Do You Have To Bleed Brakes After Changing Pads?

Bleeding the brakes to eliminate air bubbles is highly recommended to prevent spongy feelings and long periods of a stop. If you’re wondering do you have to bleed brakes after changing pads? Yes, because it helps to get rid of crud in the braking system.

In this article, we’ll be discussing this question in detail. Let’s get started.

How To Bleed Brakes After Changing Pads?

Bleeding brakes is a no-brainer task and this can be undertaken by anyone. But the task involving the change of brake pads might need the service of a professional. The purpose is to avoid damaging the brake master cylinder in the long run. Bleeding brakes after changing pads help to remove air bubbles in the lines and prevent the buildup of crud.

Below are steps for bleeding brakes after changing pads:

Step 1:- Locate The Bleed Valve

Most vehicles have a bleeder valve or screw for bleeding the brakes. It occurs at the bottom of the brake caliper assembly. Use your car manual to locate the bleed screw or valve.

Step 2:- Gather Necessary Tools

These vital tools are a flathead screwdriver for opening the bleeder valve, a pan for collecting used brake fluid, and a pressurized container for filling the brake system with new fluid. Drain the Used Fluid Remove the cap on the brake master cylinder and undo the bleed valve. Place the pan below and allow the used fluid to flow by gravity. You can also use a pressurized container to force the fluid out of the brake lines.

Step 3:- Refill The Brake System With New Fluid

Pour the new brake fluid into the master cylinder to the required level. Pushing the brake pedal enhances the distribution of fluid to the lines. Close the cap of the master cylinder and the bleeder valve by squeezing the calipers back after changing the pads.

Do You Have To Bleed Brakes After Changing Pads?

Yes, it helps to get rid of crud in the braking system. But this usually depends on how you deal with the system. Some people consider opening the bleeder valve and squeeze calipers to change the brake pads.

The brakes are the most underrated parts of a vehicle. These components help to halt a car and avoid road carnage since the system work by pushing pressurized fluids.

The brake fluid should be free from air bubbles throughout. The brake systems with air bubbles do experience less pressure that causes spongy-feeling and long stoppage time. It would be best to note that opening the bleeder valve on the brake increases the risk of damaging the master cylinder.

The best option is to hire a certified professional to undertake this task without ruining the brake master cylinder.

What Happens If You Don’t Bleed the Brake System?

The answer to your question do you have to bleed brakes after changing pads and what happens if you don’t bleed the brake system?

Bleeding the brake system with air bubbles is highly recommendable. Air bubbles are known for reducing hydraulic pressure and putting a damper on brake performance. Remember to exercise precautions when bleeding the brakes.

Is There A Need To Bleed All Four Brakes?

If you’re wondering do you have to bleed brakes after changing pads? Most vehicles have unique braking systems due to the technological dynamics in the automotive industry.

Ultimate care when bleeding the brakes is necessary to avoid further damage. So, do you need to bleed all four brakes? Yes. It is the best practice to bleed all four brakes after opening one brake line. But if the brake line is independent, there is no need to bleed all four brakes.

The rule of thumb is to identify the brake line of your vehicle and follow the appropriate brake bleeding procedure to fix them. Be sure not to mix incompatible brake fluid into the system.

How Much Do Mechanics Charge To Bleed Brakes?

1. Why Are My Brakes Still Spongy After Bleeding?

The possible causes are contaminated brake fluid, system leaks, and improper bleeding techniques. Remaining air bubbles between the brake lines could also be the potential reason behind the spongy feeling after bleeding the brakes. The best solution is to open the bleed nipple and push the caliper piston back into position. It helps to fit the brake pads in the appropriate position and allows the proper flow of air into the system.

2. Can I Bleed Brakes With Tires On?

Yes. But if you can reach the bleed valve without any challenge. If this is your first time bleeding the brakes, we recommend hiring a certified professional.

3. Do You Need To Bleed Brakes After Changing Calipers?

Not really. But if you have the three ABS systems on your vehicle, changing any of the front calipers will be ok to bleed brakes independently. Otherwise, there is no need to bleed the whole system out when changing one caliper. Be sure to use a pinch clamp to prevent the fluid from running out of the master cylinder.

We recommend hiring a certified technician to perform this service. Bleeding brakes after replacing calipers can be challenging for a single person.


Opening the brake lines may allow air to enter the system to cause some trouble. Bleeding the brakes after replacing brake pads helps to eliminate air bubbles from the fluid. It allows brakes to have normal pressure and perform their function well. Be sure to seek assistance from professional technicians.
