Hi,
Can anyone offer any helpful advice about a rod activated transmission brake on my 1986 Defender that will not seem to work even after stripping it down cleaning and greasing it before re-assembly. I have got both Haynes manuals restoring and owners but they are vague to say the least when it comes to the rod activated old timers
I am just about to change the cable just in case it has stretched! I know it sounds daft but even with maximum tension set at the adjuster the hand brake will not bring the shoes, each of which have plenty of meat left on them to bind on the housing which is bone dry with no oil contamination.
I have tightened the adjuster on the back of the housing on the transfer box side which just doesn’t do anything at all!
When the cable pulls the rod and moves the central piston that moves the rolling wedges
(rollers) and lifts the plungers how much lift is needed, what should I see? How much movement of the plungers? Surely it has to be considerable to secure the vehicle?
The hand brake lever pulls as if the cable is snapped but it isn’t as I have checked also I thought that perhaps the components may have worn due to metal against metal wear so I have enclosed images of the items.
Any help appreciated
Cheers
James
