Brake activated windscreen wahser

[Andy T]

Hey all,

It seems I got myself a possible world first, a Brake activated Windscreen Washer Jet!

Took my car to back to the dealer I got it from the other week and asked them to look into why the washer bottle keeps emptying itself without actually being used. They came back and said that it was just the hose had come out of the bottom of the filler bottle. Not convinced that was the problem because a) I'm not a numpty and I did already check that and b) now when I go downhill and use the brakes, I get a big squirt of water from one of the washer jets all over the windscreen! Not so good when you happen to brake and want to still see where you're going!

Anyone had anything similar happen to them? Car is an '03 S2 111S

I could take it back to the garage but it's miles away and the last couple of times I went to get things "fixed" they turned out not to be fixed at all!

Loose wire on the washer pump so every time the nose of the car dips, it fires up?

Either that or someone's wired up the brake light switch to the washer pump!

The amount of jet spray is related to the braking force (or should I say the rate of deceleration). So it seems more likely to me that water is being pushed through from the washer bottle when braking somehow?

I need to take off the front panels and have a good look.

Had exactly the same issue on my Exige. It was a non-return valve that had failed right up near the screen. If you take the front access panel off (can't remember which side)you will see it conncted to the pipe. Simple to replace and pennies form a dealer.

that sounds like the thing! Excellent. Thanks for the info. Why go to dealers when you've got pistonheads eh?
