Solution

1. Preparation

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

2. Inspect and Top Off Brake Fluid

Tools Required: Brake fluid, funnel
Remove the master cylinder cap and check the fluid level; top off with the recommended brake fluid type if low.
Inspect the cap and rubber seal for damage before reinstallation.

3. Check for Leaks

Tools Required: None
Visually inspect brake lines, hoses, and fittings for any signs of fluid leaks.
Check the master cylinder for any signs of seepage.

4. Bleed Brake Lines

Tools Required: Brake bleeder kit, container for old fluid
Begin at the wheel farthest from the master cylinder (usually the rear passenger side):
1. Attach the bleeder kit to the brake caliper.
2. Open the bleed screw while an assistant presses the brake pedal down.
3. Close the bleed screw before the pedal is released.
4. Repeat until a steady stream of fluid without air bubbles is achieved.
5. Move to the next closest wheel and repeat until all brakes are bled.
Ensure to top off the brake fluid reservoir after each wheel.

5. Inspect Brake Components

Tools Required: Socket set, torque wrench
Remove the wheel to access the brake caliper and rotor.
Inspect brake pads for thickness, replacing if worn below manufacturer specifications.
Check rotors for scoring or warping; replace if necessary.
