Brake pressure switch

[stonedrive]

Hi chaps,
I am after a little help, stag went in for mot, the first one I have put it threw,not to bad front shocks, hand brake cable, rear gaiter rubbers. But there is some sort of switch to do with brakes on the near inner wing, which is leaking brake fluid. Do you know what it's called and even better part number.
Many thanks in advance Steve

It's a PDWA (Pressure Differential Warning Actuator).

If you do a search you should find quite a bit about it on here.

Cheers

PDWA. It is there to warn you if you lose pressure in one of the brake circuits by activating the dashboard warning light. You need to replace the seals inside, which will involve bleeding the brake system afterwards.
