my Honda Pilot YF4 (2023-Present) has poor braking response, what could be the issue?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the parking brake is engaged.
• Disconnect the battery to avoid any electrical issues.

2. Inspect and Replace Brake Fluid

• Sub-steps:
  • Open the hood and locate the master cylinder reservoir.
  • Remove the cap and inspect the fluid level; if low, fill with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
  • If the fluid is dark or contaminated, proceed to flush the system.
  • To flush, connect a brake bleeder kit to the brake caliper bleed screws and have an assistant pump the brake pedal.
  • Open the bleed screw to allow old fluid to escape and close it once new fluid appears.

3. Inspect and Replace Brake Pads and Rotors

• Sub-steps:
  • Lift the vehicle and remove the wheel using a socket set.
  • Remove the caliper bolts and slide the caliper off the rotor.
  • Inspect the brake pads for thickness; if less than 3mm, replace them.
  • Check the rotor for warping or scoring; if damaged, replace.
  • Install new pads and rotors, ensuring to apply anti-squeal grease to the backing of the pads.
  • Reinstall the caliper and torque the bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Master Cylinder (if needed)

• Sub-steps:
  • If the master cylinder is confirmed faulty, remove it by disconnecting the brake lines and unbolting it from the brake booster.
  • Install the new master cylinder and torque to specifications.
  • Reconnect the brake lines, ensuring no leaks occur.
