Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues during the repair.

2. Fluid Inspection and Replacement

Tools Required: Brake fluid, clean rags, funnel
Check the brake fluid level in the master cylinder reservoir.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner's manual).
Inspect the fluid for contamination. If dirty or discolored, proceed to replace the fluid.

3. Brake Bleeding

Tools Required: Brake bleeder kit, wrench, clear tubing
Attach the clear tubing to the brake bleeder valve on the caliper.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to release air and old fluid, then close it while the pedal is held down.
Repeat this process until clear, bubble-free fluid emerges.
Do this for all four wheels, starting from the wheel farthest from the master cylinder (typically the rear passenger side).

4. Inspect and Replace Components (if necessary)

Tools Required: Socket set, torque wrench, brake pads/rotors (if needed)
Remove the wheel to access the brake assembly.
Inspect the brake pads and rotors for wear; replace if they are below the minimum thickness.
Reassemble the brake components and wheel, ensuring everything is torqued to manufacturer specifications.
