A burning rag held at the air intake was a favourite on big old diesels, a bucket of burning fuel to heat the fuel tank was often needed before the advent of winter diesel which stopped the fuel 'waxing'.
Another trick was to put some petrol in the tank, used to stop the diesel waxing. Not too much, or you would blow it up :)
 
Worth checking what the manufacturer says about changing pads. They may have a life expectancy in terms of time as well. So even if not worn out, if they are several years old it may be advisable to change them. Sometimes the backing plates can corrode, potentially causing the friction material to become detached. Certainly something that should be checked at each service.
The makers attaching time constraints on parts for servicing have always been a bone of contention with me. A friend took her motor in for inspection and service, the quote was north of £5,500 after inspection, so she walked away.
She showed me the quote, which included new disks and pads all round. I rang dealer a to check if they actually checked the disks and pads, as the car, a Porsche, had under 10,000 miles on it. When I asked what mileage they recorded on inspection, they didn't even know or have it recorded. They just said it's on the list to change at 5 year service. Yes it was a Porsche main agent before you ask.
I got them checked for her by an independent garage who specialise on Porsche, and they gave them the all clear. He just said was it the ********s dealer in North **********n, as that service manager would not let the mechanics inspect anything that was in the schedule.
His quote to me was
"... He's just graduate of something and came straight in as the service manager, the only nuts he has ever touched are probably his own or his bossess"

Sadly I was not surprised at his comments, having seen and experienced this type of service manager in other main dealer franchises.

This is the sort of rip off practices that the manufacturers legitimise by adding the phrase of 50,000 or 5 years on service schedules etc. IT SHOULD BE outlawed for everything with the exception of tyres, which do have an expiry date, but which are rarely pointed out on inspections as they only bother with tread depth and damage......

True, but I have a maintenance / service plan with BMW and they say its all good.

Aye, in the 80's I had one of the first VW Jetta Diesels in the country (non turbo), in the handbook VW specified 1 gallon of petrol to tankful of diesel when temps were below freezing.

I saw a picture of the brake pads of a Tesla Model 3 with I think 300,000 miles on the clock? The brake pads looked hardly worn. This is no doubt down to regenerative braking.

Yep. Musk reckons the pads can last the life of the car. Driving style is very different - you approach any turning or non emergency hazard and just lift off the accelerator. The car slows down in a measured but pretty quick way. You get used to just covering the brakes rather than using them. There is also almost zero disk wear.

With EVs the whole maintenance industry will be radically changed as there is very little do to. The cars are self diagnostic (or can be). Stupid stuff still goes wrong, like the heaters.

My point was they ought to be examined to ensure that they have not suffered any degredation due to age not just wear, exactly as your independent has done. The fact that the main dealer hasn't got a clue doesn't surprise me, most haven't.
The issue is that the friction material is glued to the backing plates that actually retain the pads in the caliper.
On an ICE vehicle the pads will typically wear out long before the glue is likely to be compromised.
Even so, anyone who does this for a living will have seen instances where the friction material has begun to separate from the backing plates, usually due to corrosion.
The pads on an EV wear much more slowly, so this is potentially more likely to become an issue. They should really be checked properly at every service, just the sort of thing that is often skimped by dealers.
Try marking your wheels in some way next time you take the car for a major service at a main dealer. I would bet in many cases they will not have taken them off. And if they haven't taken them off then they haven't checked your brakes properly.

That’s not the case, for example on our MG the pads can be easily seen through the wheels and from underneath. At 1 year old it’s highly unlikely to have detached from the backing so the accusation that they haven’t checked the brakes properly is absolutely unjust.

Easiest option is to put the locking wheel nut removal socket somewhere they wouldn’t necessarily expect to find it and if you don’t get a call asking where it is you know they haven’t bothered.. I did on one occasion take my car to a local tyre chain/fitters for a service and specifically mentioned a squeak from the brakes on a wheel I was concerned about, suffice to say the young lad who carried out the “service” was subsequently dismissed although not at my behest. They told me the brakes were fine even though they’d failed to remove the wheels as they broke the locking wheel nut tool but worse than that they also cracked the sump refitting the oil sump bolt and managed to leave a screwdriver under the bonnet. Not happy that the brake was still squealing I took it to a local small independent shop asking for a second opinion who raised the car up and called me back to the shop to see all the oil running out of the under engine cover. The brake that squealed actually had no pad left, just the backing plate! The bill from the small independent was paid by the tyre place which was for much more than they had originally charged me and was why the lad lost his job.
