Need caliper suggestions

[De-Ranged]

I'm trying to sort a disk conversion for a Series Landrover problem is there isn't enough room for the caliper I'd like to run
I need a decent size front caliper that has the mounting lugs at each end not on the side sticking down

Any suggestions

[oldblue]

Years ago, I made disk brake conversions for early Landrovers.
I was using EE80, EE90 Toyota Carola callipers, with my own designed mounting Bkts and made my own Discs Rotors to suit.
It was the only calliper the was small enough to allow you to fit genuine Landrover 16" wheels.

[De-Ranged]

Don't know if they would pass the LVVTA brake test in a 109" with 32"s and a big heavy motor/trans, from memory they arn't a big caliper... I might be wrong, the E90 was the one with the charged 4age? been a few years since I was a boy racers lol, will check them out, thank you
I've found a couple of conversions on the net.... one in Aus used a modified vented disk and willwood calipers, all bolt on but at $5000 I think is a bit much lol
I've found some others UK/Europe that have there own cast swivel housing and hub, a bit more work than I was anticipating

Will see how it goes....

If the weather holds I'll go for a wonder through a couple of wreckers later this week

Well way I see it.... you're a clever barstard and you'll find a way. .to make it work

I have two Landrover axles with a disc conversion already done, what they are from, I don't know, what they used, I don't know, what axles are they - Land Rover and they have been beefed up. Next time I am at the shed I will look and take some photo's for you Reece...

toyoya supra/soarer or 4 pot nissan skyline calipers should work as the early to mid 90's 6 cylinder cars had big brakes but only 15 or 16 inch rims.

don't know about the yota ones but nissan, you didnt have to unbolt anything to change the pads, two pins and they slide out

[S1V8]

been running discs in the front since the 80's using Toyota corolla calipers and racing pads around $160 a set no problems also depends on what sort of booster you use.Running 5 litre with Ford 9" in back and have no problem stopping,all cert and street legal.

[oldblue]

A lot depends on the type of brake pads you use, I found that a soft Bendix XP Grade gave the best bite when cold.( This was 30 years ago ).

[Jafa]

Its a Landy.. wont you be just tightening a leather strap around the drive shaft or some other horse drawn cart inspired system?...

or go really hi tech...


Sorry, not being much help am I Reece, you can tell me to f@rk off anytime

[De-Ranged]

all good jafa


A little background and stats to help put this in place
I am planing on fitting a TD42turbo into a series 2 109"
Starting with the motor the TD motor is 106Kw vs the biggest motor that came out in the landy the 3.5l V8 at 68Kw so a 50% increase in power, the weight increase is near on twice the weight of the alloy V8 the auto trans well its easily twice the weight again lol so going to need a brake upgrade
From the technical handbook (builders cert rules), the truck is sitting in the Heavy weight class 1500+kgs the recommendations for this are for under 300hp a 280dia x 25mm vented disk and med single or double pot caliper
the next one up is 300dia x 28mm vented disk and med 4 pot caliper+
The reason I have listed the next setting is I want to get it certed on 33"s (larger rolling mass is alot harder to stop)
add to this cert thresholds are changing, I have done stuff that has easily pass'd in the past that wont pass now
One change is welding... if its fab'd its alot harder to get things approved (and expensive)

Given my measurements give me a disk that is a little over 280 in dia, I want grunty 4 pot calipers
Will check out the Nissans on thurs
I might have an answer on how to fit the Toyota IFS calipers (a pic would have helped but I left the camera at the shed lol) was looking at a caliper thinking over all the cars I've been under trying to visualize the calipers when I noticed the bolts that bolt the two halves of the caliper together 4 x M10 bolts and they are out on the ends, now the normal caliper mounting bolts are 2 x M12, some simple math and if I was to bolt the caliper together with a mount using the 4 M10's I have almost 50% more and it would allow me to cut the tabs off the base of the caliper allowing it to fit
Now I know some race setups use a system like this to mount the caliper but has anyone heard of it being certed ?

Oh and the best pads I've found are the cheapest ones at BNT they don't last but they seem to grab the best cold, but if they don't work I'll remember those ones OB thanks

TD42 Surely there is a motor better suited for a rover than one of them, no denying they are a great motor but they are a truck motor designed for a truck. I mean a 1KZ is pretty much the same KW but it's about 100kgs lighter, not to mention a 4 cylinder so easier to squeeze in. Don't get me wrong, with your level of skill I'm sure you can easily make a TD42 work it just doesn't sound like the best choice?

[Rotazuk]

I managed to squeeze mazda rx7 calipers on the 4x4 I built . It was suzuki based thou so the diffs would have been smaller to start with . I did get them to fit under 15" rims . On the RX7 they are on 280mm disc's . I picked these as they were one of a few calipers that would fit on a GV disc , ie 22mm wide . Not quite side mounted thou .




A couple of other options I looked at were side mounted but at the time were for a different thickness disc (25mm) so I did not go with them . In hind sight for a non road legal truck a 22mm disc would have worked just fine I expect .

[muddymatt1973]

Maybe I'm missing something but why not just roll a pair of Discovery or Rangie axels under it? Then you have great brakes - clearance for 15's - correct front/rear brake balance and easy parts availability.

