why does my Genesis G70 brake pedal feel soft

Solution

1. Preparation

• Gather tools and materials needed for the repair.
• Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
• Wear safety gloves and goggles.

2. Inspect and Top Off Brake Fluid

• Locate the brake fluid master cylinder reservoir.
• Remove the cap and check the fluid level; top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4 as specified).
• Replace the cap securely.

3. Check for Leaks

• Visually inspect all brake lines, fittings, and connections for signs of fluid leaks.
• If leaks are found, replace the damaged components (lines, calipers, or hoses) as necessary.

4. Bleed the Brake System

• Begin at the wheel farthest from the master cylinder (usually the right rear).
• Attach a clear hose to the bleeder valve and place the other end in a container.
• Open the bleeder valve and have an assistant depress the brake pedal repeatedly until clear fluid without bubbles flows through the hose; close the valve.
• Repeat for the left rear, right front, and left front wheels in that order.
• Ensure the master cylinder does not run low on fluid during the process.

5. Inspect Brake Components

• Remove the wheel to access brake pads and rotors.
• Measure the thickness of brake pads; replace if below the minimum specification.
• Inspect rotors for warping or damage; replace if necessary.

6. Verify Brake Booster Function

• Check the brake booster by applying pressure on the brake pedal while the engine is off and then starting the engine.
• If the pedal drops significantly, the booster is functioning properly. If not, the booster may need replacement.
