LAND ROVER DEFENDER TD5.REPLACEMENT OF BRAKE MASTER CYLINDER

This is just a short video of me replacing the brake master cylinder on my Defender.
The symptoms of the "defective " previous brake master cylinder were as I have explained in the video, a kind of brake fade.
What I didn't explain was these symptoms were only apparent after a bit of a frosty cold spell earlier this year. What I think might have happened is that some water that was in the brake fluid froze, expanded, and possibly damaged some sort of seal within the master cylinder. I read that dot 4 brake fluid apparently attracts moisture. If any one who watches this video has another explanation I would be very grateful to read it. Thank you.
