why does my Toyota Camry Eighth Generation (2018-present) brake pedal feel soft

Solution

1. Preparation

• Gather tools: brake fluid, wrench set, brake bleeder kit, and OBD-II scanner.
• Ensure the vehicle is on a level surface and securely supported with jack stands.

2. Inspect and Replace Brake Fluid

• Sub-steps:
  1. Remove the brake fluid reservoir cap.
  2. Check the fluid level against the minimum and maximum marks.
  3. If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
  4. If the fluid is dark or contaminated, proceed to flush the brake fluid system.

3. Bleed Brake Lines

• Sub-steps:
  1. Locate the brake bleeder valves on each brake caliper.
  2. Attach a clear hose to the bleeder valve and place the other end into a container.
  3. Have an assistant pump the brake pedal and hold it down.
  4. Open the bleeder valve to release air and fluid, then close it before the pedal is released.
  5. Repeat this process until clear fluid flows without bubbles, starting from the farthest caliper to the closest (right rear, left rear, right front, left front).
  6. Check and top off the master cylinder fluid level as needed during the process.

4. Inspect and Replace Brake Components (if necessary)

• Sub-steps:
  1. Remove the wheel to access the brake calipers.
  2. Inspect brake pads for thickness; replace if below 3mm.
  3. Inspect rotors for scoring or warping; replace if necessary.
  4. Reassemble the brake components, ensuring proper torque specifications (typically around 80-100 ft-lbs for caliper bolts).

5. Finalize and Test

• Sub-steps:
  1. Replace the brake fluid reservoir cap.
  2. Lower the vehicle from jack stands.
  3. Test the brake pedal feel before driving.
  4. Perform a test drive to confirm proper brake operation.
