Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid electrical issues during repairs.

2. Inspect and Replace Brake Fluid

Remove the reservoir cap and check the brake fluid level.
If low, top up with the manufacturer-recommended DOT brake fluid.
If the fluid is contaminated, flush the brake system by:
- Removing the brake bleeder screws on each caliper.
- Using a brake bleeding kit or a vacuum pump to remove old fluid.
- Refill the master cylinder and bleed the brakes until new fluid flows from each caliper.

3. Check and Replace Brake Booster (if necessary)

Disconnect the vacuum line from the brake booster.
Remove the retaining nuts securing the brake booster to the firewall.
Carefully pull the brake booster out of the vehicle.
Install the new brake booster by reversing the removal process, ensuring the vacuum line is properly connected.

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

Remove the wheel to access the brake caliper.
Remove the caliper bolts and lift the caliper away from the rotor.
Inspect the brake pads for wear; if they are below the minimum thickness, replace them.
Inspect the rotor for scoring or warping; replace if necessary.
Reassemble the caliper and wheel, ensuring all components are secure.
