Why Does My Car Vibrate When Braking at High Speed?

Braking at high speed and your car is shaking, and you are wondering what on earth could be happening? Well, shaking is normal with cars, but there is a shaking that can be terrifying, which you need to be worried about. Your safety and the safety of other drivers on the road are questionable if your vehicle’s braking structure is having problems.

Why Does My Car Vibrate When Braking at High Speed

The experience of an unusually vibrating vehicle, particularly when braking at high speeds, is a pain to many car owners, and that is why immediate action is needed. And, while there are many causes of vehicle vibration when you are braking at high speeds, for example, bad roads, it is an issue that needs immediate attention when the problem is originating from within the car.

This article will show you why you have been having that experience and what you can do to stop it. Therefore, let’s see.

Dry, Worn-Out and Unbalanced Tires

When was the last time you inspected your car wheels? Vehicle shuddering could be a result of dry, worn-out, and unbalanced tires. Most people will take care of every part of their car well except the tires. It is the tires that come into direct contact with the surface, and when they are dry, worn-out, or unbalanced, they can cause the vehicle to shudder excessively.

Moreover, tires” exposure to many negative impacts make them last for a shorter time. Make sure you constantly check your tires. Wheels are not circular. This is because the metal used to make them can be thinner or thicker in some parts, and this imbalance can result in vibrations, especially when driving at high speed.

Solution

To solve the issue of dry and worn-out tires, you need to buy new ones. When you take your car for maintenance, ensure they are checked. On the other hand, unbalanced car tires can lead to an accident, so they should be a worry to every driver.

Therefore, to solve the problem, you need to get them balanced by a mechanic, or you can do it yourself. Only ensure you have a wrench, a jack, and a screwdriver with a flat end if you decide to balance the wheels yourself.

Uneven Brake Rotors

Vehicle shaking when braking at high speed? Maybe there is an issue with the brake rotors. Also, the brake caliper can be the source of shaking. When there is an issue with the brakes, you will feel vibrations from the steering wheel, increasing the faster you move.

Wear and tear can make the brake rotors uneven. When the calipers and brake pads press these uneven rotors, they cause an uneven grip, which leads to shaking. If you have been feeling vibrations when you use the brakes, maybe it is time to check if there is an issue.

Solution

If your vehicle’s brakes are worn out, the best remedy would be to replace them with new ones. So you may need to take the car to a specialist who will fix the problem.

Bent Axles

Have you ever seen bent axles? This may not be a common problem, but it causes also lead to vigorous shakings when you are accelerating. The bent axles can be a result of mishaps and collisions. Therefore, it is important to check the axles too to be sure they are in perfect condition.

Solution

Front-wheel drive vehicles require new axles in case the original ones get bent. Make sure also your mechanic inspects the driveshaft.

Power Steering Issues

Have you been experiencing vibrations when driving on the road with many turns? If yes is the answer, there is a problem in the power steering structure. To ascertain if this is the cause of vibrations when braking, open the trunk and inspect the hoses. They could be leaking. Additionally, the steering fluids in the power engine may require topping off.

Solution

If you can identify leaking hoses, get them replaced. If there is a problem with the steering fluids and you don’t know how to fix this, get it sorted by a specialist. In case the transmission fluid is low, fill it up to the required level.

Worn Out Motor Mounts

Motor mounts are engine parts responsible for balancing your vehicle. The motor mounts keep your vehicle secure. Normally, they comprise of rubber and metal and are located between the engine and the car frame. Engine vibrations are absorbed by the rubber while the motor mounts get structure from the metal.

Over time, the rubber wears out, meaning it can no longer absorb engine vibrations, which results in a shaky car. On the other hand, worn-out metal cannot give a strong brace, and this, too, causes shakings when braking.

Solution

Vehicles can run with worn out motors. However, the shaky experience is not joyful, so you may need to replace the motor mounts. If the tremor is too much, you can have a professional inspect the motor mounts and fix them.

The Car Engine

The engine is the basic part of any vehicle, and a small issue can lead to more serious problems. Therefore it is good to inspect it when you start experiencing vibrations at high speed. Failure of the engine to receive enough requirements can be the reason it is not working well.

Solution

Buy new spark plugs and air filters to replace the old. In case the issue is not fixed, your car may have a serious problem that requires a specialist.

Sticking Brake Calipers

Brake calipers can cause a vehicle to shake. However, it is easy to solve brake caliper issues because most of the time, when you take your car to your mechanic for brake maintenance, they inspect the calipers. For cars covering many kilometers regularly, brake caliper monitoring is crucial. If you could take your car for servicing according to the manufacturer’s instructions, so many problems would be solved before they escalate.

