As part of the servicing I do myself I measure the brake pad thickness, now the method I use is highly susceptible to inaccurate reading, I use a tape measure and a small screwdriver to push it against the disc and measure to the pad backing. The front pads seem to have not changed at all over the last 45000 km, the pads have been on 160000km which I think probably should require replacement but 75% is just motorway cruising.

That apart is uneven wear on the front pads common? After previously having a Hyundai as my main car which are generally renowned for uneven wear and changing them every 30000km and around 50% wear mostly as I was in heavy stop start traffic, I'm just curious how come my pads have lasted so long.

Because you are mostly cruising on the motorway.

You can get a set of pad wear tools for literally £10 - no more inaccuracy.

It's probably time for some new brake pads. Even if they have plenty of meat on them, they have been exposed to temperature and braking cycles for 100k miles - the pad material will have degraded. That could be the cause of the uneven wear, along with calliper issues, disc issues or misalignment.

All that aside, a certain manufacturer isn't known for uneven pad wear. Poor quality braking components and defective parts maybe, but if the system is in perfect condition then there should be no uneven wear.
