Understanding Your Car's Braking System: A Guide by Girlington Garage
Hello, South Burlington! It’s your go-to team from Girlington Garage here to put the brakes on confusion about your car’s braking system. Whether you're commuting to work or heading out on a weekend adventure, knowing how your brakes work is crucial for your safety. Let's break down (no pun intended!) how your car's braking system functions, the factors that affect brake pad lifespan, and how to handle common issues.
How Does Your Car’s Braking System Work?
Understanding the basics of your vehicle's braking system enhances your ability to identify potential issues and communicate more effectively with your mechanic.
Regularly Serviced Components of the Braking System
Your car’s braking system is a whole lot of different parts working together to bring your vehicle to a stop:
Brake Master Cylinder: The brake master cylinder sends the brake fluid out to each wheel through each brake line.
Brake Lines and Fluid: The brake lines are metal tubes that carry brake fluid to each one of your wheels. Pressing on the brake pedal causes the brake fluid to push through those lines. Brake fluid is non-compressible so the force of your foot on the pedal is transmitted through the fluid to the brake calipers.
Brake Calipers: Brake calipers hold your brake pads onto either side of your brake rotors and allow the brake pads to clamp and unclamp on the rotors. When you press on the brake pedal, the fluid that is forced through the brake lines enters the calipers and pushes a set of pistons out against your brake pads. The pressure from the pistons clamps the pads onto the rotors.
Brake Pads and Rotors: Brake pads are essentially small metal rectangles with a thick layer of friction material (a ceramic and metallic mixture) attached to them. The brake rotors are metal discs that are attached to, and spin with the wheels of your car. When the pistons in the calipers clamp the brake pads against the rotors, the friction material on the pads grip the spinning rotors (and thus the spinning wheels) and stop them from spinning. This is how the car comes to a stop. If you want a familiar comparison, your vehicle's pads and rotors are very similar to the brakes on a bicycle.
The Role of ABS (Anti-lock Braking System)
ABS is a safety anti-skid braking system that helps to keep your tires gripping the road as much as possible while braking, and prevents the wheels from locking up (ceasing rotation) to avoid uncontrolled skidding. It uses speed sensors and a series of valves and pumps to control how much pressure is applied to each brake, and ensures maximum stopping power without losing control.
Factors Affecting Brake Pad Lifespan
The friction material on brake pads wears down over time based on many various reasons:
Driving Habits
The way you drive can dramatically impact how long your brake pads last. Frequent heavy braking or riding the brakes can lead to quicker wear and tear.
Environment
Driving in urban areas with lots of traffic lights or in mountainous terrain that requires frequent braking can also reduce the lifespan of your brake pads compared to driving on open highways with minimal stops.
Brake Pad Material
Brake pads are made from various materials, each offering different wear rates, performance levels, and noise/vibration characteristics. Common materials include ceramic, metallic, and organic compounds.
Common Brake Issues and Their Solutions
Squeaking or Grinding Noises
Hearing a high-pitched squeal or a harsh grinding sound when you brake? It’s likely a sign that your brake pads are worn out and need to be replaced. Sometimes, debris caught between the pad and the rotor can also cause noise.
Vibration When Braking
If your steering wheel or the whole vehicle vibrates when you brake, this could indicate warped rotors. Overheating the rotors can cause them to deform, leading to uneven brake pad contact and inefficient braking. It could also indicate excessive rust build up on the braking surface of the rotor. Rust on rotors is a huge problem in Vermont. It can cause premature failure of the pads and rotors, and has been the reason for many Vermont State Inspection failures.
Brake Pedal Feels Soft
A soft or spongy feel in the brake pedal often points to air in the hydraulic system or a problem with the master cylinder. It might require bleeding the brakes to remove the air or replacing the cylinder.
