NO... do not remove the lower part, that is even worse. The lower part of the mount is not only held in place by the bolts you see going through the upper half, but also by a big bolt that also holds the lower control arm in place to the sub-frame. If you remove that big lower bolt, then your back side control arm might come out . You can see item 17, that is the bottome part, and you can see item 13, 12, and 11 go through the front of the subfram through the rear control arm and through the bottom part of the engine mount. Much worse trying to remove that since it has a lot or pressure on it. best to either bypass that line and leave the old one in place untill you can get the engine up enough to unbolt the top piece and move it out of the way enough to place the brake line in there.
