Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Check and Replace Brake Fluid

Tools Required: Brake fluid, funnel, rags
Remove the brake fluid reservoir cap.
Inspect the brake fluid; if it appears dark or contaminated, drain and replace it with new brake fluid (DOT 4 recommended).
Refill the reservoir to the appropriate level and replace the cap.

3. Inspect and Replace Brake Pads

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; if they are below 3mm, replace them.
Remove the caliper bolts and slide the caliper off the rotor.
Remove old brake pads and install new ones, ensuring proper orientation.
Reattach the caliper and torque the bolts to the manufacturer’s specifications.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are worn beyond manufacturer specifications (check for warping or scoring), replace them.
Remove the caliper bracket if necessary, then slide off the rotor.
Install new rotors, ensuring they are clean and free of debris.
Reassemble the caliper and wheel.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check that the brake warning light is off.
Conduct a test drive to ensure brakes function properly.
