my Toyota Camry Eighth Generation (2018-present) brake pedal feels soft, what should I do?

Solution

1. Preparation

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

2. Check and Refill Brake Fluid

• Sub-steps:
  1. Open the hood and locate the brake fluid reservoir.
  2. Remove the cap and check the fluid level; if low, add manufacturer-recommended brake fluid (DOT 3 or DOT 4).
  3. Replace the cap securely.

3. Inspect and Repair Brake Lines

• Sub-steps:
  1. Visually inspect brake lines for any signs of wear, corrosion, or leaks.
  2. If leaks are found, replace the damaged section of the brake line with OEM parts.
  3. Use a line wrench to disconnect and reconnect brake lines to prevent rounding of fittings.

4. Replace Brake Pads (if worn)

• Sub-steps:
  1. Lift the vehicle using a jack and secure it with jack stands.
  2. Remove the wheel to access the brake assembly.
  3. Remove the caliper bolts using a socket set and lift the caliper away.
  4. Remove the old brake pads and inspect the caliper piston for damage.
  5. Install new brake pads, ensuring proper alignment and seating.
  6. Reattach the caliper and torque bolts to the manufacturer's specifications.

5. Brake Booster Inspection

• Sub-steps:
  1. Start the engine and press the brake pedal several times to check for a firm feel.
  2. If the pedal remains soft, inspect the brake booster by checking for hissing noises (indicative of vacuum leaks).
  3. If a leak is detected, replace the brake booster unit.

6. Test and Refill Brake System

• Sub-steps:
  1. Bleed the brake system to remove any air bubbles using a brake bleeder kit.
  2. Refill the brake fluid reservoir to the proper level.
  3. Test drive the vehicle to ensure the brake pedal feels firm.
