Rear Swaybar & Read Disc Brakes
Hey guys,
I did a search on rear swaybar and nothing came up - thought I might ask the obvious quesiton.
It appears none of the Australian cars came delivered with rear disc brakes - Do we / Does anyone know if the same can be said with a factory fit rear swaybar?
I've come accross some factory tech drawings in one of the manuals outlining the Remove and Replace procedure for a rear swaybat, however can't find any evidence these were ever offered on an Australian car...
Thanks in advance!
not quite right (rear disks / sway bar)
ok, here's an overview and why it stopped me about a year ago:
rear disks go like this:
same master cylinder and ABS module -
same brake piping to the outsides of the rear axle
same axles
WIN!
backing plates are unique
disks are unique but very very close to ES VRX 5 stud hats (maybe a conversion?) but VRX calipers are heaps bigger and run biger pads - no good :(
rear calipers are on _some_ pintara's but not in australia
rear pads are from some 4cyl magna's (rare)
hand brake cables are unique.
rear shoe arms and levers are unique
BOOO
disks/inner shoes/calipers/pads are all available off UK ebay or second hand from German wreckers
I have tried for the last 4 years to convince german breakers to seperate a rear axle housing for me and just ship brakes and backing plates but no go.
I ran all itemised part numbers through a JAP mitsu parts dealer via an ilegal jap-based drift parts importer and all items are available EXCEPT backing plates and hand brake cables are available.
last chance was to see if a VRX ES lancer rear brake backing plate would mount to our axle tube BUT from photos it appears that the bolt spacing is different and as a VRX has rear struts, not a live axle, the rear wheel bearing and ABS pickup gets in the way
given the drums for the handbrake in standard OZ io's is poor anyway, and the rear disks use a mini drum system for the handbrake (and handbrakes are used a lo 4wd'ing) i couldn't see any reason to go ahead with a conversion unless I started track-racing my Io
rear sway bar goes like this:
see the two bolt holes about 1" appart in the rear chasis rails halfway between the back of the bumper and the axle, (your towbar is probably going through the rear pair) these are used for the rear sway bar: a "U" bracket bolts to the chasis using 4 bolts per side (we don't have the captive nuts in our rails to use properly) attached to the bottom of this bracket is an "n" shape that points down - this recieves the sway bar link that has a bush on the top like a rear suspension arm but thinner.
sway bar bolts to the rear axle on custom factory welded plates (we don't get them here on OZ io's) and attaches to the bottom of the drop links with ball joints - see below:
OK - I have run ALL part numbers through mitsu here and also throught the underground illeagal jap importer and the only parts you can get are:
bolts (standard)
ball joints (standard)
heavy duty sway bar (aftermarket)
that's it!
I have been watching a pair of used chasis mounts for a year now from a german breaker who would not pull the sway bar from the rear axle housing, late last night a complete sway bar came on ebay .de with the drop links.
$140 total price including postage to my german mail redirect box.
Once it arrives I'l hit the chasis mounts with a grinder to get them to fit around my towbar
I'll hit up K-Mac for some universal rear sway bar mounts (giant "U" brackets that go around your rear axle tube) and see how it all fits in.
I do a lot of highway driving and the back of my Io has always wobbled on bumps in corners - shit's me no end, also I live atop a mountain with windy roads and have longed for more control.
will post up pics as I go.
car wobble
My car used to loose rear traction going a bit sideway by "jumping' on a curved and uneven road at faster speed (when I push it a bit), is it what yours does ? They fitted new rear suspension and told me to lower the tyre pressure to 30 psi (I used to get them at 36psi)...it is great now.
I'd like to believe...
the problem to be more one of lifting the inside rear wheel in a turn and the subsequent loss of traction - very noticeable if you don't have the rear LSD option.
In normal road use it's more of an annoyance than anything else, and the driver can compensate by simply backing off the throttle (there's no loss of control or stability, at least not in my experience), but in competitive driving the ability to get on the power earlier can make a signficant difference to the results.
