New Brakes Making Rubbing Noise; Why?

New Brakes Making Rubbing Noise; Why?

A quick overview of the issue and the fixing; If your new brakes are making a rubbing noise, it could be because the brake pads are not properly seated in the brake caliper. This can be caused by improper installation or by the pads being of the wrong size.

To check this, make sure the pads are properly aligned in the calliper and that the calliper is properly tightened. If the noise persists, it may be necessary to replace the pads with a different size. Additionally, you should inspect the rotors for any signs of damage or warping, as this could also be causing the noise.

In this article, you’ll find why your new brakes making rubbing noise, and the ways to fix it with all the relevant information you need to know. So stick around until the end to find out what you’ve been looking for.

What are the possible causes for the new brake pads to make a rubbing noise?

The most common cause of a rubbing noise when using new brake pads is a misaligned caliper. This can occur due to an improperly installed caliper, an uneven surface on the rotor, or the caliper having been shifted during installation. 

Other possible causes for a rubbing noise include a worn out brake rotor, a sticking caliper, or a loose caliper bracket. In some cases, the rubbing noise may also be due to a contaminated brake pad, a brake pad that is too thick, or a pad that is not properly seated. 

Additionally, the noise may be caused by debris or a foreign object trapped in the brake pad. To identify the underlying cause of the noise, it is important to inspect the brake assembly, check the caliper alignment and clearance, and replace any worn or damaged components.

Brake pads are too tight

If your brake pads are too tight, you may need to adjust the brake calipers. You can do this by loosening the mounting bolts and sliding the caliper back until it is in the proper position. 

You can then tighten the bolts and check the pads to ensure they are not too tight. If the pads are still too tight, you may need to replace them with new ones.

Contaminated brake rotors

Contaminated brake rotors can cause serious problems with braking performance. If the rotors are contaminated, it is important to take the necessary steps to clean them. 

This can be done by removing the rotors, cleaning them with a degreaser or brake cleaner, and then sanding them down with fine-grit sandpaper. 

Once the rotors have been cleaned and sanded, they should be reinstalled and the brakes should be tested to make sure they are functioning properly.

Brake calipers are not centered

If your brake calipers are not centered, it could be an indication of a problem with the brakes. It could be an issue with the brake pads, the brake calipers, or the brake lines. If the calipers are not centered, you should have them inspected by a professional mechanic to identify the cause and determine the best course of action.

The most important brake pad related hardware is the caliper bolts and slides. Caliper bolts and slides are responsible for keeping the brake pads in place, and if they are loose or worn, the brake pads may not be held in the correct position, or they may become loose and start to rattle and make noise. It is important to check these components regularly and replace them if they are worn or loose.

How to Fix Grinding Brakes on Your Car (Rotors)?

Why my new brakes make grinding noise at low speed?

Brake dust, dirt, or rust on the brake pads and rotors is likely the most frequent cause of noisy brakes, especially at low speeds. The road’s surface debris, mud, water, and dirt are constantly in contact with brake pads, rotors, and calipers.

New Brakes Making Rubbing Noise

There are several steps that can be taken to avoid problems with brake pads. 

  • Firstly, make sure the brakes are regularly serviced and inspected for damage or wear. 
  • Secondly, replace any worn brake pads as soon as possible to ensure the brakes are working properly. 
  • Thirdly, remember to keep the brakes clean and free of debris. Finally, if possible, use higher quality brake pads which are more durable and provide better stopping power. 

All of these steps can help to reduce the risk of problems with the brake pads and help to keep the brakes in good condition.

Why are my brakes grinding after new rotors?

The most likely cause of brakes grinding after new rotors are installed is that the rotors are not properly machined. When rotors are machined, their surfaces must be perfectly flat and parallel in order for the brake pads to make full contact with the rotor surface.

 If the rotors are not machined properly, the brake pads will not make full contact with the rotor, resulting in uneven brake pad wear, vibrations, and grinding noises. 

Additionally, if the new rotors are not perfectly concentric, meaning that the rotor is perfectly round, the brake pads will not make even contact with the rotor, resulting in uneven wear and grinding. To avoid this, always make sure to use quality rotors and have them machined to the manufacturer’s specifications.

Is it normal for brakes to make noise after replacing?

Yes, it is normal for brakes to make noise after they have been replaced. The noise is usually caused by the brake pads settling into the caliper and rotor, as well as air bubbles being released as the brake system is being bled. The noise should subside after a few days of driving.

As already mentioned, new pads are frequently abrasive and occasionally coated with noise-generating protective materials. That brake pad squeak will disappear after some wear, also known as a “bedding process.”

Is it safe to Drive when brake pads make noise?

No, it is not safe to drive when brake pads make noise. The noise indicates that the  brake pads are worn and need to be replaced. 

Driving with worn brake pads can lead to reduced stopping power and an increased risk of an accident.

How do you break in new front brakes?

After giving the brakes some time to cool, the vehicle should be aggressively slowed down eight to ten times from 60 mph to 15 mph. Before using the brakes once more, the car should sit for a while or be driven slowly on an empty road to allow the brakes to cool.

What happens if you don’t break in new rotors?

Reduced braking power, uneven braking power, noisy brakes, and a shorter pad lifespan, though not usually the rotors, are all effects of failing to bed in a rotor. The majority of these effects are long-term, though making them permanent might be going too far.

Can you damage brakes by braking hard?

Yes, you can damage brakes by braking hard. Brake pads, rotors, or other components can wear down and need to be replaced if brakes are used too aggressively.
