Hmmm. A suppressor with an extra blast baffle would be quieter than a supressor lacking that extra baffle, right (in theory)? It seems weird though that a brake makes a gun louder, but when used with a suppressor it would be (possibly) quieter? Unless I'm misunderstanding.
It does not make the gun louder, it is just perceived by you and those around you as louder because of the gas being re directed. The advantage is lower recoil.
A supppressor works by capturing the hot gases exiting the barrel by allowing the gas to expand and cool. This lowers the noise level as you do not have those gases exiting out of the barrel at supersonic speed.
The first baffle in your suppressors baffle stack is the blast baffle, and being subject to immense heat and pressure, it takes the brunt of the force from the gases. Usually the blast baffles are made from iconel for rifle cans, and in pistol cans with mostly aluminum baffles, the blast baffle will be the one that is steel.
When using a brake for your suppressor mount rather than a flash hider, you should have no perceived difference with the can attached: the suppressor is still doing its job. However, with a brake attached, it is taking a lot of the brunt of the round, sparing the blast baffle in the can, and extending the suppressors life.
Without the suppressor, it will seem louder to you with the tradeoff being lower perceived recoil. However, presumably you will shoot with the can as much as possible. I would rather replace a muzzle brake mount for wear and tear than have to deal with damaged baffles.

Wouldn't you rather see that on your brake than inside your suppressor?
