Losing brake fluid & have no brakes unless I pump them

96 ford windstar van I have been told to replace the master cylinder. But I am not sold. Now I have brakes not even half the can pump them and have them & sometimes they will work just fine for A little bit. I am having to add brake fluid but have not noticed any bad leaks. To me it sounds like wherever the brake fluid is going out air is coming in and keeping the lines from being bled. It could be a wheel cylinder, master cylinder, cap or gasket on the master cylinder or a tiny hole in the brake line.I just dont have the time and money to buy new parts & it not be fixed.So mechanics saying replace the master cylinder without even seeing it or hereing any more than brakes go to the floor does not sell me .Please help!!

Quick tests to do to see if your master cyl is nackerd.

pull the valve on the brake buster out ( the 1 with rubber hose attached, and be gentle so as not to brake it)
check for moisture/ brake fluid on the valve. if there is mosture you will need a new master cyl.

you can also undo the master cyl from the booster and gently slide it forward and see if there is any fluid behind it and on the back off it if there is fluid you will need a new master cyl

good luck these checks are very easy and you should be ok to perform them

Brake lines probably broke. brakes stopped working suddenly.

There are many things other than brake lines that can cause braking loss. Investigation will reveal the issue. First, check fluid level in the Master Cylinder. If the level is normal, you don't have any broken lines/leaks. If the fluid is full and you have no brake pedal/braking power, chances are the Master Cylinder itself has failed. There are o-rings internal to the M/C that can fail, and when this happens, you will lose pressure to wheel cylinders/calipers and, as a result, lose your brakes.

If the fluid has leaked out, then you need to find out fro where. This is not too difficult normally. Fill the M/C with fluid and have someone press the brake pedal while observing the underside of the vehicle. You should see fluid dripping from somewhere, often near one of the wheels. You can have a leaking caliper/wheel cylinder, brake hose, or metal brake line. Once you determine what part has failed, you can purchase and replace the defective part. Brake calipers, wheel cylinders, and hoses are fairly simple to replace. Brake lines are more difficult, as they require shaping, cutting, and the creation of couplings. After repairs are done, the brake system must be refilled and all air bled from the system or braking will not be satisfactory.

2001 ford windstar lx master cylinder new i replaced but abs n brake light come on

Needs to have code reset for abs by a obd2 code reader with abs or find a parts house or shop that will reset it. Brake light coming on did you bleed the master cylinder out by connecting rubber lines to ths plastic insert ******* then acuating the master cylinder til all air is pumped out of master cylinder if that was not done then you will need to bleed all brakes until air is out of system that should turn brake light off

Ford van brakes go "soft"

The master cylinder probably needs new seals and the brakes need bleeding. First try replacing the brake fluid and doing a good bleed. If that does not solve the problem, go for the master cylinder.

Brake light staying on. on my 2001 ford windstar what might it be

check your master cylinderr fluid level. If full brakes may be worn badly or master cyoinder may be going bad.. if brakes are ok change brake sending unit usually located on master cylinder. do noty drive until you are positive your brakes are good. if fluid level is low in master look for brake fluid under car usually on back of wheel.if no brake fluid on back of wheel inspect brake lines for a hole usually rusted through. if this is helpful please leave me positive feedback.

Brake fluid leaking from master cylinder area after replacing front brakes on my 2002 Ford Windstar. I added 12 fl ozs of brake fluid to the reservoir after puttiing in new pads and rotors. Any idea if...

if you didnt remove any fluid from the master before you pushed the pistons back into the calipers ill bet it just leaked out then. clean it up and keep an eye on it for a while.

My Ford windstar 2001 cruise control just stop working. it has 107,000 miles. Also, when driving the van sputters, it seem like the brake is being applied but continues to move.

is there brake fluid leaking on the wires under the master brake cylinder? if so you need to call ford about the recall. Its also suspected that this problem causes a malfunction in the abs system.
you can look up your recall info here

My 1998 ford windstar abs brake light is on. In the past I had to add brake fluid and in doing so the light went out. I tried that but it continues to burn. Can it be reset?

thats odd. Adding brake fluid shouldn't have kicked on the ABS light..

Low brake fluid would cause your RED parking brake light to come on not the orange ABS light (unless thats what you mean. if thats the case its normal for that light to come on with low fluid. in this case check the brake lines starting to the master cylinder and the components at the wheels to make sure there is no leaks if you go HERE complained about your situation and also noticed a leak on the bottom of the master cylinder (hazardous in more than 1 way) )

not sure of the component locations under the hood of the windstar but check to see if you were bumping wires on the ABS control module when you were putting brake fluid in. may be a loose connection that jiggles loose when you drive.

otherwise it might need a new ABS control module or maybe moisture in one of the components.

My air, odometer, speedometer all went out at the same time. is that a fuse?

I just had this trouble. Fuse F-10 will be blown. It is caused by a short in the ABS deactivation switch which is on the front and bottom of the master brake cylinder under the hood. The master brake cylinder is on the drivers side under the hood and is the unit where you add brake fluid. It has a connector with 2 wires on it and when it leaks brake fluid, the 2 wires short out and blow the F10 fuse causing your problem. So check that switch on the bottom front of the master brake cylinder and replace it if you have been losing brake fluid. It fixed my problem.

Brakes fail.

You have a major brake fluid leak. The master cylinder, brake calipers, hose, steel lines or rear wheels cylinders are leaking. Not safe to drive until you repair it.

Bleeding brakes

No need to run the engine. Start the bleed procedure from the caliper farthest from the master cylinder, and work toward it. This means bleed the passenger rear first, then the driver rear, then passenger front, then driver front. Don't stop bleeding any caliper until you get three or so consecutive streams of air-free fluid through the bleeder. Monitor the level of fluid in the cylinder, and be sure the cap is on while bleeding - only open it to add additional fluid as needed.
