I have a Ford Windstar it has antilock, how I can do the bleeding; because I replaced the entire rear brakes the drums, the wheel cylinders, and replaced the front hoses. which side is where I have to start to do the job. I want to thank you in advanced.

the wheel cyliners need to be replaced ,that is most likely where it is leaking , recommend bleeding the brake system both front and rear after changing the rear wheel cylinders

The rear brake cylinders are located inside the hub with the brake shoes on drum brakes...(common in 2004 Rangers on rear only) The brake cylinders are a "wear item" with seals...we used to rebuild the cylinder with new seals...best today to buy new brake cylinders to replace the leakey ones...You will need to bleed all 4 brake line/wheel connections after the replacement. Hope this helps.

You should start on the most far wheel - typically it's rear right wheel, then rear left, then front right and front left.

your probably going to have to bleed the entire system.1st try & bleed the master cyl.
basicly the same as you would bleed the front/rear brakes. pump pedal & hold while someone
loosen the brake line on the master cyl. after m/c is bleed move to r/r,l/r,r/f,l/f wheels in
that order. if you have abs brakes & you got air in the pump a scan tool may be needed
to bleed properly.

Good question, on the antilock system is a bleader too and bleade it the same way you bleade the caliper. After all is done adjust the rear brakes, they should have a drag to them.

To trouble shoot the brake system you have to check:AntiLock Brake System ABS:
Hydraulic Modulator
Basically this unit holds steady or bleeds off pressure in brake line, as necessary, when the Electronic Brake Control Module (EBCM) detects an abnormal deceleration in the speed of the wheel. On 2000 and later models the EBCM and Brake Pressure Modulator Valve (BPMV) are mounted on a bracket attached on the left strut tower.

It sounds like the end has popped out of your wheel cylinder. You will have to take off the wheel, brake drum, and replace the wheel cylinder. It will then be necessary to bleed the entire brake system.If the brake shoes are soaked with brake fluid you will want to replace them. While the drum is off , double check that the wheel bearings are also OK.

the outer seals to the wheel cylinder are bad. Replace that item

Remove wheel, brake drum, and brake shoes. The cylinder is the part the brake line goes into and it spreads the brake shoes apart when you brake.

Loosen the brake line but do not take off, unbolt the cylinder and then disconnect brake line. loosely connect the brake line to the new cylinder so you do not loose much brake fluid, bolt new cylinder in and then tighten the brake line.
Reinstall shoes. There should be a bleeding screw/grease head in the brake cylinder, loosen this and have someone step on the brake to bleed the line, have them hold the brake while you tighten the bleed screw. Do this as many times as necessary until brake fluid only with no air comes out.
Reinstall drum and tire, top off brake fluid.

check your break lines or remove the tires and pull off the brums and look at the automatic adjusters
