Yes, they/we are. Good luck once you start the project. be careful and patient, something WILL go wrong.

How's that for confidence building? Ha!

Yes, I did not change my booster an have had no problems using it. I was warned, yelled at, told I was going to DIE if I didn't swap it. I've had no probables.

I love the advice some of the people can give, but there are zealots out there for whom their experience is the only acceptable reality. I was told the same about using Ford wheels - my wheels would sheer off within a week!!!! They've been on for over 11 years with no problems.

Now, would using a disk-brake booster be better? I would not argue against such a question. Is it absolutely necessary? Not to me.
