Bruce Greeff's Surge Brake Rebuild Instructions
The trailer is not a major problem to rebuild. But there are a couple of points to note:
The gas strut in mine was not comparable to anything on the standard
fleet of cars out here, but the local fitment centre were happy to take
it away and have one made to match. Did not even cost much - but it did
take a week or two. The unit as fitted is a modified truck cab damper by
the look of it - similar to the struts on a car boot, but shorter and
thicker. They did not give me the specifications but I think it is
around 700N (157 lb) preload.
When the time comes to extract the whole lot, make sure you have
removed the grease nipples, they protrude and foul the inner workings.
Make sure the stroke length of your gas strut is right - if it is too
short you have to overcome the gas preload to set the reverse lock. This
can be impossible, let's not go into how I found out.
In case you, like me, have difficulty working it out: you dismantle
the hand brake assembly first, remove the grease nipples, remove the
bolts fitted radially around the front collar, and remove the bolt that
is cunningly hidden in the tongue, just in front of the body of the
trailer. Then it all slides out, without much force required, mine did
need a little persuasion to break the corrosion around the front collar.
With a clean up, and new grease and damper the trailer is a pleasure to
