Yikes. I thought this was going to be a walk in the park but no. I am attempting to replace the front brake rotors on my 968 but I can't get the Grease cap/Dust cap off. The workshop manual says to use 2 tire irons to pry off. I am using a screwdriver and the nail remover part of a hammer. The thing won't budge. Please please i need advice quick. Also keep your answers "dumbed down" because i'm not very mechanicly inclined. (Had to look up tire iron)

 

Why would you want to take the grease cap off ? If you're only changing the rotors, take wheel off, unscrew the small screw that just holds the rotor in place, and tap gently (use rubber hammer if you have one) and the rotor should fall off. I just replaced mine today. Good luck

!!!!!!!!!!!!!!!!!!!!!!! Where exactly is this mircle screw?

 

There should be two small phillips head set screws holding the rotor hat to the hub. Unscrew those and the rotor will come off. You may need some gentle taps as Cervi describes.

 

You both rock!!! Thanks for your help.

 

Also, there are two M8 threads in the rotor and I always use a cheesehead to screw into the threads. You alternate between teh two threads. This forces the rotor away from the hub. Does the same thing, but there is no hammering involved.

as to the original question, since it is a good idea to repack the bearings while you are in there, to get the cap loose if it's really stuck, at the top where the cap meets the hub, squirt some tri-flow between cap and hub - use liberally - let it soak

then, get a good drift, set it on the lip of the cap, and tap the cap off, working your way around the diameter in a criss-cross pattern, a little at a time - be patient and work slowly around

 

To add to this, I would recommend a brass drift so you don't mar the aluminum hub..

 

yup - that's what i use - i should probably have clarified that when saying "good" - thanks
