Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety glasses and gloves for protection.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, brake bleeder kit.
Check the brake fluid level; if low, top it up with the recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated, proceed to flush and replace it.
- Sub-steps:
  1. Remove the master cylinder cap and use a siphon to extract old brake fluid.
  2. Fill the master cylinder with new brake fluid.
  3. Ensure the cap is securely replaced.

3. Bleed Brake Lines

Tools Required: Brake bleeder kit, wrench, clear tubing.
This step removes air from the brake lines.
- Sub-steps:
  1. Attach the clear tubing to the bleeder valve on the brake caliper.
  2. Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid.
  3. Close the valve before the pedal reaches the floor.
  4. Repeat this process until no air bubbles appear in the tubing.
  5. Move to the next wheel (following the recommended brake bleeding order: RR, LR, RF, LF).
  6. Check and refill the master cylinder as necessary during the process.

4. Inspect and Replace Brake Components (if necessary)

Tools Required: Socket set, torque wrench.
If brake pads or rotors are worn, replace them.
- Sub-steps:
  1. Remove the wheel to access the brake assembly.
  2. Remove the caliper by loosening the mounting bolts and hang it to avoid straining the brake line.
  3. Remove old brake pads and inspect rotors for scoring or warping.
  4. Install new brake pads and reassemble the caliper.
  5. Torque caliper bolts to manufacturer specifications.
