300zx brake problems - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So today I decided to go ahead and install my 300zx brakes and 5 lug swap onto my s13. We got everything together, but once I got to the point where I was mounting the caliper onto the rotor and spindle, the fit was VERY snug. Like I sort of had to beat it down with my palm thinking it will be snug temporarily. The hub itself wouldnt move at all, but like I said, I was thinking it was going to be temporary bc everything is new. I'm pretty sure that I have 30 mm alum calipers and that I'm using a 30 mm rotor. Once everything was bolted up and the brakes were bled, I tried to go out and bed the brakes, but there was ridiculous amount of grinding, brakes were locked in the same closed position so I stopped and reversed back into my spot to be safe. I figured I'll just remove the rotors tomorrow and have them machined down a bit unless I totally have incompatible parts.

Here's the stuff that I'm using

these are the calipers I bought; on importnuts page it says that 26 mm only came on the 90 NA, but these are claimed to be from a 90 TT so theyre supposedly 30 mm
FS: TT 300zx z32 front calipers - $100 - VAdriven.com Forums

I'm using Axxis Ultimate brake pads I bought from thmotorsports on here, with brake quiet applied behind em.

and these are the rotors I'm using

Beck Arnley 080-2386 which I know fits 30 mm calipers bc theyre used from 91 up.
1991-1996 Nissan 300ZX - Beck Arnley Front Brake Disc

It's dark outside so I'm going to measure the actual width tomorrow and compare to importnuts measurements.

What do you guys think? I actually have 26 mm? rotors are wrong? just keep pushing the car til it fits right? Thx in advance.

edit I also installed a 17/16 BMC

measure the caliper using this The Definitive 300ZX Brake Swap!

but def sounds like you got 26mm Calipers using 30mm rotors

druthafoo · 04-17-2009, 11:18 PM

the calipers were compressed fully when I slid them on with the pads. From what I've read/heard theyre supposed to just slip on and be fit but not snug. Is that right?

You should not have to beat the caliper, everything should just fit fine. Even with brand new pads and rotors there shouldn't be an epic struggle to get them on. Check to see if you have 26mm calipers.

I think you might have got some 26mm 300zx N/A caliper. You will need some N/A rotors or some rotors off a Q45. Other than that you can redeck the rotors by taking off at least 2mm

Yep.. I measured them earlier this morning and got a measurement of exactly 1 and 3/16 which is a 26mm caliper. F me. Well I'm getting new rotors tomorrow morning.

Do you guys think my brake pads are effed? or should they still be fine?
