Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
  • Disconnect the battery to prevent electrical issues.
2. Brake Fluid Inspection
  • Remove the master cylinder cap and check the brake fluid level.
  • If low, top off with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
3. Leak Repair
  • If leaks are found in brake lines or at the calipers, replace the damaged sections:
    • Use a wrench to disconnect the affected brake line.
    • Install the new line and tighten to the manufacturer’s torque specification (typically around 10-15 ft-lbs).
    • Ensure all connections are secure and leak-free.
4. Brake Pad and Rotor Replacement
  • Remove the wheel to access the brake assembly.
  • Use a socket set to remove caliper bolts and slide the caliper off the rotor.
  • Replace worn brake pads with new ones. Ensure the pads are installed correctly (check orientation).
  • Inspect the rotor for grooves or damage; replace if necessary.
  • Reinstall the caliper and tighten bolts to torque specifications (usually 20-25 ft-lbs).
5. Brake Booster Check
  • Check the brake booster by pressing the brake pedal multiple times with the engine off, then starting the engine.
  • If the pedal sinks significantly, the booster may be faulty and should be replaced:
    • Remove the master cylinder and disconnect the vacuum line.
    • Unbolt the brake booster from the firewall and remove it.
    • Install a new booster and reconnect all components.
6. Final Assembly and Testing
  • Refill the brake fluid reservoir with fresh fluid.
  • Bleed the brakes to remove any air in the system:
    • Start at the wheel farthest from the master cylinder (usually rear passenger side).
    • Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve.
  • Repeat for each wheel in order: rear passenger, rear driver, front passenger, front driver.
