so what ws the outcome?
I design & develop brakes, for cars, for a living.
This...
Quite a few cars now need the rear calipers retracting with software
is NOT true.
There will be a procedure in the Owners Manual or Handbook that will put the rear calipers into a "Maintenance Mode"
When the calipers are set to this state the pistons can be wound back as normal. It also prevents the car/software on-board the car from actuating the rear calipers while you're working on them. That's a very good thing as you could crush/amputate your fingers otherwise.
Getting the calipers into "Maintenance Mode" usually involves IGN Key On/Off while holding down the Accelerator Pedal or similar.

Still waiting. They took the car away at 09:00. I rang 30 minutes ago and they said they were waiting for a part - maybe they broke something else. Seemed to think I'd get it back today...

That's dodgy-garage-speak for 'we haven't got round to it yet' as I'm sure you know.

If you know the procedure for VW then a lot of people would like to know. I had VCDS to do it, but I also realised I could remove the EPB motor, and wind the screw out by hand.

I too am intrigued by this - having watched my garage use VIDA/DICE on the Volvo and other similar tools to do it. I have done it by 'hot wiring' the motor to a small battery....

Sound like a pretty efficient setup. Take 6 hours to do 3/4 of a job and then have no idea how long it'll take to fit the remaining pad and/or have bust/lost something else.

Well. It's on its way back to me. The part they were waiting for was a caliper. He tried to suggest that a failed caliper was the cause of the missing pad, which is obvious bollocks, confirmed by the fact that they aren't charging me for it, and they are offering a biggish discount if I ever want any more work done. As if.

So the piston made contact with the disc and was damaged, I’d be wanting new discs on the rear and a full brake balance check.
Yeah, they fitted new discs and pads both sides, but...
The auto parking brake no longer works, doesn't apply when you turn the ignition off, doesn't release when you lift the clutch, and the pedal goes to the floor until you've pumped it a couple of times - needs a proper bleed. It's going back again.
Hopefully this operator/branch is far away from where I live.
been very careful with what they’ve said so as not to admit any liability
I think that ship has sailed.
Trouble is, do you trust them to assess and be honest about whether or not the caliper has been damaged?
EDIT: Seen the update now, I'd be getting the state of the brakes checked over and sorted at another garage and sending them the bill.
It’s going back again.
If it was my car I’d be watching as the repair was carried out and get in touch with the The Motor Ombudsman service and repair dept, the garage involved have little regard for mechanical safety and I wouldn’t trust them to inflate my tyres never mind working on brakes.
Time to name and shame.
I still recall the brake caliper detaching from a mate's 3 mile old SC Bronson. Because the bolts were not tightened. The spare brake at the other end of the bike was loose too 🙈

That's sounding like someone who didn't have the right computer using brute force to get them back. Quite possibly looking at new calipers now.
... I’d wager that fitter won’t do that again (one way or another). I bet if people here were honest plenty of us have made similar mistakes.
I imagine most people would acknowledge that mistakes are easily made. Which is why you'd expect any professional outfit to have a process in place to stop them reaching the customer.
This is something that would have been glaringly obvious with a 5 second check.
i wonder if the pad was left out as the person couldn't get the piston back bacause of the parking brake :(. But, if they have already replaced calipers and disks they are obviously fully into getting this repaired but I can't see how they could have let it out with having to pump the pedal to the floor - that's insane
On the XC60 can't see any way of putting the parking brake into maintenance mode from the user console. I'm only seeing that info for newer vehicles but it makes good sense. The only thing that is scary in this procedure is messing with that, the rest seems ok although i would probably need a big meaty socket wrench to release the nuts
I also realised I could remove the EPB motor, and wind the screw out by hand.
That's how I usually do it. I have had cheap replacement motors fail a couple of times now leaving me away from home with a stuck on handbrake so I always carry the tools with me to take the motor off.

And maybe the ABS modulator? I'm wondering if the correct tool also releases the valves in the modulator? I've never had a problem, but then I've the correct tools for the job.

When you wind it out by hand do you then just leave it fully wound out afterwards? That would make sense to me. I saw one vid where someone said to wind it in which seemed a little counterintuitive
edit: ah, i see that it winds out by turning clockwise so that does actually make sense

For me, it was the £180 VW ones that failed regularly and the £40 eBay knock offs that worked fine. It was very easy to see why by looking at them. The gears in the VW one pushed against the casing which was open at one end, and it quickly split which let water in. The knock off was closed at both ends and consequently much stronger.
When you wind it out by hand do you then just leave it fully wound out afterwards?
Yeah, I think so, it would then wind in for ages on first application to find its bite point. But it was a while ago, so don't take my word for it.

Theyre demonstrating that they really don't have a clue what they're doing. I wouldn't trust them to not cause any more damage now if they have another go at putting it right , I think you need a chat with the manager about how they don't seem to know what they're doing and how can you be confident that the car is safe, and fully functional.
If you don't get good answers from the manager to give you confidence that they're going to make it right, then it's time to take it to someone competent get it properly repaired, and then claim the cost of doing that from the garage. I hope you paid by credit card, so you can dispute the charge. You may also need to go through the small claims court to get the money for getting a competent garage involved back off them.

