You should check your brake fluid every three months to make sure the levels are okay. If the levels are down, replace the fluids immediately...better safe than sorry.
PS should be 18000 miles and brake fluid about 30000 miles PS should be 18000 miles and brake fluid about 30000 miles
Usually it's low brake fluid or a problem with the abs. Check the brake fluid reservoir. Often the brake fluid will go down as the brake pads wear and the calipers has to travel further.
It depends on the type of fluid and level of contamination or heat. if there is no problem with the fluid it should be left alone!
In a Case 580 M backhoe loader, brake fluid is added to the brake fluid reservoir, which is typically located near the driver's side of the machine, often near the master cylinder. You should check the fluid level and add the appropriate type of brake fluid as specified in the operator's manual. Always ensure the area is clean to prevent contamination and follow safety precautions when handling brake fluid.
The reservoir for each of these is usually transparent, so you can also verify the condition of the fluid at the same time. The brake fluid should be an amber color, while transmission fluid should be red. If you have an older car, you would check the brake fluid at the master cylinder, each side of which should be full. Be sure to close the lid securely after checking the fluid. The transmission fluid (on automatic transmition) is checked via a long dipstick, it should read between "add" and "safe". If you are in need of more transmission fluid, pour it in down the dipstick tube. A long funnel works well for this. Be sure to use the appropriate fluid for your transmission, they aren't all created equally. Or about 3,000 miles(about 3 months)
Brake fluid could be low. Check for leaky brake lines under the car also. Quite often older cars have rusty brake lines that leak fluid sometimes just a little bit but these should be repaired as they can blow apart when you hit the brakes hard and cause an accident. Check your emergency brake and make sure it as pulled all the way off also.
Usually every year or two you need to change it check your owners manual for their specifications
once a year

"Maint Req" stands for Maintenance Required - oil change, transmission fluid addition, brake fluid, battery check, tire pressure, brake pads, etc. Check your owners manual for the car to see what's required and how often.
Every 2 years
If, as you say, it needs doing then it should be done as soon as possible. Brake fluid seldom needs changing though it does degenerate over time, mainly by absorbing moisture. The precise detail will be in your manual. The fluid reservoir needs checking topping up occasionally and certainly will require it after a brake pad change.
