Brakes: - Compatibility question

grahamk998 · May 30th, 2012, 14:11

Rather annoyingly I've been a bit rash to acquire some 336mm front discs although these are genuine Volvo they are part number 30769057; and once I belatedly decided to look up the part number I found out that they are described as being for an S80 (2007-), V70 (2008-), or XC70 (2008-).

Hence my question are they suitable for i.e. interchangeable with 336mm front discs for the XC90, part number 30657301?

have you tried calling a local dealer to check the part number to see if its compatible with XC90?

I'm not an expert but i changed my XC90 and S60 discs late last year.
I've got a horrible feeling that the XC90 ones are 336x30, and the S60/S80 are 336x28 so might be too thin. I don't know if that would cause a problem or whether it just means the caliper piston pushes out more. Or whether they are too thin to stand the punishment of the XC90.
