Answer 2

probably one of the best source's would be the training material available through a BOSCH training clinic.. periodically local parts stores will sponsor a clinic [generally these are open only to the independent shops in the area of said parts store] however if a clinic comes up, and you are tight with the local parts jobber, he may invite you but be aware that fee's may apply . BOSCH clinics and trainer's deserve an A++ rating
Bendix clinics deserve an A rating but some trainer's only deserve a B
all will tend to push their own brand, weather tools or parts, however the best part is the books and diagrams etc that you will take home.along with the knowlege the trainer has given you.
