    Thanks in advance for any help.

    The handbrake lever looks black in the picture and also looks like a standard one.

    The "cylinder" is actually a wedge and roller expander, and there is little that can go wrong with them (unless assembled without the rollers or really severe wear). More likely is it is rusted solid or the linkage is not adjusted so as to pull it far enough to move the shoes. One point to watch is the possibility that the pivot mount for the bell crank is either loose or bent, resulting in lost motion.

    Also in the picture I don't see the return spring - not sure what effect it being missing will have, although it could result in severe wear of the expander due to continual movement.

    I would disassemble and examine the expander before ordering parts. Note that handbrake details changed during production, and some parts need the chassis number - but even then the assembly may have been changed after manufacture.

    Transmission brake pulled apart. Thanks John for the advice. It was very jammed but careful pushing and pulling with crc got it functioning. Pics attached. Is it possible that the wedge and roller can be too worn? How much movement is a wedge meant to extend when lever is pulled?

    Leaky! This seal needs to be replaced I think!? Sikaflex was evident all around.

    I have never measured how much they expand the shoes, but it only needs to be a small amount - the adjuster takes almost all the free play. From what I can see in the picture it looks OK. As long as the rollers have no flats on them and the wedge has not got grooves in it, the expander will be OK. Note that there are two types of expander, I think from your picture yours is the later type. The plungers need to be correctly assembled (see manual) - same applies to the adjuster.

    As you have noticed, you should have drained the transfer case before disassembly! If you remove the brake backing plate you will find there is a slot designed to allow oil leaking through the seal to not contaminate the brake. Unfortunately, it is often blocked!

    Thanks John much appreciated. Looks like they will do tho job. Is there a lubricant/grease that you would reassemble with? Obviously don't want to extending/seeping out and onto pads etc!

    Some more spraying.
    Plenty of etch primer underneath all panels/parts.

    Cheers, Nick

    A high melting point grease will do the job.

    As Colin says. It is not critical, needs to have just enough grease to keep the water out and not get on the linings.
