1. Hydraulic System: The heart of the system. When you press the brake pedal, you're pushing a piston in the master cylinder. This increases the hydraulic pressure in the brake lines.
2. Brake Lines: These steel tubes carry the hydraulic pressure from the master cylinder to the wheels. Any leaks in these lines will severely compromise braking ability.
3. Wheel Cylinders (Rear) / Calipers (Front): These are the actuators at each wheel.
* Wheel Cylinders (Rear): In many Windstar models, the rear brakes use drum brakes. The pressure from the brake lines pushes pistons in the wheel cylinder, forcing brake shoes outward against the drum, creating friction and slowing the wheel.
* Calipers (Front): The front brakes almost certainly use disc brakes. Hydraulic pressure forces pistons in the caliper to squeeze brake pads against a spinning rotor (disc), creating friction and slowing the wheel.
4. Brake Pads/Shoes: These are the friction materials that actually slow the wheels down. They wear down over time and need to be replaced.
5. Rotors/Drums: These are the metal parts that the brake pads or shoes rub against. Rotors (disc brakes) can wear down and become warped, reducing braking effectiveness. Drums (drum brakes) can also wear and require replacement or machining.
6. Brake Pedal: This is your interface with the braking system. Its feel (spongy, hard, etc.) can indicate problems with the system.
7. Booster (Vacuum Assist): This assists you in applying the brakes, making it easier to stop, especially in emergencies. A failing booster will result in a very hard brake pedal.
Important Considerations for your Windstar:
* Regular Maintenance: Brake pad/shoe replacement is crucial. Have them inspected during routine service.
* Brake Fluid: Brake fluid absorbs moisture over time, which can reduce its effectiveness and lead to corrosion. It should be flushed and replaced periodically (consult your owner's manual).
* Warning Lights: Pay close attention to any brake warning lights on your dashboard. They indicate a potential problem that needs immediate attention.
* Professional Service: Brake repair can be complex. If you suspect a problem, have it checked by a qualified mechanic.
This is a simplified overview. For detailed information specific to your Windstar's year and model, consult your owner's manual or a reputable automotive repair manual. Your safety depends on a properly functioning braking system.
