How much fluid did you end up using?
I used 1.5 liters. Through Ebay I paid $15 for 3 liters with a $14.51 shipping charge. You can say I paid $10 per liter. I would think the ease or difficulty in differentiating between your old and new fluid would be determined by how many miles you had driven during the past 2 years.

I just read that you can get blue fluid (rather than the amber) in the USA, but you need to order it from the UK and it is very expensive.

Wayne did some checking and it appears that the US government has now stopped the sell of blue brake fluid after over 15 years of it being on the market. They have came to realize it is blue in color and the US reg is that brake fluid must be clear or amber. This is as of 2013 ruling. I had bought the blue in early 2013.

To change brake fluid you can rotate between the clear and amber to see a color change when bleeding the brake doing a brake fluid change. one change clear and next change amber, next time use clear and so forth.

Thanks very much WeGla250! I ordered 2 liters of "Febi Dot 4 Plus" fluid from rmeuropean.com (Mercedes-Benz GLA45 AMG 4Matic Sport Utility 156.952 2.0L L4 Brake Fluid) since I could pick it up locally. I paid $18 for 2 liters plus tax (so about the same price).

They just did this on my car. Very weird. Do they not trust their seals? I was happy to do it though, since I don't drive the car as much as I should. Any extra attention to the brakes in that situation is usually a good thing.

Brake fluid attracts water. After a couple years the water can be as high as 2%. There are charts showing reduced boiling rate of various brake fluids based on % water.

Old fluid with water boils at a lower temperature. Boiled water is gaseous. Gas has a high compression. That means the brakes won't work.

Flushing out old brake fluid is a bit paranoid for normal driving, but good insurance.
