Proper way to bed in brake pads and rotors

I have seen many people suggest that to bed in brake pads you need to do a few hard braking stops from high speed. This is the worst way to treat new pads or rotors. The procedure below, though it is a pain in the but, is the best way to bed in new pads and/or rotors:


*While the vehicle is stationary, pump brakes to ensure a firm pedal.

*Drive the vehicle cautiously to test fit and function.

*The brakes should be smooth, with no vibrations, judder, etc.

*Drive the vehicle to a remote area and perform at least 30 brake applications of 3-second duration. Use light/medium deceleration with varying starting speeds. Leave at least 10 seconds between each brake application.
-The purpose of this procedure is to gradually increase the temperature in the components without inducing thermal shock, and to mate the brake pad and disc friction surfaces.

*After the repeated stops, drive the vehicle for a few miles with little or no braking in order to adequately cool the components.

*After the above process is completed, the system is ready for normal use.

Note:When the system achieves elevated brake temperatures for the first time, a slight increase in pedal travel and pedal effort may occur. After this first "fade" and proper cooling, the system will maintain its optimum performance at all temperatures.
