There is a hissing noise coming from what seems to be the passenger driving seat when ever I take the foot off the break. I have a Peugeot 206 reg y931 jkw
Yup, as said already, brake servo need replacement. These cars being originally designed for left-hand drive the brake master cylinder etc is on the passenger side.

Leaking brake servo. Replacement is the usual solution.

Sorry, it is the passenger dash board, not the seat that the hissing noise is coming from.
