I have to add brake fluid to my car about every 3 weeks I don't know why it is loosing fluid.

check around the brake booster at the brake rod end of the master cylinder
it will either be going into the brake booster and being sucked up by the vacuum and burnt on brake application , or leaking down the inside of the fire wall under the floor mat
indicates that anew brake master cylinder is required

Have the codes read. Check the brake fluid level. Wouldn't surprise me if low brake fluid doesn't kill the engine know days.

you need 2 persons to bleed brakes one have to seat inside the car and pump or hold brake pressed,Add brake fluid to the top ,next ask someone to pump brake few times when it will get hard,then hold while pressing loose bleeder half a turn the pedal will go all the way down and still need to be pressed ,fluid will run through the bleeder ,then tight bleeder back and repeat the steps ,pump, press, bleed ,few times per each brake caliper ,don't forgot to add fluid to the reservoir

Should be a white plastic reservoir under your hood on the firewall on the driver's side. It will have a cap on it. Should be one for the brakes and one for the clutch.

LOOK ON ALL YOUR WHEELS TO SEE IF THEY ARE WET FROM OIL THAT IS THE PROBLEM TELL YOU MECHANIC YOUR LEAKING BRAKE FLUID FORM WHICH EVER BRAKE CALIPER OR WHEEL

it appears from my info, that the clutch master cylinder is connected by a tube to the brake master cylinder resevoir, and it gets it's fluid supply there. Fluid would therefore be added AT THE BRAKE RESEVOIR. fIND THE CLUTCH MASTER ON THE FIRE WALL AND VERIFY THIS THOUGH, AS i CAN'T SAY THAT i REMEMBER SEEING THIS IN PERSON. gOOD LUCK, AND GET BACK TO ME WITH ANY MORE QUESTIONS.(Sorry, don't type well, and accidently hit caps lock)

Hi!

YES! You should be very concerned. The breaking fluid must never leak. It can happen anytime that the car loses all breaking power, by leaking more fluid and by air entering the system. Please let a professional check and repair that breaksystem.

Best regards!

You can add brake fluid when its cold just make sure you are adding the right fluid most vehicals take DOT 3 brake fluid, look inside your owners manual in the recommended fluids and lubricants section and make sure thats the right brake fluid for your ford......

Use a Dot 3 conventional fluid and add to a clear plastic reservoir you will find under hood directlty in front of the steering wheel.There is a float inside which will detect low fluid and trip the indicator.Big concern is why is the brake fluid low in the first place?This will almost always mean wearing brake pad linings as the fluid will displace the missing lining thats worn off the pads.This probably is an indication that near future brake repairs are on the way which will include brake pad replacement. The other sitation you may enounter is once the pads are replaced,you will then be in an overfilled situation to where the fluid will have to be removed to have the correct amount. I would probably get a visual inspection on the brake lining wear then elect to add fluid at that time or replace brake pads.

pump brakes up and hold. have someone fill up resovouir. put top on and release brakes.
