Early 924 Drum Brake Adjustment

Disclaimer: any information provided here is used at your own risk. I accept no responsibility for any damage you may do to yourself, others or you car. Having said that I thoroughly recommend getting yourself the Haynes owners workshop manual for the 924. It's the best publication of it's type for the car, oh and also make sure you're on friendly terms with your local porsche parts interpreter and wrecker, they can save you both time and money with their useful information.

Adjusting early drum brakes
If you have an early (pre mid 77) 924 you may have non self-adjusting drum brakes. They need periodic adjusting (when the hand brake doesn't work so well or you can feel the brakes fading a little)
1) Park the car on a level, flat hardstand
2) block the front wheels securely
3) place the car in neutral and release the hand brake
4) using a large trolley jack raise one rear wheel
5) for safety you can raise the entire back end and place on chassis stands
6) on the backing plate are a number of holes (covered by rubber seals) remove the seals. the inner two hide the adjusters (one for each shoe) and outer two are inspection holes so you can check the wear.
7) using a long flat screwdriver turn the adjusting wheel until the road wheel no longer turns freely by hand, then back the adjuster off a little until the road wheel turns freely by hand.
8) repeat this for the other adjuster
9) replace the rubber caps and repeat for the other side.
