Disc Brakes Getting Hot on One Side: Common Causes and Solutions

Last updated 3 days ago

If you've ever experienced hot disc brakes, you know how nerve-wracking it can be when you feel that heat emanating from your wheels. The burning smell and vibration can make you wonder if your car is going to make it to your destination. In this article, we’ll discuss the common causes and solutions for disc brakes getting hot on one side.

What is Brake Overheating?

Brake overheating is a common issue where the brake system generates too much heat, causing the brake components to reach high temperatures that lead to poor braking performance. There are several reasons why brakes can overheat, and here are the most common ones:

Friction Between Brake Pads and Rotor

When you press the brake pedal, the hydraulic system applies pressure on the rotor, which generates friction between the brake pads and the rotor. This friction slows down the car and generates heat. If the rotor is not properly lubricated, it can cause the friction to increase, generating more heat than necessary.

Excessive Heat from Braking

The more you use the brakes, the hotter they will get. This is especially true when you are driving downhill or if you are towing a heavy load. The extra weight and resistance cause the brake system to work harder, generating more heat than usual.

Warped or Damaged Brake Disc

If your brake disc is warped or damaged, it can cause the brake pad to rub against the disc unevenly, generating more heat than necessary. This can happen due to poor quality brake discs, improper installation, or a manufacturing defect.

What are the Common Causes of Brake Overheating on One Side?

Worn Out Brake Pads

A worn-out brake pad can cause the caliper piston to push harder on one side of the rotor than the other, leading to uneven pressure and heat distribution. This can cause the brake disc on one side to get hotter than the other side, leading to brake fade and reduced stopping power.

Stuck Caliper

A stuck caliper can cause brake friction on one side of the rotor to be more significant than the other, leading to uneven brake pad wear and heat distribution. This can cause the brake disc on one side to get hotter than the other, leading to brake fade and reduced stopping power.

Uneven Brake Pad Wear

Uneven brake pad wear can cause the brake friction on one side of the rotor to be more significant than the other, leading to uneven heat distribution. This can cause the brake disc on one side to get hotter than the other, leading to brake fade and reduced stopping power. Uneven brake pad wear can happen due to misaligned brake calipers or worn-out brake hardware.

How Can You Fix Brake Overheating on One Side?

Replace Worn-out Brake Pads

If your brake pads are worn-out, replace them right away. This will ensure that your brake system applies even pressure on both sides of the rotor, preventing uneven heat distribution.

Repair or Replace Stuck Caliper

If you have a stuck caliper, you'll need to repair or replace it. A stuck caliper can cause uneven brake friction, leading to uneven heat distribution.

Replace Warped or Damaged Brake Disc

If your brake disc is warped or damaged, you'll need to replace it. A warped or damaged brake disc can cause uneven brake friction, leading to uneven heat distribution.

How Can You Prevent Brake Overheating on One Side?

Regular Brake Maintenance

Regular brake maintenance is crucial to keep your brake system in top shape. This includes checking brake fluid levels, inspecting brake pads and rotors for wear, and ensuring that the brake system is properly lubricated.

Upgrade to High-Performance Brake Pads and Rotors

High-performance brake pads and rotors can help dissipate heat more efficiently, preventing brake overheating on one side. They are also often made with better materials that can withstand high temperatures without warping or cracking.

Use Engine Braking Instead of Riding the Brakes

Engine braking is a technique where instead of riding the brakes, you shift to a lower gear and allow the engine to slow down your car. This reduces the amount of friction generated by the brake system, preventing heat buildup and uneven wear.

What Should You Do if Your Brakes Overheat While Driving?

Stop Driving Immediately and Allow Brakes to Cool Down

If your brakes overheat while driving, stop driving immediately and allow your brakes to cool down. Continuing to drive with overheated brakes can cause permanent damage to the brake system and reduce stopping power.

Check Brake Pads and Rotor for Wear and Damage

Check your brake pads and rotor for wear and damage. Worn-out or damaged components can cause uneven brake friction and heat distribution, leading to overheating.

Have Your Brakes Inspected by a Professional Mechanic

If you're unsure about the condition of your brakes, take them to a professional mechanic for inspection. A professional mechanic can identify any issues with your brake system and recommend the best course of action.
