Can I add brake fluid if it's low, like adding oil and where do I put the brake fuild?

On a 2002 mustang it is the reservoir for brake fluid. The fluid level should not be high enough to leak. One way to get too much is if someone adds fluid to the reservoir because the level is low. Its normal for the level to go down as the brake pads wear. The piston pushing on the brake pad requires more fluid to force the brake pad into the brake rotor as the pad wears. If you put more fluid in and later replace your brake pads, the pistons must be pushed back to their original position to install the new pads. Pushing back on the pistons causes a backflow of fluid to the reservoir. Since you added more fluid earlier there is now too much and it can overflow. If this is your problem you can bleed out excess fluid. The valve to bleed the fluid is down behind the wheel near the brake pad calipers.

hi
you have sorted the problem, the fault code that you had is caused by low transmission fluid. BUT.....
you still have to check the transmission for leak, to find out why the fluid went down that much
Good luck

Have a look at the automatic transmission fluid.
Under the hood should be 2 long dipsticks, usually they have a colored plastic handle so you can see them more easily.
You will need to identify them, perhaps ask a friend for help.
One dipstick is for motor oil, the other for automatic transmission fluid.
The automatic transmission fluid should be redish in color, that is a dye put in the fluid so you know it is not motor oil.
Check that fluid, your owner's manual in the glove box will tell you whether to warm the eingine up first before you check it.
If the fluid is low, add some with a long funnel, only add a pint at a time, and check it about 5 minutes after you add it.
Repeat this until it shows full.
Car parts stores sell quarts of automatic transmission fluid.
If you pull the dipstick from the transmission and it is not low, and the fluid is clean (not black coloured), you may either have a transmission that has failed, or your brakes may be sticking ( like the emergency brake is on).
Be blessed

Have the car on, in park, emergency brake on. Under the hood, red dip stick. From line to line should be 1qt. This is best done when the cars warm. Add until the 2nd line. Get in your car, hold the brake, slowly put it in reverse, neutral, drive, 3,2,1 then 2,3, drive, neutral, reverse, park. Repeat a couple times to move the oil around, and you're good to go.

Did you bleed the brakes? Pump the brakes?

Well there is your brake fluid at the top right and trans fuild check when hot or cold and your oil but the powersteering fluid has a lid that is thin and locks into place usually on the left top side.It jusy says add or full

first thing to do is always check fluid levels... get car warmed up, then with feet on the brake pedal run it through all the shift positions from park to first...now put in park,leave car running and check the fluid level it shouldnt smell burnt and if low add a small amounts at a time till its brought up to proper level. start with half pints at a time..this isn't like adding car oil.
if this is good then its time to let a transmission shop have a look.

unhook the battery for about 15 minutes.

be sure you have the code for the radio if it's the anti-theft variety.

please take a moment to rate this solution thanks

there is a bolt you have to take out and you put the fuild in there im not 100% on where the hole is but if you get a hanynes maunal from a partsd store it wikll show you where it is

make sure the car is warmed up....hold brake and put in drive, reverse, cycle through all gears, and check it again....if it still show low, add
