What is the EBC Brake-in coating on the pads?

The Brake-in coating on the Ultimax2 pads helps to speed up the process of mating the new pads to the rotors. This means you get better braking performance sooner after installation, with less chance of uneven wear during the break-in period.

Are these rotors one-piece or two-piece?

The EBC RK series rotors included in this kit are solid, one-piece rotors. They are designed as a direct replacement for your vehicle's original equipment rotors.

Do I need to buy any other parts to install this kit?

This kit includes the rear brake pads and rotors. It is recommended to inspect your brake hardware, such as caliper bolts and brake clips, and replace them if they show signs of wear or corrosion. Always refer to your vehicle's service manual for complete installation procedures.
