Question

What is a jake break ?

I was just curious because when i drive down the road i see signs that say no jake break

Answer 1

A jake break is using the compression of the motor to slow the truck down.It`s a switch that stops the fuel going to the motor.There`s no break fade like when you use your air breaks.Brake fades happens when the drums heat up and expand and the pads no longer have full pressure against the drums.Jake breaks are really loud so they have signs saying not to use them where they would get noise complaints

Answer 2

A jake break is an engine brake that semi trucks have and use to help them slow down with out hitting the breaks It makes a very load sound from the exhaust when the jake break is applied.
