To add,

On the cos last night, yellow light and red light came on. Braking fine for a while, and eventually lost all braking.

Noted when turning engine off then back to key position 2, the brake pump was not charging.

Looked at relays behind glove box, and after a fiddle, the pump on retest started to work again. I am thinking electrical. Does this sound like a dodgy relay to anyone?
