Even as a technician there are certain things that I would rather have my buddy do who's also a technician then myself. I trust his work and there's certain things I just don't want to mess around with unless I'm getting paid
as a technician I have stubby flex head ratchet wrenches. Regular length fixed ratchet wrenches. I also have regular length flex ratchet wrenches and super long double box and flex ratchet wrenches with the offset. I use them all constantly depending on what I'm doing
While I am not a tire tech more of a general service and heavy line tech I do do tires as well. With that said I am sure there are other tires out there that I just don't see enough of to really know
Yes on diff service. As far as brake disassemble and clean/lube any technician that knows anything can physically check brakes and condition without total disassemble. I would offer the brake items as complimentary service no charge
