Just a heads up, I suggest anyone with an S1 should check their rear calipers for freedom of movement and the condition of the larger (top as fitted) sliding pin.

My partner broke one in her Dayz on Friday, and when we went to replace it and the pads (as the caliper had seized on an angle), the other one turned out to be broken also.

Both were old fractures as shown by darkened/discoloured metal and corrosion. For whatever reason the passenger side piston housing rotated up off the pads and the piston pushed almost all the way out with the result being a near total lack of brakes.

The only symptoms leading up to finding this were occasional brake squeak when moving at low speed, and a long pedal stroke in general. Both rear caliper slides had completely seized, and its my opinion the action of the piston is what broke the pins finally.

The drivers side pin was so seized as to need to be punched out in a hydraulic press.

The pins are available through Nissan ex-Melbourne and are approx $35 each, I would suggest purchasing a pair and replacing them.

Just did that recently. Its good advice for any car - the grease on the pins wont last forever, and the remainder that I wiped off the old pins was dark brown/black. I just re-coated the pins and holes with dow corning 111.

I hope you didnt put the new pins in dry. I would even be hesitant to use new pins without knowing whether the old pins caused damage inside the holes.

New pins went in with goss drylube. Reamed the holes lightly to clean them up. The thing is when they seize, it will pivot at the neck of the pin until it fatigues and breaks, so I think its well worth checking, two on the same car suggest its not an isolated issue...Wreckers I tried for calipers were useless as theirs were seized also.

      Thanks for the linkie. Certainly always a great deal of help when people post comparisons like these, but I think for now I'll stay away from any semi slicks. I did go ahead and order the sportcontact 7. My buddy has them on his modified A4 and he keeps saying how good they are. For my intended purposes these will probably work real well. I'll report on them once I had the chance to try them out

      Talk about noisy. Even when I still had the Tomei under the car I could distinctly hear the tires rolling. And I doubt I ever will need maximum grip like on a track. My GTR will maybe never even see the 600hp mark and I need to get used to the car quite a bit before challenging the limits of its handling. For the next winter storage I think I will get a set of these rubber drive-on thingies that have a tire shaped base. Those supposedly really help prevent flat spots.

      Well our climate is definitely way less hot overall and the weather can be quite picky at times. I just know that during normal road use or even spirited drives there is no way I'd be able to consistently stay in the operating temperature, and constantly changing the tire pressure would also be a royal pain.

      Input shaft bearing. They all do it. There is always rollover noise in Nissan boxes - particularly the big box. Don't worry about it unless it gets really growly.

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
