Brakes not working in cold weather – If you live in climates where cold weather is common, then it could cause problems for your brakes. Now mechanically speaking, cold temperatures don’t actually ruin your vehicle’s brakes. But what they can do is cause your brake rotors and pads to wear out faster.

The reason for this has to do with the slippery conditions of the roads when there is ice, snow or slush on them. When a vehicle’s tires move over a slippery road, it will cause its brakes to work less effectively.
Aggressive driving in these conditions will eventually cause your brake pads to form cracks in them. Some brake pad materials are more prone to cracks than others. Once these cracks form, dirt, water, and cold air from the outside will get into the cracks of your brake pads.

Then these elements will find their way to your brake lines and ultimately impair the brakes. The cold air will end up freezing the brake lines which will create noticeable noises like grinding and squeaking after you step on the brake pedal.

That is why every auto mechanic will tell you that replacing your brake pads periodically is essential in order to protect the brake lines of your vehicle. This goes double for people who live in colder areas.

You should have a diagnostic test performed on your car at least every six months if you experience lots of cold weather, especially if the weather creates ice and snow on the roads. If you notice the symptoms of faulty brake pads and you ignore the problem, then it will eventually cause damage to your brake rotors.

You may be able to get the rotors resurfaced but more likely, an expensive rotor replacement will be needed. But furthermore, you are putting your life and the lives of your passengers in danger if you continue to drive on slippery roads with brake pads that have cracks in them.

The good news is brake pads typically cost about $50 for parts alone. The labor will likely cost another $50 to $100 per axle. So if you get to a brake shop or auto repair shop before any serious damage is done, then replacing your brake pads should cost you under $200 (less if you change them yourself).

This is a very reasonable amount when you consider the damage it can cause your brakes if you were to let them get ruined from these cracks. As for those who live in warm climates, you should still have your brake pads checked once per year because predominately hot areas can still get cold during the winter season of the year.

Can Brake Lines Freeze in Cold Weather?

Yes, brake lines can in theory freeze in cold weather, although it is extremely rare. It would have to get to about 40 or 50 degrees below zero for that to happen.However, if tiny cracks or small holes develop in the brake lines due to prolonged exposure to severe weather or a previous accident, moisture can make its way into the brake lines and mix with the brake fluid. If enough moisture is present, the now diluted brake fluid can freeze much sooner.

Brakes not working in cold weather FAQs

Why do brakes sometimes not work properly in cold weather?

In cold weather, there are several factors that can contribute to brake-related issues. One common problem is the freezing of moisture or condensation inside the brake lines and components. When water freezes, it can block or restrict the flow of brake fluid, leading to reduced braking performance. Additionally, cold temperatures can cause the brake fluid to thicken, making it less effective in transferring hydraulic pressure and slowing down the vehicle. Cold weather can also affect the brake pads and rotors, reducing their friction and making it harder to stop the vehicle efficiently.

How can I prevent my brakes from malfunctioning in cold weather?

To minimize the chances of brake issues in cold weather, it is important to take proper care of your vehicle. Here are some preventive measures:
1. Use winter-grade brake fluid: Winter-grade brake fluid has a lower freezing point than regular brake fluid, reducing the risk of freezing in cold temperatures.
2. Keep your vehicle in a garage or use a car cover: Parking your vehicle in a sheltered area can help prevent moisture buildup and keep the brakes warmer.
3. Allow sufficient warm-up time: Before driving in cold weather, let your vehicle warm up for a few minutes to help warm up the brakes and fluid.
4. Drive cautiously: Increase your following distance and reduce your speed when driving in cold weather, allowing more time for braking and avoiding sudden stops.
5. Schedule regular brake maintenance: Regularly inspect and maintain your vehicle’s brakes, including checking the brake pads, rotors, and brake fluid levels, to ensure they are in good working condition.

What should I do if my brakes fail in cold weather?

If your brakes fail in cold weather, it is crucial to remain calm and take immediate action to ensure your safety. Here’s what you can do:
1. Downshift and use engine braking: If you have a manual transmission, downshift to lower gears to help slow down the vehicle. This technique is called engine braking and can provide some stopping power.
2. Pump the brakes: Rapidly pump the brake pedal several times to build up brake pressure. This may help restore some braking ability temporarily.
3. Engage the emergency brake: Gradually and carefully engage the emergency brake to slow down the vehicle. Be aware that this method may cause your vehicle to skid, so use it cautiously.
4. Look for a safe area to stop: Scan your surroundings for a safe place to stop, such as an empty parking lot or the side of the road. Use your signals and carefully maneuver your vehicle to that location.
5. Use other means of stopping: If all else fails, use any available means to slow down and stop your vehicle, such as rubbing the tires against curbs or driving onto a soft surface like snow or grass.

Should I attempt to fix the brakes myself if they are not working in cold weather?

It is generally not recommended to attempt fixing brake issues yourself, especially if you are not experienced in automotive repairs. Brake systems are complex and critical for your safety, and any mistakes or improper repairs can lead to further damage or accidents. It is best to have your vehicle inspected and repaired by a qualified mechanic or technician who can diagnose the specific problem and perform the necessary repairs or replacements.

Can using a different type of brake fluid improve brake performance in cold weather?

Using a winter-grade brake fluid can help improve brake performance in cold weather. Winter-grade brake fluid is designed to have a lower freezing point and better fluidity in low temperatures. It can help prevent the brake fluid from thickening and ensure that it flows smoothly, maintaining optimal braking performance. However, it is important to note that simply changing the brake fluid may not entirely resolve the issue if there are other underlying problems with the brake system. If you suspect brake issues in cold weather, it is recommended to consult with a professional mechanic who can assess the situation and provide appropriate recommendations.

Can warming up my vehicle before driving improve brake performance in cold weather?

Yes, allowing your vehicle to warm up before driving can help improve brake performance in cold weather. When you start your vehicle and let it idle for a few minutes, the engine generates heat that can warm up the brake system. Warmer brakes and fluid have better efficiency, allowing them to function more effectively. However, keep in mind that warming up your vehicle is primarily beneficial for the engine and other mechanical components. It is still essential to drive cautiously and adapt your braking technique to the cold weather conditions.

Is it normal for brakes to feel different in cold weather?

Yes, it is normal for brakes to feel different in cold weather due to the factors mentioned earlier. Cold temperatures can cause the brake fluid to thicken, reducing its ability to transfer hydraulic pressure and resulting in a spongy or less responsive brake pedal feel. Additionally, the cold can affect the friction between the brake pads and rotors, requiring more pressure on the pedal to achieve the same level of braking force. It is important to be aware of these changes and adjust your driving accordingly, allowing for longer stopping distances and applying brakes more gently in cold weather.

What should I do if I notice reduced braking performance in cold weather?

If you notice reduced braking performance in cold weather, it is essential to address the issue promptly. Here’s what you can do:
1. Drive cautiously: Increase your following distance and reduce your speed to allow for longer stopping distances.
2. Warm up the brakes: Before driving, gently apply the brakes a few times to generate friction and heat, which can help improve braking performance.
3. Have your brakes inspected: Schedule an appointment with a professional mechanic to inspect your brake system for any issues such as worn brake pads, damaged rotors, or low brake fluid levels.
4. Consider using winter-grade brake fluid: Consult with a mechanic to determine if switching to winter-grade brake fluid is suitable for your vehicle and can enhance cold weather braking performance.
5. Follow recommended maintenance: Stick to your vehicle’s recommended maintenance schedule, including regular brake inspections, pad replacements, and fluid flushes to ensure optimal brake performance in all weather conditions.
