I'm attempting to change my rear wheel bearings for new ones. It went pretty smoothly at first, until a spring decided to shoot off and now I've lost it!

I was going to just refit the drum and pretend it would still work.

But now I can't get the damn thing back on! Also when I pull the handbrake it's far too slack.

Some pictures below - if there anything obviously wrong in them?

Luckily I've found it! Was right under my nose. Main concern is getting the damn drum cover thing back on. It seems to have a lip, which is making it not want to fit back over it..

Sand it?

Anyway to depressurize the piston at the top which is pushing the pads out? If both the pads were in I'd probably be able to get them back on..

Hmm..

They both push in just fine (the pistons), but what I've figured is stopping the pads compressing is this thing in between them.. (middle arrow)

To the right, underneath the triangular 'clicker' is a thread, like a screw thread. Perhaps if I can tighten this thing the pads will compress?

If u adjust that your handbrake will be well high. But, u see the teeth? there will be a little plate to hold it in place (the triangle thing), pull that back, and wind it in until the drum will go on. BUT... The handbrake will be high! and it'll only 'bite' the one side!!

I've managed to get it back on with with adjusting the strut in the drum, but as you say, the handbrake is slack as fuck. Tighten up the cable via the nut above the rear axel?

No, as you've adjusted it within the shoe, it'll need re-adjustment in there. You'll need to grind that lip off. Plus, if u use the adjuster above the axel, you'll tighten up the other side too, so then the wheel wont spin!

Whenever I've had trouble with drums a pair of flatblade screwdrivers to pry the shoes in at the bottom usually works fine.

Bloody hell fire.. Well, the handbrake still holds anyway. Not very well, but it holds and will have to do! Until MOT time and they bend me over about it. Might just have to buy some new drums. £43 on eBay, so not so bad.

That is not the handbrake adjuster

The middle bar should be adjusted so that the drum can fit over the shoes.

Then when you apply one click on the handbrake they should just slightly catch.

That isn't setting up the handbrake though, just how far from the drum they sit.

That is the handbrake adjuster Sean.

edit: I suppose it's not technically because the bit Steve is talking about above the rear beam is the handbrake ajduster. But I've used that wee ratchet before to take up slack with my handbrake and it's been fine.

Um, not THAT far.. I didn't wind the strut adjuster all the way in. I may have screwed it in abut 6 or 7 times. You can still see about a CM of thread.

But TBH, when I first removed the drum, it knocked out the spring (right red arrow) and the handbrake went all strangely slack anyway, before I even bothered touching the middle bar strut adjuster...

But nothing is out of place? So god knows what's made it go slack..

I could do, I tried filing it with small needle metal files, but it would of done a better job if I filed my finger nails. I'll look into getting a grinder.

Just so you guys know, just been to the shop, and it seems to have adjusted itself. The handbrake that is.

Pulled it up and it becomes tight after about 6 or 7 clicks.
