All people are conscious of their driving because the driving schools teach the ABC of driving. The driver should master this before they get the license and get into the real world. Here B represents the brakes in the car. It is necessary to brake whenever needed so that accidents can be avoided. The person should know how much break to apply based on the situation. Sometimes a little force is enough, but at other times, hard braking is required. But in the process did your car make a clunking noise from the rear when braking?
We all know that materials wear out when in contact for a long time. Brakes also wear out over time. The person can notice clunking noises when braking, which insists on changing the parts. If your car is making such noises, read this article to learn what causes them and how to fix them.

How Do Brakes Work?
Nowadays, the brakes are operated under hydraulics, where the fluid acts as the medium. When the pedal is pressed, the fluid transmits the pressure to the brake system, which arrests the motion, respectively. The brake oil should be refilled or replaced from time to time for effective performance.
The parts of the brakes can wear out over time because the materials get in contact every time. Many parts of the car work in contact with other materials, like brakes. So, it might eventually wear out over time. It might cause squeaky clunking noise when braking. So, It is better to replace the worn-out and damaged parts to avoid system failure, which could end worse in some cases.
What Causes Clunking Noise When Braking?
The person can hear grinding noises while braking, which is the symptom that some parts have been worn out. It is better to inspect the issues and replace or repair them to avoid failures. If the person ignores such problems, they could propagate, and it might even get worse. The failure or damage in the system could cause loud clunking noise when braking, and if you hear it, then this must be the cause of it.
1. Loose Bolts
The brakes are connected with joints, and the system is connected to the wheels through bolts. If any of the bolts are loose and not fixed properly, then it damages the brakes and wheel when braking. The loose bolts will allow the wheel to wobble and hit the brake system sometimes, which might cause clunking noise while braking. Tightening the bolts or replacing them, if necessary, will arrest the noise.
2. Loose Calipers
The brake callipers suspend near the wheel allowing the brake pads to touch the rotor when the pedal is pressed. This contact slows the wheel, and thereby the vehicle stops. If the brake calliper is loose or hanging, then the brake pads barely touch the rotor and strike with the wheel. It might also be the reason for the clunking noise. Tighten the callipers and make sure it doesn’t get loose again to arrest the noises.
3. Bad CV Joints
The constant velocity joints can be found in every vehicle. The inner joint connects the transmission to the axle, and the outer joint connects the axle to the wheel. Generally, a car has two CV joints, one for the front wheels, and another for the rear wheels. A damaged CV joint is prone to dust and dirt that affects its function. It could affect the joints and gears in the CV joints. If the CV joint is not working correctly, it might make noises when stressed. Sometimes, the person can hear a clunking noise when braking.
4. Damages Suspension
The suspension system is attached to the wheels to support the vehicle. A flawed or damaged suspension could also affect the function of the brakes and makes noise. One of the parts of the suspension system includes shock absorbers, also called dampers, which are attached near the wheels for support. If the shock absorber or the spring is damaged, it might make a rear knocking noise when braking. There are many reasons for the suspension to fail, which cannot be discussed in this article. Check our article on suspension failures to learn more bout it.
5. Damaged Axle
An axle is a rod that transfers the power to the wheels, and if it is damaged, it could affect the function. A damaged axle affects power transmission, and the effect directly impacts the driving. Sometimes, a damaged axle might also make noises under pressure and stress, and at worse, it could break. The car could never move with a broken axle or a driveshaft. The entire system has to be replaced in this case to resolve the issue.
6. Bad Brake Pad
A lousy brake pad might lead to brake failure, which always ends badly. It is attached near the rotor and gets in contact when the pedal is pressed. The brake pad gets in touch with the rotor to arrest its rotation and stop the wheel from moving. Also, the contact will wear out the material over some time. If it is not aligned correctly, then it might make noises when it hits nearby parts. The brake pads must be replaced regularly for effective performance.
These are some common reasons for clunking noises when braking, and some repairs and replacements can also resolve it if you have any such noises when braking, then check it and solve it immediately. Because driving with a bad brake is not only dangerous to you but also to the others who are driving on the road.
Frequently Asked Questions-
So, here are some of the frequently asked questions about the Causes, how is clunking noise diagnosed, can bad brakes make a clunking noise, can tie rod end cause clunking etc?-
What Can Cause A Clunking Noise When Driving?
When a clunking noise is produced then it can be due to the followimg reasons?-
- First, it can be due to Bad control arm bushings.
- Loose callipers
- Worn out struts.
- Damaged Axle
- Damaged leaf spring shackles.
- Bad brake pad
How Is Clunking Noise Diagnosed?
A clunking noise is diagnosed by-
- Inspect your shocks and struts.
- Inspect your upper control arms for the cause of clunking noises while you are driving.
- Inspect your inner tie rod ends
- Inspect your power steering rack.
- And also Inspect your lower ball joints.
Is It Safe To Drive A Car With Clunking Noise?
No, it is not safe to drive a car with clunking noise as it can put passengers at risk. In this situation, you should consult your local mechanic.
Why Does My Car Clunk When I Slow Down?
Car slunk when you slow down due to faulty steering stabilizer, wheel bearings, shocks etc.
Can Bad Brakes Make A Clunking Noise?
When brakes are Clunking this is due to wear and tear or worn-out brake pads.
Can Tie Rod End Cause Clunking?
A clunking sound from the front of the vehicle when it is at low speeds can be a problem of bad tie rods. When they become loose, tie rods at the joints and links, causing the new noises you will hear.
Brakes play an essential role in the safety of the people inside the vehicle. Any brake failures might result in an accident, and it is only the skill of the driver that saves them. But, every system exhibits specific symptoms to alert the issue so that it can be resolved. It is the person’s responsibility to inspect and replace the parts to avoid further problems. Next time you hear any noise in the brakes, then check the system and resolve it immediately.
