IMPORTANT: Break In New Brake Pads/Rotors Using The Pad Bedding Procedure As Follows. Proper Pad Bedding Can Prevent Rotor Warping.

The break-in procedure is critical to brake performance. The reason for a proper break-in is to establish an even layer of friction material deposited on the rotors from the brake pads. It is very important that this initial layer of friction material is evenly distributed. PowerStop has different break-in procedures, so it is important to follow the one pertaining to your specific kit.

Break-In Procedure for Stock Replacement Brake Kits with Coated Rotors

Break-In Procedure:

Perform 30 deceleration from 30mph to 5mph with the 30 seconds in between each deceleration for cooling. Each vehicle has slight differences in how the pads will compress onto the rotor, requiring this to be done on an individual vehicle basis.

After this is complete, drive around for as long as possible without excessively heating the brakes and without coming to a complete stop (Try for about 5 minutes at moderate speed). This is the cooling stage. It allows the heated resin in the brake pads to cool and cure.

After the brakes have cooled to standard operating temperature, you may use the brakes normally.

This applies Z17 Evolution Brake Pads.

Break-In Procedure for Performance Upgrade Brake Kits With Drilled & Slotted Rotors

Break-In Procedure:

5 moderate to aggressive stops from 40 mph down to 10 mph in rapid succession without letting the brakes cool and do not come to a complete stop. If you’re forced to stop, either shift into neutral or give room in front so you can allow the vehicle to roll slightly while waiting for the light. The rotors will be very hot and holding down the brake pedal will allow the pad to create an imprint on the rotor. This is where the judder can originate from.

Then do 5 mod­erate stops from 35 mph to 5 mph in rapid succession without letting the brakes cool. You should expect to smell some resin as the brakes get hot.

After this is complete, drive around for as long as possible without excessively heating the brakes and without coming to a complete stop (Try for about 5 minutes at moderate speed). This is the cooling stage. It allows the heated resin in the brake pads to cool and cure.

After the brakes have cooled to standard operating temperature, you may use the brakes normally.

This applies to Z36 brake pads
