2006 XC70 front rotor size

Thanks for the replies guys. Brakes don't seem to be dragging. This is our son's car and I thought maybe he was riding the brakes or tailgating (therefore needing to brake hard) but having driven with him it doesn't seem so.

The car has been hard on brakes since we bought it from the local dealer in 2011. At that time my wife was the main driver and I know she drives well. Brakes show no signs of over heating and after the 3 early sets of front and set of rear warping, they have settled down but still give lousy lifespan. So far these have not warped.

I am newly returned to Volvos, so I may be full of it here -- but is there a brake proportioning valve of any sort and if so is it maybe faulty?

hello,

I have a 2004 xc70... my wheels are 16 but when i measure my rotors they are 280mm (i didn't take the wheel out so i assume the proper measurement is more like 286mm). Now based on what you guys are saying, this shouldnt be possible.. right? having 16 wheels i should have 305mm?... in any case... if i wanted to replace my front rotors, would i be safe ordering 305mm with my 16 wheels even though i have 286mm right now? thanks for any tips

Volvo put the 280mm rotors on your car. That’s likely what you still have. They fitted 280mm rotors to the XC, base models, and 2.4T models. That’s the standard size.

Volvo fitted 305mm rotors on the T5 models. They’re an upgrade. Those rotors will fit under your 16” wheels, but you will need the caliper brackets from a T5 to position your calipers to fit over the 305mm rotor.

As I said in my post below, it’s an easy swap. I’ve got 305mm rotors on my wife’s XC. I bought the T5 (larger) caliper brackets from Rock Auto for about $20 each. Bought a set of 305mm rotors and new pads.
