I quite agree. My landrover, my responsibility, good and bad.

Doesn't stop me asking for advice, or details, I would have thought.

Or giving advice to others, either.

[Jon White]

The one thing that you have to bear in mind is that this a public forum.

Anyone can read this, anyone can pick up the information.

I'll tell people how to do most things, but not something thats safety related.

One thing i will, and have posted in the past is how to bolt on rear disks to a series axle. Search back through my previous postings and you'll see that a rear conversion is more or less a nuts and bolts job. Its the front end thats tricky to make.

Those wilwood calipers look fantastic. Almost too nice for a landrover, still, if they do the job....

Which Toyota were those discs fitted to? I might get a pair and see how the setup would look.

I agree it is a public forum. Its a good forum if your in to Land Rovers.
There is alot more imformation out there and not Land Rover orientated.
But by enlarge the public do not act on it, just as well too!!!!!!!
I do not mind asking for advise and when it is recieved its entirely up to me if I act on it.
Again I would like to thank you guys who have been their and done it and can offer some advise.
This is my final post on this (no point in beating a dead horse to death).

I second both Jon and Tonks comments, but I made mine in the shed with a large pillar drill and a small lathe.

Its not rocket science but you do need to be careful.

I used a pointer to centre the discs on the hubs and to check run out, my final solution used discovery rear calipers and worked well.

You do need to uprate the servo and I wouldn't have done it without a dual master cylinder.

I didn't do the rears but was only runnind a 2.25 petrol so power wasn't a problem.

Its doable with care and time without a lot of expensive engineering equipment, but it would make it easier and quicker.

I reckon I spent a couple of weeks in trying it all out and making it then a couple of days in fitting and fettling.

Do you mind if I ask you which discs you used? I'd appreciate it if you would tell me.

Not personally attacking people. but bear in mind this is then SVA and Q plate teritory, as the vehicle would no longer retain original type chassis and/or the original chassis has been substancially modified.

the dvla system runs a points system for modified vehicles
if you modify a vehicle u need to retain 8 points to retain the reg
here are the points:
Chassis: 5
Gearbox: 2
Axles: 2
Suspension: 2
Steering: 2
Engine: 1

to retain the reg you could change everithing but the engine, chassis and one other component... i would think the suspension mounts are classed in the suspension section really because although your changing a part of the chassis it is only a bracket or eight and i cant really see how ou could change any of the other components without chassis bracket mods

Great informative post
good job well done
keep it up
i think we need one on coverting to rr axles...well i know i do haha

[Gazzar]

Ah, yes, I remember that from my Kit car days - before the SVA.

Where I am living at the moment rules are different.

The chassis determines the vehicle. Change the chassis and you change the age and plate. So if you rechassis your 1959 swb with a new chassis it becomes a 2008 (or whatever), that is, if you tell them.

They couldn't give a damn what else you do - except if you change the engine size to a bigger engine you pay more road tax. If you tell them.

Of course you have to do a safety test every now and then, and also your insurance company must know of all changes, but other than that you can do what you like.

Even the safety test is no longer required after 30 years (I actually find this frightening) but most insurance companies would insist on an engineer/garage report before gining cover.

Actually there are moves afot to "Harmonise" the UK rules - so that no non-manufaturer mods are allowed.

<>Soap box time<>

Lobby your MP and MEP about this - make it a big issue, otherwise you'll lose the right to build your own vehicle the way you like it. Quick email should do it, or perhaps a petition online?

Sorry,
UK I believe if you change the chassis for a brand new one of the same type then you retain reg.
Second hand chassis Q reg.
Alter the suspension mounts on the chassis (coiler) Q reg.
There are plenty of SVA threads in this subject on the forum if you want to find out.

[Gazzar]

Ah, Marc, you are right, but I don't live in the UK.

My point is that you guys in the UK have some very flexible rules at the moment - and unless you continue to lobby for those rules to be preserved they will be taken away.

As I understand it the UK Govt are actively considering implementing an EU directive that will take these rules away. It will get to the stage where the major manufacurers have the whole thing wrapped up.

Amongst the current proposals is a requirement that all new vehicles will have to have ABS certified by the mannufacturer.

So - no more road legal one offs, for starters. No more kit cars.

