| Anyone got a VW service gadget nearby the Wirral? |
|
I promised my mate I’d change his front pads, and rear pads and discs on his MK7 Golf to help him out as he’s had to spend a lot of cash on it recently. Watched a couple of vids and it’s all the usual stuff until I saw one mention of an EPB on some models.. which it turns out his has 
It’s just an actuator on the back of the rear callipers but it has to be deactivated/put into service mode via a suitable tool before you can wind the rear callipers back. My basic OBD tool won’t do it. I can’t find any secret button combos to do it. It doesn’t seem that you can just leave the EPB ‘off’ either. Before I go spending cash on a tool for someone else’s car has anyone got a VW servicing gadget nearby that I could borrow to stick the EPB in service mode? D4 XS, gone, much loved, never forgotten

Dont forget the 7mm allen for the front discs either.

Front calipers.
I didn't have one so used an M50? on my VW Cali. Now have one in the toolbox.
Handbrake was wind back. VW parts are ouch. I used Brembo but as mine is big braked I had to order from AutoDoc

It is possible to remove the EPB actuators from the caliper & wind them back manually - there's a few you tube vids on that, but obviously better to do it properly with a service tool. My Autel (think its an MK808) does do it, but a bit too far away!
You may also need a 12 point spline drive to remove the caliper carriers I think. Check for this before you start... Not part of a normal socket set and difficult to find. And was extremely tight...
Rear caliper removal was a horrible job to do on the driveway.
Note - I'm assuming Mk7 Golf is similar brake system to 2015 Audi Q3, which was what I was working on, and found that all it's parts were actually VW Golf Long succession of Disco's since 2001...

As Dave T has said it should be possible to wind back the rear calipers manually.
My son and myself certainly did on his 2012 Tiguan having been told it was impossible.
A bit of a Google search soon provided 2 ways to do it.
Firstly by doing a bit more disassembly and winding back by hand.
Secondly by disconnecting the electrical supply and using a 12V supply to do it electrically.
I felt more comfortable with the Manual method so we did that.
The system on the car was so much better than on the D3/4, and so much easier to maintain, that I was a little annoyed whilst doing the job that a similar system couldn't have been used by LR. Heaven doesn't want me, and hell is afraid I'll take over.

Yes, to clarify, I wound the EPB actuators back the manual way. Easy enough, just requires care to avoid dirt getting into mechanism whilst 'split'. Long succession of Disco's since 2001...

Thanks chaps. I did a bit more searching based on your experiences and found the video where the guy simply applies 12v to the actuator, reversing polarity for in and out. I also found the (really shaky!) video of the guy splitting them in two.
If it were my car I think I'd try the 12v method for sure. I guess I'm just a bit wary that it's not my car. If one of them went 'pop' as I stick 12v onto it, it would be a massive ballache. Especially as he's coming from Leeds to stay with us over the weekend.
I can still do the fronts, these are pads only (discs were done with last pads and are fine) so I shouldn't need the spline bit to remove the caliper carriers, just the two spanners to get the calipers off. But thanks for the heads up 
I'm looking at Autel etc. now, to be fair it may be an excuse to upgrade my old OBD2 reader

**As Nasher says, I've also done a couple VWs and a VX manually winding the calipers back - watch the YouTube and its easy enough

Thanks again all for the advice
I've bottled taking his callipers apart or firing 12v into them, and now bought a Carista dongle which has 1 month free subscription, so I can do the job and then revisit it in future if needed as my wife's got a skoda so it will work with that too.
I've checked I've got a 7mm socket hex bit D4 XS, gone, much loved, never forgotten

James, check 1m 23s in this:
These caliper carrier bolts were an absolute pig for me. Easy with a pit or a lift, but not so easy on a driveway with axle stands. I had to go out and find the 14mm 12pt bit on a Saturday afternoon when all motor factors were closed. Just sayin' Long succession of Disco's since 2001...

Yikes not another special bit required.
You can log onto the VW tech page for a small fee and download the relevant sections for the front and rear brakes. It list the tool for mine as a T50036 (what it doesnt say is its 7mm)
I'll try and find the link.

I'm completely regretting offering to do this now
I've bought a set of stubby impact 12-point bits for the caliper carriers. I'm also planning on attacking them the night before with plenty of plusgas 
Fingers crossed D4 XS, gone, much loved, never forgotten

You're be okay. Has anyone mentioned stretch bolts (for the caliper arms) if you're doing the discs. (Not sure if the Golf is the same as the Transporter)
