Welcome to Justanswer, My name isXXXXX am here to help.
so what do you think about my question?
This should but I have seen it happen
When parking on a hill especially will lock up the parking brake not the normal brakes though
you wouldn't use the regular brakes if parking on a hill? you would only use the emergency brake? how come
No you would not want to use either if possible
What you can do is park the vehicle with the wheels pointed away from the direction of the curb
Then let it roll back and if your not going to be using this for a long time then you will want to use blocks
If you have the E brake on it can seize I have seen it
But allowing it to roll back and touch the curb with the wheels turned then you are fine in park but can lightly use the ebrake if needed
if you put the truck in park without blocks should it hold?
Yes it will just have the wheels pointing away
i have a case where a tow truck driver parked on a hill and used blocks. he knew he had problems with his brakes. his passenger then moved the blocks, the truck rolled down the hill and hit my client's building. who do you think is at fault?
This may have been a manual transmission
Most tow trucks are if so it should have been in gear
As long as proper steps were taken the vehicle should not have rolled back. In park the only way possible is if the park pin broke
If its manual transmission and was left out of gear neutral then thats a big mistake on the drivers part
As to who is at fault this is something you will want to speak with a attorney of law.
so the truck should be in gear, wheels turned, with parking brake on? and if so, the truck shouldn't roll even with no blocks?
in gear if MT park if AT
and if the parking brake fails that means the parking pin broke? what symptoms would you experience if you had a problem with the parking pin?
No if its a automatic transmission and it rolled while in park the parking pin would have to break
If the parking pin is broke it will move while its in park
