All four of my wheels were removed at 2nd service and a guage was used to measure the pad thickness. I know because they sent me the video.
They must be the exception to the rule then !.
The service schedule sheet must call for this function, which is then included into the price of the service of course !.
I mean seriously, if the pads had more then 75% of their fiction pads remaining, which is very likely on an EV, why would you even need to remove ALL of the wheels, to get a more fairly accurate measurement of the fiction pad thickness ?.
If you where a high usage case, covering LOADS of miles and was heavy on he brakes, then yeah.
But for low / normal usage cases, removing all of the wheels on the second service is a bit OTT.
I know a certain manufacture had problems with cracks appearing in the alloy wheels of cetain models, then there is good reason to follow protocol and remove the wheels.
I assume they did a front to back wheel rotation at the same time, as they had bothered to remove ALL of the wheels !.
My previous car was a VW Golf PHEV which we owned for over four years.
It that time it received 4 services at the same main VW dealership.
On the 1st service, front brake pads where recorded at 95%.
At the second service it was reduced to 90% - but on the third service it jumped back up to 95%.
When I challenged this, I was told that without removing ALL of the wheels and removing ALL of the pads and then comparing them with new parts from stock, then it is totally unnecessary and is added to the cost for the customer.
And to honest, the customer just wants to know that their pads are within the safety requirements limits set out by the manufacture.