I would also take it somewhere else, Kwik Fit stripped a brake caliper bolt and used loctite to "repair" it on an Astra i had, I spoke to the area manager who agreed to foot the bill no question asked and also offered compensation, which i didn't take, covering the repair and his apology was enough for me.
Imagine making that sweeping generalisation about any other occupation or group of people? I can only hope that the commentator who made that snidey, sneering insult is a renowned genius. Despite the evidence to the contrary.
@blokeuptheroad having worked in the trade for over 20 years, I could tell you many tales of woe involving fast fit type places, and brake fitters. I'm sure there are plenty exceptions to that generalisation, but if you've ever dealt with a typical brake fitter, you'll soon realise most have got little clue as to how what they're working on actually works.
To give an example, a previous employer had a driver/workshop assistant. Nice guy, but if you talked to him, you'd soon realise that there wasn't really that much going on between the ears, and who could get lost within the industrial estate. It took us several months, but he could eventually manage changing most tyres without assistance.
He left us to go work for a fast fit chain, and last I heard, he was training to be their Suspension/Steering/Alignment specialist. We didn't even trust him to torque wheels, we only let him change the tyres, yet there was a company quite happily letting him do safety critical repairs with little training, and that is far from uncommon.
A fast fit place is the last place I'd consider taking any vehicle for any safety related work, however there are also plenty garages with supposedly fully trained techs who really don't manage much better. The motor trade is full of people being paid to do jobs, who have little idea of what they're actually doing.
A key question to ask, is why is the motor trade so resistant to technician licensing?
Very few people would pay somebody unlicensed to fix their boiler, or an unlicensed electrician to carry out electrical work, but most people are quite happy to have anybody fix their vehicle.
I'm not perfect, and have had some interesting f*$* up's over the years, but I generally know how/why I done something wrong, and addressed the problem.
However leaving a brake pad out is major issue, and if I'd done it, I would be sacked. There is no excuse for it, especially on a setup where the pad can't just fall out.
Key thing when doing any brake work, is prior to refitting the wheel, you give everything a visual check, which includes pads are in and fitted the correct way round, all bolts/pins are in place, and you have a mental run through to make sure you've tightened everything that should be tightened.
Different garages have different approaches. I worked beside a dealer tech, who had been ingrained to do a five point touch check before closing any bonnet. Screenwash cap, Coolant cap, oil filler cap, dipstick, and finish with a visual check to make sure you've not left anything obvious lying.
All things that should be done as you do the job, but that final 30 second check just gives you that mental run through to check you've done everything, as there might be something you didn't do earlier, due to various reasons.

I'm not questioning your experience but I would respectfully suggest the issue is more likely to be with poor training and supervision in fast fit outlets, rather than "brake fitters are generally a lower level of intelligence". A lot of people conflate education (or training) with intelligence and they are not the same thing.
I could have probably chosen better words, but having dealt with workers in these places, they really aren't employed for their intelligence, or even their ability to do a good job. They're generally employed as they won't get paid as well doing anything else, and only remain employed as long as they don't make any major f*** ups.
The training is rather special. I had a good chat with somebody who worked on a contract training for a national chain, and he hated dealing with them. The chain wanted their fitters to have some form of qualification, and by all accounts it was trying. His example was them arguing over what size of spanner/socket was needed for bolts, and some weren't even confident as to which direction to slacken bolts.
As for supervision, I have never seen any attempt at a quality check being done in any fast fit place. They will no doubt supposed to be done, but these places generally have public policies about the expected standard of repairs and guidelines for advising about any other work, but I'm sure we're all aware of the upselling that goes on.
There's also the easily clever enough to do a good job , but idgas attitude.
It's cold, dark and raining. I've been here for hours in the freezing cold. I can't feel my hands or feet. I hate that supervisor , he gets to sit in the warm and always has a coffee on the go.
He's now given me this bloody brake job to finish before home time. I've not done one of these before, my training was boring. like being back at school and that didn't go well. I'll have a go and see how I get on...
IDGAS isn't restricted to brake fitters.
I've probably met a higher percentage of tyre fitters that GAS, than I have vehicle techs.
Tyre fitters are however usually an interesting breed. They usually know and accept their limits, and are quite happy just to stick to tyres. It's a job that seems to attract those who just want a simple life, and if you don't mind working at the side of a road, can be very well paid.
it would then wind in for ages on first application to find its bite point.
That's my experience too. If you think about it, using software to open the calliper doesn't know if you are fitting new pads or doing something else so it will just wind back in until it gets to where it needs to be. I think I read somewhere that it senses the resistance in the motor circuit.
The training is rather special. I had a good chat with somebody who worked on a contract training for a national chain, and he hated dealing with them. The chain wanted their fitters to have some form of qualification, and by all accounts it was trying.
A friend was a 'sales' manager for a college that had an automotive training facility and was asked by a chain* if they could organise a brake technician qualification for them. No problem he says, we can organise a 5 day basic course for your staff. Pretty much told it had to be 2 days max or they'd look elsewhere.
* I don't think it was the big one.
