Ya'll may not believe this but if your pull starts fishtailing DO NOT hit your brakes. You should excelerate to regain control.
Been there, done that. I absolutely disagree, NEVER increase your speed untill you have control over the vehicle.
I was doing 70 km/h on a narrow road with lanes of trees on both sides. When the tandem trailer began to swing, i accelerated to 90 km/h.... The tires began to squeel and when the front tire of the car rode over the roots sticking out on the foot of the oaks, (missing the actual trunk by inches) i realised that i had no control and should loose my speed ASAP...
I slammed the brakes as hard as i could, the car swung 180ï½°, while slingshotting the trailer against a tree, half into a ditch. Later that day I remember that i saw the underside of the trailer floor in my rear view mirror when it swung over.
Lucky for me the ball hitch cracked open so i didnt stay hooked to that trailer.
Afterwards, i can tell you that the brakes didnt work: When i noticed the first fishtailing, i released the gas pedal and let it roll. Didnt really help. Then i accelerated. Didnt help.
Then i tried braking. no effect. (later we found that the brakes of this trailer never worked, so braking with no trailer brakes is dumb anyways.
When neither of those actions had any effect, i threw it into 3rd gear and hauled into 90 km/h. At this speed i was even less able to control the vehicle.
Later i had 1 or 2 of these occasions where the trailer began swinging. Like the time i had 2.5 ton of concrete on a short and high tandem trailer, behind my Volvo 850.
Just hitting the brakes HARD (actuating the surge brakes) and releasing the brakes right again, allmost immediately pulls you out of the swing.
Because the trailer still brakes when the car is freewheeling, changes the frequency of the swing. I had to do this at several trips and it worked all times.
If a trailer is fishtailing agressively, please DONT increase your speed because more speed = less control. I learned it the hard way.
