New Brakes Not Stopping Well – The Potential Danger

Many drivers often think that only the old brake stops poorly, taking a long time. However, this is a completely wrong thought because new brakes not stopping well are uncommon.

So what is the reason? What sign to write this?

Let us help you answer these questions.

Why Do New Brakes Not Stopping Well?

New Brakes Not Stopping Well

There are two main causes – damaged brake pads and brake fluid, which make your new brakes not stop well. Particularly, what are they? We’ll tell you the details below.

Worn Brake Pads And Discs

After a long time of use, car brakes will be worn away. Brake pad wear results in its surface not making contact or having limited contact with the disc’s smooth surface.

It reduces the frictional force and makes it difficult for the car to stop.

Similarly, the contact surface of its disc will also wear out due to the amount of dirt, dust, and impurities on the road surface splashing on this part.

Old Or Low Brake Fluid

Brake fluid has completely different physical properties, so its main role is transmission.

Due to the incompressible nature of the liquid, it can transmit the impact force from the brake pedal to other parts of the system in the most accurate way.

This power transfer function requires it to have a fairly high viscosity.

One thing to remember is to check the oil level after a certain period of use to ensure the correct oil level.

As the brake pads wear, the oil in the master cylinder reservoir drops. But when they are good, indicating that the system is open somewhere.

Oil line connections or terminals are often the most sensitive. Also, check for leaks at the end of the master cylinder.

If oil appears in the sealing ring, it is necessary to replace the master cylinder, but before that, check and repair the leak in the pipeline.

Several other causes can also lead to this error, such as air entering the oil line, wheel hubs being too dirty, the master cylinder having too much oil, etc.

How To Break-In Brake Rotors And Brand New Brake Pads? 

This is a high-temperature and friction process. Its purpose is to coat the rotor surface with an even layer of pad material. It would help if you did this properly unless you want the system to overheat.

After you install the widget, follow the instructions below:

  • Drive to a wide, empty area and park in a safe place.
  • Pump the brake to see if the pedal is firm.
  • Drive carefully to ensure the new brake system works properly—test performance, vibration, metallic sound, etc.
  • Continue driving for a long distance in that area and apply the brakes for 3 seconds after 0.5 miles.
  • Be patient and repeat the operation 30 more times. Don’t forget to use light, medium, and starting speeds.
  • It is normal to feel the pedal force and pedal stroke increase. They will disappear after cooling the system.
  • Finally, drive a few more miles and try not to slam on the brakes (unless it’s dangerous) to cool them.

When To Check The Car Brake System?

New brakes not stopping fast enough is possible. That’s why you need to pay close attention to them while driving.

Be careful with the following signs and quickly take your car to reputable centers for timely car brake maintenance:

  • The brake light is always on: The cause of this condition may be a faulty handbrake switch, a low or damaged fluid level sensor, or information from the wear sensor.
  • Brakes not eating: The cause of this sign can be a fault in the piping, pads that are too hard or too soft, uneven wear, etc.
  • Hard brake: Caused by high working frequency, piston jam, no periodic maintenance, improper maintenance, or using the wrong type of grease for a long time.
  • Grinding sounds: Unusual car noises are the clearest sign that something is broken. The cause here may be due to worn pads leading to a squeaking sound every time you press it.

Other signs include the vehicle rolling to one side, the car turning, undulating, shaking, pedals close to the floor, uneven pads worn, cracked oil pipes, fluid pressure, brake lines, etc.

How Much Does Pad Replacement Cost?

Brake pads are one of those automotive parts with unimaginable speeds and rates of wear and tear. If you’re a “brake” driver, you must keep an eye on this.

The cost of replacing pads is unknown, and not everyone is interested. Each car repair garage has a different price.

Many factors can affect the replacement cost, but it depends mainly on the price of the pads your vehicle needs. Installation and maintenance time does not take up much because it is fast and simple.

Since this is a basic part of a car, you will have many options, but it only has 2 main types: details from the car manufacturer and parts from OEM (Original Equipment Manufacturer).

The price of the models also depends on the model of the car. High-value cars, less popular cars, often have a higher price.

For normal car colors, this cost will range from 100 to 300 dollars for each disc brake pad shaft.

In addition, because some models have a wear sensor when installing, you should remember to adjust the wear clearance gap.

What To Do To Protect Brake Pads After Replacing?

When this system fails, the driver will not have the opportunity to correct his mistake while driving because it can lead to unfortunate accidents.

However, no matter how well it is checked and maintained, it cannot always work properly.

In addition to regularly checking the overall car brakes to promptly detect abnormal signs, bad habits in the process are also the cause of the quality deterioration of this system.

The first common habit that easily damages this part is that many car owners often return to P, turn off the engine, and pull the handbrake.

The long-term will adversely affect the life and durability of the gears inside the gearbox.

Many people also habitually strongly grip them when going downhill or down a pass.

This is extremely dangerous because it can cause the brakes to friction, generate great heat, cause a fire, or even cause the vehicle to lose its brakes.

According to professional mechanics’ advice, when going downhill, let’s follow the principle of upshifting and downshifting to reduce the normal pressure on this system.

Don’t forget to change the fresh fluid periodically to maintain power.


Above is information about the problem of new brakes not stopping well. Even the new ones may not work the way you think they should.

To avoid encountering unfortunate mistakes, you should check and maintain this part carefully.
