Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.
Wear safety glasses and gloves.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Check the brake fluid reservoir; if low, top off with the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Inspect for leaks. If low fluid persists, further investigation is required.

3. Inspect and Replace Brake Components

Tools Required: Socket set, brake cleaner, torque wrench
Remove the wheel to access the brake caliper and rotor.
Inspect brake pads for wear; replace if the thickness is below the manufacturer's minimum specification.
Check the rotor for grooves or warping; resurfacing or replacement may be necessary.
Reassemble components, ensuring all bolts are torqued to specification.

4. Test and Replace Brake Booster

Tools Required: Vacuum gauge, wrench set
Disconnect the brake booster vacuum line and check for leaks.
If the booster is faulty, remove it by unbolting it from the firewall and disconnecting the pushrod from the brake pedal.
Install the new brake booster and reconnect all lines.
