Brake caliper brackets - 06 XC70

Post by **scot850** » 26 Jun 2025, 19:28

I have fortunately not had to by calipers for out son's 06 XC70 yet as I painted them a long time ago and touched up as needed. Car now has about 125k miles on it and I was planning to bleed/flush the brakes but found the rear bleed screws seized.

Long story, but I bought a set of Nugeon reman coated calipers that come with caliper brackets (semi-loaded). I got a 'deal' from Rock Auto on clearance calipers and bought a set for myself and my young friends 02 XC70. In both cases they are listed as having 286mm rotors.

The calipers turned up and only one was actually a Nugeon, the other 3 were relabeled Cardone crap with Nugeon labels on them stuck over the Cardone ones.

I then got a deal on Nugeon ones from a Canadian supplier who could not be less helpful on their website if they tried, similarly their on line help. I planned to buy one front (opposite side to the one I had) and they gave me a part number I needed and ordered it. Turns out the numpty got the sides wrong so I ended up with 2 x left handed calipers. I have just received the correct one for the other side and the plan was to send the Cardone crap back as cores and only use the Nugeon ones if required and keep them on the shelf. I was organizing that today when I realized the caliper brackets have different part numbers!!??

I have since gone down a rabbit hole trying to figure out what it should be as Volvo only lists one bracket and that is for a 17" wheel. Our car has 16" wheels, but how does that relate to brake rotor size. They also list on the 02 V70 XC parts listing a 15" bracket and a 17" one but no 16". The bracket part numbers are of no use as they are reman'd parts from Volvo and they have no cross reference to the original new items. I don't have access to the car until the weekend as I'll have to pull a wheel to find what is actually fitted currently, all I know for sure is the calipers are the same (just as in P80's) it is the brackets that change.

Does anyone have easy access to a P2 XC70 03-07 with 286mm rotors and have their old caliper brackets? The brackets for LH and RH front are the same and the originals have 2 different part numbers stamped on them? Why? one set ends with the last digits -22/-23 and the other one ends in -24/-25. Talk about frustrating as I now can't use the Cardone calipers as cores if the new caliper brackets are the different ones!

I will find out on the weekend but this is driving me nuts!

Oh, and my Vida parts listing has 2 different part numbers altogether for 15 " and 16" and no cross references

So again I answer my own question. So the caliper brackets that came with these reman units are wrong they are for fitting the 305mm diameter rotors and I'm convinced they would not fit inside the original rims as were fitted to this car from new. We bought the car from Volvo in 2011 for 50k miles on it and have since fitted several new rotors due to a Volvo quality issue causing warping, but all were the same 286mm rotors. I tried fitting the brackets incase I was wrong, but it moves the pads about 10mm further out and the pad then overlaps the edge of the rotor.

Why Volvo list the caliper brackets as 15", 16" and 17" wheels make absolutely no sense. As in our case the wheels are 16" and these brackets would catch any balance weights fitted inside the wheels and possibly even the inner surface of the rim.

So if you have to buy replacement calipers, be very careful what you buy. If you just buy the caliper they are the same for both sizes, if you buy the semi-loaded ones that come with the brackets, be very careful to check what is fitted to your car. Below (apologies for the blurry old bracket in the picture) these are the same bracket for LH or RH and have both part numbers on them as such. The only differences are the last 2 digits. For the 286mm diameter rotor it ends in 9209722 or 3. For the 305mm rotors the brackets are 9209724 or 5.

The picture below shows what happens when you try to fit the 305mm bracket. You can see the imprint of the wear face would move outwards if you fitted the wrong bracket.

: Wrong bracket for 286mm rotor

So be very careful when ordering semi-loaded calipers! As I have found several are incorrect and Volvo now only list a bracket for the 17" wheel option and I have no idea what the bracket part numbers that are stamped on it are. Also there is no references for the remanufactured versions they sell v's the original part number options I can find so far.

If you look at the older 2002 XC70 Volvo parts listing I helped with, it uses the same caliper and bracket as our 06 car, but Volvo lists 2 options for the caliper brackets, but again no cross references and even the casting number information in the pictures do not reflect the original ones.

It is never easy. The supplier (Parts Avatar in Canada) is telling me I am wrong and that they have supplied the correct calipers and brackets. I have responded, yes they supplied the correct calipers, (as they are the same) but the brackets are wrong. I have now sent them pictures. I've also confirmed to them these are the same calipers and brackets that came to use with the car from Volvo in 2011. Since then it has several sets of rotors fitted by Volvo (they had a bad batch at one time so we had 3 sets in about 12k miles and a regrind. I have no record of the brake calipers being replaced since new, so they are as far as I am concerned the originals to how Volvo built the car.

If anyone with a 03-07 XC70 has an opportunity to check what diameter of rotors they have I would appreciate it. I have now asked Volvo for help if they can.

Well, I got a replay from one of my local dealer parts department on the brakes fitted to our car. I have the full service history of the car since new so I know the brakes have not been swapped incorrectly:

Hello,

For this one it shows 15” brake/286mm rotors from factory so looks like you got the right front rotors now. As for the caliper retainers I have the following part #s:

8251318 LH
8251318 RH

They all do show up as the same for both sides in current version of VIDA however the part number for this size is discontinued. My aftermarket sources also do not seem to have any new ones available unfortunately. Same situation for the 1 size up which uses the same caliper but this part number I have 8251316 for the retainers.

So they confirmed my car was fitted from new with 286mm rotors. I pointed this out to the parts supplier and the fact if I fitted the bigger brackets the issue is they would remove any internal stick on balance weights....!

They have now asked for the Vin # to confirm is I am correct.......

Well now they are just blanking/ghosting me. As soon as I sent them the information, suddenly they started sending me emails asking why I was not replying. I sent the data 3 times and also through direct means and they closed my ticket and are now ignoring me. This company is worse than useless, and they want Canadians to believe they are the largest and best parts supplier in Canada, yet every dealing I have with them is a drama from their end. Never to be used again. Now off to the credit card company for a refund!
