G Series & F Series Diff Disc Brake Solutions

[LittleRedSpirit]

Well its 4 stud for starters, so Id perfer a kit for my f series that uses an unmodified vented rotor, but not too great a diameter, maybe as big as a stock ae86 front rotor. Then its kind of in proportion with the upgraded fronts people tend to use that fit inside their 15s.

Also, if the outer surface of the caliper sticks out past the axle face with the rotor on top then they would mean most peoples wheels wouldn't fit, like some rx7 front caliper setups can.

Im definitely in the market for something, and there isnt much around for the mx13 diff.

I was just considering buying a wilwood rear caliper with a handbrake function and trying to find a floating vented rotor that fits over the axle plate and has the right stud pattern already, then adapt it.

What handbrake system does the nissan caliper use?

How similar hydraulically is the caliper? What master cylinder bore does it require to feel right?

Do you have pictures?

Matt,
Skyline and Z32 are drum handbrake, twin piston caliper on the rear, if they're turbo. NA r33 is 4 stud and I think has a single piston not sure about the handbrake mechanism on them. They are mostly BM44 which is 15/16" master.

Silvia is BM38 which is 7/8". Silvia has single piston rear with built in handbrake.

SW20 is vented rotor and has inbuilt handbrake. It's an option if you want vented rear with builtin handbrake.

Oh, and I doubt you'll find a caliper with a hat big enough to fit over the drum mounting surfacing. Me and my mate both got our axle faces trimmed down to fit inside disc. I never seen an MX13 diff so maybe they have a much smaller disc mounting surface. Mate was smart and made his concentric with ID of disc hat so it located on that.
