I had that same problem until I fixed my emegency brake. 
When I was first taught to drive a school bus the company had only stick in their fleet.
One of our tests was to drive a bus to this hill that was so steep it reminded me of driving the streets of San Francisco.
At the very top of the hill the nose of the bus was so high in the air the driver could not see the road for the decent. To pass the test we had to hold the bus at the top of the hill using only the clutch, no break allowed.
We had to ease off the clutch to move forward and only given a --2 inch back roll--and no gunning the gas.
Mind you this was not an empty bus but one filled with students, the adults at the school and the DMV personal that decided if one was going to get their license to drive 50+ kids to school and back.This was in Norfork Va. and the company gave us free reign to drive the bus with an instructor as much as we we wanted to for 8 days before the written and driving test for DMV.
Anyone who has lived or visited Tidewater VA. knows about the tunnel system there, rather narrow for a bus with mirrors that stick out 2+feet.
We spent hours driving through those tunnels keeping the back tire on the yellow line, with only perhaps a 3 inch clearance from the mirror to the side of the tunnel.
By golly we learned to parell park these big rigs between two other buses with only a 6 inch clearance from those in front and those in back.
I guess looking back the worse thing was for me when Hubby and I were at the O Club on base and some one asked me what I did for a job I would perk right up and with pride tell them I was a school bus driver and Hubby would look down embarrassed as if I had said I cleaned restrooms at the bus station.
It was that every day twice a day I brought 100 children aged 6-8 from their homes to school, then drove in the inner city for a highschool a bunch of drugged up gang members from home to school and back again with no problems, a huge responsibility for a bus driver, having the lives of all those kids in my hands was something that to others placed me under a worker that sat all day in an office.
Had I said I was a day care worker in a job that cared for children of working parents, ----Good for you, hard job.
But I was just that unknown person that transported their kids in all kinds of weather to and from school, responsible for the kids that had health problems I knew nothing about, facing unknown mental problems or kids with weapons in that small space--
Sorry folks, I have gone not only off topic but one thing lead to another here. It is stuff from the past that led me to remembering the frustrations we all face in life.
Having a bad day here, as you may guess.
Pet peeve here it is, putting down someone who has a job that one cannot or want to do and attaching negative feeling for that job.
Yacht club in this area had a fit when a Doctor married a woman that was a very skilled hair dresser. I asked my Mom why the problem and she told me that no one wants to socialise with their barber.
