Today I was able to fit a new exhaust system to the Atlas. I had made a temporary repair to the old (non-original) system but it was really beyond repair. Original systems are no longer available so I was lucky to follow a link to a company that had produced a replacement system.
The old system was soon removed and after a bit of a struggle the new one was installed.
After that I called it a day, so tomorrow I will clean them in the parts washer before leaving them in the ultrasonic bath for a few hours. One caliper had 3 layers of paint, black then white then red! Unbelievable. The paint stripper is useless on paint but it loves nitrile gloves!
