| Rear Brake Pad Replacement |
This is actually probably one of the easiest DIY servicings
you can do to your car. It is very simple and best of all, it is fast.
On top of that, you really don't need many tools you shouldn't already
have, and the one tool that you need (the reset tool) can be rented
from Autozone for a $35 deposit, which is returned when you bring
it back!
Note:
You will find that halfway through the how to, the calipers are all
of a sudden red, that is because we painted them at the same time
as replacing the pads.
This DIY is very specific to the MKIV VW. Although you can use this
how to as a guideline for other applications, you might have to change
certain steps or reorder them. |

| Step 1: Remove Lug Covers |
| The first
step to removing the wheels is removing the lug covers. Most vehicles,
if they have lug covers, have a tool that is provided to remove
them. Usually this is a simple "hook" or equivalent that
you can just pull them out with. If you have lost yours, you can
use either a hex key or a screwdriver to get them out.
To get them out, just put the hex key in the middle, leverage it
sideways, and pull towards you, they should pop right out! |
| Step 2: Removing Lug Nuts |
| Figure 2.1 |
 |
Most everyone should already know how to remove the wheel at
this point. Make sure your e-brake is on so that your wheel doesn't
turn while you are trying to get the lug nuts off. Get your lug
wrench, place the shorter end on the lug nut, and turn it counter-clockwise.
If the wheels are new, or the last person to put them back on
used an air impact drill, then they may be pretty tough to get
off. What you want to do is make sure the car is steady, set up
the lug wrench so that it is horizontal pointing left, brace yourself
with one hand on the car, and kick downwards. This extra force
should break the lug nuts loose.
Safety Note:
If you are kicking the lug wrench to loosen up the lug nuts,
it is recommended that you have the car on jackstands, and that
the car is fully secured. Make sure you have the car in gear so
that it doesn't roll away. A pair of bricks wedged into the front
tires also helps secure your vehicle.

| Step 3: Removing Your Wheel |
Depending
on how long it has been since the wheel was last off, if ever, this
might be fairly tough to do. If the wheel doesn't pull right off,
most likely it has been "bonded" with slight oxidation.
This is where the mallet comes in handy. Give the tire a tap with
the mallet on every side of the wheel, Wherever there is a spoke
is a good guideline. This should loosen up the wheel a little bit.
If the wheel still doesn't come off, squat in front of the wheel,
place one hand on the tire facing you, one hand behind the tire
on the opposite end. Push and pull, then reverse your hand position,
so that the hand that was behind the tire, is now in front and vice
versa. Keep this up, all around the tire until it comes off. |

This is actually a lot less daunting then it looks at first,
especially if you haven't done it before. Before you start though,
again, make sure your e-brake is disengaged.
I recommend the kits that you can rent at Autozone, best
of all, they are free, you just place a $35 deposit with them,
and when you return it, you get your money back. The part number
for the unit is #OEM 27111.
To put the tool together, place the flat panel with a hole in
the middle over the end of the tool. You then need to find the
piece that fits piston, if you have an MKIV VW, most likely the
unit you use is the one in the top middle, as shown in the picture.
You then have to place the tool within the caliper. Turn the tool
so it is small enough to place within the caliper, than turn clockwise
to expand the tool and compress the piston. The sheathing for
the piston should be flush with the piston at all times. Compress
the piston until it is reset or you have enough room to fit the
new pads.
Note:
The technique of using a clamp, and a block of wood to reset
the piston will not work because the piston needs to be turned
while compressing it. The kit makes it so much easier that there
is no reason not to get it, especially since it is free.

| Step 8: Replace Caliper |

| Figure 8.2 |

You are near done, all you have to do now is place the caliper
back, it should be a lot easier to place it back then take it
off because the piston has been reset. Match the bolts and holes
up, and replace the screws, then tighten up and secure the caliper.
|
| Step 9: Replace Wheel |
Go ahead and replace your wheel,
have a friend help since it is easier to line up the holes that
way. Tighten the lug nuts until they are snug, but don't tighten
them fully yet. Let down the vehicle off of the jackstands or jack
and once the vehicle is on the ground, tighten the fully. Once you
have them tight, stand up and using leverage, give it another 1/8
of a turn or so for good measure. Your tires are back on! |
