Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to avoid electrical issues during repairs.

2. Check and Replace Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir and remove the cap.
2. Inspect the fluid level; if low, add the recommended DOT brake fluid (usually DOT 3 or DOT 4).
3. If fluid appears dark or contaminated, proceed to replace it.
4. Use a brake bleeder kit to remove old brake fluid from the system.
5. Refill the master cylinder with fresh brake fluid to the appropriate level.

3. Inspect and Replace Brake Pads and Rotors (if necessary)

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake assembly.
3. Check the thickness of the brake pads; replace if less than 3mm.
4. Inspect rotors for scoring or warping; replace if necessary.
5. Install new brake pads and, if needed, new rotors.
6. Reassemble the brake assembly and wheel.

4. Bleed the Brake System

Sub-steps:
1. Begin bleeding the brakes starting from the wheel farthest from the master cylinder (usually the right rear).
2. Attach a brake bleeder kit to the bleed valve on the caliper.
3. Have an assistant press the brake pedal several times, then hold it down.
4. Open the bleed valve to let air and old fluid escape, then close it before releasing the pedal.
5. Repeat this process for all wheels in the correct order (right rear, left rear, right front, left front).
6. Ensure the brake fluid reservoir is kept topped up during the process.
