Step 1: Jack Up the Vehicle

Lift the car with a jack. Then, remove the wheels and tires. Notice if there is any dirt or debris at the junction of the brake line. If any, wipe them off with a clean cloth. Make sure the place is completely clean. Now, let the place dry.

Step 2: Locate the Bleeder Bolt

To find the bleeder bolt, you need to look at the end of the brake caliper. There you will see a long cylindrical plug that’s a bleeder bolt. Its main function is to relieve pressure inside the brake line.

Step 3: Unscrew the Bleeder Bolt and Clamp the Tube

Loosen the bleeder bolt using a wrench. Then, place the tube over the open mouth of the brake line and attach it to the bleeder with the help of the wrench. Keep the tube long enough to facilitate work.

Step 4: Apply the Brakes

Now tell your assistant to push the brake pedal of the car a few times. When he/she presses the brake pedal, you will notice that some fluid coming out of the brake line each time the pedal being pressed. 

Step 5: Rinse the Bleeder Bolt

At this stage, tell your assistant to stop pushing the brake pedal. Open the tube and clean the bleeder bolt thoroughly with a clean cloth. 

You can also use compressed air instead of cloth. Apply some lube around the area connecting the line to the car so that there is no problem later.

Step 6: Replace or Add New Brake Fluid

Since all the air has been removed from the brake line, now you have to add new brake fluid. Remove the cap from the master cylinder reservoir. 

Now add the brake fluid with the help of a funnel while holding the brake pedal. At this time there will be pressure in the reservoir. If there are any bubbles in the break line, then they will come out. 

However, make sure that the fluid does not rise above the level. When the fluid is added, remove the parking brake and wait a few minutes. 

Now the question may be how much fluid is needed. It depends on how much fluid you have flushed by pressing the paddle through the tubing. However, the amount should usually be about a quarter. 

There may be a leak where the brake line is attached to the vehicle. To test it, pour a little fluid in that place and wait for a while to test it.

Step 7: Tighten and Preserve the Bleeders

Tighten the bleed bolt using a wrench and with the help of your assistant keep checking to see if there are any bubbles in the brake line. 

When tightening, be careful that air from the brake line does not re-enter. Then, secure the brake line with a clutch-type clamp.

Step 8: Recite the Technique On Each Wheel

Apply the same process to the other wheels of the car in the same way that you have just got the air out of the brake line of one wheel. 

However, be concerned about damaged or old brake lines as the brakes may fail at certain times after removing air from them. 

This is even more dangerous on highways or busy roads. So you need to make sure that you can successfully remove all the bubbles.

Step 9: Refill the Brake Fluid Reservoir

Now check all the brake lines of your car again. Make sure there are no holes in the line for air to enter. Then, refill the reservoir with fluid.

Step 10: Do a Test Drive

Finally, you do a test drive. After driving, check to see if the cylinders are full of fluid. If you see any disturbance, such as air entering the line, repeat the above steps until you get the desired result.
