Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Wear safety goggles and gloves.

2. Inspect the Brake Fluid

Open the hood and locate the brake master cylinder.
Check the fluid level; if it’s low, top it off with the manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
Inspect for any signs of fluid contamination.

3. Identify and Repair Leaks

Visually inspect all brake lines, hoses, and connections for leaks.
If any leaks are found, replace the damaged components.
- Tools Required: Wrench set, brake line cutter.
Tighten any loose fittings.

4. Bleed the Brake System

Start at the wheel farthest from the master cylinder (usually the right rear).
Attach a clear hose to the bleeder valve and submerge the other end in a container filled with brake fluid.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to release air and fluid; close it before the assistant releases the pedal.
Repeat until no air bubbles are present, and fluid runs clear.
Repeat for each wheel in the order: right rear, left rear, right front, left front.
Tools Required: Brake bleeder kit, clear tubing, wrench.

5. Inspect Brake Pads and Rotors

Remove the wheel to access the brake components.
Measure the thickness of the brake pads; replace if they are below the manufacturer’s specifications.
Inspect the rotors for scoring or warping; replace if necessary.
Tools Required: Jack and jack stands, lug wrench, caliper tool.

6. Check the Brake Booster

With the engine off, pump the brake pedal several times to deplete vacuum.
Hold the pedal down and start the engine; the pedal should drop slightly if the booster is working correctly.
If it does not drop, the brake booster may need replacement.
Tools Required: Basic hand tools.