Oh - by the way - 30 psi is still a little on the high side, tire placard on mine calls for 1.8 bar, around 26 psi.
no the case
OK,
what I am getting is on long corners on motorways or 80km/h + roads, mid-way through the corner the body is leaning (this is normal) and you hit a bump, this causes the body to rock further over and subsequently causes a wobble as the increased lateral compression changes the rear axle alignment and the front steering geometry, the body roll rock and the momentary alignment change cause the car to roll again and a wobble is set up.
tyre PSI is typically 28psi, i find 26 leaves my sidewalls on the ground on corners up here.
new shocks simply increased the speed at which this happens - was 70km/h,now 80km/h. I think the fact it is a SWB and the wheelbase is shorter will have impact on the situation.
*note, I find the power from the io is such that on the "rear-axle-wind-up" scenario Fordem and pajero io talk about rarely happens as you can either back off to stop it, or floor it to fully break traction and drift the corner.
yes
I have a swb, and it was doing what you describe. Going fine in the long curve, as soon as the car hit a small bump, it made several little jump going sideways a little but not sliding, just bouncing. I looked at my paper work, they say that the rear spring were too soft and that the "on the way out" shock not controlling the spring. They not only replaced the shock but got new heavier custom spring made. The springs costed $315, shock $280 and $150 for labour. The front have been done before and the car leaning is nearly not there anymore, and no more bouncing and much better handling.
I find that 26 psi would damage my yokohama edges very quickly (less than 25000km). Tyre placard are too expensive to follow.
Thanks Bob for the info -
Thanks Bob for the info - Seems like you've spent a decent chunk of time collecting it all... I might bug you for some of those part numbers at some point and will be interested to see how you go with your German Ebay purchase too!
For fitment to mine, there won't be any tow bar and fitting the captive nuts to the chassis isn't an issue either. I would normally custom fab something special up and do it from scratch, but given I'm preparing for production class I need to keep it as OEM as possible..
parts catalogue
I put this as a bookmark on my phone - helps with sleepless nights. There are loads of catalogues out there but this one has really good pics!
http://www.auto-parts.spb.ru/cat/mi/mi2.mycat
you'll find the io hidden under both pajero io, montero io and pajero pinin.
interesting varieties are the 2003+ pinin's with the GDI autobahn rear disks and roll bars (but crazy lowered) and the hongkong turbo auto's.
follow the breakdown in the pics and the final link shows part number and russian availability - google part number to find an online supplier.
If I see another one come up I'll PM you but i've been waiting years and this is the first so far. I hope for your sake it won't fit my SWB as it is only meant for a LWB ;)
Cheers for that - I'm in NZ
Cheers for that - I'm in NZ on business this week so light up for wifi and data - Will be sure to take a closer look once I'm back home in OZ.
No stress with what you've got coming - You've been on the war path much longer than me, happy to get inline! ;-)
I like it! Will be
I like it!
Will be interesting to see that fit up under there and see what needs to be done.
I've done nothing to mine other than shop for parts. Car is still in VIC and I won't be down there for atleast another month or so. Have 'Other' toys here in Sydney to keep me busy though...
Will keep an eye out for the INSTALLED pics! ;-)
Ha - Kev at KMAC is always
Ha - Kev at KMAC is always good value for a chat!
I'm not sure there is much volume to convince him, but if anyone who does swaybars will do it - It will be him. I know some others that will copy them for us if we need at a price, however I'm not sure they could be convinced to jig them up for ongoing orders where as Kev might.

I haven't seen a rear sway bar....I think that there is 2 types of front sway bar, one being thicker than the other. The car being that light you might get away with heavy spring and shock instead....this said my rally driving is limited to the passenger seat :)
if you find a way of getting the rear fitted with rear disc brake, I would be interested to fit some on my io. The drum are a pain and need adjusting often, not mentioning the cleaning after a mud bath....
I have reply to your PM regarding the head rest.
Happy io
My io is now SOLD Thankshttp://pajerio.com/forum/claudes-io-2002-zr-built-thread-onlyhappy-io
