Well last weekend the handbrake decided to stick on and after a few hits with a hammer it still wasn't much cop. So I decided to strip it down and see what's what.
Now I am always a little apprehensive when doing work on the old girl but I thought that I would just get stuck in as it all seemed to be easy.
Stripping everything off was easy. Off came the gearbox end of the rear prop, tie wrapped that to the ar trailing a arm. Then unbolted the hand brake drum, undid the cable and then unbolted the back plate. All in all it took me about an hour just taking it steady and cleaning things off as I went.
So the problem was that the actuator mechanism was stuck and wouldn't release under the power of the springs attached to the brake shoes.
Anyway after stripping it all down I started to build it up. Took me about an hour and a half, taking it easy and taking photos. Lol
So here we have the backing plate. It is as you will see it on the vehicle. To the right is the actuator where the cable connects and to the left is the adjuster.
Here is the back of the plate. The adjuster is attached by two 13mm bolts and the actuator (sorry if it's the wrong word) is held in place by sliding clips.
The adjuster first. Here you can see the main adjuster. It screws into the housing so provides adjustment when wound in and out by pushing apart the plungers.
Next I fitted the parts for the actuator. The centre plunger connects to the rod which in turn connects to the hand brake cable. When this moves in and out it pushes the two pistons out via the rollers. You have to make sure the rollers and the pistons are in the right way. If you get them arse about face when you pull on the cable they won't move at all as they are cambered.
Here's the actuator complete with the brake shoes in place.
The top of the backing plate is to the right. You can see I have marked the shoes before removal with Top Right and Bottom Right.
With the shoes in place, I then fitted the drum. I thought that this was best and besides, what nobody wrote about was the fact that you can remove and replace the assembly as a whole unit. So on the bench I was able to easily adjust the shoes ready for fitting.
So here is the back of the transfer box.
The mounting bolts are screwed in and there is still plenty of room to get at them with a socket. Torque them up to either 25Nm or 18 lbsft, it's the same thing.
The I fitted the drum
Once the drum was bolted on I adjusted the shoes one more quarter turn.
Then finally connected the hand brake cable to the rod and adjusted the cable to create the right amount of travel on the hand brake lever.
There you go, all done.
