Solution

1. Preparation

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

2. Inspect and Top Off Brake Fluid

Tools Required: Brake fluid, funnel
Instructions:
1. Open the hood and locate the brake fluid master cylinder.
2. Remove the cap and inspect the fluid level. If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual) to the recommended level.
3. Replace the cap securely.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, brake fluid
Instructions:
1. Start with the wheel furthest from the master cylinder (right rear).
2. Attach the bleeder kit to the brake caliper bleeder screw.
3. Have an assistant press the brake pedal slowly and hold it down.
4. Open the bleeder screw to allow fluid and air to escape; close the screw before the pedal is released.
5. Repeat this process until no air bubbles are visible in the fluid.
6. Move to the next wheel (left rear, then right front, and finally left front) and repeat the bleeding process.

4. Inspect Brake Components

Tools Required: Socket set, torque wrench
Instructions:
1. Remove the wheels to access the brake components.
2. Inspect the brake pads for wear. Replace if the thickness is below the manufacturer’s specification (usually 3mm).
3. Check the rotors for grooves or warping. Replace if necessary.
4. Ensure caliper pistons are moving freely and are not sticking.

5. Replace Damaged Components

Parts Required: Brake pads, rotors, seals (if necessary)
Instructions:
1. If any components are worn or damaged, replace them with OEM or quality aftermarket parts.
2. Reassemble the brake system, ensuring all fasteners are torqued to manufacturer specifications.
