I have a 2003 Ford Crown Victoria with about 75,000 miles. I have recently done a brake fluid change. From the look of the old fluid, it looks like the brake fluid had never been changed. It had a blue-green tinge to it, which suggests there is oxidized copper in it. In my other cars, When I lived in L.A., where it is extremely dry, I usually had brake fluid changed every 2-3 years. I have never seen blue-green tinge to the old brake fluid, and the brake pedal feel had never changed due to the fluid change. When I bled the brake on the Crown Victoria, there was not air coming out, so the spongy feel before the fluid change was not due to air in the system.
Anyway, after the brake fluid change, the brake feels much less spongy and certain. When I was test driving the Crown Victoria, I thought the spongy feeling in the brake was normal, since it is designed for people who learned to drive before the 1970s. Now, the brake feels closer to how Honda Accord and Nissan Maxima felt.
Is it normal for the brake to feel more solid and certain after a fluid change?
Thank you for any input.
