Twist the brake fluid reservoir cap counterclockwise and remove it. Remove as much brake fluid from the reservoir as possible by sticking a clean rag inside the reservoir. When you remove the rag, be sure not to place it on any painted or plastic surfaces. Brake fluid will strip paint and deteriorate plastic.

Thanks this was great. Additional instructions are required about how to disconnect the reservoir from the master cylinder. I've broken so many plastic bits on my Volvo that I was scared to really put much force into getting the reservoir off. I kept thinking "There must be a trick..." but no there's no trick you just have to pull really hard while doing your best to not damage the reservoir. Could have saved me some time as I stared at it wondering what the "trick" could be.

There's also a plug on one side of the old master cylinder that you will need to take out and put on your new one.

Thanks again for posting these instrux.
