While completely overhauling the rear brake assemblies for my 87' 924S I encountered a very frustrating problem with the emergency brake shoe retention springs, (928 352 957 02). It seems that no matter what position I place or rotate the hook end of the compression spring to, (once inserted through the brake shoe backing/retaining plate), it will not grab or hook on to anything and the spring slips out of the hole falling into the drum portion of the brake housing. The replacement springs all seem to be too weak to hold the shoes to the backing plate and the springs rattle around, again falling into the emergency brake hub. Has anyone else encountered this problem or have any suggestions/solutions?

Thanks for listening and any and all help.

Those things are a bitch to install. I usually use a flat blade screw driver to compress the spring, and then twist it 90° into its locking position. It can be tricky to get the hook into the vertical slot far enough that you can twist it around to grab. Make sure you're only turning 90°, and then inspect from the back side to ensure that the hook is firmly seated on the back side of the trailing arm.

You may not be hooking them onto the right spot. I recall them being extremely tight, and thus quite hard to install.

You'll need to look where you're putting them... they go on a raised "rib" cast next to the hole.

What Dan and Rasta said, but I was able to do it with a pair of needle nose pliers. It took several tries until I discovered the raised rib.

I can honestly say I tried all 360*(less due north and south), but no joy and I didn't feel a ridge. I'll give it another go and see if I can find the "rib" as soon as the weather breaks. Will let you know. Thank you all.

You need to put your head back there or you'll never get it.
