Solution

1. Preparation

Gather all tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and securely raise it using jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Repair Brake Fluid System

Tools Required: Brake fluid, funnel, shop towels
Check the brake fluid level in the master cylinder; if low, refill with manufacturer-recommended brake fluid.
Inspect brake lines and hoses for cracks or leaks; replace any damaged components as necessary.

3. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing, container for old fluid
Start with the brake caliper farthest from the master cylinder (usually the right rear).
Attach the tube to the bleed valve and submerge the other end in the container.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleed valve to release air and fluid, then close it before your assistant releases the pedal.
Repeat until no air bubbles are visible in the fluid.
Move to the next caliper (left rear, right front, left front) and repeat the process.

4. Inspect and Replace Brake Components (if necessary)

Tools Required: Socket set, torque wrench
Remove the wheel to access the brake caliper and rotor.
Inspect brake pads for wear; replace if they have less than 3mm of material left.
Check the rotor for grooves or warping; replace if necessary.
Install new pads and rotors, ensuring proper alignment and torque to manufacturer specifications.
