First time having manual brakes, are mine bad?

I did mess up my back. Out on L&I two weeks and months of PT and Chiropractic adjustments. At the T section and RED light, the field was 10 feet below the roadway and the impact of jumping a Bucket truck was bad. The Mechanic was gone when I came back to work on light duty. Truck was auctioned off as scrap but the whole Bucket system and maintenance bins were good.
Damn.... You Were Blessed. I had a crane operator release the brake, with me in the middle of a 90' x74' 4 pc Chinese Baptist church truss set. The idiots I worked for didn't want me to brace them ( that's bs, takes to long, bla bla) well, we came back the next day, and they were all leaning, I crawled way up there, tied em off, he pulled em with the crane, past where they needed to be, let em rip with me up there, and drove away before I could wipe and climb down....
