Does anyone know what this spring is called?

[paulmlpss]

Hi all have just changed rear flexi brake hose on the offside and noticed a small spring dangling about. Think its something to do with the brakes and how much weight is in the back of the van. Anyway it has snapped and just dangling about so need to get a new one but dont know what its called. You can see it here on the photo http://www.ebay.co.uk/itm/PEUGEOT-PARTNE...1789482836
Any help much appreciated
Thanks

Is it a brake compensator spring?

Citroen won't sell it seperately but if you search the net there is a site selling them seperately.

Make sure when you fit it that the valve isnt siezed.Pleanty of WD40 around the valve works wonders,then some good multipurpose grease to keep it lubricated.Its an MOT fail if its siezed or very stiff.
