The GKTECH S-chassis dual caliper bracket allows the use of a Wilwood 120-10188 caliper in conjunction with an OEM S chassis rotor/caliper combo for use as a standalone hydraulic handbrake. It is super simple to install with the only modification being to the standard dust cover.

Alternatively, 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 and check out our complete kits:

Vehicle Compatibility: - Nissan S13 240sx - Nissan S14 240sx - Nissan S15 Silvia - Nissan A31 Cefiro

NOTE: designed to be used with USDM or JDM S-chassis 9mm rear rotors and will NOT work with Skyline/Z32 rotors and will NOT fit with European S-chassis' calipers/rotors NOTE #2: 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 need to be drilled out on the calipers to 10mm. This is very much a DIY kit and is easy to do. NOTE#3: The brackets themselves will NOT fit the Gktech rear drop knuckle

FAQS

I've heard dual caliper brackets push your hub out?
Yes, some can as much as 12mm, however, our brackets only push the hub out 6mm. 

What modifications are required?
Fitting an extra caliper in this space is not easy but this bracket does make things a lot easier and is an easy install. Simply trim your brake dust cover to suit. No other modifications are required. 

Can I use a Wilwood caliper with a Skyline/Z32 rear rotor?
No. Wilwood doesn't make a caliper with the correct thickness to suit a Skyline or Z32 rear rotor and as such, we don't have something to suit. This setup will ONLY work with S-chassis 9mm rear rotors in conjunction with an OEM rear caliper. 

Do you sell the calipers to suit this bracket?
We only sell these calipers in our complete kit and do not sell them on their own. The complete kit can be seen here: https://us./products/combo-packages/wilwood-s-chassis-dual-caliper-hydraulic-e-brake-setup-10-combo-discount
