rebuilding z calipers trouble - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

ok so first a story.

I had my 26mm aluminum front calipers powdercoated. Than I rebuilt them with the rebuild kit from PDM. while I was rebuilding them I noticed a bunch of glass bead in the piston cups ( which would lead to that the brake oil lines were not taped or the tape failed during the cleaning process. ) no big deal right ? take the 4 bolts off each caliper, pop out the piston's, and wash them down with compressed air and a lot of brake cleaner. simple plan.

problem. 2 bolts ( the inner 2 of the 4 ) snapped inside on one caliper.
I went to nissan today to get replacement bolts ( I was prepared for dry insertion btw ) and they said that the caliper's are never supposed to be taken apart and now both caliper's are fucked.

any truth to this ? or is there a place or nissan dealership that can help me get the 2 bolts I need to put my caliper back into 1 peice ?

thanks for any help, if theyre fucked theyre fucked just say so.

No, who ever told you that is a fucking retard.

I just took mine apart and had them sprayed.

Talk to this guy about finding new bolts.

I just sent Mr. Russell a PM so hopefully he can source a couple bolts for me.

Nissan is correct in saying they're not supposed to be taken apart... for the most part

the bolts you can buy from anywhere

^ yea, but the manner in such the assclown's did so is more what got my gears grinding.

whats done is done though now it's finding the solution to the trouble

They're not supposed to be taken apart because they never made replacement o-rings for the fluid passages between the two halves. Z1motorsports has these o-rings for when you want to put the calipers back together.

I've been stressing (not really) about the caliper joint seals now that I've sent my halves to powder-coat. They were siliconed by the previous mechanic. I'm getting the whole rebuild setup from Z1 as suggested. Stress is all gone now.

Thanks for the tip - didn't know those guys since I Skyline. Glad I searched before asking!
