why do they say at 15000 miles I need a brake fluid change?

Brake fluid is hygroscopic in that it attracts water I noticed you said 15K mileage. It is also time like rubber components. Water in a brake system creates rust and breaks down the lines, cylinders and calipers. It also leads to a spongy pedal and reduced braking. A proper brake job requires cycling the brake fluid. This is accomplished by opening the bleeder valves to correctly compress the pistons. It requires keeping the master cylinder full as to not introduce air into system up top. Bleeding the brakes after this is a must to get air out at the wheels. Most people pass on this maintenance leading to costly and dangerous situations down the road. I have seen pathetic examples of fluid that looks like 20K mile oil. I changed out a friend’s fluid a few years ago without telling him and he called me telling me how good his brakes were after changing his engine oil. Lol it does make a difference. His was like tar.
I have never seen brake fluid that looked bad at 15k miles. 150K yes.

I have never seen brake fluid need changing at 15,000. If so, this would seem to be a defect on letting water get into the system, and should be covered by the manufacturer. Honda suggests "changing fluid after 30,000 miles". Service department also changed fluid in the rear differential at 15,000 miles. It seems to me i read the government is investigating deal service charges. Most vehicles go to the junk yard with original brake fluid.
