The right rear wheel is usually the best place to start because it's the furthest from the master cylinder. Loosen the bleeder valve/screw and place a small piece of rubber hose over it. Make sure it's about a foot and a half to two feet long and fits over the bleeder snugly. Place the loose end into a large (quart) container of brake fluid, all the way to the bottom. Start pressing the brake pedal. This allows the air to come out and bubble to the top of the container without sucking air back into the system. You can try it on the furthest wheel away and work your way to the front. Tighten the bleeder before removing the hose.

Why not?

If you have the engine running,a helper,
and crack open the bleeder, as your
helper pushes lightly on the brake,
and no one pumps the brakes ever,
for any reason,your all set

Just close the bleeder before the pedal
get to the floor and repeat 10 to 14 time

You need to "bleed" the brake lines... HAve someone in the car pump the brake 3-4 times and hold the peddle to the floor. Crack the bleeder screw once this procedure is done, retighten the screw and then re-pump the brake peddle 3-4 times and on and one IN THIS ORDER until you feel that the air is no longer in the new brake lines. Make you that you keep enough brake fluid in the resivour otherwise you will be starting your process over.

Brakes went out


Have you checked the master cylinder for leaks and around the brake booster? You may have a bad brake light switch.

brakes can be a pain to fig out. first thing that pops in my mind is air in your lines. your van has ABS on it, you have to bleed your brakes a certain way. what im thanking is air in the ABS pump. alot of cars, you bleed your brakes RIGHT FRONT then LEFT REAR then LEFT FRONT then RIGHT REAR with ABS also the set up you are using to bleed your brakes if you dont use it right it will let air back in to your system. make shur your calpers arnt leaking

i hope this helps if not just let me know and i can give you some more tips

The problem is not the booster, the job of the booster is to make braking easier. If the booster went out the brakes would be hard to press.
Your soft pedal is likely due to air in the brake lines. Bleed the brakes and go from there.

Brake pedal goes to floor i have already changed mastercylinder and bleed brakes no waring lights are coming on new brake have been installed


sounds like air in the line. Did you start your bleed at the right rear.If you replaced the M/C you have air in the line.Get a helper and pump the brakes until all of the air is out , starting at right rear.It may take a few tries to get all the air out , but with new everything it is this or a leak. Was the master C. new or rebuilt. Check all 4 wheels for any sign of a leak. If no leaks and you bleed all the air out maybe your master cylinder is bad.

How to fix broken brake oil hose attached to the wheel brake


If the hose is a flexible hose, you simply replace it with a new one. If a steel tube, then a replacement will need to be made up. You local better brakes will be able to do this for you as they have the tube and the double flaring tool.

Newly installed brake rotors and pads. balanced wheels, but still shakes when brakes are applied. I can also feel the shaking on the steering wheel when driving on rough road.


Apply the emergency brake slightly while driving to see if the rear brakes are the issue. Other wise the rotors are warped or there is debris behind the rotor to hub surface

Changing 4 calipers and there is no oil com out when try to bleed


The master cylinder supplies the pressure to the brake fluid that travels between the maste brake cylinder resevoir and the brake caliper pistons (through the brake lines. If the master cylinder fails there will be insufficient compression of the brake fluid to make the calipers operate as designed. Leaks in the brake lines and/or cylinders is a possibility, and unrelated to functionality of the master cylinder. Also, pistons located in the brake calipers can form a corrosion ring on their inside walls if there is breakdown in the brake fluid or moisture that gets into the lines. Operating the vehicle when there is insufficient brake fluid in the master cylinder resevoir can also lead to air getting into the brake lines, causing bad working brakes. Air compresses more than brake fluid, and the master cylinder isn't designed to compress air in the brake lines. Sounds like a bad case of "lack of maintenance", as opposed to bad advice from the mechanics. That said, there's no excuse for bad installation. But, it's tough to improperly install a brake line since they are nothing more than hollow metal tubes. There should be no rubber connectors installed in the brake lines. When bleeding the brake lines one must remove all of the trapped air before you will see any fluid appear. If the valves in the master cylinder are not properly operating the master cylinder will not allow the brake fluid to get into the brake lines.

Hope this helps.
