I have just done the front and back pads on my 156 2.0 TS. I wish I had read this post first, I really had a good chuckle.
My front and back pads took two weeks - I had to order that piston re-wind tool, which took a week to get here to SA.
If you have the right tools, this is a morning's work. If not, many ales and lots of swearing.
The only issue I have now, is that the brakes go soft when I start the engine. So not sure what the heck is going on there.
Cheers for a great read.
