Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and cooled down.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Brake Components

Remove Wheel
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Inspect Brake Pads and Rotors
- Check the thickness of the brake pads; replace if less than 3mm.
- Inspect rotors for scoring or warping, and replace if necessary.
Replace Brake Pads
- Remove the caliper bolts with a ratchet and socket.
- Slide off the caliper and remove old brake pads.
- Install new brake pads and reattach the caliper, torquing bolts to manufacturer's specifications.

3. Address Fluid Leaks

Identify and Fix Leaks
- Locate the source of any fluid leaks identified during the diagnostic steps.
- Replace any damaged hoses or gaskets.
Top Up Fluid Levels
- Ensure all necessary fluids (engine oil, coolant, brake fluid) are topped up to the correct levels.

4. Replace Worn Belts and Hoses

Inspect all belts and hoses for wear.
Replace any that are frayed or show signs of cracking to prevent future issues.

5. Reconnect Battery

Reconnect the negative battery terminal securely after all repairs are complete.
