Hi
I have the same work done the last days but my motive was to do the check because of that the break is not coming lose totally.
They Always breaking a little bit.
My opinion is that the hydraulic cylinder is not working smooth and the automatic adjuster is also not working how it should.
My decision is now to change for disc brakes. The car has with 8000 km the hydraulic cylinder that bad that i have to change them and now with the new ones at 20.000 km the same.
The brake shoes looking like the same as yours. The shoes looking at some spots like new and at other spots they are at the wear limit. That could not be normal.
