Solution

1. Preparation

Gather all necessary tools and safety equipment.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Wear safety glasses and gloves.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Locate the master cylinder reservoir under the hood.
Remove the cap and check the fluid level.
If low, add the correct type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Replace the cap securely.

3. Inspect and Replace Brake Pads and Rotors

Tools Required: Socket set, torque wrench, brake pad spreader
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; if less than 3mm, replace.
Check the rotors for scoring or excessive wear; replace if necessary.
Remove the caliper bracket bolts, then the caliper, and replace pads.
Reassemble the caliper and torque bolts to manufacturer specifications.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, container for old fluid
Start at the wheel farthest from the master cylinder (usually the rear passenger side).
Attach the bleeder kit and have an assistant pump the brake pedal until firm.
Open the bleeder valve to release air and old fluid, then close and repeat until no bubbles appear.
Continue bleeding until all wheels are done, ensuring fluid is topped up to avoid air entering.
