Can I just pour brake fluid in reservoir?
If your brake fluid is at or above the “MIN” line, your brake fluid level is fine and you don’t need to add any. If your fluid is below the “MIN” line, carefully pry the reservoir cap off, and then add brake fluid until the level is just under the “MAX” line. Do not overfill. You may need your brake system serviced.
Do you put brake fluid in the master cylinder?
Almost all master cylinders on the market today have a max line on the side. The reservoir should not be filled past this line. As you drive your car and apply your brakes, your brake system heats up, including your brake fluid. As brake fluid heats up, it expands.
Should the brake fluid reservoir be full?
The fluid should be in between the two marks on the brake fluid reservoir (see photo above). If it is below the low mark then you need to add brake fluid. If it is above the full mark then you might have more serious problems. If your brake fluid level is above the full mark then your brake fluid may have water in it.
What are the signs of low brake fluid?

What happens if you put too much brake fluid in the reservoir?
If the master cylinder is overfilled it will not allow enough room for the brake fluid to expand due to heat expansion. The expanding fluid will cause the calipers to apply creating a residual drag.
How much fluid should typically be in a master cylinder?
The brake fluid should be up to the “Full” line on the side of the cylinder or within 1⁄2 inch of the top of each chamber. If it isn’t, buy the proper brake fluid for your vehicle and add it until the level meets the line.
How long does it take to change a master cylinder?

If you have an idea of how to do this yourself, then you can save the money on the labor costs by doing this yourself.
Can a car stop without brake fluid?
