Hi guys,
The cable brakes I am referring to, operate as surge brakes and are attached to the main wheels of the T/D. They work by a cable pulling on a lever/cam to expand the brake shoes. The cable is pulled by a lever at the front, same way as hydraulic brakes work by a lever or as some are, directly inside the surge mechanism. Cable brakes are are strictly "mechanical" as opposed to hydraulic where there are no levers or cams etc. to push/pull the shoes onto the drums.
I am unable to fit electric brakes as they are beyond my budget but "mechanical" or hydraulic brakes are the type I can fit and are used here in Aust. for trailers and small boats up to 1 ton, maybe even more.
The pros and cons of both types are listed below being what info I could find.
Hydraulic brakes, Surge type. (Surge brakes are called "over-ride" brakes here in Aust.)
Pros :-
Easy to fit.
Are very positive in operation
Relatively easy to maintain.
Very few parts
Nothing to stretch over a period of time.
Cons :-
Prone to water infiltration at the slave cylinder and the master cylinder reservoir
Brakes will fail if water enters the line.
Can be damaged easily if not installed correctly
Needs a "flick-over lever" to reverse the rig
Cable operated brakes. Surge type.
Pros :-
Work in all conditions
Can be adjusted for cable stretch
The mechanism is unaffected by water
Relatively easy to maintain.
Cons :-
Cable can get in the way of trailer attachments, eg, Jockey wheels.
Cable can stretch.
Cable will rust over time.
Cam/lever in backing plate can seize if not maintained regularly.
Prone to damage on rough roads
Needs a "flick-over lever" to reverse the rig.
I want to fit a "jockey wheel" at the front so I can raise the trailer off the tow ball/hitch when I am stopped and need the car to to go somewhere without the T/D. A jockey wheel makes it very easy to maneuver the T/D when attaching it to the car or if the front needs to lifted for leveling.
So my question is, what system of brakes do you guys use as surge brakes? "mechanical" or hydraulic? (Mechanical means links, levers etc)
Also, how do you lift the T/D off the hitch on the car without breaking your back?
What do you stand/rest the front of the T/D on?
Do you simply let the front sit on the ground, (not a good thing by any means) ?
