cause i have a s13 as my weekday DD and a weekend warrior

advice could be helpful

In the first picture he has a Hydro, and the stock E brake. In the following pictures he has it in the stock location and im assuming its not a daily driven car.
The hydro SHOULD NOT be used as a parking brake, because the pressure decreases over time. For an event on flat surface i dont see it being a problem, but if you are daily driving and parking thats a big NO NO. (At least i wouldnt chance it)

anyone know if you can make a ASD hydro a reverse pull? or how to do that?? its kinda hard to put it in a good spot in my 14 where i have it now i dont really get good enough leverage i feel

[Nixon]

does the proportioning valve work? if it does how do you install it?

i just installed the PSM inline setup and am having a really hard time bleeding it. it hardly slows the car down. (stock s13 calipers w autozone pads) i ordered EBC yellows to help

PM'ed with a kit I make for stuff I think might fix your issue.

Was wondering what people thought about $220 kits with lines done? Seems somewhat like a reasonable price no?

The cylinder has to be compressed either way...so if you change the pivot point of the handle (so the pivot is above the MC) you would reverse the way the handle would have to move to compress the cylinder. Hope that made sense.

One of my sponsors came out with a new way of mounting the e-brake.









Thought I'd post it here.

[EvoVIII808]

Any info on the mount. I would like for mine to be in that location but sit lower down on the tunnel.

Damnit... was working on something similar but of course home made. Thought I would be able to share the idea lol. Damn

Looks good though.

Explained the same thing to him basically.

so does anyone have any experience with the proportioning valve?

Yes, great use for racing. Never really noticed too much use in drifting.

Will the s13 mount work for s14? I didn't think there was much if any difference in the tranny tunnel

It should fit. All you may have to do is maybe re-drill the holes with the slightly bigger bit just for some le-way of space. Normally S13 metal tranny rings fit on S14's as well so shouldnt have much of an issue. If you do though, just try the redrill as the changes will be very small.

ok so i have the parts shop max in-line setup. i have stock s13 calipers w autozone pads. i was finally able to bleed it using a Mityvac vaccum bleeder. my brake pedal feels firm again, no sponginess or anything, and the psm handbrake barely slows the car down. my stock e-brake locks up the tires just fine. any ideas?

i think swapping in better pads will help but if my stock e-brake locks them up right now i dont see the use of the in-line setup. i think ill start saving up for the dual caliper setup :-(

Okay.. somewhat confused.
You have two hand brakes? Hydro and the stock wired handbrake?

If so, the stock handbrake will lock if you pull hard enough unless you have already stretched the cable. Hydro handbrake will of course lock the rear brakes because its just like slamming on your brakes but on the rear only.

Replace your stock cable and make sure its on tight but not tight enough to engage the brakes.

Hope this helps.

Unless the pads are completely worn down, it wont be the pads.

Goodluck.

[Nixon]

ok so

-PSM hydro in-line only slows the car down even though its been thoroughly bled.

-stock cable e-brake locks them up fine

so i dont think its an issue with the brake pads

[tauntdevil]

Something tells me you are bleeding it incorrectly. Have had many friends have the same issue and that was the cause. Try putting a hose into a small water bottle down to near the bottom of the bottle. Mostly use a vacuum line. Fill the bottle with brake fluid about a quarter of the way up. Just make sure its above the end of the hose and connect the other side of the hose to the brake bleeder. Then you can leave it open and bleed without having to worry about air getting sucked back in.

Also, make sure to start from the caliper thats furthest away from the master cylinder which in an S14 (not sure if S13 is the same but I dont doubt it) it would be the drivers rear caliper.

[EvoVIII808]

is you handle long enough to provide the proper leverage to lock the brakes? mine wasnt and had to be extended

[StatticMyke]

di-devol - that is killer. link didn't work for me. wonder if this would work with a rhd car or would it have to be rotated.

[di-devol]

For RHD, you would just flip it over.


Looks like they updated their links.

I'm so glad you posted this link!

I have the ASD vertical-pull style one, and the base is so narrow I was struggling how to mount it on the trans tunnel. I can sleep better now lol

i had the same problem.
-i had the PBM inline, i welded the brake in place with the cylinder off to make sure the seals didn't mess up then installed the lines. bled the lines over 5 times. confirmed with PBM i had ran the lines properly. the hand lever was super firm but would not lock up the rears what so ever. only when it was raining it would slightly lock up the rears,
-i tried to completely remove the cable handbrake to ensure there was nothing interfering, no dice. . i switched out for another set of used s13 rear capipers with auto zone pads. . no dice . .i did talk to PBM they said they would work with me if by the time i order 300zx rear calipers and it does the same thing they will try and figure something out with me . . .I was thinking its an isolated incident but your story sounds exactly like mine

We would first like to thank Our sponsored driver for dropping our name in this thread... All of our hydros are custom made to order to the customers specs... We make everything except the Wilwood cylinder and internal yoke by hand to order... We also make custom mounting plates for many vehicles including S13, S14, RX-7 FC, Lexus SC, and the AE86... Please feel free to contact us at 503.419.7803 or www.levelrideconcepts.com

I am a bit curious on exactly what lines one would need for a dual caliper setup, because you can't use the factory hard line anymore. I am assuming just buy another rear hard line and mount it with the factory line. Thanks for any answer.

You can use hard lines if you want, it would just have to be the same as the factory setup where its a hard line to the back and into a Tee fitting, then goes out to both sides, at the ends, they change over to a flexible line and connect to the calipers. Thought its just easier to pay the extra amount to get flexible lines at the start, you can do it either way.

It would require a completely different set of lines from the hydro to each caliper...the stock lines would remain untouched.

One line off hydro. Tee one line into two, one going to each caliper. Done

I understand that you can't use the factory line, hence why I suggested buying another hard line and basically run them both right next to each other. I will probably end up going with flexible lines though.

Thanks for the answers.

How does a proportioning valve affect a in-line Hydraulic Handbrake setup?

I know a proportioning valve controls/limits the amount of fluid that can pass through. Therefore allowing you to change braking bias front to rear.

I notice that some people use them, while many do not. What are the pros and cons?

You have to run the z32 rear calipers for the pbm unit to work properly. I had the same issue with my car with the s13 calipers. It would not lock up for shit. Switched to z32 rears and it locks up my 265's with no problem.

Anybody knows if the pbm hydro will work with the dyna pro wilwood calipers before I purchase the hydro?
