Rear Brake compensator

Hi all - brakes not made it through MOT and garage recommended I look for this part... any ideas of where to get one? Is there a compatible part on another model? Mine is the 02 bus version.

Thanks all

If you have a quick search through the forum you'll see it's not a difficult job to strip and clean your compensator valve for a free/very cheap fix. Someone on here did have a spare one a while back but can't remember who, sorry

Hi - still no joy on finding a compensator so the search continues. If anyone has one please shout. Thanks
