Brakes: Your Safety System
Definition:
Brakes slow or stop your vehicle by converting kinetic energy into heat.
Location:
Located at each wheel, comprising brake pads, rotors, and calipers.
Function:
- Reduce vehicle speed or bring it to a complete stop
- Maintain control during braking
Types:
- Disc brakes
- Drum brakes
Components:
| Part | Role |
|---|---|
| Brake Pads | Clamp onto rotors to create friction |
| Rotors | Disc-shaped components attached to wheels |
| Calipers | House brake pads and pistons to press pads onto rotors |
| Brake Fluid | Transmits force from pedal to calipers |
Tips for Success:
- Regularly inspect brake pads for wear.
- Bleed brake fluid periodically.
- Avoid aggressive braking to prolong brake life.
Common Mistakes & How to Avoid:
- Ignoring brake warning lights.
- Riding the brake pedal unnecessarily.
- Neglecting signs of brake squeal or reduced responsiveness.
Why It Matters:
Reliable brakes are essential for safety, giving you confidence in stopping distances and control.
Exhaust System: Removing Harmful Gases
Definition:
The exhaust system channels and expels gases produced during combustion.
Location:
Runs beneath the car from the engine to the rear, ending in the muffler.
Function:
