What’s involved in a brake repair?
Brakes are one of the more critical safety components in a vehicle. They need to be in top condition to ensure smooth stops and prevent accidents on the road. Several brake components wear out over time and require maintenance. But how do brakes work? How do they signal that something is wrong? What can you do to extend their lifespan? Here’s everything you need to know about brake repair and maintenance.
How do brakes work?
Your vehicle’s brakes operate on a hydraulic system, i.e., they need fluid to operate. When pressing the brake pedal, your car’s braking system will engage. Hydraulic brake fluid then transmits pressure from the pedal to the calipers, which squeeze the brake pads against the brake rotors (also known as brake discs). This friction slows the wheels and brings the vehicle to a stop.
Types of brake pads include ceramic, semi-metallic, or organic compounds that can withstand extreme heat and pressure. The brake pads play a crucial role in the braking process. Over time, the constant use will wear them down and reduce their effectiveness, which is why routine inspections and timely repairs or replacements are essential to maintaining braking performance.
Signs your brakes need repair
There are several indications that components of your braking system need to be checked. Here are some of the most common:
Squealing sounds: Worn-out brake pads sometimes emit a high-pitched squealing noise during braking. Most brake pads have a built-in wear indicator that creates the sound to alert the driver that it may be time for replacement. Ignoring the squealing sound leads to a grinding sound that shows the brake pads have completely worn down and are actively damaging the rotors.
Pulsing and vibrations: If your vehicle handling includes strange vibrations or pulsations in the brake pedal or steering wheel while braking, you may have warped rotors. Warping occurs because of frequent hard braking and its subsequent excessive heat buildup.
Spongy brake pedal: A soft, sinking brake pedal could mean a brake fluid issue. Leaks in the hydraulic system, air in the brake lines, or low fluid levels could all cause this problem. Issues with brake fluid must be addressed immediately since brake fluid is essential for transmitting braking force. Keep others—including pets—away from brake fluid.
Car pulls to one side: If your vehicle pulls to one side during braking, it could mean that your brake pads are experiencing uneven wear, or that a brake caliper is sticking.
Burning smell: A strong burning odour that occurs while braking could suggest overheating. This is common after aggressive driving or while descending steep hills. Overheated brakes can lead to reduced stopping power.
What’s involved in a brake repair?
Brake repair services ensure your vehicle stops safely and efficiently. Because the braking system has many components, brake repair can involve several smaller repairs or replacements. We’ll cover several common types of repairs here.
The most common service is brake pad replacement, which swaps old brake pads for new ones to restore the proper braking function in your vehicle. Brake pads should be replaced before they’ve worn down completely to prevent damage to other parts of the braking system.
Sometimes, brake rotors will need resurfacing or replacement. If rotors become excessively worn, they can cause unstable handling or uneven braking. Resurfacing smooths out minor imperfections, while severely worn or warped rotors require full replacement. One of the best ways to protect the rotors from damage is to properly maintain the brake pads.
Brake calipers house the brake pads and press them against the rotors when the driver applies pressure on the brakes. Brake caliper inspection is essential to avoid stuck or malfunctioning calipers that may lead to uneven wear and reduce stopping distance.
A brake fluid flush can be included in a brake service. Brake fluid absorbs moisture overtime, which leads to increased corrosion and decreased braking efficiency. Replacing old fluid supports the hydraulic system’s functions.
Finally, brake line and hose inspections check for any leaks or air bubbles. Compromised braking performance because of these issues must be addressed immediately.
How to extend the life of your brakes
Your brakes are your car’s most important safety feature. Understanding how brake pads work, recognizing signs of wear, and following maintenance tips will help keep you and your vehicle safe.
Brake maintenance is essential for ensuring longevity and optimal braking performance. To extend the life of your brakes, avoid sudden, aggressive braking that increases wear and tear on the brake pads and rotors. Instead, anticipate stops and brake gradually where possible. Flush brake fluid regularly—Many manufacturers will recommend replacing brake fluid every two years.
