Solution
1. Preparation
  • Gather tools: OBD-II scanner, brake fluid, socket set, multimeter, transmission fluid.
  • Ensure vehicle is parked on a level surface and set the parking brake.
2. Inspect and Replace Brake Fluid
  1. Open the hood and locate the brake master cylinder.
  2. Remove the cap and check the brake fluid level. If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
  3. If the fluid is dark or contaminated, perform a brake fluid flush:
    • Disconnect the brake lines from the master cylinder.
    • Bleed the brake system starting from the furthest wheel to the nearest.
    • Refill and bleed until clear fluid is observed.
  4. Replace the cap securely.
3. Check and Replace Brake Booster
  1. Inspect the brake booster for any visible cracks or leaks.
  2. Disconnect the vacuum line from the brake booster.
  3. Test the brake booster by pressing the brake pedal; if it doesn't hold pressure, it needs replacement.
  4. Unscrew the retaining nuts and remove the brake booster from the firewall.
  5. Install the new brake booster and reconnect the vacuum line.
4. Inspect and Replace Transmission Fluid
  1. Locate the transmission fluid dipstick (if applicable) or the fluid fill plug.
  2. Remove the dipstick or fill plug and check the fluid level; if low, add the appropriate transmission fluid.
  3. If the fluid is burnt or discolored, perform a fluid change:
    • Drain the old transmission fluid by removing the drain plug.
    • Replace the drain plug with a new gasket.
    • Refill with the recommended transmission fluid through the dipstick or fill plug.
5. Electronic System Reset
  1. Reconnect the battery if it was disconnected.
  2. Use the OBD-II scanner to clear any trouble codes related to the brake or transmission systems.
  3. Perform a calibration of the brake and transmission control modules if necessary.
