Tip & How-To about Ford F-150

Brake bleeding procedure (step by step)

Required tools and supplies:

Box-end wrench suitable for your car's bleeder screws.
(An offset head design usually works best)
Extra brake fluid (about 1 pint if you are just bleeding)
(3 if you are completely replacing the fluid)
12-inch long section of clear plastic tubing (sized to fit snugly over your car's bleeder screws)
Disposable bottle for waste fluid.
Brake cleaner.
One assistant
(to pump the brake pedal).

1. Open the hood and check the level of the brake fluid reservoir.

2.Add fluid as necessary to ensure that the level is at the MAX marking of the reservoir.

3.Do not let the reservoir become empty at any time during the bleeding process.

4. Begin at the corner furthest from the driver and proceed in order toward the driver.
(Right rear, left rear, right front, left front.)

This will also allow the system to be bled in such a way as to minimize the amount of potential
cross-contamination between the new and old fluid.

5. Locate the bleeder screw at the rear of the caliper body (or drum brake wheel cylinder.) (Remove the rubber cap from the bleeder screw)
6. Place the box-end wrench over the bleeder screw. An offset wrench works best since it allows the most room for movement.
7. Place one end of the clear plastic hose over the nipple of the bleeder screw.
8. Place the other end of the hose into the disposable bottle.
9. Place the bottle for waste fluid on top of the caliper body or drum assembly.
(Hold the bottle with one hand and grasp the wrench with the other hand)

10. Instruct the assistant to "apply." The assistant should pump the brake pedal three times,
hold the pedal down firmly, and respond with "applied." Instruct the assistant not to release
the brakes until told to do so.

11. Loosen the bleeder screw with a brief ¼ turn to release fluid into the waste line.
The screw only needs to be open for one second or less. (The brake pedal will "fall" to the floor
as the bleeder screw is opened. Instruct the assistant in advance not to release the brakes
until instructed to do so.)

12. Close the bleeder screw by tightening it gently.
13. Instruct the assistant to "release" the brakes. Note: do NOT release the brake pedal while
the bleeder screw is open, as this will **** air back into the system!

14. The assistant should respond with "released."
15. Inspect the fluid within the waste line for air bubbles.
16. Continue the bleeding process until air bubbles are no longer present.
Be sure to check the brake fluid level in the reservoir after bleeding each wheel!
Add fluid as necessary to keep the level at the MAX marking. (Typically, one repeats
this process 5-10 times per wheel when doing a ‘standard' bleed.)

17. Move systematically toward the driver – right rear, left rear, right front, left front -
repeating the bleeding process at each corner. Be sure to keep a watchful eye on the brake
fluid reservior and Keep it full

18. When all four corners have been bled, spray with brake cleaner and wipe dry with a clean rag.
Try to avoid spraying the brake cleaner DIRECTLY on any parts made of rubber or plastic, as the cleaner
can make these parts brittle.

19. Test the brake pedal for a firm feel.
(Be sure to inspect the bleeder screws and other fittings for signs of leakage. Correct as necessary.)

20.Road Test.

how do I bleed the brakes on a 99 gs300

I am not familiar with Lexus, however braking systems are usually the same for all cars.
I first suggest purchasing a service repair manual for your vehicle that will give you step by step instructions. Also, I suggest calling a dealer (mechanic, or experienced Lexus mechanic to see is if this is a procedure that can be done at home). Some newer, "classy" cars are designed differently and require special tools and/or procedures for repairs such as this.
There are bleeder valves (zirk fittings) on the backside of the brake hub. It will require (usually) an 8 millimeter opened end wreng (line wrench if you have access to one); otherwise a regular open end will work.
Also, you will need a second person to pump the brakes; you loosen the bleeder valve until fluid comes out and no air. Do this for each side (front and back) until no air is released. In addition, make sure you have extra brake fluid, as you will need to make sure the resevoir is full when finished, and may need to add between bleeding each side.
Follow these instruction for each side, then take the car for a short drive (don't go too far from place of service; home, shop etc). Then bring it back and bleed the same way one more time.
If you have any questions, please let me know.

Bleeding the brakes on a 2005 saturn vue

I would start by removing the wheels and finding the bleed screw or bolt.
Pour a little brake fluid on the bolt to free up the rust that will form over time.
Then use a box end wrench to open the bleeder.

Fill the master cylinder with brake fluid and have some ready to add as you bleed the brakes.

Have an assistant push down on the brake pedal until it bottoms out and fluid squirts out of the bleeder screw area.

Watch your eyes.

Then tighten the bleeder screw.

Have them pump up the brakes again.

Do this in sequence from the furthest wheel from the master cylinder to the closest, and you'll be done.

How to bleed the brakes on the front wheels 1994 dodge caravan?

to do it in a back yard the process is simple, but it requires two people.
first make sure the brake fluid reservoir is full, then locate the bleeder valve on the brake caliper, its not always required to take the tire off, but be prepared to remove the wheel. The bleeder valve looks the same as a grease fitting, or a brass nipple, its also likely covered in road grime and brake dust

the tools you need are likely a 3/8, 1/2, or 7/16 open end box end wrench, or just a small cresent, just make sure its tight arount the box part of the fitting so you dont mess it up, its made of brass.

ok, so one person is inside the vehicle and another is holding a wrench on the bleeder valve, once you have everything ready losen up the bleeder valve so its easy to turn. Have the person inside the vehicle pump up the brakes until they are hard and keep pressure on the brake pedal, then slowly turn the bleeder valve until fluid starts comming out, then tighten it back up, so you dont let air back in. then repeat as nessesary, then do it one more time just to make sure, then tighten the valve all the way, and repeat the process on the next wheel

be careful not to loosen the nipple too much or you could end up with fluid in your face or eye, which sucks, so take your time and dont get in a hurry, you are gonna lose some fluid through the process so dont fret about it just make sure you have enough fluid to compensate for the loss, also make sure the bleeder valve/ nipple is tight when you are done or you just undid everything you were working on, plus you wont have any brakes when you go to stop

air in brake lines

If it's really air in the lines it will take two people to bleed it out, and if you're not careful you can make the problem even worse. You will need a bucket, a rag, and a small wrench (usually 3/8 or 7/16, and a box wrench works best). The lucky person needs to pump the brake pedal several times until the brakes are rock hard. Then the unlucky person needs to open the small bleeder valve of the back of a wheel (near where the brake line enters the wheel) and let the combination of air and brake fluid spray out - hopefully into the bucket. Once the pedal hits the floor, tighten the valve. Repeat this process two or three times on each wheel, or until the flow is all fluid - no air, making sure that the bleeder valve is retightened each time before the brake pedal is released. If the pedal is released with the valve open, air will be sucked into brake system, making the problem even worse. Oh yeah, the rag is for the brake fluid that misses the bucket and ends up all over the pavement and the guy working the bleeder valves.

Try using a pressure bleeder. It will force the air out. Works every time.
