The fluid level should be to within 1/4 inch from the top of the container. Place the cap onto the master cylinder and close the hood. Pressing the brake pedal after replacing the brakes forces brake fluid into the new caliper.
How are the rotors and brake pads changed?
The brake pads are the most often changed parts of the system. The rotors require less frequent repair or replacement, but they are relatively easy to remove and replace. The caliper is connected directly to the brake line. The brake line feeds brake fluid to the caliper, causing the brake pads to make contact with the rotors during braking.
How do you change the rotor on a Kia?
Place the new rotor into the wheel bolts, with the raised “top hat” section facing outward. Place the new caliper onto the new rotor. Tighten the caliper bolts with the Torx socket and ratchet.
