EvilRufusKay Posted March 4, 2006 Share Posted March 4, 2006 I took my old solid rotors to my lathe and cut off the top of the hats. Then milled abot 5 thou of each side = free kinda heavy, but it worked out well! FYI JSK is no longer doing Datsun stuff... or so I am told.

bjhines Posted March 6, 2006 Share Posted March 6, 2006 I obtained a set of spacers used.... with calipers and rotors on a wrecked car.. I figured I would just swap them onto my running track 240Z... Well..... wasn't that a lot tougher than it had to be.... I ordered caliper seal kits.. sandblasted and painted the cailper bodies...cleaned and reassembled them....good as new.. nice pistons too. I sent 2 sets of 1984 300ZX rotors to the local shop to have them turned... I figured this would be a half day event..swap em bleed em and burn em... Well... first off.. part numbers???? I ordered caliper seals for a 1988 toyota four runner.... WRONG!!! that caliper has big and small pistons, staggered.... My calipers had 4 large pistons of the same size... I own a 1995 Toyota Land Cruiser.. and i recognized these pistons.... Sure enough The seal kit for a Land cruiser has the correct seals...but the Land Cruiser's calipers used banjo bolts instead of the flare fittings on mine...Hmmmmm... there is another version of this caliper..but I didn't figure it out... at least the seals and boots were the same... secondly....fitment?????? I got one set of rotors back turned in good condition.. the others were so heat checked they did not turn them... I carefully cleaned and reassembled the spacers and the hubs... and I bolted the freshly cut and cleaned rotors on with 35ft/lbs torque... I mounted the brake system on the car and checked fitment and runout... bent ears?????? The drivers side caliper interfered with the rotor...evidently one of the mounting ears on my strut was bent in a previous life...There is VERY little clearance for the disk in this set up.. I eventually got it right... bent rotors????? Both freshly turned rotors had significant runout... 0.25mm left side and 0.6mm on the right side... ouch!!! spec is <0.20mm... It turns out that the way to do this is to mount the rotors on the hubs and take the assembly to the machine shop and have them turned on the hubs. I found this out the hard way by ordering NEW rotors from NAPA... they were even worse.. I bitched and moaned and returned them... I ordered a new set from "Mountain Brakes"... they are Japanese rotors.. and they were better but still out of round more than spec..... I had the new Mountain rotors turned on the hubs and got it right.... I tried clocking the rotors 90* and 180*.. I clocked the spacers too.. The warp was always the rotors... not the hubs and spacers... I did find a set of bad hubs(race turned in hub body)... and those hubs also had a few loose lugs... I chucked those in the trash... I ended up with new bearings and seals installed with new cotterpins and grease caps on a good set of 240Z hubs... Ohh... on a final note... You can get a male to male flare adaptor from Pegasus racing that will allow you to simply plug the stock brake lines into the back of the calipers... very neat... Some folks may need an AN#4 adaptor to male flare... you will have to look at your lines if you are running stainless/teflon... Quote Link to comment Share on other sites More sharing options...

Drax240z Posted March 12, 2006 Share Posted March 12, 2006 I have a 5 bolt spacer set for sale with 5 bolt hubs, and rotors if interested... shoot me a PM if that is what you are doing. Quote Link to comment Share on other sites More sharing options...
auxilary Posted March 13, 2006 Share Posted March 13, 2006 whatever you do, DO NOT LOOK IN THE THREAD CALLED 'HELP! WHAT BRAKES OPTIONS ARE AVAILABLE...' that's stickied at the top of the forum. That thread will definitely NOT have the information you're looking for. Sorry, your question is a lost cause Quote Link to comment Share on other sites More sharing options...
