rear disk brakes
« on: December 04, 2004, 07:10:33 AM »
I'm sick of wearing brake shoes out from all the river crossing I do as the small stones get in and tear them to bits so I'm going to convert mine to disk  ;D here's the hard wear to start it the project....



Solid front Escudo disk with some customized venting and 92' Nissan bluebird rear calipers with hand brake actuators.

My plan is to machine the rear drum down so I still have the studs to mount the disk on and mount the caliper off the four bolts on the end of the axle housing.

If you do a lot of river crossing then why did you get the rotors with holes in them? rocks like holes.

Some reason it's not a problem with the disk's the stones don't seem to get stuck in them  ??? With the drums once there in they don't seem to come back out.

I've run them on the front before and I have a mate with a Sammy running them on all fours corners with no problems.

That looks like an awesome project, bro!

I would love nothing more then to upgrade my rear drums to discs.  The extra stopping power and good looks are reason enough for me...just the massive cost is holding me back since I would have to get a custom shop to do it for me. :(

I think this is the way the conversion
kits are made, and for all you readers
a Nissan Bluebird is called a Maxima in
the US, a good donor for parts, as they
will be easily available at any autoparts
store no matter where you are wheeling

Ohh and if you can find the later model
rear axles, they have a flange with 5 lugs
pressed in to it, might not take as much
fabrication that way, off with the drums
and on with the disks

Hey Wild I've never noticed those 5 lug axles, I might take a look for some at the dismantlers.

I decided on Bluebird calipers after a few hours of scouring the dismantlers looking for a suitable donor.

The big problem I found is that most cars have way smaller rear disk compared to the zooks front which meant I couldn't get enough pad to cover the disk and the ones that had big rear disk ran a separate small drum hand brake inside the disk ???

Hmm, I'll have to look closley at the Maxima/Blubird
calipers, I was going to use a set of those too, tho
I was going to build a full floater rear axle from a pair
of front spindles and rotors, even use a lockout hub
for trail damage towing, or just 2 wheel street towing
like behind a motorhome or on a tow dolly.

The Bluebird is a heavy car, as small/mid size
cars go, so I'm sure there will be plenty of
stopping power in those calipers

Send Pics   :)  I'd like to see how it comes out

Gidday Shane,
I'll be keen to see how yours works out. I'm looking at using Samurai/Sierra fronts with Nissan Skyline/Pintara calipers for my conversion. I've swapped my standard lwb vented fronts for some slotted vented fronts and braided lines. Apart from the fact that drums suck I've found since swapping from OME to Calmini suspension the softer spring rate causes the nose to dive under heavy braking unweighting the rear causing it to lockup easier.

i do a lot of mud and water driving where i am. i've never had my rear brakes lock up under any situation, even off road. and now its worse, cos i dont have any rear brakes now, my drums have decided to seize and not work anymore.

i want to convert to discs, but i can't seem to get my head around the cost. i can get sierra brakes and hubs, but how will i mount them on the rear?

i've had a look at the possibilities, but either way, the best way is to get a bracket machined/made up to hold the calipers and the axle in.

can you guys, more so shane, keep us updated and also, a rough cost guide to how and what you use.

thanks

Thats basically what I was thinking too, I looked at a few Mazda 323 GT and Toyota FX Corollas ricer models which had good size disk but very small calipers so I decided a big car like the Bluebird.

CJ,
Skyline calipers won't work if you want to keep your hand brake as they have the small drum inside the disk to actuate the Handbrake, way too much work to make all that fit!. I looked at an 92ish Skyline and was eying up the four pots then discovered the drum handbrake :'(

I'm still a way off getting it running again, I've installed the Calmini 3", should be putting the 4:24's in this week (and center-force clutch from Calmini) as well as finish the rock sliders, move the winch back (as it too protrusive according to the certifier) finish the disk conversion and then wait for Calmini to send 5:83s and an Anvil over which is 4 weeks away seems they have no stock :'(

Skid,
Sierra's front calipers won't give you a hand brake option either which I need on mine to get a warrant of fitness to stay road worthy. You could use them IF you don't want a hand brake but I think even a full off roader needs one anyway.

One other option if you don't need to have a mechanical h/brake would be to put line lockers in your system, then you'd put your foot on the brake pedal pressurize the system and hit the switch. I'm going to add this system as well in mine.

Total cost of my conversion so far:
front Escudo rotors $ 30 each (all thou this is a from a mate  :-X) Rear Bluebird Calipers $30 each.

From a fabrication point of view, it only
makes sence to use a caliper with a hand
brake built in, it's a better setup too, remember
the rocks in the old drums caused problems,
what's to keep them out of the parking drums ?

The question I have is can I use the SideKick/Vitara
cables or do I need to get the Maxima/bluebird
ones and fit them to the hand brake ?
If they are longer it might work out better
for a long travel rear suspension

Shane,
The Skyline setup is what someone here is using and they offered to help me out to do mine. Haven't actually looked at them myself. hopefully I'll see him this week and find out more. I know of a Suzuki workshop here who has been using Pintara or Corolla calipers in their conversions. Going to be over your way next week and going to do some river sledging while I'm there  8)

Wild,
Either way with the cables I don't think it's going to be too bigger issue. Part of my choice with the Bluebird calipers was the fact that the ends are just a loop that fits over a hook, not to hard to fudge some thing up and get it crimped to the Escudo cables  ;)

I won't rule out using the Blue bird cables yet thou just in case as you said they could be longer.

CJ,
Let me know what/how he's running it, I'd be interested to know. Were abouts over here are you coming too, any were near me in Napier ??

I'll let you know.
Not Napier this time. Hopefully I'll be spending most of my time on a boat, maybe Great Barrier Island or the Mercury Islands. The river sledging will be on the Rangitaiki River I think, just a day trip. Next time I come down to Havelock it'd be good to meet.
