Hi All,

I have read a previous post on this topic but I would appreciate some clarity on it.

I need to get at the rear brake shoes on my S2 coupe, now as I understand it there are two castle type ring nuts that have to be removed. What I understood from the previous post was that the outer nut (large outer red circle in the pic) doesn't have to be removed but rather the inner one, the inner nut being locked at 320nm?

Also, to remove the large outer nut it is best to drill where I have marked "O" in the pic and then with a drive of sorts and a hammer, undo it?

If there is no tool available, how else could the disc-cum-drum be removed?

I just need to check the brake, the bearing sounds and feels fine.

I also think I must be missing something as I can't locate the shoe adjuster, I have looked through the aperture where it is supposed to be located but can't see it.

Thanks!

Right. You take off the inner (axle) nut to remove the hub. I use a large impact puller attached to the holes for the four wheel bolts using hex M14x1,5 bolts to remove the hub from the axle. You do need the special tool to remove the nut.

Just to service the handbrake shoes you do not need to remove the large outer ring. That is only necessary to replace the bearing. It might be wise to remove the bearing if you are having the discs and/or drums skimmed. If you want to remove the bearing without risk of destroying it, you must make a tool that clamps the two inner races together while pressing the bearing out. To press the bearing back in I use the outer race of an old bearing with a few tenths of a mm turned off from the outer diameter.

To remove the outer ring I do indeed drill a small hole where you drew the O and use a drive and a 2 kg hammer. If you try to do this on the car the rear spring will dissipate the impacts of the hammer. Best take the hub off first and place it on a concrete floor against the wall. Note there is a locking spring in a groove on the inside of the ring. This has to be taken out first. If you have the time, use some penetrating oil and let that soak overnight.

When you put the hub back on, make sure you apply the pushing force to the inner race of the bearing!!! Do not push against hub or disc.

The see the shoe adjuster wheel turn the hub till one of the peek holes is at the bottom. Lie on the floor and use a narrow beam light. Look slightly up. The wheel is chrome plated. If it is not completely dust covered you should see it. You may have to vary the position of the peek hole slightly.

I don't see how you can remove the inner nut without the proper tool. Same for the outer ring, but you may not have to remove that one.

Thanks Huib, that's brilliant! I was wondering however if it would be possible to take some steel tube of the correct size/diameter and cut out the 3 "keys" and use that...
