Not sure if this is yet another seemingly small job that will turn into a whopper, but I am fitting new parking brake shoes and springs to my '85 S2 as everything was worn out/rusted/broken so much so that it pretty much fell apart when I took the disc off. So far so good but not so easy to put new stuff back on I find. New shoes and springs match the old ones but it doesn't seem possible to attach the springs at either end of the shoe without pulling the hub....please no or am I missing something?

Only use Porsche genuine spring all the one that are on Flebay are a pain you have to cut them as they are slightly to long as for shoes make sure that they fit in the adjusters some times they are to thick to fit. Screw dirver with a slot cut in it to fit springs .
That process has worked for me on a couple of occasions. It helps to tilt one of the shoes a bit while installing the second spring, then push it back into place.
In one of my big red rolling cabinets filled with tools, there's a kit of old-school tools from back when drum brakes were the norm. One is a handle with a hook through it radially, thin hook about 4" long. Grab the end of the spring with it, pull, engage target hole with spring, release.
For the 928 parking brake shoes, I assemble the cams, then the shoes with the cam end spring in place. Install the hold-down springs. Then the adjuster, fully retracted. Then the adjuster-end spring.
A nut-driver that fits over the end of the hold-down springs is perfect, as it keeps the hook concentric to the coil in the spring, and allows it all to rotate to engage the hook behind the backing plate. A spot of grease on the backing plate where the shoes ride is good. A similar film of grease on the threads of the adjuster will help it in the long run.
If you do it enough these are very useful...
Spring pliers - hook for spring end on one jaw, and round fitting for the coil spring holding shoe to back plate on the handle. http://www.sears.com/ctt-tools-inc-1...1&blockType=G1
Finally fitted the near side shoes springs having done the offside a couple of weeks ago.
- One thing I would add is yes start with the long spring (on the actuator/cable side). Key is to get the spring inboard of the actuator i.e. hub side so the shoes can be levered onto the actuator slots.
- Once this spring is on the right side of the adjuster I found the easiest way to to fit the shoes was to hold the adjuster end of the shoe in place and lever the shoe against the hub thereby extending the spring to allow seating.
- Once the actuator end is in place fit the adjuster end. I used a very small screwdriver through the hook of the spring and into the hole in the shoe, then levered the screwdriver to extend the spring and pushed the spring down the screwdriver and thence into the hole.
- Then fit the compression/retaining springs in the centre as per the tips in the thread above.
