One of Brown's central campaign promises was his "100-Day Plan for Muni", in which he said he would fix the city's municipal bus system in that many days. Brown supported the "Peer Pressure" Bus Patrol program, which paid former gang members and troubled youth to patrol Muni buses. He claimed the program helped reduce crime. He fired Muni chief Phil Adams and replaced him with his chief of staff Emilio Cruz. In 1998, Brown was mayor during the summer of the Muni meltdown as Muni implemented the new ATC system and he promised riders there would be better times ahead. A voter-approved initiative the next year helped improve Muni services. Brown increased Muni's budget by tens of millions of dollars over his tenure. He later said he made a mistake in overpromising with his 100-Day Plan.
