Porsche 944 Front Brake Disc Installation

First take the front wheel off.

Remove the  brake pads:

1&2 Take the clips off the end of the retaining pins
3. Remove the spring then remove the retaining pins
4. Remove the spring plate from the back of the pads
You can now remove the pads from the caliper

Remove the Caliper:
Looking at the caliper from above you should see two large bolts (19mm)
The top one is marked in the photo, the bottom one is directly beneath

These bolts have more than likely had some thread lock applied, mine did.I had to apply a lot of heat to them before they would budge.
Once the caliper is removed, hang it from a piece of wire so there is no weight on the brake pipes.

Hub and Bearing removal:

Pry the hub cap off using a mallet and chisel (or large flat tipped screwdriver)
You will now be able to see the bearing collar. There is a hex bolt which need to be loosened in order to remove the collar and in turn the bearing and finally the disc.

Loosen the hex bolt but do not undo it all the way. Unscrew the collar and remove the wheel bearing and seal.

Remove the disc from the hub:

There are 5 bolts which hold the disc onto the hub.Undo these and split the hub from the disc.

 

Attach the new disc and bolt onto the hub

Reverse the instructions to reassemble.

Brake Discs

I will be changing the front discs this weekend, first part of some maintenance before the ring trip in April.

Oil Leak

During my weekly dipstick checks, I noticed that the oil level was slowly reducing.I checked underneath and found quite a bit of residue.It looks like a small leak which may have been happening for some time.I degreased as much as I could then pressure washed the bottom of the engine to clean it up for a better look.I think the leak is emanating from the crankshaft seal.The belts are due a re-tension so this job can be done at the same time as I believe the belts need removed to replace the front engine seals.

Update

The leak was indeed caused by the front engine seal.There was also some balance shaft seals on the way out so they were replaced as well.

Parts list:

999.113.281.40 - Oil seal : Balance

928.105.139.02 - Spacer sleeve

999.113.351.40 - Oil seal : Crank

999.707.283.40 - O ring

944 Oval Dash Instrument Cluster Lights

The instrument lights on the oval dash 944 are known for being dim.Mine were bad so I followed this guide to remove the cluster and check out the reflectors.
Cluster Removal
The reflectors looked like they had seen better days

                                     

I removed the silver reflective paint with nail varnish remover and replaced it with tin foil as per this guide

Instrument Lights
The bulbs in the cluster had a greasy/dusty film on them so I cleaned them as well.

The result is a much brighter instrument cluster and for an hours work, well worth doing
