Remember to have a helper with you during the brake bleeding process. They should apply full brake pedal pressure when you instruct them to do so and release the pedal only when commanded. This will help ensure a proper brake bleeding procedure.
Before moving on to the next wheel, top off the brake fluid reservoir. It’s recommended to check the reservoir and refill it before bleeding each wheel. If you are replacing all the old brake fluid, you may need to go back to the first wheel and start the process again.

Why does order matter when bleeding brakes?

The sequence matters. If you have a lot of air right after your master cylinder for whatever reason, that air can travel to any point in the system. At some point, the hydraulic line attached to the master cylinder will branch to each of the four wheels.

How does the factory bleed brakes?

A vacuum is drawn through the master cylinder, which removes air from the entire brake system. Then while the equipment is still sealed to the master cylinder reservoir, internal valves simultaneously close off the suction pump and allow pressurized brake fluid into the brake system.

How do you bleed GM ABS brakes?

To bleed the isolation valves in the modulator, there are two bleeder screws. Start with the one toward the engine. Turn the ignition on and apply light pressure on the brake pedal. Open the bleeder screw and allow the fluid to flow until clear.

How do you bleed brakes with ABS by yourself?

In general, whenever you are bleeding an ABS-equipped vehicle you can do so exactly as you would any other vehicle – stroke the pedal to pressurize the system, open a bleeder, close the same bleeder, and repeat. This does not change whether you are pressure-bleeding, vacuum-bleeding, or manual-bleeding.

Do you bleed brakes with reservoir cap on or off?

Locate your brake master cylinder reservoir’s brake fluid level, usually located under-the-hood. Ensure that your car has the appropriate amount of fluid. While you’re bleeding the brakes, you’ll want to be sure that you leave the master cylinder cap unscrewed but rest it on top of the reservoir.

Why are my brakes still spongy after bleeding?

A spongy brake lever, or a brake lever which has to be pulled a long way before you feel the brake start to work, is a sure sign of air trapped in the brake system. Some brakes can be more troublesome to bleed than others. Even after multiple bleeds air can remain trapped inside the caliper.

What is the correct brake bleeding sequence?

What happens if you don’t bleed brakes in order?

The pistons require a certain amount of hydraulic pressure to clamp the pads against the rotor. If air bubbles are in the system, the reduced hydraulic pressure makes it harder for the pads to grab the rotors. While uncommon, you could damage the master cylinder if you don’t bleed the brakes correctly.
