1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Disconnect the battery (negative terminal) for safety.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Inspect the master cylinder reservoir. If the brake fluid is low, refill it with the appropriate brake fluid specified in the owner's manual.
Check for any leaks in the system after refilling.

3. Inspect and Replace Brake Pads

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench
Raise the vehicle and secure with jack stands.
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; replace if less than 3mm.
Remove the caliper bolts and slide the caliper off the rotor.
Replace the brake pads and reassemble the caliper.
Torque the caliper bolts to manufacturer specifications.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged or excessively worn (more than 0.5mm), replace them.
Remove the rotor by unscrewing the retaining screws (if applicable).
Install the new rotor, ensuring it is properly seated and secure.
