I got a set of Jap front brake system for AE86..
does anyone know any calipers can fit the JAP ae86 brake for upgrade?
i want some 4 pots or 2 pots that put into the JAP86 fron disk.

Hi,
I am not sure what jap brakes you have, but i use RX7 series 5 or 6 calipers on my ae86. They are 4 pot and big.

The calipers mount on AE86 vented disk rotor are the same as solid rotor type. (Although I have heard a rumor there are two types of caliper mounts) anywho, if there was a simple / relatively simple upgrade that only involved the caliper, people would have already done so.
One only option are to use the jap vented disc and say nissan 4 spot calipers inc adapter bracket if they fit or buy something like Terry O'bierne is selling: a full 4 spot kit inc disc, caliper and mod mount.
However, there maybe somebody who has done a conversion, but I feel like it would involve a spacer/adapter.
It should be noted that MotoP on club4ag used factory vented brakes on his blacktop car. Good brake pads make all the difference. Don't use really hard pads like Endless or race pads: they will chew your rotor, try EBC green or kevlar. The same pad for solid disc brakes as for the vented.

Hay Jaz
Your probably right about there being 2 different mounts,
I have 2 Sets of spare Vented Disk Calipers, both of them are identical except their mounting holes are different (Slightly further apart) , and they have different Model numbers on them 
But their is probably another toyota model out there that uses Sprinter Pads.
I will do some reaserch later tonight.
I only Use Standard Disks front and rear on my rally car with upgraded Pads and it stops on a dime.

idfamily,
Call IDB Automotive in Melb on (03) 94285446 they make brake coversion kits to suit the ae86. They might be able to help you with calipers.

yeah, you could call IDB, or you can not get ripped off, save your money and spent it more wisely... ask around with who's in the know and see if you can it get done elsewhere, or even yourself... brake upgrades are rarely difficult and done wisely don't have to be all that expensive either.
IDB do nice work, don't get me wrong, but their work comes at a premium price, and if you ever saw their workshop, you'd never leave your car with them... but never the less, if you are interested, you could call and get a price... i think they want like $900 for twin piston and over $1500 for a four piston kit... just to compare, i recently done a 4 piston job on my celica, included reco calipers, brand new vented and slotted discs, new master cylinder, etc, and i spent just a fraction over $900. all done my self, all parts new or reco...

Not all of us possess the mechanical abilities do our own brake upgrades. Everything comes at a price. The person who engineered my car recommended IDB because of there good work.
When i got my brakes, it was a simple bolt on. I didn't have to pissfart around looking for parts. Also don't forget that ae86 parts are rare so extra work has to be done to make other parts fit. The rotors are 11 inch vented and slotted with huge 4 pot calipers. I have a 1g-gte in my ae86 so anything smaller would have fried under stress.
Obviously, if you can do it yourself and you have the time go for it!

Yeah i got my kit from IDB. It cost me $1800 and it doesn't include a bigger master cylinder. The parts used are from an RX7 series 6. They use an adapter and re-machine the parts to suit the ae86 struts. They're fairly big, 14 inch wheels don't fit on my car.
I know its a rip off, but i had no other options 2 years ago. I didn't know toymods existed.
BTW, i am looking to replace my master cylinder to accomodate my brakes. What do you recommend?

I have done some brake research:
The brake caliper and pad for the AE86 is unique (excpt KE71 panel van which has the same rotor and caliper as the sprinter).
There are no pads available for other cars that go into AE86 but there are good pads available. I have some Endless pads, but will not use them due to their harshness on rotors but do have EBC KEVLAR pads. They are just below EBC green stuff. They worked great with solid rotor but did produce alot of brake dust, but there is a trade off for everything. Considering the cost $75, its well worth it.
If you are insane and like to waste money (and rotor's) try Endless, Pagid, Lockheed, APRacing, and many other pads. All the big companies still make pads for AE86 as they still race/rally them all over the world.

for the neatest finish, have your current master cylinder rebored to a bigger size... i'd say 15/16" or 1"... this is the easiest and probably the cheapest... you could look around to find a replacement off another car. this is also a good option but there are two thing that you must be especially cautious of...
the depth from the back of the master cylinder to the piston must match up... if not then the piston will be either slightly depressed when the pedal is up, or vise versa where the pedal will have to travel a short distance before the rod picks up on the end of the piston, the first causing the brakes to not properly release, and the later causing there to be an 'idle' pedal movement before braking occurs. modifications can be made to the rod from the pedal to counter this, but this is quite a hassle.
the other problem is making all the brake lines match up to the new master cylinder... this is not difficult, but may require the rebending of brake pipes (highly un-reccomended) or the fabrication of new and freshly bent pipes (further cost)
so my reccomendation is to have your current master modified... to give you some idea, mine cos $203 to have done from 13/16" to 15/16"...

for a choice of larger brake master cylinders, ther probably isnt a large choice, as the four mounting points that go through the firewall and hold the cylinder to it are closer together that current toyota setups.
the only solution i could find was to redrill the mounting holes larger to suit a ae92 levin and then strengthen the firewall. it may not have been necessary and was a bit of a gamble, but 3000km later everything still is working perfectly. and only one small section of brake line had to be made.
ill see if i can take a pic and post it this afternoon.

