Glory is facing the threat of fines or even the docking of competition points after .
The alleged perks such as accommodation and car allowances - plus payment of third party agents' fees - went unreported by the club over the past three seasons.
However, Brewer says the Glory's recent trend of operating well within the salary cap means the club is not in danger of exceeding the limit - even if it is found guilty.
"Even if all of the alleged benefits they are referring to are included into our salary cap calculation, we have sufficient capacity - two or three times over - for any of those benefits," Brewer said on Friday.
"The previous couple of seasons we have been upwards of $150,000 under the cap.
"From our calculations and the FFA's calculations, clearly (the alleged breaches) are not significant enough to exceed the salary cap."
He added in a club statement later in the day: "The notice received from the FFA was primarily in relation to an alleged failure to disclose certain non-cash benefits to players.
"The notice was not in relation to any alleged breach of the club's salary cap in this, or in any season.
"Categorically the club has always operated within the cap on each and every A-League season."
Brewer continued: "The club’s position on the alleged benefits, which relate to non-cash accommodation and motor vehicle benefits has been reviewed internally over the past several weeks.
"The club has not deliberately tried to conceal anything and has worked in a very positive and productive way with the FFA. We will continue to do so as we look to finalise this matter over the next week."
