Z32 caliper bridge bolt size - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hi everyone. Yesterday I noticed that one of my bridge bolts that holds the 2 halves of the caliper together had backed out and is now gone and lost for the ages. The other 3 have been re tightened and seems to be keeping everything in good order. I need to find a replacement for the 4th bolt. However Nissan doesn't list this with a part number because the caliper isn't supposed to be split. My question for everyone is, what are the specs for this bolt? Anyone know the length, diameter, thread pitch, etc? I don't want to take off another bridge bolt for fear further damaging the caliper. Has anyone with crap caliper laying around can take some measurements for me?

I can get you some measurements later today if no one else chimes in...

If you could, that would be great!

Blah, I see what you mean with how they don't list it. If the other guy doesn't get a measurement to you, i might be able to later.

You're thinking of the bolt that secures the caliper to the hub. The bridge bolt is not represented on that page.

m10 x 1.25 pitch

length of the bolt including head is 106.75mm

length of shank and thread 96.5

threads are 31.5mm

So any 14mm m10x1.25x100 should work (100 being 100mm in length). Bear in mind you will probably have to get a separate washer so that will reduce the length by a few mm. I've found it hard at times to find those flange bolts in certain sizing.

Look around and see, I'm sure you can easily find a replacement that will work.

Thank you a million time over! That information is perfect. I should be able to find something to make it work. Thanks again.
