Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety.

2. Inspect and Replace Brake Components

Lift the Vehicle
- Use a hydraulic jack to lift the front of the vehicle.
- Secure it with jack stands for safety.
Remove Wheels
- Use a socket set to remove the lug nuts and take off the front wheels.
Inspect Brake Pads and Rotors
- Check the condition of the brake pads (look for uneven wear).
- Measure rotor thickness using a caliper; replace if below specifications.
Replace Brake Pads (if necessary)
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads and install new ones.
- Apply brake grease to the backing of the pads to prevent noise.
Reinstall Caliper and Wheels
- Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
- Reinstall the wheels and torque the lug nuts to the specified value.

3. Brake Fluid and Lines

Check and Replace Brake Fluid
- Inspect the brake fluid reservoir; if low, top off with the correct type of fluid (DOT 3 or DOT 4).
- If contaminated, perform a brake fluid flush.
Inspect Brake Lines
- Look for any signs of leaks or damage in the brake lines.
- Replace any damaged lines with new ones.
