DESCRIPTION
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 use the only kit on the market that allows a working handbrake for when you want to park your car. This kit literally includes everything required other than the calipers. If you are running Skyline or Z32 2 pot rear calipers/rotors and you want your rear brakes to lock up in an instant, this kit is the way to go.
This kit has everything you need to set up a dual caliper hydro handbrake in your car, just BYO calipers.
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 2 pot calipers our recommendation is 5/8" but more on that below in the FAQ's.
Braided lines:
Made in-house in Australia using quality HEL stainless steel fittings and using stainless steel braided line with a PTFE outer these lines are made specifically to suit Nissan S/R chassis and even include the P clips to locate the line throughout your vehicle.
Dual caliper brackets:
The GKTECH dual caliper bracket is unique in that it doesn't require the use of Mustang rotors (common among others) and only spaces the hub out 7mm's with limited modifications required to fit. This kit is by far the best kit on the market and also allows the use of the drum brake. If you are running aftermarket knuckles that already have the provision for dual caliper brackets (like our knuckles) then you don't need this bracket and it can be de-selected.
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.
Vehicle Compatibility:
- Nissan 180sx
- Nissan S13 Silvia
- Nissan S14 200SX
- Nissan S15 200SX
- Nissan Skyline R32 GTS, GTS-T & GTR (non Brembo)
- Nissan Skyline R32 GTS4
- Nissan Skyline R33 GTS, GTS-T
- Nissan Skyline R33 GTS4
- Nissan Skyline R34 25GT
- Nissan Skyline R34 25GT-T
- Nissan C33
- Nissan C34
- Nissan C35
- Nissan A31 Cefiro
- Nissan 300ZX Z32
NOTE: If you are running standard hubs/knuckles the 5mm axle spacer is recommended
NOTE#2: Will NOT fit Z32/GTR/R34 aluminium rear knuckles without some trimming of the knuckle (not too difficult)
NOTE#3: For the axle spacers, we can only confirm fitment on OEM wheel bearings
FAQ'S
What's the difference between non hidden and your hidden handbrake setup?Our hidden handbrake assembly uses the OEM lever and the assembly itself can be hidden under the center console. The advantage of using the OEM lever is that you'll still have a locking handbrake for parking and your interior will look untouched. 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 7mm, which is also why we have axle spacers included.
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 cut your standard brake caliper mounts off, trim your brake dust cover to suit and shave the calipers where they butt up against one another, that's all you need to do to fit this bracket.
Can I still use my drum handbrake?Yes and no. Our dual caliper brackets do allow the use of a drum handbrake however by using the OEM lever with our hidden handbrake assembly you are disconnecting the OEM lever to the rear cable. If you specifically want to keeep the OEM drum you will need to use our non hidden handbrake assembly.
Is there anything else needed for installation?Yes, everything is included in the kit with the only exception of the brake calipers (maybe $100 or so a pair from a wreckers?) and brake fluid. We include EVERYTHING else! BYO tools.
Will this kit work with aftermarket knuckles?The brackets are designed to be used with the OEM knuckles. They can NOT be used with aftermarket knuckles. If your aftermarket knuckles happen to have dual caliper brackets already (like ours) then you can remove the brackets from this kit by deselecting them in the dropdown menu.
Will these work with OEM S-Chassis calipers?No they will not. These brackets will only work with Nissan 2pot calipers and their corresponding rotor Will these work with OEM non turbo Skyline or Z32 calipers?No they will not. These brackets will only work with Nissan 2pot calipers and their corresponding rotorHow do I know what size axle spacer to choose?This kit comes with a bracket that is needed to mount the dual caliper bracket, this bracket goes between the hub and the knuckle.By installing this bracket you are spacing the hub out 7mm, this is taken up by the driveshaft.This causing the bearings inside the driveshaft to run on the edge of the cup, which can lead to premature failures.We suggest adding axle spacers to put the stretched amount back into the driveshaft to ensure it runs further inside the cup and in turn is stronger and more reliable.We recommend checking which size you need by jacking your car up and dropping it down on ramps, this will load the suspension to its normal operating height. From there, disconnect the diff to driveshaft bolts and with the driveshaft in a relaxed position measure the gap.Keep in mind the distance of the plate that is supplied with this kit and factor that into the final number, that will tell you what size axle spacer you need.How do I know which size master cylinder to choose?Typically the 5/8 master cylinder is proven on an S/R/Z chassis running the single or two pot brakes, the lever feel with this master is balanced, having a longer more typical throw to gauge feel while still efficiently locking the rear brakes. The 3/4 master cylinder is larger, so when used in that same setup the lever feel will be more direct, firmer, and require less throw to lock the rear brakes. However, if you are running larger brakes/wheel tyre setup then the standard two pot and 235 width tyre and do require a bit more bite, we would suggest this master cylinder.
