V70: Wheels/Brakes Guide to rear pad replacement with EPB

[Sanzomat]

Here is a simple guide to replacing the rear pads on a >07 V70 with electric parking brake. This is based on solely my own experience having just done it but I take no responsibility for the contents!
I used an Autel MaxiEST EST201 with V1.08 software for the release and reactivation of the EPB.

Start by chocking the front wheels and jacking up the rear and making sure the car is properly supported. Remove the rear road wheels.

Plug the EST201 into the diagnostic socket (located just below the handbrake switch) and turn on the ignition (no pedals so you don't start the engine)

The EST 201 screen then looks like this:


You then select Volvo from the list of manufacturers (item 4):


If you want to you can check for any stored codes etc and you can also read the car's software versions. The next step is to scroll down to advanced:


Selecting advanced brings up the service menu:


From here you can have fun activating and deactivating the parking brake without using the normal switch but to carry in with the job select "Activate Service" When you select this you will hear the parking brake unwinding, just like when you normally release it but for longer. You can then get on with the dirty end.



Undo the bolts that hold the piston carrier. This needs a 13mm spanner and also a 15mm open ender to hold the inner part still. Once removed the piston and carrier can swing clear to expose the pads.


The old pads are held in place by the clips so don't fall out, simply wiggle them a bit and they come free of the clips:


Put the new pads into the clips in the reverse of taking the old ones out:


Here is a comparison of old and new pads. This is the worst of the old pads after 60k miles of use. The offside had about 2mm left, the near side had about 3.5mm.


The next step is to push the piston back in. I thought at first it would be one of those you have to rotate but in fact it simply pushes (I used a bit of timber batten and a tyre lever)
Then position the piston carrier back in place and bolt it on using the new bolts. The new bolts are supplied with the pads and come pre-coated with some thread locking agent:


Once both sides have been replaced and bolted up you go back to the EST201 and scroll up to Installation Check. This runs through a series of application and releases of the parking brake to make sure it all works. When you first go into service mode it stores an error code which gets cleared at this stage if everything is in order.


Assuming there are no error messages all you have to do is put the wheels back on and jack it back down again and remove the EST201 from the port and the job is done.

Here is what you get in the kit:


That should be the last time I'll have to do that on this car so if anyone wants to buy my EST201 please PM me. Its only been used once and I confirm it works a treat and is very easy to use. It comes boxed with a neat little carry case, a USB cable for downloading updates in the future, a disc of the software including an updating utility (but it is currently loaded with the latest) It currently has software for Mercedes, Audi VW, Volvo and Ford and it is rumoured that future updates will add other cars too.

Hope this helps someone. Maybe the admin guys could sticky it?

Hello mate

All you have to do is install the software it comes with and connect the EST201 to your PC/laptop. Then you browse to the Auteltech.com website. On the top right hand corner click on "United States" and change to "Europe-English"

Once selected it will bring you to the Autel home page. Again on the top right hand menu select "Support & Updates" Then click on ""Previous Generation Products" on the 2nd row, 1st item on the left is "EST201 Update Pack" - Click on that and save the Winrar file to your PC. Then locate the Winrar file and extract the 2 files that are contained in it by double clicking on the Winrar file.

Then you have your Software open select "EPB Service Tools" - locate the files you have just extracted and click on update. You need to do that for all of the menu items. Once done scroll down on the EST201 and you will see Volvo is now included.

Hope this helps

Yesterday I changed discs, pads and a wheel bearing on my V70 2008 (3).

I managed to rewind the two pistons simply by unplugging the electrical motor and connecting the two poles with a separate 12v car battery. You will see that the piston start rotating when the spindle has reached the end. Afterwards you can press the piston back as usual.

When activating the handbrake afterwards you can hear that the two motors run som extra time to reach the pads again.

There is no need for the special tool :-)

I can now confirm this as well. I used the 12V battery pack from my impact driver and connected it directly to the two terminals on the EPB (after having unplugged the EPB, of course). The first time I attempted it I had it backwards so it actually put the EPB on. I then was unable to take it off without turning the car back on and turning them off normally. Once I did this I was able to go back and reverse the poles of my two connections and the EPRB rewound without issue. You'll know you have it right when you hear the brake rewind for an extended period of time...say 5sec. As Peter indicated (above) no need for a special tool here nor is there a need to take the EPB apart. This is good news given the recommendation by VIDA to replace the seals on the EPB each time you open it up!
