New Williams team boss James Vowles has passionately sought to give the team a way to catch up on its ageing Grove base's facilities.
Under F1's financial rules teams have a $36 million allowance over a four-year period to invest in capital expenditure, with an exception made for wind tunnels.
But according to Vowles that figure is nowhere near enough if Williams is to catch up with F1's top teams.
However, talks to find a solution have not produced any results yet, with rival teams keen to secure bigger CapEx allowances for themselves as well if any concessions are to be made to Williams.
"Some teams jumped on that bandwagon to say, but actually, we would like to have a little bit more CapEx," Mercedes chief Toto Wolff described the discussions.
McLaren's Brown says he is "sympathetic" to Williams' situation, but warned that any solution for the team cannot ignite another free-for-all spending spree.
"I am not a fan of bigger allowances, just in general. I'm sympathetic and cooperative on Williams having the chance to catch up," Brown told Autosport's sister website Motorsport-Total.
