Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean rags.
Check the brake fluid level; if low, fill to the appropriate level with the manufacturer-recommended fluid type (typically DOT 3 or DOT 4).
If the fluid appears dark or contaminated, proceed to replace it:
- Use a brake bleeder kit to remove old fluid from the system.
- Fill the master cylinder with new brake fluid and bleed the brakes, starting from the farthest wheel from the master cylinder (usually right rear, left rear, right front, left front).
- Ensure no air bubbles are present in the fluid.

3. Inspect Brake Components

Tools Required: Socket set, torque wrench, brake cleaner, wire brush.
Remove the wheel to access the brake assembly.
Inspect brake pads for thickness; replace if below 3mm.
Clean the rotors using brake cleaner and inspect for scoring or warping; replace if necessary.
Reinstall the wheel and torque to the manufacturer’s specifications.

4. Check the Brake Booster

Tools Required: Vacuum gauge, soapy water.
Inspect the brake booster for any visible cracks or leaks.
Using a vacuum gauge, check if the booster holds vacuum; if it does not, replace the brake booster.
Test for vacuum leaks by applying soapy water to vacuum hoses and checking for bubbles.

5. Reassemble and Test

Reconnect the negative battery terminal.
Test the brake pedal feel; it should feel firm without significant travel.
Perform a test drive to ensure the brakes respond promptly without delay.
