Ifor Williams Brakes seized


adey

Recommended Posts

I`ve acquired a flat bed Ifor Williams trailer to move my Mk 3 landy chasis from my home garage to workshop. It was cheap and the reason has become clear. I have replaced all 4 sets of brake shoes and the cables as all were seized and cables rusted. The biggest problem is the dampener on the tow hitch (the tube that moves and applies the brakes on the trailer when the tow vehicle brakes); that has seized also. Does anyone have a genius solution for un-seizing this. I`ve tried greasing and applying WD40 to no avail

the damper is inside the hitch ,or directly under it . it sounds like the slider(that the ball socket is fixed to ) has stuck . Be careful if you

use heat as iirc the hitch slides in nylon bushes .

A mix of diesel and oil in the grease gun and pressure it in thru the grease nipples may free it off

cheers

Rather than trying brute-force stuff to get it sort-of working, I'd suggest careful disassembly and an if-in-any-doubt-replace-it approach.

Why? Well, someone I know when they really-really needed every-last-percent of trailer braking capacity which it turned out wasn't there managed to flip a loaded trailer across the central-reservation of M5 some years back, resulting in the motorway being closed both-ways for five hours .

Life's just too short to skimp on *anything* relating to brakes.

Thanks for all your advice. I took the hitch off the trailer and from there I could see that the cylinder/piston had a lot of surface rust on it, some of which was flaking off. I think this makes it clear that it wouldn`t work effectively even if it was cleaned. I will order and new one and see if I can remember how to put it all back together again
