In school i got the chance to connect to a truck with a lap top using quick serve to diagnose trouble codes. The the best way was to just disconnected sensors and to see if i can find the reason the light on the dash appears. This is pretty new to me i have spent about two hours just seeing whats there, trying to get comfortable with quick serve. What i learned so far is go to the reason first. Find out why that check engine light is on and fix that problem. Then go on to see if anything is else is wrong but first always go to the reason. Diagnostics using the laptop is defiantly something i want to get more into and possible to be hired to do. Here is a picture...
Also the other day a truck came in to get new steer axle brakes. But when i pulled the drum off it was all white and same with the inside of the rim. Well what happened is the rim was very old so it was wore out and only about half of the drums surface was flush with the rim. I could actually feel the inside of the rim it was like a ridge where the drum had worn in. So i talked to the driver and we agreed that the truck needed new drums and new rims as well. Here are some pictures to better explain.
