Single Pop Noise When Braking: What Causes It and How to Fix it
What causes that single pop noise when braking? It’s the same noise you hear when you’re driving over a bump in the road. This can be caused by air bubbles getting into your brake fluid due to heat exposure, or it could be caused by an internal leak.
If either of these is happening, then it will need to be fixed as soon as possible to avoid any safety issues with your brakes. In this blog post, we will discuss what causes a single pop noise and how to fix it!

What is a Single Pop Noise When Braking?
When you hear a single pop noise when braking, it can be concerning. It’s important to understand the source of this noise so that you can address it properly. The most likely reason is that your brake pads are worn out. Over time, the brake pads will wear down and eventually need to be replaced. When this happens, you may start to hear a squeak or pop noise when you brake. The squeaking and popping is the sound of your pads rubbing against your rotors as they wear down, similar to how a pencil makes noise on a piece of paper.
Why do I hear a popping sound when I brake?
Single pops can also be caused by other factors such as:
- Worn out rotor hardware
When a car’s rotor hardware is worn out, it can cause a popping noise when the brakes are applied. This is because the bolts that hold the brake disc in place can become loose and start to rattle. If you’re experiencing this problem, it’s important to have the rotor hardware replaced as soon as possible.
- Rotor warp
A rotor warp is another possible cause of a popping noise when braking. This occurs when the brake disc becomes bent or warped, and can usually be identified by a pulsing feeling in the brake pedal.
- Loose or worn out brake pads
Loose or worn-out brake pads can also cause a popping noise when braking. This is because the pads can start to move around and come into contact with the rotor.
- Improperly adjusted brakes
If your car’s brakes are not properly adjusted, this can cause the vehicle to shake when braking. The shaking causes the brake pads to come into contact with the rotor – a process that produces a single pop sound.
- Frozen or contaminated brake fluid
Brake fluid can also be contaminated by water if the brake lines are not leak-proof or are old, cracked, or corroded. This can cause one of the most common reasons for a single pop sound when braking. When the brake fluid is contaminated, it can cause the brake pads and rotor to freeze.
- Foreign objects caught in the brakes
If there are any foreign objects caught in the brakes (e.g., leaves, twigs, nuts, bolts), this can also cause a popping noise when braking. This happens because as the object rubs against the brake pads and rotor, it creates friction which produces noise.
- Brake caliper sticking
If the brake caliper is sticking, this can also cause a popping noise when braking. This happens because as the brake pedal is pressed, the caliper doesn’t move freely and rubs against the rotor.
If you are experiencing a popping sound when braking, it is important to take your vehicle in for inspection by a qualified technician as soon as possible.
Signs You Need New Brake Pads or Your Brake Fluid Changed
There are a few key signs that you need new brake pads or to change your brake fluid.
One sign is if you hear grinding noise when you hit the brakes. Another sign is if your car pulls to one side when braking. If your brake pedal feels soft or spongy, that’s another indication that something might be wrong.
If you notice that your car is taking longer to stop than usual, your brake pads might be worn out.
How to Maintain Your Brakes Properly With Simple Maintenance Techniques?
You should measure the thickness of your old brakes before deciding which new ones to put on your car. If you have more than 0.12 inches of pad left, then you can safely wait until it is time for a complete brake replacement job. On the other hand, if you have less than 0.12 inches of pad material remaining on your brakes, then it’s time for a new set of pads.
The brake service checklist:
- Check brake fluid level
- Inspect hoses and lines for damage or leakage
- Test brakes for proper function
- Measure brake pad thickness
- Inspect discs for damage, warping, or cracks
- Inspect calipers and drums for leaks or sticking
- Inspect master cylinder and vacuum assist booster for leaks
- Check the brake pad wear sensor function
- Inspect wheel cylinders for leaks, sticking, or damaged pistons
Check the level and condition of your brake fluid every time you change your oil or every other time you have your car serviced, whichever comes first. Low levels could indicate a leak in the system that requires immediate attention.
How often should I change my Brake Fluid?
You can find the manual of instructions for specific make and models on this website if you’re unsure about how frequently to change it. But typically, brake fluid should be changed every two years or 24,000 miles.
Please keep in mind that these are just general guidelines – always consult your vehicle’s owner’s manual to get the most accurate and up-to-date information about maintaining your car.
Clicking sound when pressing brake pedal
If the clicking sound is accompanied by a vibration in the brake pedal when driving, it may mean that there is something wrong with either the front or rear brakes of the vehicle. It could also indicate faulty rotors on wheels or problems within the ABS braking system such as air bubbles in fluid lines.
Popping noise when braking and turning
One of the reasons to hear popping noise when braking and turning could be because the piston is not traveling deep enough into the caliper before hitting its stopping point.
Another reason could be because there are air bubbles in the brake fluid which cause a rattling noise when it is pushed through the system by the pistons moving back and forth. If you have recently filled up your brakes then that can also cause popping noises due to pockets of air being caught inside of the brake lines or calipers themselves.
