float in the reservoir isn’t hung up too.

Best,
