Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Check Brake Fluid Level

Remove the master cylinder reservoir cap.
Inspect the brake fluid level; if low, top off with the recommended brake fluid (DOT 3 or DOT 4).
If the fluid is low, investigate for leaks or excessive wear.

3. Inspect Brake Components

Remove the wheel to access the brake components.
Inspect the brake pads for thickness; replace if less than 1/4 inch.
Check the brake rotors for scoring or warping; replace if necessary.
Ensure calipers are not seized and move freely.

4. Repair or Replace Faulty Components

If brake pads are worn, remove the caliper and replace the pads.
If rotors are damaged, remove the caliper and replace the rotors.
If leaks are found, replace damaged brake lines or calipers as needed.
Reassemble all components ensuring proper torque specifications are followed (typically 80-100 ft-lbs for caliper bolts).

5. Refill and Bleed Brake System

Refill the brake fluid reservoir to the proper level.
Bleed the brake system using a brake bleeder kit to remove air from the lines.
Start with the wheel farthest from the master cylinder and work towards the nearest.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check that the brake warning light is off.
Conduct a test drive to ensure proper brake function.
