Caliper Functions
Brakes rely on the calipers to apply force to your brake pads. Calipers are often called the “pads” on your vehicle’s brakes because they’re responsible for pressing your brake pads against your rotors (and sometimes even other parts). If a caliper is loose, you’ll need to fix that before you ever start driving with it loose, or if it already started causing problems, then more serious problems might be looming.
What Is a Loose Brake Caliper?
A loose brake caliper is part of a vehicle’s braking system that can cause severe damage if it is not properly maintained. It is an important component of the disc brakes, and its purpose is to secure the brake pads against the spinning rotor to allow for efficient braking.
A loose brake caliper typically occurs when the mounting bolts or pins become loose or corroded, causing them to no longer hold the caliper in place properly.
This can lead to excessive vibration, reduced vehicle stability, and increased wear on other parts of the braking system due to improper alignment. The risk of a loose caliper increases with age as well as from road salt or dirt entering into the components leading to rust and corrosion.
Signs of a Loose Caliper
A loose caliper might cause problems like:
- Unusually high brake temperatures
- Brakes that feel very soft, almost to the point of not working
- Strange noises when braking
- Slipping when braking
You should always be aware of odd changes in the way your brakes feel or function. You should be especially concerned if you started feeling or noticing any of these symptoms after an incident that could have caused damage to the calipers. Accidents and road debris impact are the most common causes of this kind of damage.
Loose brake caliper bolt symptoms
Loose brake caliper bolt symptoms can include:
- A loud grinding sound when braking
- Decreased braking performance
- Increased stopping distances
- Soft or spongy feeling on the brake pedal
- Vibrations in the steering wheel
- Brake rattling
If left unchecked, a loose caliper bolt can cause premature wear to the vehicle’s brakes, causing reduced braking efficiency and potentially leading to an unsafe situation.
Other problems might cause some of these symptoms. Not all of them have to point to a problem with the calipers. However, you should always get a professional mechanic’s opinion before driving with a loose caliper.
What Causes a Caliper Loosen
Several factors can impact the tightness of brake calipers. Here are the most common causes:
Issues with the braking system
The most common cause of a caliper loosening is improper installation or over-tightening of the mounting bolts. This can lead to an imbalance in the system, causing the caliper to vibrate and eventually become loose.
Negligence and lack of proper maintenance, like not replacing brake pads in time or not getting regular inspections done on time or at all. If your brakes are damaged due to negligence, you should look into your car insurance policy to see what kind of coverage you have for this kind of damage.
Wear & tear
Other causes include corrosion of the bolts and fasteners due to weather conditions, lack of maintenance, and wear and tear on the caliper itself over time.
Road debris
Road debris, such as gravel and stones, can also damage the caliper’s components, leading to looseness. Many said this is the most common cause.
Other factors
Finally, suppose a vehicle has been in an accident or experienced sudden jolts or shocks during its drive. In that case, this can also cause the caliper to loosen due to unexpected shifts in forces.
Can You Drive With Loose Caliper?
Of course, the answer is NO! If you drive with a loose caliper, you are at risk of damaging your brakes and possibly your whole vehicle.
If they are loose, not secured in place with the correct hardware, or even if they are secured but are not working properly, they’re very likely to cause problems. If you’re already in an accident due to a loose caliper, you’ll have more problems at fault that will affect your auto insurance premium.
Don’t gamble on being able to drive with a loose caliper.
For example, I was on a freeway in Texas in the summer of 2019 and witnessed an accident related to a loose caliper.
While driving at highway speed, the driver’s front left caliper came loose, causing intense vibrations and wobbling from the wheel. The driver quickly noticed what was happening and began to slow down as they pulled onto the shoulder.
Fortunately, the driver managed to stop without incident, but had they not noticed or been able to react quickly enough, the resulting crash could have been fatal.
How To Fix Loose Calipers
Your vehicle owner’s manual should have instructions on how to fix loose calipers. You should not have this kind of trouble if you regularly get your brakes checked for any signs of problems.
Here is how you can tighten it up:
Tools You Will Need:
- Jack
- Wheel chocks or stands
- Brake caliper bolt torque wrench (recommend #10)
- 10mm socket wrench for your wheel bolts
- Double-check your other duties while your car is in the air or on jack, stands, e.g. while the car is in the air, have someone watch your other duties while you do this.
How To Tighten Up Loose Calipers
Make sure your car is on jack stands or parallel to the ground. Brake dust can be very hazardous if inhaled while working with brakes. So, you should always wear a mask when working on them. You should also have a fume extractor in case you are not wearing a mask while working with brake dust inside your nose or mouth.
- Install the caliper retaining screw, and tighten it by hand until it is snug and loose. It’s important to ensure that the caliper is snug so that it will not be coming off during normal driving.
- Next, bolt on the calipers and tighten your wheel bolts securely with a torque wrench to ensure proper brake caliper torque.
What to Do if You Have a Loose Caliper on The Road
Items needed:
- A wrench or socket set
- Aerosol spray cleaner
- New nuts
If you have a loose caliper, the first step is to park your car in a safe location and make sure that the parking brake is engaged.
After that, you must locate the caliper and loosen its mounting bolts with a wrench or socket set.
Make sure to disconnect any brake lines connected to the caliper.
Next, remove the wheel bearing from its hub assembly with a puller tool.
Then, clean any dirt or debris around the bolt holes on the caliper bracket using compressed air or an aerosol spray cleaner designed for automotive use.
Once done, reinstall the wheel bearing and secure it with a new retaining clip or nut.
Finally, tighten the caliper bolts and reconnect any brake lines before testing your work by pressing on the brakes several times.
