Interesting find Shayne, but I can't see how they would help

That is a nice find but its the KZN185 thats the "same" as the collie so not sure if they would fit. But I wouldn't mine some if they did.

I'm the first to admit i don't know what i'm talking about but if the problem is caused by axle flex and most on here are running bigger springs i thought perhaps a longer shaft might sort of relieve the as yet unidentified stress that causes the handbrake to fail .

I think I linked to wither that one or the same one on a different site but as above I was worried that as it is for the KZN135 not sure if it would be a direct fit.

Don't worry about thinking you don't know what your talking about mate. The 90 and most other LC's have a solid rear axle. Those halfshafts are for the front end IFS and are something I have not been able to source for the right source of money. You never know when some of your ideas might come in handy even if not the this particular issue.

Ah OK, I'm with you now That is a front drive shaft for a vehicle with independent front suspension IFS. The rear axle on all Land Cruisers is a solid axle, what is called a live axle and this is where the problem with the hand brake starts. If the rear suspension was also IFS I suspect we would not be having this conversation. Maybe we should all sell up and buy ourselves a newer shape Shogun with all round IFS

Cheers for that chris , i realize i'm like a dog with a bone that wont let go but when something interests me i tend to use it to educate myself a bit and i'm desperately lacking in knowledge when it comes to 4 wheels .

Well you came to the right place then mate. I have learned so much over the years, and I am sure I asked some dumb questions at the start and probably still do (Brake warning light comes to mind)

 

[Shayne]

Theres your answer then sae70 split the rear shaft so it has a bit of give to compensate for the greater axle travel that results from a suspension lift ?

Nah that comes from over thinking a problem , i had to remind myself constantly when working on my bikes , check AIR , FUEL and SPARK in that order every time , simplest possibility first or you will have the whole engine out before you realize you only had to turn a screw !

Here's a couple of pics of the Rover caliper







No idea if it would work without oil in it except that the MOT calls for a mechanical solution to the hand brake so the cam must operate some kind of plunger that physically pushes the piston out and if this is so then oil/grease may be required for lubrication.

Seeing these photos reminds me that when you go to get your second hand calipers for around £20/£30 you will also need the bracket that the hand brake cable outer attaches to as it's a separate part

Another interesting point about the Suzuki Vitara hand brake is that it is indeed a dual cable set up. Each cable running from the rear of the hand brake out to the rear of each drum and then entering the drum and directly attaching to the operating lever on one of the shoes. The cables do not touch the rear axle except at the drum and are held to the underside of the bodywork with a couple of clamps that we all removed following lifting to allow the cables to move freely, so they had plenty of slack.

I went back to my old Suzuki forum and had a good search for hand brake issues as I couldn't really remember it being an issue for me in the same way the Land Cruiser hand brake is and can report that I over more than 5 years of ownership and two vehicles never reported and or moaned about having to constantly adjust the hand brake. So I did a general hand brake search on the forum and again found very little to support there being anything like the same issues that we Toyota owners have and can only put this down to the design of the system. When you look at the Toyota hand brake set up compared to the Suzuki one it does seem to be a little over engineered in comparison and for once not in a good way!!!!

That kind of harks back to what I was saying earlier about using the HB cable setup from a Rav4. Especially for me and you steven, not sure if a straight swap would be feesible on other trucks but I do think that the sizes of the 90 and the rav maybe close enough to try. Might be worth a try as it should reduce /eliminate the movement from getting all twisty.

I wonder, if you removed the HB cable after adjusting, before going off road and then replaced it with no other adjustments would it be fine? Does it seem to be that the cable is being pulled and stretched is various directions.

Some decent finds there chaps. I like the spot handbrake caliper. Hmm. Tidy. Can't see how it fixes though. Yep some good ideas and some barking nonsense too. Keep it up chaps.

There are sort of two build threads going here. Original isn't mine I know but we're working towards a similar goal. But can we forget the MOT? We know, WE KNOW. The way I am looking at a prop brake means that we could have the same basic build but mine would be air operated cable and NOT part of the MOT as I am keeping the existing brake and for the Colorado it could be lever cable operated - utilising the current handbrake lever which would then BE part of the MOT. All we need is a suitable, compact and cheap caliper that operates by cable. Of which there seem to be a few around.

The Jag XJ's had a seperate handbrake caliper http://www.ebay.co.uk/sch/i.html?_n...dkw=jag+handbrake+caliper&_osacat=0&_from=R40

 

[Chris]

Hmm, bit open and exposed that one Andy. Something a little more modern and sealed would be better. I might try and track down one of those ones you posted earlier.

The one on ebay looks expensive, try http://www.rallydesign.co.uk/product_info.php?products_id=8312

 

[Chris]

Ha ha, I'm ahead of you Andy. Already looking. And they have brackets too. That price is plus VAT though

They're good, I like those

A dedicated hand brake caliper



I wonder how many other exist out there

interesting read perhaps

Is it worth moving this thread to the modifications section and starting a new "Improving the existing handbrake setup" thread in the 90 series section???
