Brett came of a naval family: both he and his brother, John, were naval officers, and another brother, Timothy, was comptroller of accounts in the Navy office.

In Robinson’s first survey on the royal marriage bill, March 1772, Brett was classed as ‘doubtful, present’; in the second as ‘pro, present’. For the remainder of this Parliament he was a Government supporter, although he voted against them on the naval captains’ petition, 9 Feb. 1773, which Howe sponsored, and on Grenville’s Act, 25 Feb. 1774. The first sign of his turning against Administration was on 11 Dec. 1775, when he spoke against extending the American prohibitory bill to Georgia.
Brett was appointed to the Admiralty Board under the second Rockingham Administration, and brought into Parliament for Dartmouth at Howe’s recommendation.

In Pitt’s Administration he was again at the Admiralty Board under Howe, and became one of its principal spokesmen in the Commons. He left office with Howe in 1788, but voted with Pitt on the Regency.
He died, ‘far advanced in years’,
