During the initial period (the first year after your braces come off) you will wear it 24/7 for several months. Later, your orthodontist will tell you that it's OK to wear it only at night -- every night. After another year goes by, you can wear it several nights per week.
The Torque Converter can go bad, and many people mistake an engine miss, torque converter shudder, or an engine vacuum leak for a converter going bad. An out of adjustment brake light switch can also cause the torque converter to no lock up sometimes.A sticking valve within the transmission is the usual cause of an erratic lock up that will mimic a bad converter.

Mis-torqued lug nuts, bent wheel, out-of-balanced tire are all causes of shakes when braking. Unless I missed it in your presentation and one of the most important tasks to prevent brake chatter or vibration would be to torque all the bolts including the wheel bolts. If the bolts holding the wheels to the hubs are not properly torqued they will cause vibration when you apply your brakes.
