When drivers apply the brakes, they may notice a jerking sensation in the vehicle. There are a number possible explanations for this, but the most prevalent ones are that you just installed new brake pads or that your old ones are severely worn.

As a rule of thumb, cars that jerk when braking are usually the result of a problem with the braking system, especially if the replacement of the discs or drums was done incorrectly or with poor quality parts. Because of this, jerks begin when a cast iron disc is held in place by the steel base of the brake pads when they are worn down.

The steering wheel can also be struck by other causes of car jerking. When you use the brake, your automobile jerks, and we’ll explain why.
Bent brake discs
Many times when you drive and tap the brake repeatedly, the discs will be hot and on the road you will go to the vehicle wash or encounter a puddle with cold water. This is when the discs will bend.
Due to the quick drop in the brake disc temperature, if the brake disc material is of poor quality, the possibilities of it changing its form are extremely high.
If your brake discs aren’t at least 20 millimeters thick, it’s time to get a new set.
This problem can be solved in two ways. It’s possible to straighten the brake discs in a specialized auto shop by following the instructions in the video below. Just swapping over the old discs with new ones made of high-quality material would be a far better option.

As part of the brake disc replacement, you’ll need to replace the brake pads as well.
Change in the geometry of drum brakes
Deformed drum brakes can be caused by abrupt cooling, just like deformed disc brakes. Drum brakes should be replaced with new ones.
The brake discs are installed wrong
Incorrectly placed brake discs can produce friction between the pad and the rotor, which can damage the rotor. This needs to be addressed as quickly as possible.
Worn brake pads
Cars might jerk as they come to a stop because of worn brake pads. The squeaks, which are metal antennae that rub against the discs, generating a squeak and thereby warning the car owner that it is time to change the brake pads, are another symptom of brake pad degradation.
Changing the brake pads with high-quality ones is the only answer to this problem.
Sticking brake pads
Not only is it uncommon for the brake pads to be the culprit, but when this problem did arise, it resulted in the car jerking both when stopping and driving. It’s time to inspect the brake pads and their calipers. In most circumstances, the brake pads need to be replaced.
Calipers are worn
Cars with a lot of miles or inadequate maintenance are more likely to have this problem. As time goes on, the calipers will wear out and become loose. Changing the calipers would be the only option in this situation. After installing new parts, grease them.
Differences between the hardness of the brake discs and the pads

In this case, you’ll need to replace the discs with softer ones and install new brake pads. So, you need to be careful when choosing the right brake discs.
Damaged bushings
Rear suspension bushings are referred to in this context. When the brakes are worn, the car will jerk.
Wheel bearing play
When braking, the wheels, particularly the front wheels, will tremble as a result of this problem. Wheel bearing replacement is the best option.
Rust on the brake discs
For those who haven’t driven in a while, you may have noticed that the brake discs begin to corrode. Those who live in humid climates should take note.
If you don’t drive your automobile for a lengthy period of time, you’ll end up damaging it. If you do this, the rust coating will remain consistent, necessitating the more costly approach of replacing the discs instead. The solution shown in the video above is an option, but it is not advised.
For the first 12 to 18 miles of driving, the rust layer will dissolve spontaneously. When you brake, the automobile will jolt as a result of this.
Air in the braking system
Having air in the braking system results in less efficient braking, which might cause jerks when you apply the brakes. Air must be drained from the system, and braking fuel must be added.
Conclusion
When you apply the brakes, your vehicle may jolt for a variety of reasons. To find out what’s causing the problem, you’ll need to do a series of tests in a car shop equipped with the proper tools. You can’t figure it out by observing because it’s commonly associated with brake disc and brake pad issues. This problem is more than simply a nuisance; it may be a serious threat on the road.
