Pick the proper wrench or socket that fits the spiral, and loosen the screw.

Special wrenches called bleeder wrenches fit the bleeder screw and can prevent rounding the screw's hex-head. Be conscientious not to pause the screw off or you'll need professional repairs. If it's stuck, spray some penetrant like WD-40 effectually the spiral. Later on you loosen the screw, tighten information technology again (merely non likewise tight).

Place a pocket-sized slice of flexible hose over the cease of the bleeder screw and place the other end of the hose in the jar.

Then fill the jar with brake fluid to comprehend the end of the hose. If y'all don't have anything that fits over the bleeder screw, simply go on the jar near the nozzle so that any fluid that squirts out lands in the jar.

Brake fluid volition squirt out (duck!). If there's air in your restriction lines, air bubbles will be in the fluid. Seeing these bubbles is easiest if you're using the hose-in-the-jar method, but you lot tin also see them without it.

Before your friend releases the brake pedal, tighten the bleeder screw.

If you don't, air is sucked back into the brake lines when the pedal is released.

If that happens, you take to become dorsum and bleed your master cylinder until you suck the air out of that terminate of the system. Who needs the extra work?

If you goof and have to bleed the chief cylinder , it's the aforementioned deal equally bleeding your brakes (friend and all). Just bleed information technology at the point where the brake lines adhere to the cylinder or at the master cylinder's bleeder nozzle if it has one.

Repeat this process with each brake until the air is out of each brake line.

Don't forget to add brake fluid to the master cylinder later yous bleed each restriction.

After you bring the restriction fluid level in the master cylinder back to the "Full" level for the terminal fourth dimension, drive the vehicle effectually the block.

The brake pedal should no longer feel spongy when you lot press it. If it does, check the master cylinder once more to be sure that it's full, and try bleeding the brakes one more time. This situation isn't unusual, and it doesn't accept as long equally information technology sounds.
