Default V70 2008 front brake pad/caliper types

Hi all

I have a V70 Diesel estate 2008

Last year an advisory on the MOT was for pads, so I bought some shortly after to be ready for when needed

For various reasons it was a low mileage year but set out now to replace the pads before the next MOT

I have changed many pads on various cars in the past but not this car so I watched several youtube videos on changing the pads, I thought I had it nicely worked out and set out today to fit said pads

However on removing the wheels (17" alloys) I find calipers different to those in various videos

The outer retaining clip looks different to all I found on the V70, the nearest I found the same as mine was on an S60 2012

As the caliper looked different I didn't strip it any further, on rechecking the pads for my model the catalogue suggests the one type, but there are two

Eurocarparts online shows one type for Brake system 16" and the other for brake system 16" & 17"

I assume they mean 16" wheels and 17" wheels?

So I suspect I have the wrong type of pads as I have the 16"

Am I right in thinking there is no need to split the caliper?

Backing off the two 7mm sliders will free the caliper to change the pads ?

This was the video with the same or very similar calipers to mine

The two pictures attached are my nearside caliper

Basically yes. Removing the 2 7mm sliders alows the caliper to be split and the pads changed, clean and lubricate the sliders, clean the running channels and measure disk thickness, minimum is 23mm on the vented disk according to my book. If it's likely the disks will be below 23mm by the time the new pads are worn down such that they need renewal new disks are also needed. Last thing you want or need is a disk breaking up.

Last set of disks I fitted to my xc70 were mintex at £65 for the pair as opposed to volvo at £85 each, front pads were also mintex. 18 months on and no problems despite towing and spirited driving.

My rear disks are also mintex at £57 for the pair rather than the £60 each volvo wanted but rear pads are volvo as I had them on the shelf having picked them up at a good price only £3 more than the mintex.

Thanks for that, I was looking for Min disc thickness so that helps also

I should have measured them earlier now I think about it

Eurocarparts want £71.50 for a pair at the present 35% off

Hope I can avoid that

Much appreciate the feedback

You never split the calipers to replace neither pads nor rotors.

Thanks, no I didn't think so either but one video showed exactly that but a comment after said it wasn't necessary

So I just wanted to confirm

Split as in remove the moving part from the fixed part. These are single piston calipers so any splitting is mechanical.
It's terminology and I know what I ment, doing the job it becomes obvious as without a degree of dismantling the new pads could not be fitted.

I have split twin piston calipers to change pistons, all that is required is new O rings and a clean working environment. There is nothing magical about them, they are an engineerd item, understand the engineering and total strip and rebuild as carried out on reconditioned calipers can be done at home.

That's correct. I was just a bit afraid that "split" would be understood by somebody as "split the caliper in half", where I would have worded the correct operation as "remove the caliper from the bracket".

But English isn't my native language, so I may be wrong on how best to describe this operation.

Thanks for the further comments

I understood what was being said in context of my original post

In the video he splits the front of the caliper from the rear by removing the T55 torx bolts, but there is no need to do that, just fully back off the two 7mm allen or hex sliders and the clip

Default Remove caliper from caliper bracket.

To date I always completely remove the caliper from the caliper bracket, allowing me to thoroughly clean the caliper and descale the none swept areas of the disc, inner and outer faces. Measure disc at same time. Only need to remove caliper bracket if disc removal is required.
However, still considering about doing the rears on daughter’s 2010 XC70 with electric parking brake (EPB) as I’ve no previous experience of these. Looks soooo easy on YouTube.

The rear ones are simple to fix, even with electric parking brake.
