Reading triumphed at the Priestfield Stadium by one goal to nil thanks to a second half strike from Anthony Rougier. They now occupy sixth place.
Speaking in the absense of player boss Andy Hessenthaler, Brown told the Gillingham official site: "Reading are a good outfit. I thought they would come here just to catch us on the break. When you have someone with the pace of Nicky Forster up front it's not that hard to do.
"I thought they played very well, they sucked us in and broke with a goal."
Brown went onto admit that he was a little less than impressed with his sides display.
He added: "I think that it started very well for us. In the first ten minutes we had a lot of possession and looked quite lively. It's the early goal your looking for at home and unfortunately today it didn't come.
"In the second half we had a decent start but again it fizzled out and they managed to get on top, Forster caused us all sorts of problems."
The Gills will hope to get their ship back in order next Saturday when they play Sheffield Wednesday, now managed by Chris Turner.
