Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a socket set.

3. Inspect and Replace Brake Pads

Remove the brake caliper bolts using a socket wrench.
- Tools Required: Socket set, torque wrench
Carefully slide the caliper off the rotor and support it using a bungee cord or rope (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any signs of wear or damage. If necessary, rebuild or replace the caliper.
Install new brake pads, ensuring they are correctly positioned in the caliper bracket.

4. Check and Replace Brake Rotors (if necessary)

Measure rotor thickness using a micrometer; replace if below the manufacturer's specifications.
Check the rotor surface for scoring or warping. Replace if damaged.
Install new rotors as needed, ensuring they are clean and free of grease.
- Tools Required: Brake cleaner, micrometer

5. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Torque caliper bolts to manufacturer specifications (typically around 25-35 Nm).
Reinstall the wheel and torque lug nuts to specification (usually around 100-120 Nm).

6. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to seat the pads against the rotor.
Check brake fluid level and top off if necessary.