Often, when your car’s oil is changed, the tires and brake pads are inspected. However, these regular inspections are not a must for cars traveling shorter distances; only in six months is it necessary. But for cars traveling long distances, the checks need to be contacted monthly.

Solution

Sticking brake calipers need to be replaced. One worn out rear or front brake pad is a sign of sticking brake calipers.

Dirty Brake Pads

Dirt, oil, and other contaminants can make the brake pads cause the vehicle to shake. The vibration is felt from the steering wheel. Dirty brake pads can be identified by a sharp noise when braking at high speed.

Solution

Always clean the brake pads. When they start to produce a sharp noise when braking, replace them because this can cause more serious issues like component suspension and the wearing of tires.

Alignment Problems

To test whether your car has alignment hitches, take it to a traffic-free horizontal highway and drive at 60 mph. Get your hands off the wheel for a minute and observe whether the vehicle will go left or right. If that is exactly how the car behaves, your car has alignment issues that are making it to vibrate.

Solution

You need to fix car alignment issues. It may require four-wheel or two-wheel alignment, which you can tell by checking the entire car. Cases that require four-wheel alignment are: when the car frame or the axle is damaged.

Spark Plugs

Spark plugs form a very vital part of a vehicle. They are responsible for controlling the oil function, and as other car parts, they too can be the reason your car is vibrating when braking. The first thing you will need to do is to find where the plugs are located. Usually, these are found at the tip of the engine. However, in several cars, other parts cover the plugs, and you cannot see the spark plugs until you remove the overlaying parts.

Once you identify the location of these spark plugs, remove them. To do this, you will need to ensure the vehicle is not heated up because the plugs can be hot. The ideal time to remove the plugs is when the vehicle has been idle. Underside the engine; there is a wire you need to pull to get your eyes on the spark plug. Make sure you do not disturb the lead in the process. After removing the plugs, measure their space to get their measurement. 

Solution

Once you have the exact measurement of your car’s spark plugs, buy new ones for replacement. You can install them by yourself or contact a mechanic to help you do it. If you choose to be your mechanic, get a spark plug socket and dismantle the old plugs and install the new ones. Be careful not to over tighten the plugs when installing them.

Blocked Transmission Filter

Once your vehicle has covered 20000 miles or has lasted two years, it is necessary to change the transmission filter. It can cause the vehicle to shake when it is blocked.

Solution

If blocked transmission filters are the reason your vehicle is vibrating, you can fix it. However, it is a process. Because you need to get under the car, jack it up. This makes it secure and safe for you to do all the tasks required underneath.

After that, get a transmission drainer and place it under the transmission filters to remove the fluid. A socket wrench is needed for the task. Afterward, remove the gasket seals and bolts to clean the pan then replace the old gasket seals and the filters with new ones. To dismantle the old filters, remove their bolts.

Worn Suspension Parts

Worn suspension parts are another cause of vehicle vibration when braking at high speed. Over time, wear and tear make suspension parts like tie rods, ball joints, and wheel bearings unfit for the car. If your vehicle vibrates when turning the suspension, it is likely to be the culprit. Mistakes caused by drivers like hitting potholes bend the rim, which causes the vehicle to tremble at high speed.

Solution

To solve the problem, take your car to a specialist for proper inspection. In case the rim is bend, replace it because it can lead to low tire pressure. 

Inadequate Transmission Fluid

Vehicle shaking is determined by transmission fluid. When the fluid is inadequate, you can expect vibrations when braking.

Solution

To solve the problem mentioned above, you need to add transmission fluid. To do this, you need to make sure the engine is idle. Normally, drivers add transmission fluids while the vehicle is running. Ensure you lock the hand brakes for safety.

You may have to consult your car dealer for the right type of transmission fluid to buy because transmission fluids come in various types. Moreover, once you have the correct fluid, it is important to read the instructions given so that you can add the correct amount. After that, connect a funnel to the transmission then pour the fluid.

A funnel is necessary to avoid overfills. Once done, check the fluid level to ascertain it is on max then run the transmission after depressing the brakes. This ensures you have the correct reading. Get back the dipstick into its position and lock it. By this time, the shaking problem will have ceased.

Final Words

It is important to follow the manufacturer’s instructions on car service. If only you would take the car for maintenance as required, you will not experience most of the car shaking causes discussed above. However, if you find yourself experiencing a shaky car, you can easily identify the problem and solve it as discussed.

Always make sure you contact a specialist in cases you feel they are out of your control to avoid damaging the car while trying to solve a problem you are not certain where it is coming from. Motor specialists know so many things you may not be aware of, so getting assistance from them is important. This way, you will solve the problem of a shaky car when braking at high speed.
