Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and the vehicle is cool.

2. Inspect and Replace Brake Pads

Tools Required: Jack and jack stands, lug wrench, socket set, brake pad spreader.
Remove the wheel to access the brake caliper.
Use a socket set to remove the caliper bolts and carefully slide the caliper off the rotor.
Inspect the brake pads for wear; if they are worn down to less than 1/4 inch, replace them.
Install new brake pads by sliding them into position and reattach the caliper using the original bolts, ensuring they are torqued to manufacturer specifications.

3. Check and Replace Brake Fluid

Tools Required: Brake fluid reservoir, turkey baster for removal, new brake fluid (DOT 3 or DOT 4 as specified).
Open the brake fluid reservoir cap and use the turkey baster to remove old fluid.
Fill the reservoir with new brake fluid to the recommended level.
Bleed the brakes to remove any air bubbles if necessary.

4. Inspect Brake Booster and Vacuum Lines

Tools Required: Visual inspection tools (flashlight).
Locate the brake booster located at the rear of the engine bay.
Inspect for any visible cracks or leaks in the vacuum lines connected to the brake booster.
If damaged, replace the vacuum lines and the brake booster as needed.

5. Throttle Body Inspection

Tools Required: Socket set, throttle body cleaner.
Disconnect the negative battery terminal.
Remove the air intake duct to access the throttle body.
Inspect the throttle body for carbon buildup and clean it using throttle body cleaner.
Reattach all components and reconnect the battery.
