The reason for a proper break in is to establish an even layer of friction material deposited on the rotors from the brake.
Proper way to break in ceramic brake pads.
The gray film is material from the pads transferring onto the rotor face and the blue tint indicates that the rotor has reached the proper break in temperature.
It is critical to follow cool down procedures to avoid damaging nao ceramic and semi met friction material as well as the rotor drum.
Once those brake pads and rotors are mounted it is essential to properly break them in.
Following the proper break in procedure for new brake pads rotors using the pad bedding procedure as follows.
Bedding in commonly known as breaking in new brake pads and rotors is necessary for new brakes to work properly.
Known by some as the bedding in process breaking in the pads should be done any time new ceramic brake pads are installed or when purchasing a new car.
This may leave a light gray coating on the rotors which is normal.
Proper pad bedding can prevent rotor warping.
Some brake pads come with a special surface transfer coating that rubs off the pads and bonds to the rotors as the pads break in.
Breaking in new ceramic brake pads is an important procedure that is needed to maximize their performance according to experts.
Allow at least 30 seconds between brake applications for the brake pads or shoes to cool down.
The process works to put a layer of material onto the friction surface of the rotor from the brake pad.
These are good signs that you have bedded your brakes properly.
One thing to avoid with new pads is hard panic stops or high speed braking until the pads have fully seated.
