Solution

1. Preparation

Gather tools and parts needed.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the electrical components.

2. Brake Fluid Inspection

Remove the master cylinder cap.
Check the brake fluid level; if low, top off with manufacturer-recommended brake fluid.
If the fluid appears contaminated, proceed to replace it.

3. Brake Pad and Rotor Replacement

Tools Required: Jack and jack stands, socket set, torque wrench, brake cleaner, bungee cords.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake assembly.
Remove caliper bolts and carefully slide the caliper off the rotor. Use bungee cords to hang the caliper without stressing the brake line.
Inspect brake pads for thickness; replace if less than 3mm.
Remove the rotor by unscrewing it from the hub (if applicable) and replace with a new rotor, ensuring it is clean and free of debris.
Reinstall the caliper and torque bolts to manufacturer specifications.

4. Brake Bleeding

Tools Required: Brake bleeder kit.
Reconnect the battery.
Start at the wheel furthest from the master cylinder, typically the right rear.
Have an assistant press the brake pedal while you open the bleeder screw on the caliper to remove air from the system; close the screw before releasing the pedal. Repeat until no air bubbles appear.
Move to the next wheel and repeat the process until all wheels have been bled.

5. Final Checks

Reinstall the wheel and lower the vehicle.
Ensure all components are secure and check the brake fluid level again, topping up if necessary.
