How Does a Brake Flush Work

A brake flush is a service that your car’s technician provides when it’s time for your brake pads or discs to be replaced. Essentially, the technician uses a special tool to clean out any debris and oils that may have built up over time in the brake system. By doing this, they ensure that the brakes will work properly and respond quickly when you need them to.

How a Brake Flush Works

Brake fluid is used to help the brakes operate more smoothly and effectively. When the brakes are applied, the fluid travels through the brake system and out the back of the brake pads. This action causes a rotating force against the rotor, which helps to stop the vehicle.

Brake flushes happen when the brake pads need to be replaced, and the old brake fluid is removed. The mechanic will use a tool to remove all of the old brake fluid from around the brake rotors. Next, they will fill up the new brake pads with fresh brake fluid and replace the cover on the brake caliper. Finally, they will reattach all of the necessary components, including the Brake Flush Tool.

This simple procedure helps to keep your brakes in good condition and ensures that they will perform as expected when you need them to.

When to Perform a Brake Flush

A brake flush is a great way to keep your brakes in good working order. Here’s how it works:

1. Park your car in a safe location.
2. Remove the wheel covers.
3. Locate and loosen the brake calipers (see photo). The pads should be able to move freely in the caliper bracket. If they are not, use a pry bar or screwdriver to remove the caliper (photo).
4. Pour brake fluid into each caliper. Make sure to get all of the fluid inside the caliper (photo).
5. Replace the calipers and tighten the bolts to 75 ft-lbs (103 Nm). Torque values will vary depending on make and model of car; consult your owner’s manual for more information.
6. Return your wheel covers and drive away!

How Often to Perform a Brake Flush

Brake flushes are a routine maintenance procedure that your car should undergo at least once a year. Brake flushes remove the old brake fluid and debris from your brake system, ensuring efficient braking performance. In most cases, you should perform a flush when your brakes start making noise or when the fluid looks dirty. Here’s how it works:

1) Park your car in a safe location with the parking brake on.

2) Remove the cap on the brake fluid reservoir.

3) Pour fresh brake fluid into the reservoir until it is full. Don’t overfill it!

4) Replace the cap on the reservoir, and reinstall the brake lines.

5) Start your car and let it run until the brakes stop working properly. When they do, you’ve completed the flush!

What to Do if the Brake Flush Does Not Work

If your car’s brake flush does not work, there are a few things that you can try. First, make sure that the brake fluid level is correct. Next, check to see if the hose connecting the flush valve and the master cylinder is kinked or obstructed. If it is, straighten it out and try the flush again. Finally, check to see if the brake pedal feels spongy or if there is any resistance when you push it down. If any of these things are true, your brake system may be damaged and you will need to replace it.


Brake flush is a process used by mechanics to eliminate the build-up of brake dust and debris on the brake system. It is usually done when there is an indication that the brakes are no longer performing at their peak potential.

This procedure involves flushing all of the fluid lines in the braking system, from each wheel to the master cylinder – essentially cleaning everything out so that it can be re-used more efficiently. By doing this, you ensure that your car will stop as quickly and as safely as possible should any problems arise with your brakes.
