Edcamp is a form of unconference designed specifically for teachers and their needs. What makes EdCamp an unconference? Unlike traditional conferences which have schedules set months in advance by the people running the conference, Edcamp has an agenda thatâs created by the participants at the start of the event. Instead of one person standing in front of the room talking for an hour, people are encouraged to have discussions and hands-on sessions.
Brake pads should be replace â¦ d every 30-40,000 miles depending on driving habits. When you change the break pads, have the rotors resurfaced at the same time. It only costs about $10.00 each to have them turned at the auto parts shop. Few professionals, if any, will replace pads without turning the rotors.
How to Replace Brake Rotors. Brake rotors are metal discs that are attached to the axles of a vehicle. When the driver pushes the brake pedal, the brake pads press on the rotor, creating friction, which forces the wheels to turn slower. That friction also causes the disc to wear out, and to need resurfacing (turned). But, the brake rotors may need to be replaced due to damage or excessive wear below a specified limit, how soon depending on miles driven and driving conditions (heat, dirt, sand, rocks, road salt, etc.).