[De-Ranged]

Yea I know Kw's vs size I'm better with a 1kz.... torque on the other hand and this is going to be the tow wagon for the toy add to this, because of the over engineering on these motors they are super reliable

RZ could you take a photo of the front calipers with a tape measure beside them... the back axle disks are easy, its the swivel housing on the front axle that is causing the space issue

MM Yea na lol, the landy is leaf sprung and those axles are coil sprung.... this means I'm looking at having to build some sort of bolt on arms for the steering.... this would add alot more problems to the cert than squeezing disks in there, also this could be enough to bump me into a full scratch built

[derk]

somehow I think throwing an old landy body on a Saf chassis with a TD42 and disc's all round isn't going to be an option

[zukmeista]

I see. If you're towing with it then TD42 all the way, no cracked heads at least. Wonder how the rover diffs will go with a torque monster TD42 combined with towing... Will it have a auto or manual behind it, assuming you are using safari box and transfer?

[De-Ranged]

D the body swop idea again sound simple but has its catches, engine bay is too big and the motor is too far forward to fit the SII body I'd have to go to a Defender next your brake master is way to big to fit under the landy bonnet, yes the gains would be better, suspension disk brakes, possibly aircon even lol but I think it would be alot more work
And you'll laugh at this... it wouldn't be a landy lol

Z Its the nissan auto and as far as towing goes there is no stress at all rear axle is Salsbery a Dana 60 copy.... front end lol yea not so good but as its going to be a shinny I shouldn't be putting it into stuff that will eat the axles

[Crash bandicoot]

The way this is going, Just stick the L/R badge on a patrol.

[derk]

are you going to build a shorty or a 109" for a tow wagon

[zukmeista]

are you going to build a shorty or a 109" for a tow wagon

I am planing on fitting a TD42turbo into a series 2 109"

Don't know if they would pass the LVVTA brake test in a 109" with 32"s

[derk]

sweet mate shows how much attention I pay

[De-Ranged]

Here's the pic of the caliper so you guys can see what I'm up too


It can't fit in next to the swivel housing due to the mounting posts being too tall... they need to be at least 10mm shorter

My answer is to cut them off and mount off the 4 caliper joining bolts... not the easiest mounting but it lets me run a caliper that I know passes cert for a hilux on 35"s

[Rotazuk]

Whats the distance between the mount bolts , that you are going to cut off ?

[De-Ranged]

Right got a chance to talk to the certifier lol that was a brick wall
There is a minim mounting bolt size... that doesn't take into account the number of bolts your using so back to the drawing board lol

RZ Could I grab some dimensions off you for those RX7 calipers
text me on o27 541 8794 and I'll call ya

Mitsubishi GTO, Mazda RX7 and Subaru have a similar caliper, but different mounts. In pics they appear further apart- maybe this will allow it to sit closer in to swivel hub?
Check pics in links for ideas;

If they look like they could work maybe track some down locally and measure up.

[De-Ranged]

Thanks for the suggestions, have a mate with a subby so thats an easy one

[Rotazuk]

These are just rough measurements taken with the wheel on . To get any deep i will need to take the wheel off , however I expect these will be enough to rule them in or out .



The bulk of the caliper is 70 x 210 mm . There is 115 mm at the centre line between bolt holes ( prob 120 but not precise measurements ) . The mount holes are 165mm apart and seem to stick down from the main caliper by 40mm .

They are ment for a disc 285 dia and 22mm . Not a good match for a landie , seems to be 24 mm .

Good site to check out brake stuff , and all pic's

Mate It fits with room to spare, all I need is the depth so center line on the caliper and tab mounting faces and over all depth, these let me play with disk options, from your measurements I could get this under a 15" rim with a bit under 300mm dia disk (final measure will depend on pad placement)
The catch now and why I need depth is the caliper mounting plate has to fit between the swivel housing and the disk hat, the further out this has to move the tighter this is

Oh and for reference since your doing this sort of thing search DBA disks they have a real good PDF catalog that has almost all the disk dimensions listed for all they make.... they just don't have the "hat" dia but it will give you a list of possibilities

[oldblue]

Just a thought, when I was making conversions for Landrovers I made a wooden pattern with relief's ( for removing pattern from the sand box) plus allowing for shrinkage of the cast iron.
By doing this it gave me a way to build all of parameter's that were needed. These disc's were bolted x 5 to the back of the hub, after the hub had been machined to a flat surface.

[Rotazuk]

And close up of mount tab



Sorry forgot , mount tab is 18mm thick . There is what looks like a washer between my bracket and the mount tab , this is the mount tab . probably could be machined off if you need a few more mm .

Now 68 + 68 does not equal the 135 I got for overall width . Also the mazda name sits proud , up to 6mm and the overall width does not count the hose fitting .

You can see I could have taken about 5mm of the disc and moved the caliper closer in to the center , this would increase the clearance to the rim . I have about 2mm now , so next time I will skim the disc down a bit .

Yeh , have a copy of the DBA catalouge . Was looking throu the other site as it lists the piston and pad sizes for all the brakes too . Without going custom discs this is all I could get to work . It worked out well for me , I was lucky .
