1994 POS Jetta Rear disk removal

[Me]

Since this model seems to need new rotors each time you replace the
rear brakes, I decided to try it myself.

I've done many front brake jobs but never a rear disk.

It appears that there are two 8 MM bolts, (allen wrench type of
course, damn VW) holding on the caliper slides.

Is this correct?

Are they 8 MM and are these needed to remove the rotor.

BTW, if I ever think of buying another VW, please shoot me.

This is after owning 7 of them, all diesels prior to this.

Thanks

Hmmm
I think resetting the rear caliper pistons is harder than replacing the rear
discs. It should be easier with that special tool. :-)
If your discs are fine reuse them!
I believe you are correct on the size of the bolts.
JMHO

Replacing the rear rotor involves more than taking off the brake caliper
and pads, the rotor is part of the rear hub assembly, you will also need
to replace inner and outer wheel bearings when you get the new rotor
assembly, plus the grease seals. There is a trick to adjusting the rear
wheel bearings, so they aren't too loose nor too tight. Also, you will
need a special tool to "wind" in the piston on the rear caliper (if you
replace the pads, since the new pads will be thicker) for the rear parking
brake. I think the tool looks like it has 2 "pins" that plug into the same
pattern on the piston.

These cars are pretty easy to replace the rear rotors on, I just did
the rears on my 94 Corrado. I bought 2 rear rotors, pads, the 8 mm
allen-bolts that hold the pad carriers to the rear spindles and two
rear wheel bearing kits. This is how I remember doing it.

- Remove parking brake cable, pull in lever on caliper and pop off
cable. There should be enough slack to do this without un-adjusting
the p-brake.
- Remove the 2 - 13 mm bolts that hold the calipers to the pad
carriers. Take the calipers and sit them on the axle beam towards the
front of the car. Don't let them hang or kink the brake line.
- Now you need to remove the 2 - 8 mm bolts that hold the pad carrier
to the spindle. These are easy to damage so be careful with them.
- Remove grease cap and remove rear rotor. Check the thickness of the
rear rotors & decide if they need to be turned or replaced. The rear
rotors are 10 mm thick new and minimum thickness is 8mm in the Bentley
for the Corrado.
- I don't have a tool to turn in the rear caliper pistons so I
improvised. If you can find a tool then I would use that. The piston
must be turned clockwise while having downwards pressure put on it to
get it to sit in the caliper again. I used a bit of silicone lube on
the piston boot to stop it from trying to turn with the piston. I took
an adjustable pair of pliers on put some tape on the teeth. I then
took that pair of pliers and adjusted it to fit on the ring that the
proper tool is supposed to sit on. I used a socket that sat on the top
of the piston and I just put downwards pressure on the socket with a
lever as I turned the piston clockwise. This works perfect for me and
I've done this many times but I've also heard people have used a
c-clamp to get the same results.
- Now you are ready to re-assemble the brakes and your done. Make sure
to adjust the parking brakes if needed and hit the brakes a bunch of
times before you drive it.

Hope this helps, Dennis
