I am in the middle of fitting my D2 6 pots to the front of my 33 GTR. I have the drivers side on, no problem. Passenger side, i have put the disk on, held it on with wheel nuts then fitted the caliper. The disk is extremely close to the inside brake pad. When i spin the disk it spins freely until a certain point then gets stiff.

I can still push it through by hand with a little bit of force then it loosens up again.

Is it going to be OK like this? If i drive it will it just wear the pad enough to stop it from rubbing?

I really don't know what else to do. The washers that come with it to space it are no good as they just push the pad even closer to the rotor.

Any ideas?

Put it all together, bleed thoroughly, and drive back and forth (not on the road and with no hard braking) and then jack it up and see if it is still binding. I would not be keen to try to get rid of the problem by hard braking, You want it all lining up properly before you bed the pads and discs in as per instructions.

Does the piston go all the way back in? Tried levering it in (without the pad and opening the bleed screw)?

Yeah the pistons are all the way in, the whole kit is brand new.

I also had a look at the passenger side and that is pretty similar.

I have just been trying to get it straight for the last 4 hours with no luck. I have tried swapping the brackets. I have tried fitting the brackets in every way possible, you can only bolt the calipers with them one way which is the original way i put them on.

They only need to move over a tiny bit. I really don't know what else to do now.

hmm not awesome. they will still work fine but the inner pad will wear faster than it should. I think you already said the shims would worsen the problem not correct it.

Assuming all mounting surfaces are flat and straight eg no small metal dags pushing it out, your only option to correct it would be to have the adapters machined to take a mm or 3 off. Or you can just pretend it never happened and live with faster pad wear than you should have. Or return them....

OK thanks for that mate. I dont drive the car much so wear is not a huge issue, it probably does about 1000 miles a year. Although i would like it to be fitted correctly really! Yeah, the shims will just push the caliper even closer to the pad.

I am sure all mounting surfaces are flat, I will check again tomorrow though.

I am in talks with the company i bought them from who are talking to the factory that make them so will see what they say. I cant really send them back though, i have sold my brembos :(

I'm with Duncan on this one.

Once you've double checked all mounting faces are free of scale/debris, check the clearance again.

Either have the supplier send some better spec (slightly thinner) adaptor brackets, or get yours machined. Take off 0.5mm will probably resolve everything. Not a big or expensive job.

I have managed to get the brakes on properly. There was a metal nipple that was touching the mounting bracket a tiny bit which was stopping it from sitting flat against the hub. It was quite hard to see that it was touching as it was so minmal but it kept catching my eye and I had a feeling it was because of that.


I ground it down and refit the mounts, disk and calipers and they all line up perfectly!

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