IDB Automotive in Melb............i think is a bit too much for me..quite expensive..
i checked already.
But actually... for Orginal AE86(4AC) brake..
would it be possible to find EBC brake pad/
?
i am now using Bendix... SUX>..
during downhill.... when nearly ..finish the route..
the brake over heat!!

that's right... with IDB being so expensive and not much else that will bolt up, maybe you could look at getting some AE86 twin cam import brakes??? otherwise it's a full custom (over $1000) job...
sorry i cannot otherwise help you...

Dorikin,
Explain to me like i am a three year old, what's involved in a rebore of the master cylinder. I've gone to check out some brakes places and when i ask them about reboring the master cylinder, they look at me like as if i am from another planet!
cheers

Yeeehah,
a rebore is just like having you current master cylinder reconditioned, except when it comes back, it's bigger!!!
quite often a reconditioned master cylinder will have been resleeved... that is the inside surface of the clyinder where the piston slides is so badly worn that a simple hone (light linish of the surface by removing only a bee's dick of material) will not adequatly clean the surface of the damage (may be damage due to water, scoring, etc) so instead they bore out the cylinder and insert a sleeve that has the same internal dimentions as the original master cylinder. the reason this is so important is that in a master cylinder it's all about the condition of the bore, not the piston as the seals actually slide and seal against the bore, not the piston (it's opposite for brake calipers, but that's a slightly different issue at the moment)
now the idea a reboring the master cylinder to increase the diameter of the bore is a very good idea. as you can imagine, for a conversion, if all the external dimentions of the master cylinder remain as they were intended from the factory, there are no concerns with additional modifications when refitting the "reconditioned" master cylinder.
now before the actual cylinder bore can be machined to a greater internal dimention, there first must be available an adequate piston to suit the application... without this availability a new custom piston will need to be machined - as well as the matching seals to fit the piston (this incurs further cost - and where it becomes into serious money spending) so with an adequate piston and seals available the bore is machined out and the new piston and seal fitted... it's actually a very straight forward operation otherwise.
the importance of finding an appropriate piston is not just about the diameter of the piston. there are clearance dimentions associated with the back of the piston and where it meets the rod that pushes it from the booster. if the depth of the recess that this rod sits against is not exactly correct then one of two things will occur. if the recess is too shallow then the rod will always have pressure against it and may mean that the piston will not return back completely and can lead to the brakes not releasing... if the recess is too deep then there will be too much pedal travel before the piston in the master clyinder moves and braking begins...
now don't ask me what 15/16' piston was used in my TA22 master cylinder as i simply don't know. they went to 15/16' size as there was a piston available to suit, not needing to custom fabricate a new piston. i sent the master cylinder off to ABS in airport west (Melbourne) and it came back the next day all new and finished (they even nickle plated the housing - looks sweet)... that's all i can think of for now... well worth it it think for $200 odd
i hope i kept it simple enough, sorry if i haven't, just ask and i'll clarify. don't be afraid of brake places that don't know what this operation is about, just walk away... somone who knows what this is all about will know right away...
if it comes to the point where you cannot find any help at all, i'll offer to arrange to have your master cylinder (sprinter i think???) modified where mine was and we'll arrange delivery...
catch...

Dorikin,
Sounds like you can do a master cyl rebore backwards and 360 inverted in a triple pike!
You actually explained it to me like i am a 2 year old, buts that's cool.
Anyway, it doesn't seem like there is anyone in canberra who can do the work. I'm gunna do a little more searching, otherwise i might have to take you up that offer.
Have you got a PH NO. for ABS?
Thanx for all your help.

Yeehah
ABS is like a chain of outlets, they are all over melbourne... but i'll give you the phone number of head office

hope this helps

i haven't actually written anything up about my brakes. they are quite similar to what is described in the articles section. i still have more mods to do, but for now they work, and work great at that. i may get around to writing up something soon, although i've done nothing special from what is described in that article...
hmmmm, i can't decide whether to detail it here, or keep the post true to it's orig topic.... ahhh, what the hell, the TA22 isn't much diff in front susp to AE86...
my little additions to what's described int he article are mainly related to the discs... i had the discs sourced through a brake maunfacturer in melbourne and the discs were machined down to 266mm so that they fit the diameter of the pads correctly, while that was done, the discs were slotted and the mounting holes made to fit the corona hubs
i've since fitted the new master cylinder... from here all i paln is braided lines and 200SX pads, something like EBC green stuff... otherwise the standard hilux pads are like 80% and bite hard, so they'll do for now
next is suspension... new shocks (don't like monroe GT gas) and custom springs (current ones are cut just to get it on the road) things will keep happening, i'll post as i do them, but not at least for three weeks till uni exams are over...
