Burks was a member of a student committee of the Nashville Christian Movement for Human Rights and an early volunteer to participate in the Freedom Rides in the Spring of 1961. In order to get permission to leave campus, she called her mother in Birmingham to invite her and her friend Lucretia Collins to visit her.
The first Freedom Riders to reach Birmingham from Atlanta, Georgia on May 14 were met by mob violence and no drivers were willing to carry them onward to New Orleans. Many elected to fly from Birmingham in order to reach New Orleans in time for a scheduled rally. Later buses were escorted by police and National Guardsmen. When Burks and her group arrived in Birmingham from Nashville on May 17, they defied the city segregation laws enforced at the bus station. They were placed in "protective custody" and driven back to the Tennessee state line by Public Safety Commissioner Bull Connor the next day. Many returned to Birmingham by private car for the next leg of the trip. In Montgomery on May 20 they were met by an angry mob which was eventually dispersed by Alabama Public Safety Director Floyd Mann. The group holed up at First Baptist Church, held in siege by a crowd outside.
The group continued to Jackson, Mississippi where they were arrested en masse and charged with breach of peace. Most were sent to the Mississippi State Penitentiary to serve their sentences. Burks was expelled from Tennessee State following her arrest. She won a court judgment reinstating her as a student and completed her degree there. The University awarded her with another honorary degree in 2008.
In August 1961 she married fellow freedom rider Paul Brooks. In 1962 and 1963 she and her husband worked in voter registration campaigns in Mississippi, co-editing the Mississippi Free Press. She went on to open a jewelry boutique and to work as a social worker, teacher, and cosmetic sales manager.
