Default Parking brake help

My 55 plate 2.4 163bhp XC90 failed its mot on a few jobs including the parking brake. I have done all of the other jobs but am struggling with the parking brake. I stripped it back and the on both wheels one of the parts where the retaining springs attach has come away so the brakes will not hold their position so the new shoes catch when driving and have very little grip at all. The old shoes where not even attached anymore. Is it a new backing plate I am looking for or something else before I concede and send it for spares repairs.

yes a new baking plate is the ideal answer unless you are handy at making up a suitable spring retaining shape to weld on .. you must get the spring retainers off before removing the shoes .
Use VOLVO shoes , the poor quality ones wont hold very well also new discs and make sure the expanders are free which the cable attaches to through the backplate . bed them in for a while by gently applying the brake at 30 mph for 30 yards or so release to cool down do it a few times ..readjust and see how it is it should hold on the 2nd click when all is properly adjusted and good .

That must be new, VIDA says four or five clicks, but IIRC there was a bulletin that stated six or seven would be better (to avoid these falling apart shoes).

All the xc90 parking brakes i have overhauled have stopped nicely on the 2nd or 3rd click when adjusted up and bedded in . so why would you want less reserve travel which the lever must have to pass MOT.

I don't want to, VIDA says it and that's why I'm asking.

As I said, I do remember something because of the falling apart of the brake shoes/pads. Something that more space between the pads and the disc would be better heatwise.

But that was more ten years ago, and my memory isn't that good any more...

All of the above and you must check the surface in the inside of the drum/disc where the friction material comes into contact - if it’s corroded or has been corroded and it’s dull and shiny then they need to be changed as well. Polished rust is much more slippery than bare steel.

I’d also reiterate the point on genuine Volvo shoes, they’re not expensive and based on 6 years of reading about XC90 brakes on here you have a much better chance of success with them.

I also had this same mot problem, and saw online the adjustable spreaders that are available (on ebay) for about 15 quid. So I renewed the lot, discs, pads and shoes (eurocarparts I'll confess), and fitted the adjusters, and it is about as terrible as before. The garage managed to get it to pass-level efficiency, just, but it seems there's some fundamental problem, when every other car I've owned with this system hasn't had this issue...

Yes there is a fundamental problem, but I don't know what it is. The design seems to be the same as other Volvo models but the efficiency is only poor at best. However it does seem that it is vital to use genuine Volvo shoes to get any decent performance.
