On my 1994 Mercedes E320 wagon,I was trying to installed the replacement brake master cylinder. One of the two bracket are giving me a fit that holds the bottom of the ASR pre-charge box/part due to limited space. As a result of wiggling the brake master cylinder and the bottom bracket, the push rod inside the brake booster came loose. I read somewhere just put the push-rod into the master cylinder, and installed the master cylinder like normally would. It seems to have worked.

If that is the case, then I assume that the person who did this saying he does not know if it supposed to be permanently attached somehow or not. He also indicated that the pressure between the booster and the brake master cyclinder should keep it in place.

Any truth to that? Comments, advice, feedback is greatly appreciated.
