Solution

1. Preparation

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

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean cloths.
Instructions:
1. Remove the master cylinder cap and check the brake fluid condition; it should be clear and at the correct level.
2. If fluid is contaminated or low, clean the reservoir opening and add the appropriate DOT brake fluid.
3. Secure the cap back on.

3. Bleed the Brake System

Tools Required: Brake bleeder kit or hose, wrench, brake fluid.
Instructions:
1. Start with the wheel farthest from the master cylinder (usually the rear passenger side).
2. Attach the bleeder hose to the brake bleeder valve on the caliper and place the other end into a container.
3. Have an assistant press the brake pedal several times and hold it down.
4. Open the bleeder valve with the wrench to release air and fluid, then close it before the pedal is released.
5. Repeat until no air bubbles are visible in the fluid; check fluid level in the master cylinder regularly.
6. Move to the next wheel and repeat until all brakes are bled.

4. Inspect and Replace Brake Components

Tools Required: Socket set, jack stands, tire iron, brake pads/rotors if needed.
Instructions:
1. Raise the vehicle and remove the wheel.
2. Inspect brake pads for thickness and replace if they are worn down to the indicators.
3. Check rotors for warping or scoring; replace if necessary.
4. Reassemble the wheel and lower the vehicle.

5. Check Master Cylinder and Brake Booster

Tools Required: Wrench, vacuum gauge (if applicable).
Instructions:
1. Inspect the master cylinder for leaks around the seals and connections; replace if leaking.
2. Test the brake booster by pumping the brake pedal several times while the engine is off, then hold the pedal and start the engine. The pedal should drop slightly if the booster is working properly.
3. If the booster is malfunctioning, replace it.
