Wilwood 240sx dual caliper Hydraulic hidden e-brake setup – (10% combo discount)

Avoid wasting time shopping around for all the individual parts, getting custom brake lines made up, or running generic parts that may or may not work.

The GKTECH S-chassis dual calliper hidden hydraulic e-brake setup is the only COMPLETE kit available anywhere. Literally, everything required is included and it’s a range of GKTECH and Wilwood components. If you have an S-chassis and you want your rear brakes to lock up in an instant, this kit is the way to go.

Now available with our hidden hydrcaulic e-brake assembly for that stealth OEM look and feel in your cabin.

The contents: 

Hidden handbrake assembly: 
Self explanatory, this is the handbrake assembly that houses master cylinder and converts your OEM cable setup into a lever to engage the master cylinder. 

Master cylinder:
Choose between 5/8″ and 3/4″. For the Wilwood 2 pot calipers our recommendation is 5/8″ but more on that below in the FAQ’s. 

Dual caliper brackets:
The bracket that allows the Wilwood caliper to fit on your OEM knuckle. Note: can only be used with OEM steel knuckles. Will not work with GT-R, R34 or Z32 aluminum knuckles. 

If you are running the Gktech knuckles then you wouldn’t need the bracket as the knuckles accommodate for the Wilwood calipers already.

Braided lines:
Made in-house in Australia using stainless steel fittings and using stainless steel braided line with a PTFE outer these lines are made specifically to suit Nissan S chassis and even include the P clips to locate the line throughout your vehicle.

The GKTECH braided brake lines are assembled using stainless steel fittings and hose that consists of a Teflon inner tube wrapped in stainless steel braid and a PVC outer coating for protection.

Brake calipers:
We have opted for the Wilwood 120-10188 caliper for this setup. They are a small but bitey caliper and only caliper that we found to work with the OEM 9mm thick rotors. 

Brake pads:
Over the years we have tested many brake pads with these calipers and ended up at the Wilwood BP-10’s. They’re economical, readily available, very bitey and last. 

Axle spacers:
As our dual caliper bracket spaces the hub out 7mm this results in the driveshaft essentially being stretched that 7mm to compensate for the thickness of the plate. This can now be taken up with the use of an axle spacer.

We have different sized options available as it is also a good opportunity to select a different size axle spacer if you were running a different diff/driveshafts combination or have a very low vehicle.

NOTE: If you are running standard hubs/knuckles the 5mm axle spacer is required

NOTE#2: Will NOT fit European delivered S-chassis’ without the use of JDM or USDM calipers/rotors.

NOTE#3: Designed to be used with standard S-chassis 9mm rear rotors

NOTE#4: The wilwood calipers have a mounting hole of 3/8inch (9.52mm) and the studs used on our brackets are 10mm and as such the 2 mounting holes needs to be drilled out on the calipers to 10mm. This is very much a DIY kit and is easy to do.

NOTE#5: The brackets themselves will NOT fit the Gktech rear drop knuckle

NOTE#6: For the axle spacers, we can only confirm fitment on OEM wheel bearings
