Brand new, unused.
Made by ATE who make the genuine Volvo calipers and in effect, these are identical to genuine Volvo but "Volvo" has been ground off in two areas and the piston seals don't carry Volvo branding.
Some manufacturers do this on cast parts when their aftermarket part is identical to genuine.
These are bare calipers so don't come with carriers, guide pins or pad retaining springs.
I have no idea what Volvo charge but doubt you'd get much change from £500?
Postage is extra and expect it to be expensive as they are heavy so collection or meet in Cheshire is possible also.
£280 for the pair but all offers considered and you never know your luck.
