Question about 2003 Suzuki Aerio

Brake bleeding causes loss of vaccum

Was bleeding brakes on my 2003 suzuki aerio sx. Lifed all four tires off found the brake bleeder valve. Each had a cap on it. As my friend pushed down on the brakes, i went to each one and loosened the nipple to get air bubbles out, and before he lift up the brake peddle, closed off the nipple. All the while doing this, making sure the brake master cylinder was keeping plenty of brake fluid as to not allow any air to enter the lines. Eventually, I bled all the bubbles out and all that was coming out was a solid stream of brake fluid. This is how I bled brake fluid on all my much older cars, but when I did this Suzuki this way, it was all worse than when I started. I then tried the exact same process with the car idling and turned on, thinking that some pump must push the fluid. Same results. I have to press the peddle many times then press down or it feels super mushy and the brake pedal hits the floor. Please help.

Brake pedal goes all the way down to the floor after I bleed all four wheels. Did I get all the air out of the line or is it something else?


Did this problem occur after the bleeding procedure or was the bleeding procedure performed to correct this issue? There should be no air in the system unless a brake line was changed/opened or the master cylinder was empty. Sounds as if the master cylinder is defective.

Cant get breaks on my 2002 blazer ather break lane breaks


After you fix a brake line, you need to bleed the line. There is air in the line that needs to be bleed out of the line. Make sure the vehicle is not running, totally shut off. First - find which tire the brake line goes to that you just fixed. Two - then have someone in the vehicle pumping the brake three times, then on the third time, have them hold the brake to floor. Three - open the bleeder valve on the brake caliper of the tire that the brake line goes to.(Note - You need the tire off the vehicle to do this.) Four - once the the bleeder valve is opened, and all the brake fluid, and air comes out, close the bleeder valve and repeat the whole process several more time. Each time you bleed the brake line you are releasing the air in the line, and creating pressure with just fluid in the line. Usually three to four tries of bleeding the line will solve the air in the brake line problem and your brake pedal will become hard.

Proportioning valve 1988 f350


The reason is, you have a rear anti lock brake system. The anti lock valve is located on the frame just underneath the brake master. It is called a RABS valve. Almost impossible to bleed. But it can be done. A dealer has a tool that plugs into the RABS valve which activates the valve constantly moving the valve back and forth. This will then push all fluid and air out of your open bleeder screws in the rear.
I did'nt go to the dealer. i was too stubborn. My solution was to lift the rear of the truck and place on jack stands. Pinch off the rubber brake hoses on the 2 front brakes with a C-clamp or non marring vise grips, this will keep all fluid from going to front brakes. Next adjust the rear brake shoes by tightening the adjuster on the rear brake drums. Tighten the brakes on the rear until the brakes start to drag and the tires no longer spin freely by hand. Attach a bleeder hose to the bleeder screw on the RABS valve, place open end of hose into a jar or canister of brake fluid, so as not to draw in any air. Open the bleeder screw. Start the vehicle up, put it in gear, and let the rear tires spin. (I got up to 25mph on my speedometer) Step on the brake while it is in gear and the tires are spinning. This will activate the RABS valve and cause the air in the RABS valve to bleed. Do this several times. Put vehicle in park, shut off engine, and close the bleeder on the RABS valve. Attach bleeder hose to right rear of the truck, place open end of hose in a canister or jar of brake fluid so no air gets in and open the bleeder screw. Start the vehicle up, put it in gear, and let the rear wheels spin freely. As the wheels spin, you press your foot on the brake pedal, this will activate the RABS valve, and effectively bleed the brakes. Do this a dozen or so times, tighten the bleeder screw and do the other side. Remove clamps from front brake hoses and you will be go to go. All this may seem a bit extreme, but it is the only effective way to bleed a Rear Anti Lock Brake System on an early Ford. All the steps I laid out are necessary. You cannot skip one. The reason why the rear has to be in the air, is that there is a sensor mounted to the rear differential that senses wheel spin(or axle spin), this goes directly to the RABS valve and tells it that the tires are moving at a certain speed, and to activate the Rear Anti Lock Brakes when the brake pedal is depressed. It will not activate if it does not sense movement. The reason for pinching off the front brake lines, is that there are needle valves in the master cylinder and they will send too much fluid to the front calipers, and stifle or hinder the amount of fluid needed to go to the rabs valve and ultimately the rear wheel cylinders. It seems like a lot, and it is, but I did it and it works. Good luck

