Brakes are pretty much the most important safety device on your car. If you’ve ever partially lost your brakes in the past, you’ll agree that it’s not something you want to experience again. Inspecting your brakes twice a year for wear and damage can protect you and your passengers. Additionally, it will also help save you money by catching any damage before it becomes too costly.
Brake System Components That Can Fail
The master cylinder, the heart of the vehicle’s braking system, holds the brake fluid when it is not being delivered to the brakes through the brake lines. If brake fluid leaks because the master cylinder is worn or brake lines are plugged or broken, the fluid cannot be delivered, and the brake pads will become ruined.
The brake fluid itself can become dirty or contaminated as it draws rust-causing moisture and picks up other debris, or it can break down from excess heat. Clean brake fluid is either clear or slightly yellow, while dirty brake fluid may be brown or even black. Old and dirty brake fluid can damage ABS brake systems internally.
The brake lines connect to the master cylinder through a combination valve, which combines a metering and proportioning valve. It regulates the pressure on the front and rear wheels to make sure both sets of brakes are applied simultaneously. A malfunctioning combination valve may cause the wheels to lock up.
Brake pads and shoes can be made of ceramic, metal or organic materials, while the disc rotors and drums they press against are made of metal. Because the pads and shoes create friction to stop the car, they gradually wear down over time and may wear away completely, letting the metal of the calipers and cylinders they are attached to grind against the rotors and drums and damage them. Some pads have a metal strip attached that sounds a warning whistle when the pad becomes too worn, but this strip sounds only when the car is in motion and the brakes are not applied.
At NK Motorwerkz, we want our LA customers to have the opportunity to feel comfortable in their vehicle. You can leave the automotive service and repairs to our professionals, but please don’t hesitate to ask us questions about why a service is needed or how it occurred. Our auto mechanics are dedicated to providing the best auto care experience possible, so feel free to give us a call, and we will be happy to speak with you. Here is some valuable information on brake issues and corrective services we offer.
Brake Pad & Shoe Replacement
Brake pad problems can usually be identified by squealing brakes. If your brake pads deteriorate completely, you’ll hear a grinding metal-on-metal sound when braking, meaning that it’s too late and you’re ruining your rotors or drums! Those with knowledge of auto repair may be able to fix this at home, but you should always see an auto repair professional immediately if you have brake problems.
In a disc brake system, rotors are attached to your vehicle’s wheels. When the brake pads grip the rotor, they bring both the rotor and wheels to a stop. However, the friction causes grooves and cracks to appear over time. Resurfacing brings the rotor back to a “like-new” condition, reducing squealing and wobbling. NK Motorwerkz will give your rotors a thorough inspection and recommend your best course of action.
The brake caliper houses your brake pads and fits around the rotor like a clamp, pressing the pads against the rotor when you brake. A brake caliber problem could cause uneven braking, making your car slide forward when you brake. Uneven braking can also cause your vehicle to slide out of control in bad weather conditions, so contact Faxon Garage as soon as possible.
A brake hose is a tube carrying pressurized brake fluid from the master cylinder to the brakes. A crushed hose can cause a lagged or slow brake, and a leak in the hose can cause the brake, or the entire brake system, to fail. These don’t need to be replaced often, but should be replaced at the first sign of cracking or wear.
Brake Fluid Flushes
Brake fluid will absorb water from the air over time, causing the brake system to become less effective and the fluid to become corrosive, possibly damaging the system. It is important to perform a brake fluid flush regularly to ensure that your vehicle is using fresh fluid. Talk to our technicians at NK Motorwerkz about when it’s time for a brake fluid flush.
Anti-Lock Brake System
Anti-lock Brake Systems (ABS) ensure that the wheels don’t stop rotating during braking, preventing the car from skidding and offering greater control. If your ABS light comes on, visit NK Motorwerkz where we will be happy to diagnose and fix the problem.
