Please Read Entire Description below for important notices and disclaimer!

Be sure your vehicle is properly lifted and supported before beginning this procedure. ! -use your repair manual for this information.

Step one: Top off the brake fluid.

Step two: Gravity bleed the brakes at the wheel you are trying to remove air from. "Gravity bleeding" is basically just letting the brake fluid drip with the reservoir cap off and the bleeder screw open. Once a drip has been achieved proceed to step three.

Step three: After the bleeder screw has been closed and the brake fluid topped back off and the reservoir cap has been installed have an assistant pump the brakes for you three times and hold it applying constant pressure on the pedal. While pressure is being applied to the pedal open the bleeder screw slowly. Allow air and fluid to escape until the brake pedal has reached the floor. Once the pedal has reached the floor then close the bleeder screw..... Repeat this step repeatedly until you get a constant flow of brake fluid. If you see spitting then that means their is air. CHECK YOUR BRAKE FLUID REPEATEDLY ESPECIALLY IF YOU ARE BLEEDING FOR A LONG TIME. TOP OFF AS NEEDED.

Step four: Once all the air has been removed tighten down the bleeder screw to the specification outlined in your repair manual and check the feel of the brake pedal. The pedal should be nice and firm and should not fade to the floor when applying pressure. If the pedal is not firm then air may still be present in the system. Remove all the air from the brake system before driving vehicle.

It's been my experience that the majority of vehicles are to be bleed at the right rear first, then the left rear, then the right front, then the left front.

Please note: If the system has ingested too much air and air could not be fully removed from the brake system the ABS HCU may have to be bleed using a bleeding procedure that requires special tools such as a scan tool that is capable of this etc. Also, If the master cylinder was replaced the master cylinder must be bench bled in order to removed air from it. (not shown in video)

If you are not successful in removing all the air from the brake system and are not able to achieve a consistently firm and responsive brake pedal DO NOT DRIVE THE VEHICLE TO A SHOP. TOW IT TO A SHOP TO HAVE IT REPAIRED. DRIVING YOUR VEHICLE WITHOUT PROPERLY WORKING BRAKES IS DANGEROUS AND COULD RESULT IN PERSONAL INJURY AND OR DEATH TO YOU AND OTHERS!

!!Notice!!: Do clean any residual brake fluid that may have gotten on your caliper or other components when bleeding your brakes. Brake fluid is corrosive and can possibly promote rust. Make efforts not to get brake fluid on wheels or tires. Brake fluid can be slung off the wheels and tires. This can possibly get onto your paint. Brake fluid can eat through your paint.

Note: the vehicle shown in the video was not running at the time of bleeding the system. Unless your repair manual states other wise I suggest having the engine off when bleeding the brakes.
Also, this procedure may not apply to every vehicle out there. Use a repair manual to confirm what is the correct way to bleed the brakes on the vehicle you are working on.
