ASD Motorsports Rear Wilwood Kit

[HaloRiot]

Sorry guys if this has been found before or discussed but i couldn't find it in the search.

I was looking for rear brake kits that utilize a Wilwood 4 piston caliper and came across this. It also incorporates an E-brake.

Has anyone heard of this kit or opinions?

So for $900 you replace the Z32 caliper and drum ebrake with a Wilwood caliper and integrated hydraulic ebrake? I guess you save the weight of the drum hardware, but I don't see a huge benefit here. The pad selection and cost savings is a wash at this cost. I'd say just keep the Z32 rear setup if you want something bigger with an ebrake. If I were to spend money on the back, I'd want it to be lighter and use a 4 piston FSL so you could run the same pads as in front with Def's kit. I'd also want it to ditch the ebrake, but I don't drift or DD my car.

...yeah it actually looks more like a "turning brake" since the stock Z32 e-brake hardware stays intact... so you'd have no rear brake except as provided by the mastercylinder attached to the big dumb handle...with another (stock) handle for the "parking brake"

Or something otherwise i couldn't imagine needing a new mastercylinder

the only alternative i could see is if this is an aditional closed loop system that adds a 2nd caliper to the rear so you have the 4 wheel brake system, the hydraulic "turning brake" and the standard Z32 e-brake...FML this seems like a clusterfluff

More light on the subject:

Short Answer: This is a bolt on kit for the driftoriffic kiddies to get a hydraulic E Brake.

The silly thing is it is not even FD legal (FD requires separate calipers for hydraulic e brakes).

You have to cut off your stock brake tabs and bolt the adapter between the hub and upright just to get the Willwood caliper to mount.

Description
ASD S13 4 Piston Pass Through E-Brake Kit - $899

Exclusively through ASD!

We developed this kit with the budget conscious S13 owner in mind. Most of us don't want to shell out the big bucks for the dual rear caliper setup that requires you to run larger aftermarket rotors, changes the front to rear bias of the brake system, etc. For those of you that run our 4 piston or 6 piston front brake upgrades, or the Z32 front caliper upgrade, this is what you have been looking for!

This is a completely bolt on kit that only takes a couple hours to install. We have a thorough installation document that comes with it, as well as can be downloaded from the left menu section.

Included in the kit is:

S13 pull-up e-brake handle w/master cylinder
(2) Wilwood 4 piston calipers
(2) ASD Caliper Mount Brackets
(2) Brembo OEM Z32 rotors
Wilwood BP20 pads
Complete stainless steel brake line kit
Complete hardware kit for bolt in installation


IMHO it's pretty pointless when the OEM cable E-Brake works perfectly fine with the right pads, and now you don't have a real e-brake for street parking use. Especially when OEM brakes are perfectly adequate for drifting and large, vented rotors with 4 piston calipers are just extra weight and expense.

If you are going to spend $900 for a hydro ebrake might as well do it right and install a FD legal dual calipers setup.

For non drift use just install the Z32 set up if you want budget upgrade or consider other options that don't have $250 worth of hydro ebrake parts and a large, expensive CNC adapter in the kit price.

wow I couldn't have imagined it was THAT useless...amazing

[Matt93SE]

What a worthless piece of dorifto sheit... ZERO rear brakes by the brake pedal since you cut off the regular tabs, and you can't double-up on the hydraulics to feed one caliper......

[Def]

I'm pretty sure you still have rear brakes under normal braking. The manually activated master cylinder just gives you another way to put pressure on the rear brakes.

They went with the crappiest Wilwood caliper though... The pads are almost half stock thickness.

[Matt93SE]

How do they keep hydraulic pressure from backing up into the master cylinder and shoving fluid upstream? Maybe dual check valves, but I'd be scared to see what happens to a check valve that gets slammed with 1000psi a dozen times a lap.

[Def]

Yea, I think they use check valves on it. Probably not the safest thing... but then again, a cheap check valve keeps the booster working on all cars out there just fine...

[Matt93SE]

But those aren't subjected to brake line pressures like this would be. (nor were they designed to, as these should be.)

Is there a safe way to have a hydraulic hand brake with just the one caliper per wheel. I'm thinking about getting rid of all of the Z32 parking brake stuff to loose the weight. I would really like to have some kind of "e brake" to make it easier to load the car on a trailer and stuff of that nature. I was thinking about taking a page out of the drifter's book with one of their "hydro e-brake kits". Thoughts?

[Z28ricer]

Not sure about a hyd ebrake, but i'm looking into doing a single piston PBR caliper in the rear, they're used on 89-97 camaro/firebird, they have a built in ebrake setup, hopefully it on an 11.75x.81" 2 piece rotor will provide adequate braking, as well as a very lightweight setup.

[No Rotr]

I'm not looking to reinvent the wheel here. The Z32 caliper works just fine, and my brakes are balanced very nicely as they are so I don't wanna change calipers and mess with that. I just want to loose all the factory e-brake stuff and put in a hyd. brake for simplicity and less weight. I see pass through master cylinders used in motorsports all the time so there has to be a correct way to do it.

[Z28ricer]

If you want to do a hyd handbrake and have it be done properly you have to do a new additional caliper, how you take care of the mounting is up to you, heres one example.

Also not sure whats up with the "reinvent the wheel" thing, the majority of the good upgrades and common stuff around here would seem like it would fit right into your statement, as most is working to make a better replacement for the run of the mill setups that are available, really cant see a simple bracket to use a caliper from a different vehicle as such.

[No Rotr]

By reinvent the wheel I meant changing out the rotor and calipers. I'm just fine with the Z32 calipers and I already have the pads I need for them. They are plenty big and bolt right on. The rotors could be a little better, but again they work just fine for me. I know the new drift rules require a second caliper for a hyd. e-brake, but I know there is a correct way to do it and just use one caliper.

No, there is not.
