my Genesis G70 brakes feel spongy what should I check

Solution

1. Preparation

• Tools Required: Jack, jack stands, socket set, brake fluid, brake bleed kit, wrench set, safety goggles, and gloves.
• Sub-steps:
  1. Park the vehicle on a level surface and engage the parking brake.
  2. Gather tools and materials needed for the repair.
  3. Wear safety goggles and gloves for protection.

2. Check and Refill Brake Fluid

• Sub-steps:
  1. Locate the master cylinder reservoir under the hood.
  2. Remove the cap and check the brake fluid level. If low, top it off with the manufacturer's recommended brake fluid.
  3. Replace the cap securely.

3. Inspect and Repair Leaks

• Sub-steps:
  1. Visually inspect all brake lines and hoses for signs of leakage or damage.
  2. Tighten any loose connections and replace any damaged lines or fittings.
  3. If leaks are found, replace the affected components and ensure connections are tight.

4. Bleed the Brake System

• Sub-steps:
  1. Start at the brake furthest from the master cylinder (usually the passenger rear).
  2. Attach the brake bleed kit to the bleeder valve on the brake caliper.
  3. Have an assistant press the brake pedal while you open the bleeder valve, allowing fluid and air to escape.
  4. Close the valve, instruct your assistant to release the pedal, then repeat until no air bubbles appear in the fluid.
  5. Move to the next brake in sequence (driver rear, passenger front, driver front) and repeat the process.

5. Inspect and Replace Brake Components

• Sub-steps:
  1. Check the condition of brake pads and rotors. Replace if worn beyond specifications.
  2. Reassemble any components removed during inspection and ensure everything is torqued to manufacturer specifications.
