Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the battery to prevent any electrical shorts.
2. Inspect and Replace Brake Fluid
  • Sub-steps:
    • Remove the brake fluid reservoir cap and check the fluid condition. If it appears dark or contaminated, it should be replaced.
    • Use a brake fluid syringe to extract old fluid from the reservoir.
    • Fill the reservoir with the recommended brake fluid (DOT 4 for Clio V).
  • Tools Required: Brake fluid syringe, clean cloth.
3. Inspect and Replace Brake Pads
  • Sub-steps:
    • Remove the wheel to access the brake caliper.
    • Unbolt the caliper and carefully hang it to avoid straining the brake line.
    • Inspect the brake pads for wear; replace if they are worn below the specified thickness (usually 3mm).
    • Install new brake pads, ensuring they are properly seated.
  • Tools Required: Socket set, torque wrench.
4. Bleed the Brake System
  • Sub-steps:
    • Begin at the wheel farthest from the master cylinder (usually the rear passenger side).
    • Use a brake bleeder kit to connect to the bleeder valve on the caliper.
    • Have an assistant pump the brake pedal, then hold it down while you open the bleeder valve to release air and old fluid.
    • Repeat until clear fluid without bubbles emerges, then tighten the bleeder valve.
    • Repeat for each wheel in the correct order.
  • Tools Required: Brake bleeder kit, wrench for bleeder valves.
5. Reassemble and Test
  • Sub-steps:
    • Reinstall the caliper and wheel.
    • Reconnect the battery and ensure all tools are removed from the engine bay.
    • Test the brake pedal feel and perform a test drive to check for improvements.
  • Tools Required: Socket set.
