There is a good book written by Dr. David Allen White entitled "The Mouth of the Lion" which tells the story of Bp. Mayer, and Campos. If I remember correctly, the successor to Bp. Mayer was Bp. Licinio Rangel, who was consecrated by Bps. Tissier, de Gallaretta, and Williamson upon the death of Bp. De Castro. Shortly thereafter, I believe Rangel accepted a deal with Rome. Rangel's successor was Bp. Fernando Rifan. Someone can correct me if my info is inaccurate, but I think that's what happened in a nutshell.

There's one key point Dr. White made in his book, "The Mouth of the Lion" that I disagree with.

He claimed Bp. Castro De Mayer disapproved of Plineo Correa de Oliveira and broke ties with him because he was anti-clerical.

As I know that you speak Portuguese, Permanência published a book about Mons. Castro Mayer named "O Pensamento de Dom Antônio de Castro Mayer" (The Outlook of Dom Antônio de Castro Mayer). I guess that's what you've looking for.

Here is a letter from Bishop Castro De Meyer on TFP. He had previously worked with them for years. This is the Bishop's response to a mother who lost her son to the TFP cult. Bishop Meyer called the once-Catholic group an "anti-Catholic, anti-clerical heretical sect.

This letter was published in the Campos daily, La Folha de Manhspan in 1991; the original text, however, is dated 1984, two years after Bishop de Castro Mayer’s break with TFP. It appeared in Le Sel de la Terre, [no. 28, Spring 1999], in an article entitled “Docuмents sur la T.F.P”.

Dear XXXXX,
I owe a response to your grieving letter of September 24, which, as the postmark indicates, you sent me on September 25. [1991]
 
In this case, I can only offer the sole advice: pray, pray much, above all the Rosary or at least the five decades of the Rosary, asking the Virgin Mother, Mediatrix of all graces, to enlighten your son and make him see that TFP is an heretical sect because, in fact, although they do not say or write it, TFP lives and behaves in accord with a principle which fundamentally undermines the truth of Christianity, that is, of the Catholic Church.
 
In fact, it is de fide that Jesus Christ founded His Church — destined to maintain on earth the true worship of God and to lead souls toward eternal salvation — as an unequal society, composed of two classes: one which governs, teaches and sanctifies, composed of members of the clergy, and the other — the faithful — who receive the teaching, are governed and sanctified. This is a de fide dogma.
 
St. Pius X wrote that the Church is, in its very nature, an unequal society, meaning that it comprises two orders of persons: shepherds and flocks, those who belong to the various ranks of the Hierarchy and the faithful multitude. These two orders are so completely distinct that the Hierarchy alone has the right and authority to guide and govern the members to the Church’s ends, while the duty of the faithful is that of allowing themselves to be governed and to obediently follow the way given by the governing class (The Encyclical, “Vehementer”, February 11, 1906) [7].
 
And the entire history of the Church, as can be seen in the New Testament, attests to this truth as a fundamental dogma of the Church’s constitution. It was to the Apostles only that Jesus said: Go and teach all nations. Too, the Acts of the Apostles show us the life of the Church in the times following Jesus Christ.
 
Because of this, it is a heretical subversion to habitually follow a lay person, therefore, not a member of the Hierarchy— as the spokesman of orthodoxy. Thus, they do not look to what the Church says, what the Bishops say, rather what this or that one says…. Nor does it end there: this attitude — even if not openly avowed — actually positions the “leader” as the arbiter of orthodoxy, and is accompanied by a subtle but real mistrust of the hierarchy and of the clergy in general.
 
There is a visceral anticlericalism in TFP: everything that comes from the clergy is prejudicially received. Basically, it holds that all priests are ignorant, not very zealous or interesting, and have other such qualities. Well, then, keeping in mind the divine Constitution of the Church which was instituted by Jesus Christ, TFP’s habitual anti-clericalism, latent, makes it an heretical sect, and therefore, as I have said, is animated by a principle contrary to the dogma established by Jesus Christ in the constitution of His Church.
 
Nevertheless, TFP had a healthy beginning. There was a certain evolution of the apostolate carried out by the bi-weekly newspaper of the Marian Congregation of St. Cecelia, titled, O Legionario. As a serious and well intentioned movement, it sought to strengthen the intellectual and religious formation of the members of that Congregation and, consequently, of the bi-weekly’s readers. It was influential throughout Brazil. That was the era of [its] obedience to Monsignors Duarte and Leme.
 
I accompanied and approved its apostolate, also when it began to stray into an anticlerical spirit, which began by its consolidating its position and then reversing it by putting the clergy in tow behind a charismatic layman, with his monopoly on orthodoxy. Perhaps I gave it support beyond a licit point. I retracted it only when it became clear to me that my warnings were not being taken into consideration. They had become useless.
 
It is just to observe that the straying of certain members of the hierarchy …explains the TFP scandal, but it doesn’t justify the positions they came to take. Even less so, those of their leader, Plinio.
 
At this time, as I said at the beginning of this letter, the remedy is prayer. First, because without prayer nothing is obtained: Ask, Our Lord says, and you shall receive. It is necessary to pray, because charismatic fervor produces a certain fanaticism: individuals become incapable of seeing objective reality, of perceiving even fundamental errors, because of this inversion of following a lay person instead of the legitimate Shepherds of the Holy Church. So much more so when, as I have observed, members of the Hierarchy unfortunately and frequently utter words and take positions which any Catholic can see are dissonant from doctrine and from the guidance of the Church of the ages…..
 
I ask Our Lord that he grant you, and your entire family, a holy and happy Christmas and many years filled with God’s grace.
 
I ask that you pray for me, Servant in Christ-Jesus,
 
Antonio de Castro Mayer, Bishop Emeritus of Campos

Incred, I agree it didn't work out. Plinio may have begun with the best intentions, but his plan deteriorated into a cult of personality with Plinio's slaves worshiping him:

1.  his slaves praying to him in a mockery of the Ave Maria

2.  his slaves consecrating themselves to Plinio in a mockery of the Louis de Monfort's Consecration to Mary

3. his slaves laying on the floor on their faces and making a public confession to him, a layman

4. Slave # 11, Atila G. head of TIA, preferring time spent with Plinio to time spent with God as Moses did (as Marion pointed out)
