Diagnostic Steps

1
Inspect the brake pads for wear and thickness using a caliper gauge.
2
Check the brake rotors for scoring or uneven wear.
3
Examine the brake calipers for proper operation and any signs of sticking.
4
Inspect the brake hardware (shims, clips, and pins) for corrosion or damage.
5

Solution

1. Preparation

Gather tools and materials: brake cleaner, socket set, torque wrench, caliper tool, and safety glasses.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and glasses for protection.

2. Lift the Vehicle

Use a hydraulic jack to lift the rear of the vehicle.
Secure it with jack stands to prevent any accidents.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the rear wheel.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using the socket set.
- Slide the caliper off the rotor and secure it with a bungee cord to avoid putting stress on the brake line.
- Check the pads for thickness; if less than 3mm, replace them.
Replace Brake Pads:
- Remove the old pads from the caliper bracket.
- Clean the caliper bracket and apply brake grease to the back of the new pads.
- Install the new brake pads into the caliper bracket.

5. Inspect and Replace Rotors (if needed)

Check the surface of the rotors; if they are scored or below minimum thickness, replace them.
To replace, remove the rotor retaining screws if applicable and slide the rotor off the hub.
Install the new rotor and secure it with screws.

6. Reassemble Components

Reinstall the caliper over the new pads and secure it with the bolts.
Tighten the caliper bolts to the manufacturer's specified torque value (consult service manual for specifics).

7. Reinstall Wheel

Place the wheel back onto the hub, hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
