R33 Gt-R Rear Brake Torque Specs

[albertm7]

Hi everyone

I am planning to change out the rotor & pads but I don't know the bolt torque specs for the rear calipers

I know the front brakes are identical to the ones used in 350Z track edition, but I could not find the torque specs for the rear anywhere (to my knowledge, there is no full FSM for R33 GT-R, only the engine manual, in english at least)

Oh and this is my first post on this forum, I just got a R33 GT-R as my first car! they just became legal last year due to a 15 year old import law

Thanks in advance

Hey Albert,

Have you looked at the 300ZX online manual, probably would be the same.

it can be found here: http://www.300zx-twinturbo.com/cgi-bin/manual.cgi

If I read it correctly it says 98-118Nm for the front, couldn't figure out what it is for the back but they are the same size bolt on skylines, both bolting into alloy calipers so the torque should be about the same.

Somebody else might have a more definitive answer for you but I have never seen a brake service mechanic here in OZ use a torque wrench when refitting calipers.

Cheers

Hi Rob

Thanks for the quick reply

According to the 350z FSM, the front 2 bolts are 152.1 - 154.9 Nm and the flare nut is 14.8 - 17.6, I think I will go with these as they are the exact same brembos

I'll use the link you gave me as a last resort for the rear torque specs but it'd be reassuring to know the exact toque specs as the rotor size (300zx: 294.64 x 18, GT-R: 300 x 22) and the caliper brand & size (not sure about 300zx but GT-R: 40mm diameter, since the rotor is different size the calipers should be different too I think)

But in the end, as long as it's on there real tight, it shouldn't matter TOO much right?

152.1 - 154.9 Nm sound huge for the front which are M12 I think? The caliper is made of aluminum alloy so I think it should be less?

Ahh so confused now... I'm sure someone has done the brakes here before, does anyone have advice or torque specs that they used?
