Diagnostic Steps

1
Inspect brake pads for wear: Remove the wheel and visually check the thickness of the brake pads.
2
Check brake rotor condition: Look for scoring, rust, or warping on the rotors.
3
Examine brake calipers: Ensure calipers are functioning properly and not sticking.
4
Inspect brake hardware: Check for missing or damaged shims, clips, or anti-rattle springs.
5
Check for moisture or debris: Look for any contaminants that may be affecting brake performance.
6
Scan for error codes: Use an OBD-II scanner to check for any related error codes.

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench, OBD-II scanner.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to avoid any electrical issues during repairs.

2. Remove Wheel

Loosen the lug nuts slightly before lifting the vehicle.
Use the jack to raise the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the brake rotor; support it with a bungee cord to avoid strain on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the brake pads for wear; if the thickness is less than 3mm, replace them.
5. Apply brake grease to the back of the new pads and install them into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check rotor thickness with a micrometer; if below minimum specification, replace the rotor.
2. Remove the caliper bracket bolts and take off the bracket.
3. Slide the rotor off the hub; if it's stuck, gently tap it with a rubber mallet.
4. Clean the hub surface and install the new rotor, ensuring it is seated properly.

5. Reassemble Braking System

Sub-steps:
1. Reattach the caliper bracket and torque the bolts to the manufacturer's specifications (usually around 25-30 Nm).
2. Reinstall the caliper over the new pads and secure it with the caliper bolts.
3. Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Finalize

Lower the vehicle and remove the jack stands.
Tighten the lug nuts to the specified torque (usually around 100 Nm).
Reconnect the battery.
