∧∧∧Man, why'd you have to talk like that, bringing all kind of negativity into this thread. It seems like you're the one who's dumb for not understanding what spdrcr771 was trying to say. Nobody should waste their time talking to you. You better check people background first before saying he's dumb or whatever. What have you done for this forum if anybody may ask? I guess so, so shut up.

so since this question came up, there really isnt a way to get it done. My rear knuckles are at my machinist right now trying to figure out a way to make it work but because of the toe arms locations, drum hardware and the TPMS sensor there's really not a way to do it. if you got a small caliper from will wood you might be able to do it but as far as adding a stock caliper to the other side it cant be done.

Does your hydro setup lockup the drum or the caliper?

I'd assume the caliper, seeing as the e-brake it mechanically engaged.

Biggu, so there's absolutely no room to to put maybe, two IS300 rear calipers on (from what i can see from pictures online, they appear to be smaller), utilizing a custom bracket from the original mounting points, having them mounted right beside each other?

On a side note, I recently saw an Aston Martin Vantage and it has a dual rear caliper setup.

my hyrdo is inline and locks the caliper.

pieisgude,


It doesent look like it would be able to be done with a stock type caliper. it would probably have to be something to the effect of a small willwood caliper, nothing major is needed anyway

I know multi piston 2 piece calipers have the pistons per side separated and connected by an external hard line. That could in itself work by hooking up the hydro brake to one side, and the cars brakes to the other.

But, has anyone seen multi piston calipers that have pairs of pistons (like per side) separated. I remember seeing something goofy like it in an old option magazine. Can't remember if it was like what I first mentioned or what.

Late response but like a few people said:

In line hydro has multiple issues, among them changing the brake pedal feel, and bleeding issues. They don't always lock consistently either.

The drum brake would not have anything to do with a staging brake at all.

The drum brake is not good enough for locking the rear wheel (drifting)

I am just looking to see if anyone has ever seen someone fabricate a bracket for either a aftermarket wilwood or maybe a evo rear brembo or something.

Audi R8's have a dual caliper setup in the rear, the mini one serves as a parking brake. I'm not saying go buy an audi caliper, just illustrating what the OP wants-

Op, maybe something like this- http://www.wilwood.com/Calipers/Cali...temno=120-2281

With an aggressive pad maybe that will have enough bite to do what you need, and they're not crazy expensive.

Alright. I know this might sound entirely stupid. Biggu and Obeewon chime in on this. What if you ran a separate reservoir and MC that was smaller and used that on a separate hydro? I'm just talking out of my *** right now.

that would be the plan if you run dual calipers.

some one mentioned getting a dual piston caliper with a cross over tube. IMO that woudlnt work either because the pressure on the other side would cause the other side piston to recess back in and you would probably warp a rotor or so.

from what I have gathered from other people in japan, best bet is endless pads and new cables and adjust the crap outta it.

^^Yep Biggu hit it. The problem is the fluid running through the same line. As a matter of fact just the act of the caliper closing causes a weird pedal feel.

On a S14 the rear calipers can be used with the e-brake handle and you can feel the brake pedal dip when you do.

Im going to look into endless drum pads and a new cable. It just takes a lot of force to lock up.
