Emergency brakes were originally used to stop a vehicle during a failure of the regular brakes. However, emergency brakes are now used primarily to keep the vehicle from moving while parked because the regular brakes on a Hyundai Sonata rarely fail. Emergency brakes most often need to be replaced as a result of disuse, which can cause the components to rust and seize.
Tools Used: Tools, Parking brake shoes, Socket wrench set

Determine which type of emergency brakes your Hyundai Sonata will need. Emergency brakes typically function by activating the regular braking system on the driving wheels. The emergency brakes for the Hyundai Sonata use the drum brakes on the rear wheels.
Raise the vehicle and remove the rear wheels with a socket wrench. Pull the brake drum off the rear axle.
