Trailer clonk. What is it please?
My trailer a de graaf 1300 clonks when I brake on the car because the piston is compressing. At the weekend I replaced the damper and it has made a limited difference however there is still a clonk. Is the main issue now that there is too much movement before the brake actuator engages on the piston???
I'm hoping it's just a matter of adjustment now but any advice would be appreciated.