How do you bleed the brake system on 2003 suzki grand yitara 4x4 with abs brakes


The hydraulic brake system must be bled any time one of the brake lines is disconnected or air enters the system. There are two ways to bleed the system; pressure bleeding or manual bleeding. Both procedures will be given here, although pressure bleeding requires the use of some fairly expensive equipment (a pressure tank) and is seldom used. Both methods are equally effective.The correct bleeding sequence is: left front, right front, left rear, and right rear. On master cylinders equipped with a bleeder valve, bleed the master cylinder last.
PRESSURE BLEEDING
  1. Clean the top of the master cylinder, remove the cover, and attach the pressure bleeding adapter.
  2. The spring-loaded plunger on the front of the proportioning valve must be depressed while bleeding. Wire or tape can be wrapped around the valve to hold the plunger in.
  3. Check the pressure bleeder reservoir for correct pressure 20-29 psi (137-206 kPa) and fluid level, then open the release valve.
  4. Fasten a bleeder hose to the wheel cylinder or caliper bleeder nipple and submerge the free end of the hose in a transparent receptacle. The receptacle should contain enough brake fluid to cover the open end of the hose.
  5. Open the wheel cylinder or caliper bleeder nipple and allow the fluid to flow until all bubbles disappear and an uncontaminated flow exists.
  6. Close the nipple, remove the bleeder hose and repeat the procedure on the other wheel cylinders according to the sequence.


MANUAL BLEEDING(see Figures 1, 2 and 3)An alternative to the pressure method of bleeding requires two people to perform; one to depress the brake pedal and the other to open the bleeder nipples.
  1. Clean the top of the master cylinder, and then remove the cover and fill the reservoir with clean brake fluid.
  2. To prevent squirting fluid replace the cover.
  3. The spring-loaded plunger on the front of the proportioning valve must be depressed while bleeding. Wire or tape can be wrapped around the valve to hold the plunger in.
  4. Install a box end wrench on the left front bleeder screw.
  5. Attach a length of small diameter, clear vinyl tubing to the bleeder screw. Submerge the other end of the rubber tubing in a glass jar partially filled with clean brake fluid. Make sure the rubber tube fits on the bleeder screw snugly or you may be squirted with brake fluid when the bleeder screw is opened.
  6. Have your friend slowly depress the brake pedal. As this is done, open the bleeder screw half a turn and allow the fluid to run through the tube. Close the bleeder screw, then return the brake pedal to its fully released position.
  7. Repeat this procedure until no bubbles appear in the jar. Refill the master cylinder.
  8. Frequently check the master cylinder level during this procedure. If the reservoir runs dry, air will enter the system and the bleeding will have to be repeated.

Hope helps.

    I need to bleed all the fluid out of my brake lines. i put trans fluid in for break fluid accidently. how do i go about the bleeding?


    if you haven't driven it yet you might still be able to save it but if ATFgot into your seals you might end up having to replace all your braking components.you have to open the bleeders at all four wheels and let it all just drain out. you might want to go barrow a brake bleeder set from advance auto parts they have loaner tools for free.once its all out refill.goodluck

    Sounds like your brake light switch, located on the brake pedal, has gone out. Shouldn't cost too much more than $20 to get a new part and about 30 min. to fix. Good luck and thanks for using FixYa!

    Start from right rear, then, left rear, right front, left front. Fill master cylinder. Have helper sit in car, have helper hold brake pedal down. open bleed screw. fluid and air comes out. close screw. release brake pedal. Continue until no air comes out. Move to next wheel. Keep an eye on master cylinder fluid level after each wheel.
