Trailer clonk. What is it please?

Hi

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.

Cheers

PH

easy fix. probably the brake cables/rod is too loose so when you break there is a clunk as the draw bar slides inside the tube and hits the break lever that pulls the breaks on.

Had this on my trailer.
tightened up all the bits and adjusted the breaks and hey presto no clunking

Agree with above - likely adjustment if you've replaced the damper. Make sure the brake actuator / pivot is hard up against the back of the drawtube.

That will be it then. Thanks a lot guys. Actuator is about an inch off the piston.
