How to Replace Rear Disc Brakes in a Hyundai Sonata

The Hyundai Sonata has one of two types of brakes in the rear of the car; the brakes are either disc or drum brakes. While they both offer efficient stopping power, rear disc brakes are easier to replace. Follow these steps to learn how.

Difficulty: Easy

Instructions

Things You'll Need:

• Car jack
• Torque wrench
• Mechanical wire
• 2 rear disc brake pads
• 2 pad retainers
• C-clamp

1. Raise the rear of the vehicle off the ground using a car jack. Support the vehicle on all sides with jack stands to prevent it from tipping.

2. Remove the rear wheels from the Sonata. Loosen the lug nuts with a torque wrench and slide off the wheels. Set them on the ground, face up, to prevent damage.

3. Disconnect the lower caliper mounting bolt. Rotate the caliper upwards and fasten it to the frame with mechanical wire.

4. Take out the pads from the caliper support. Remove the pad retainers as well if they require replacement.

5. Install the new pad retainers if they required replacement. Slide the new brake pads onto the pad retainers.

6. Compress the piston with a C-clamp. Remove the caliper from the mechanic's wire and rotate it downwards onto the brake pads. Replace the mounting bolt and torque it between 16 to 24 ft. lb. Remove the C-clamp.

7. Replace the wheel assemblies on the Sonata and lower it to the ground. Pump the brake pedal in a slow but firm manner to seat the brake pads.

Tips & Warnings

• Don't hang the caliper from the brake hose as it will damage it.
