1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely lift it using a jack and jack stands.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid (DOT 3 or DOT 4), funnel
Open the brake fluid reservoir cap.
Inspect the fluid level; if low, top it off with the appropriate brake fluid.
Replace the cap securely.

3. Bleed the Brakes

Tools Required: Brake bleeder kit, wrench, clear tubing
Start with the rear passenger side brake, attach the clear tubing to the bleeder valve.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve slowly to release air and old fluid until clear fluid appears, then close the valve.
Repeat for each wheel in the order: rear passenger, rear driver, front passenger, front driver.
Ensure to top off the brake fluid reservoir as needed during the process.

4. Inspect and Replace Brake Components if Necessary

Tools Required: Socket set, torque wrench
Remove the wheel to access the brake assembly.
Inspect brake pads for thickness; replace if less than 3 mm.
Check the condition of rotors; replace if warped or worn beyond specifications.
Reassemble components, ensuring all bolts are torqued to manufacturer specifications.

5. Test Brake Functionality

Reinstall the wheel and lower the vehicle.
Test the brake pedal feel; it should feel firm.
Perform a brake test while driving at low speed to ensure proper function before normal use.
