Jack up, remove wheel, prop up on axle stand - all ticks.

Undo bolts for caliper slides, with no need for twist bits - ticks.

Remove pads and put caliper out of harm's way - ticks.

Remove caliper yoke bolts - pass the Laser bits please. Application of breaker bar to socket and the yoke bolts budged - more ticks.

Remove hub cover - pardon? How do you remove the hub cover without destroying it?

Put the brake system back together; I KNOW the yoke and slide bolts are use-once items but the Valdez is going nowhere and I'd rather have it on 4 paws than three paws and an axle stand.

You can buy new from the dealer but they do straighten out if you crease them too much

Good to hear you made some good progress - for hub cover i'm assuming you mean the dust cap that simply levers out from the centre with a large flat screwdriver or similar - alternatively a few delicate taps around the circumference of the dust cap with a screwdriver/chisel/punch away from the hub usually shifts it.

*** EDIT *** Mark beat me to it and included pretty pictures to show the same as i was saying. :thumbs_up:



Slide bolts i believe are reusable, yoke bolts are only single-use only because they are patch bolts. Clean the threads of the old thread locking compound, refit both so the caliper is secure then remove one at a time, add a few drops of Threadlock (i use Loctite 243) then refit to the recommended torque (100Nm/74lbft rings a bell but would have to check), move on to the other once the first is tight and the caliper won't move and repeat, job done.

"Hub cover" is the dust cap; I now need to get out the robbery kit and buy the yoke bolts, backing plate bolts, caliper bolts and a replacement spigot bolt - the one that keeps the rotor and hub together as I watched the old one disappear before my eyes. Unless someone has a spare they no longer need?

I might have one kicking around. I can see when i get in. I might also have some dust caps and some nice shiny bolts for the backing plates

Realised yoke bolts are caliper carrier bolts ! 10mm allen key head

Appreciate your looking. If you have them I'll take them off your hands.

I thought about applying violence to the dust cover but my neighbour's on a 2am start and wouldn't appreciate the noise of an impact generator.

just double checking that it's one of these that you need https://www.skandix.de/en/spare-part...screw/1013799/

That's the very item; but 12 Euros for a single screw strikes me as slightly extortionate. If I knew the thread pitch I could probably buy something suitable off the shelf for a small fraction of that!

Even more extortionate when I learn that the caliper yoke bolts are 3.60 Euros each.

I wonder what Volvo would charge for the real thing? :thinking:

Probably cheaper from FRF with VOC discount

I'm waiting for Clive Brook to get back to me with prices.
