I use a crowbar-like tool to pop off the bearing caps.

you can undo the caliper and leave it connected to the whole van.
Hang it, or place it on something, like a tall block of wood, so the caliper
is not hanging by the hose.
No need to open the hydraulics.

then the  disc and hub will come off the spindle.
Should really change the brake fluid to the front brakes too as part of the
job,
but get your pads and discs handled first of course.

I always put 'disc brake quiet' o the backs of the brake pads too.
make sure the pistons of the calipers are not stuck....they tend to do that
on old calipers.

Subject: Replacing Front 84 Brake Discs

Hi all,

I am just starting to replace the front discs, pads and bearings.  I am
wondering what is the best way to get the hub cover off?  I do not have the
special VW tools listed within the bentley and was looking for some
suggestions.  Also,  I am wondering if I will have to disconnect the caliper
from the line to be able to remove the Brake Disc?  It seems that there
would not be enough room with that little metal line to the caliper.  Anyone
in Bozeman, MT able to swing by and help a beginner mechanic LOL.
