With Brown amongst many others away on international duty in November, the Warriors bounced back from a disappointing 19-9 loss against the Scarlets with a 19-15 win over Newport Gwent Dragons last time out.
All that means Gregor Townsend's men currently lie third in the GUINNESS PRO12 table, level on points with Ulster and the Ospreys and only a point behind league leaders Munster.
They do however top their European Rugby Champions Cup pool, with two wins from two, and although Toulouse boast one of the most formidable packs in European rugby, Brown insists his side have invested a lot of time in ensuring their game is up to scratch.
"We are top of the group and this the best chance we have had in a European competition so we are going to go down to France try to keep that up," the 25-year-old told the Scottish Herald.
"Up until the weekend (against the Dragons) our scrum has been up and down, maybe 40 minutes of good scrummaging and then a few bad ones.
"Something we have put emphasis on is our concentration; we cannot go in and scrum really well on our own five-metre line and then go 30 metres up the pitch and slacken off.
"There was a big emphasis on that last weekend, which showed because we got four penalties and could have had a few more; this will be more of the same.
"We know how they scrum, we have reviewed it so it is a case of getting our drills right, getting our height right and making sure we are concentrating for everyone.
"We are confident in the way we scrummage and, if we scrummage well, it does not matter who we come up against.
"There are always going to be one or two or three in a game where you don't quite get the rub of the green; it is about flushing that, going to the next one and making sure that you get solid ball."
