Brakes Rattle When Hitting Bumps: Causes and Solutions

brakes rattle when hitting bumps

If you’re driving along and you hit a bump in the road, you might notice that your brakes start to rattle. Rattling is a common problem, and it’s usually nothing to worry about.

Let’s get through the details to know more about this issue.

Reasons to Rattle the Brakes when Hitting Bumps

  • Because of the structure, your brakes rattle when you hit a bump.
  • There are two main types of brakes – drum brakes and disc brakes. 
  • Drum brakes have a set of shoes that force against the inside of a rotating drum. 
  • Disc brakes have a bunch of pads that press against the surface of a rotating disc.
  • When you hit a bump, the force of the impact transmits through the suspension and into the brakes. 
  • Force can cause the shoes or pads to move slightly, which can cause them to rattle.
  • In most cases, this is nothing to worry about. 
  • Your brakes will still work fine, and the rattling will stop as soon as you release the brake pedal.
  • However, if the rattling is severe, or if it doesn’t stop when you release the brake pedal, it could be a sign of a more severe problem. 
  • It’s always a perfect idea to have your brakes checked by a qualified mechanic if you’re concerned about them.

Steps to Follow to Fix your Brakes that Rattle when Hitting the Bumps 

  • One possibility is that the brake pads are loose. 
  • To check this, look at the places and see if they are open in the caliper. 
  • If they are, then you will need to tighten them.
  • Another possibility is that the brake caliper is loose. 
  • To check the brake caliper, hold it with one hand and try to wiggle it with the other. 
  • If it is open, then it will need to be tightened.
  • If neither of these is the problem, the rotors may be under the warping condition. 
  • Warping can happen if the brakes get too hot. 
  • To fix this issue, you must change the rotors with new ones.
  • Hopefully, one of these solutions will fix your rattling brakes.

FAQs of Rattle Brakes when Hitting Bumps

What are the consequences of ignoring a brake that rattles when you hit bumps?

  • When you hear a brake rattle, it’s essential to take notice and take action. 
  • Ignoring the problem can have consequences ranging from decreased braking power to complete brake failure.
  • Brake pads are designed to press against the brake rotors to create friction that slows the wheels. 
  • When the brake pads are worn down, they can rattle against the rotor. 
  • Warn-down brake pads can cause the rotor to warp, decreasing your braking power. 
  • In extreme cases, the brake pads can detach entirely from the caliper, causing complete brake failure.
  • If you notice your brake rattling, you must take it to a mechanic to check it out. 
  • Brakes are one of a vehicle’s most critical safety features, so it’s better to be safe than sorry.

How often should you check your brakes for rattling?

  • There’s no definitive answer, but it’s generally a good idea to check your brakes every few months. 
  • Of course, if you’re hearing rattling sounds from your brakes, it’s probably time to take them in for a check-up sooner rather than later.
  • So if you’re hearing rattling sounds from your brakes, don’t ignore them. 
  • Get them checked as soon as possible.
