For this video we're
going to show you how to replace the rear brake shoes and the brake hardware.
We start the rear brake
shoe replacement, with the hub cap off you should see the axle nut which should
have a cotter pin in place which needs to be removed. Once it is removed we can
loosen the rear axle nut. After the axle nut is loose, we loosen the lug bolts
and then we can jack up the rear of the car. Make sure to support the rear of
the car with jack stands and then we can remove the rear wheel.
With the parking brake
off remove the brake drum. With the rear brake drum removed it's a good time to
take a picture with a digital camera. So if you aren't familiar with the
orientation of the brake components, you have a good reference for the
reassembly. It's also a good idea to clean the brake surface with a can of
brake cleaner, provided that you have a drain pan that you can place underneath
so you don't get your driveway or garage floor dirty.
To remove the brake
shoes, twist the brake shoe retaining spring pins with a pair of players while
holding the caps. Remove the springs and pins from both sides and save all the
hardware until after brakes are reassembled. Remove the lower break tension
spring, using a pair of pliers to grasp it at one end. Remove the upper tension
spring from the front brake shoe.
At this point both brake
shoes can be pulled away from the backing plate as a group, so that you can
unhook the parking brake cable from the parking brake lever. With the brake assembly
completely removed from the backing plate. Remove the parking brake push bar,
the retaining clip, and then disconnect the upper tension spring from the rear
brake shoe. With a flat head screw driver or a pair of needle nose pliers twist
open the parking brake pin clip. Slide the clip off the pin and pull the pin
from the brake shoe and the parking brake lever again save all the hardware
until you're done.
With the dis-assembly of
the brake shoes complete. Clean all the hardware, pins, springs, and clips to
make sure they're ready to go for the reassembly. For the reassembly we're going
to first start by attaching the parking brake lever to the rear brake shoe. With
the pin and clip use a pair of pliers to squeeze the clip in place to hold it
to the pin.
Smear a small amount of
grease on the backing plate on a break shoe nubs. Screw the brake adjusters in
completely making sure to align the slots and the screws vertically. Slide the
brake shoe retaining pins through the back of the backing plate for the front
and the rear shoes. For the rear brake shoe attach the parking brake cable to
the parking brake lever. Then line up the brake shoe with the wheel cylinder at
the top and the brake adjuster at the bottom.
Guide the brake shoe
retaining pin through the brake shoe. Set the spring over the shoe and then
slide the cap in place over the spring and pin. The cap needs to be pressed
down over the pin to compress the spring and then twisted 90 degrees to hold
everything in place. This can oftentimes be done with your fingers if not; you
can use a pair of needle nose pliers to twist the pin while holding the cap
down. Install the front brake shoe with the pin, spring, and cap using the same
Next, install the
parking brake push bar in place between the brake shoes by pulling the rear brake
shoe away from the rear wheel cylinder slightly. The push bar has a small notch
on one side. The smaller notch is going to be going towards the front and the
larger notch is going to go towards the rear.
Install the upper break
tension spring, which is the shorter of the two tension springs. By placing it
in the hole in one shoe and stretching it to the other hole with a pair of
pliers. The push bar has a small recess on one side so installing it on the
right side it would seem as it is upside down. VW decided for some reason to
use the same bar for left and right. On the right side which we are showing
here the recessed area is going to face down.
Next slide the parking
brake tension spring to the push bar clip in place over the bottom of the push
bar first and then over the tension spring. Lastly install the lower brake
tension spring placing it in place on the rear and stretching it to the front
hole with a pair of pliers.
Now double check the
alignment of the brake shoe with the brake adjusting screw. The brake adjusting
screw has a slanted surface. It's narrower at the top typically and wider at
the bottom. Make sure that the angle on the screw matches the angle of the
shoe. Rotate the screw around 90 degrees if necessary to get them to line up. Now
we can slide the brake drum in place and adjust the brake shoes. To show you what's
happening then we turn the shoe adjusters we have the front drum off here. We
use a flat head screwdriver to adjust the brake shoe adjusting nuts.
We access the nuts
through the holes in the backing plate. When you turn the adjusting nut the screw
move either in or out to push the brake shoe up or let it pull down to loosen
or tighten the brake. With the rear brake drum set in place we go underneath
the car the backside of the backing plate where we first adjust the rear shoe.
You want to rotate the
screw for each shoe until you can no longer spin the brake drum then back it
off a few turns so the brake drum spins yet you still feel some drag from the
shoe. We repeat the process for the front shoe. With the brake shoes adjusted
we install the brake adjustment and inspection hole plugs and place on the back
of the backing plate. Now coming to the front of drum with the shoes adjusted
you can hear the drag or resistance from the brake shoes as we spin the drum.
Now install the axle
nut, the wheel, and the lug bolts jack up the car, remove the jack stands and
lower the car back down on the ground. Torque the lug bolt and then finish up
by tightening the rear axle nut. The axle nut needs to be tightened to at least
250 foot pounds. You don't necessarily need a torque wrench you can do a little
quick math. If you weigh 150 pounds and you step out 18 inches away from the
axle you are well past 250 foot pounds. You want to tighten the axle nut until
the grooves in the castle nut line up with the holes
from the axle so we can install the cotter pin.
Once the axle is tight
we've installed the cotter pin we bend over to keep the axle nut from backing
off snap your hub cap back on and repeat the process for the opposite side
brake. The rear brake shoes have been replaced.
