Do You Need to Bleed Brakes When Changing Pads?

You’ve probably seen the signs at auto parts stores and at service stations, but you don’t always know what they mean. Sometimes, bleeding brakes can seem a little scary.

Brake fluid is scary and can be dangerous, even fatal if it gets on the skin or in the eyes. This blog will look at what you need to know about do you need to bleed brakes when changing pads.

What are Bleed Brakes?

Bleed brakes in most cases mean that the brake fluid needs to be replaced. This can occur due to old brake fluid or after replacing the brake pads where the old and new pad material are not compatible.

So, Do You Need to Bleed Brakes When Changing Pads?

This is a very common question and many mechanics advise you that do you need to bleed brakes when changing pads.

You don’t need to bleed the system in regular situations. If you replace the pads, then you should drive the vehicle around for a few miles so air from inside of the brake system can bleed out, and then you should check the system for air bubbles with a brake bleeder.

However, if the pads have worn down excessively, then you should definitely bleed the brakes to get rid of air bubbles. So my suggestion is, if you have time and patience, don’t bleed the brakes. If you are in a hurry, then bleed the brakes.

Why Do You Need to Bleed Brakes in Certain Times?

Brake pads and brake rotors need to be in good condition to be able to do their job. Brake pads are made of a material that wears out over time but can last for 60,000 miles or more if they are not overheated.

When you change your brake pads, it is important to bleed the brakes afterward because air bubbles may have been introduced into the system during installation.

How Do You Bleed the Brakes?

Bleeding brake is a simple process. You can do it yourself or take your car to a mechanic. The method is different depending on the type of your vehicle.

  • After checking the reservoir on your car, jack up the car and put it on jack stands.
  • Next, remove the wheel and then loosen the caliper by spreading it a little.
  • Use a flat head driver to push the piston back in the caliper.
  • Now put rags on the caliper to catch any fluid that comes out.
  • Then loosen the hose from the caliper and put the hose on a container.

When Do You Need to Bleed Your Brakes?

Bleeding brakes is one of the most common tasks in a car workshop. If you take your car to a repair garage, they will tell you that you need to bleed the brake system every two to three years.

This is a standard service, and many mechanics will even do it free of charge. However, you can bleed the brakes of your own car, provided that you are confident enough about your abilities and have the right tools.


Changing pads without bleeding brakes is not recommended. It can cause brake malfunction and lead to accidents.
