quick intrest check on hydraulic e brake kit

[ricers1]

i have had some ideas floating around and i did a decent amount of research. i have not come across any hydraulic e brake kit. Well the only ones i found replaced the ebrake handle and tied onto the oem brake lines and rear caliper using a t-fitting. those kits are not a good idea... first, if u have abs, it wont work properly. (i know the abs system will see that the wheel has stopped and will go wacky, but you wont be using the brakes so it wont make a diference. if you had the system tied into the oem stuff, my thinking is that it would affect the the pressure in the caliper and not work as it should.) second, if u tie into the oem lines and a line goes, you have no way of stopping... my idea is to make a deticated system, that will be cost effective. i.e. making a bracket that can use the oem ebrake handle, this way, if you want, you can keep all your oem trim and not have to modify anything to make it all fit. my goal is to make it all pretty much a bolt in system, run the lines and bleed the system. and you can use a second oem caliper in the rear. or use a upgraded 2 or 4 pot caliper.

its not like this kit hasnt been made, it has been made by pro teams and i havent seen anyone selling it for cars. obviously it would say off-road use only because some states require u to have your oem equipped e brake. i dont even have an idea on cost because of machining will be expensive.

i just want to see who would want a kit for their car so im not wasting my time. i will try to make the entire kit about 2-500. but that all depends on machining and material cost.

i will use my s13 to start with. if some one knows what a s13 oem caliper will fit(besides an s13) post it up. ill start with the s13, my friend has an old rx7, so that would be another kit to make. and as i go along and people donate thier car for a few days or whatever it takes to make a new kit, i can come out with more. but all that depends on the response i get from here.

no comments?? nothin

It's hard to make a kit for something like that dude. By the time most people are upgrading to the point they are thinking about hydro e-brakes, they already have a bunch of custom parts and they have the ability to either fab it themselves or know someone who can.

Do it though, someone will buy it. I'd love to have it, but I'm nowhere near that point yet.

[Dattebayo]

Um, your regular brakes are hydraulic. Just get a line lock and rig it up to a button or something.

But the whole point of a e-brake is that is is used in emergencies. Like when your hydraulics fail?

[ryandevilhorns]

For drifting I'm assuming, that would be pointless on a steet 240. Stock rear calipers have cable and hydraulic.

Who the fu*k are you talking to?

[IanS]

There is really no logic in your thinking.

What would be the purpose of using hydrolics as opposed to cables? The factory systems generally work well, and are relatively maintenance free.

First of all, adding a second calliper to the rear doesn't make sense. Not only will it be difficult to package, but it will also add lots of extra weight, which is bad. And that is unsprung weight, which is worse. Yes, in motorsports it is occasionally done, but that is with ultralight alloy callipers on fully custom knuckles.

Secondly. the whole purpose of a hydrolic side brake (called such because its not there for parking or emergencies as much) is for motorsports. Hydrolic systems are easier to tweak, and stronger, plus you can switch out brake systems, without figuring out what cables work.

The ABS issue? 99% of people who have a need for a hydrolic side brake, had long since dispatched with the the ABS and stability control.

Also, how do you plan to use a factory lever to activate the hydrolic system? Factory levers are meant to pull on a cable, while hydrolic system pushes on a master cylinder. I think you will have a much harder time packaging all that under factory interior, which is often rather tight.

Not to mention the upkeep and maintenance on the system would be much worse than on a cable setup.

It really just does not make sense. If you need a hydrolic side brake, then you likely want to move it anyway. The reason they put racing sidebrakes upright, or in custom locations, is because it is often very difficult to reach a side brake while strapped into a rigid bucket seat.

Y-O-U.

Then why are you answering a question I didn't ask?

well the oem cables stretch over time, an oem caliper is really not all that heavy. and you would be taking out the parking shoes, and all the working of that system. i only said my goal is too try to get everything under the factory trim, also i would be selling the caliper with the kit, so if one chooses they can get alloy 2 pot caliper or whatever.

really the only maintainance would be replacing pads from time to time but they would be used as much as regular brakes so they would wear as fast. and ive had experiance with the parking shoes falling apart and getting jammed in the brake rotor and causing more issues

[Dattebayo]

Yeah, they stretch out over a period of YEARS. Hydraulics require more maintenance than that.

You have no idea what you're talking about.

and you would be taking out the parking shoes, and all the working of that system.

240sx's don't have parking shoes. You're confusing the Z32 brake swap with it.

i only said my goal is too try to get everything under the factory trim, also i would be selling the caliper with the kit, so if one chooses they can get alloy 2 pot caliper or whatever.

"Alloy 2 pot"? You really come off like a silly salesman who only knows about 10% about his product.

Okay, so you actually think someone would install a whole other caliper on the rear in addition to the one that's already there? This is the silliest idea in history.
No to mention the engineering is all off. There is a specific reason that the stock calipers are in the position they are with respect to the rotor...

I own two cars with Hydro E-brakes...

neither of which came as a kit. You have to make them work for you application.

I dont know if this helps, but I didnt want Dave having ALL of the fun

So what did you do then, rich? Or are you not at liberty to discuss it?

[Koshin]

I didnt touch this one man. My buddy Dave Mitchko (the guy who does the work that I cant do to the race cars) figured this one out. I wouldve just messed something up. I know it works though haha

I would go thru the trouble of getting the info for him, but I dont care enough to know how it works to do so.

Im a jerk

...PS, (so are you Dave)

I know.

I would be willing to bet you don't have a whole other caliper, tho.

[Koshin]

nope, I do know that

I dont see it being needed. Im no engineer, but seems excessive

[Dattebayo]

Like I said, it's an adaption on a line locker, probably...

Both rears are the same line (on most cars), so I don't see why it would be so hard if you really wanted it so badly. It sure wouldn't sell as a kit, tho.

[Koshin]

most people dont need a Hydro e-brake....its really kind of a waste of money unless youre tracking the car pretty regularly. Unless some ricer just wants to be a JayDee Em Toite Dorifto mobile like I have a feeling the OP is....

just sayin

[93coupe]

I keep my hydro on lock. That ish is expensive.

I wish you would let me hydrate your locks.

Golden shower, oooh that's dirty

[Speedy7_7]

Hey guys, I was interested in finding out if people wanted to buy a dual climate kit for their 240. I was thinking I would just run a second motor to heat the passenger side of the car, and run ac to it as well. you would get to keep the stock trim in your garage if you wanted, and you will need to update your rear shocks and springs to handle the generator and refrigeration unit.