Next: no new chassis modifications unless certified by manufaturer.

Also: no tyres that were not originally specified by the manufacturer.

Whats next? All vehicles over 30 years to be restricted to 500 km per annum? Or scrapped unless of special historical interest?

Variations of these rules are alreay in place in some parts of the world.

Point 1 - yes, point 2 - yes

The rest is a choice, discs and calipers, tonk can answer better as his brackets are simpler so they might suit your quest better. What i can tell you from my experiance is that a flat bracket will work with a lower hat area for the disc and smaller calipers or sliding calipers, using rover calipers will need 1" spacers at the hub/wheel.

Grem

So then since I have wheels that sit 1" further out than stock wheels, Rangie calipers would work? I am soon going to have a spare pair off of an '87, but they are the fronts. Are the fronts much if any larger than the rear calipers? I need extra stopping power since I have extra horsepower. I currently have 110 rear drums up front, so I could either move them to the back or put discs on back as well.

You mean offset or spacers?? Wheel offset does not effect the caliper as the monting face of the wheel is still at the hub, i you do it the way i did rangie calipers should fit with out problems, its according to what disc offset you use. If you use a lower hat area and rover calipers you will defenitly need spacers, or thats what i found out.

Fronts on a rangie or any rover are 4 pot calipers while the rears are 2 pot, so physically the fronts are always larger. Discs at the rear is a bolt on job to be tackled soon.

Being in the US i think you might be better off searching for another caliper other than a rover!

Hi there, I've been trying to find a link to the rear disc brake conversion but I can't find one that works, can anyone help?

one of the land rover mags did an article a while back
a 2nd hand chassis to the same spec as original is classed as the same chassis therefore you still got those 5 points
but the suspension mounts are in a grey area but surely if you are changing the suspension the mounts will be different and the rest of the chassis unaltered...mind you everything on the points system requires chassis mount changes unless to the original dimensions...so surely the mounts are classed with the item be it suspension or whatever

The one i found was for a 110 axle, but its reletively the same process, or similar. Its in the tech section on this board.

Any news on those Toyota disks???

I'd love to put disks on my series 2A. I have a stage 1 front axle waiting for it and hopefully a V8 engine to suit

I already have a late series 3 dual circuit servo master cylinder fitted, will that be OK running front disks?

Cheers,

[Gazzar]

Hi Henrycrabbe.

What I suggest is you go down to a good motor factor (ask local mechanics and see where they go).

Ask the parts guy for a copy of the Delphi brake parts book. My Factor gave me one - said they were for customers!

Its about 1000 pages thick, but towards the back there is a disk brake reverse lookup where the dimensions of each brake are set out.

To reuse landrover callipers you need a disk that is about the same diamater (298mm or so).

My research showed a small number of disks with a lower top hat than land rover: a Nissan Patrol, some Porsche and some Toyota Landcruser/Hi lux.

Of course I may be reading the book wrong so what I'm going to do is ask my local mechanic to get a second hand set of disks for me and I'll work from there.

Remember - brakes are serious, eve if you are a land rover brake engineer with access to the full brake testing regime and certification process any modifications you do are unapproved, dangerous and uninsured. Bring it to a main dealer for any safety critical work.

G.

[Tonk]

or look through here

[henrycrabbe]

Thanks for the info, I'll see what I can find.

I work in the automotive manufacturing industry, previously on production line test equipment (wheel alignment & roll test) now on robotic welders etc. so I know the trouble the manufacturers go to (or not ) to get a parts just right. As I see it as long as you use a disk from an equivalent type or weight of vehicle and bolt it to the hub with the right size and type of bolts determined by...

hit wrong button there!

Where's edit - Oh here we go...

...what LR used on the defender etc. then you shouldn't have any problems. That only leaves the caliper choice and the mounting bracket. A bracket made out of 10mm steel plate is going to be stronger than the cast lugs on the RR swivel housing so no problems there & 110 calipers are well up to the job if not a little OTT. I like the simplicity of those willwood calipers, which ones are they?

Thanks again,

(pressing the right buttons but not necessarily in the right order )

Hello Gremlin; I'm struggling with a conversion kit out of South Africa. Could you please forward the drawing/dimensions of the backplate? wellpath@gmail.com. Thanks: Roland Netherlands
