Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Tools Required: Jack and jack stands, socket set, brake cleaner, brake fluid, and a torque wrench.

2. Inspect and Replace Brake Fluid

Remove the master cylinder cap and check the brake fluid level.
If the fluid is low, top it up with the manufacturer-recommended brake fluid.
If the fluid appears dirty or contaminated, proceed to replace it.
- Sub-steps:
  1. Bleed the brakes starting from the furthest wheel from the master cylinder (usually the rear passenger).
  2. Attach a clear hose to the bleeder screw on the brake caliper.
  3. Open the bleeder screw and have an assistant press the brake pedal until fluid flows through the hose.
  4. Close the bleeder screw and repeat until clear fluid is observed, ensuring to keep the master cylinder reservoir filled.

3. Inspect and Replace Brake Components

Check brake pads and rotors for excessive wear.
- Sub-steps:
  1. Remove the wheel to access the brake assembly.
  2. Measure the thickness of the brake pads and inspect the rotors for grooves or warping.
  3. Replace any pads that are below the manufacturer’s minimum thickness.
  4. Resurface or replace rotors as needed.
  5. Reassemble the brake components and wheel.

4. Inspect and Repair Brake Lines

Examine brake lines for leaks or damage.
- Sub-steps:
  1. Look for any signs of fluid leakage or corrosion.
  2. Replace any damaged brake lines using new lines and fittings.
  3. Ensure all connections are secure and properly torqued.
