Akebono brakes cannot be rebuilt?

street2soul

I was told by one of the Z guru shop mechanics that Akebonos on 370Z cannot be rebuilt. Supposedly, NISSAN says do NOT take two caliper halves apart, and they will not reseal properly. Nissan has a very specific guide to do this, but wasn't able to confirm anywhere. I was recommended to just buy the new calipers instead when the caliper life is "done" via too many track days, etc.

Anyone can chime in?

I agree to that, the deformation from heat will ultimately destroy its ability to be joined back together accurately. If for whatever reason they are structurally damaged from heat abuse, they'd be to deformed either way to put them back together, let alone take apart.

You probably already have a shop, but this is probably the most authorized race shop for nissan parts

If you are looking to just refresh the pistons/piston seals, you shouldn't have to take the caliper apart.

Thanks guys.

I call BS on taking the calipers apart. When they powder coat the calipers. They have to take them apart to replace the o-rings between the 2 halves. Rebuilding a 4 or 6 piston caliper isn't that hard to do. Been there, done that.

damn. knowing that you track the z, i feel like i should take mine apart now Lol

Rusty

I wouldn't take the calipers apart unless you see some leaking, or want to change the o-rings between the 2 halves. To freshen them up. Just replace the pistons, seals and duct covers.

BUT if you want to get adventurous.

This is what I do with putting the halves back together. I use HI-Spot bluing compound. This stuff shows the high spots between the 2 halve. Put a small amount on a piece of paper towel. Wipe it across one half. Putting a VERY thin coat down. Bolt the halves together. Torque to spec. Then unbolt it. Look at the half that didn't have the bluing compound on it. It should have the bluing on it. Good mating should show about 95% to 100% contact transfer of the bluing compound. Where there is no bluing, is a low spot. To fix that. Use a honing stone and lots of WD40 to stone the halves. You will have to repeat the process several times to get it right. The last couple of calipers I did. After checking the contact one time. Everything was good.

Try not to get the bluing compound on your skin. It's like walnut stain. It ain't coming off for awhile.

In the machine shop we used Dykem for practical jokes more than anything. perfect when someone lays their safety glasses down, add it to the nose bridge and temples. Also works great on handles of all kinds, coffee cups, especially if they are blue or black colored to begin with, backside of tools, ect.

I could tell you all kinds of stories!
Inside of work glove finger tips.
The underside of tools laying on a bench.
The backside of a broom standing in a corner.
The backside of a flashlight sitting on a urinal. My favorite. This was classic when it happened. It happened to a foreman to boot!
The flush handle of a toilet.
The backside of the microwave handle.
The ear piece on the phone on the foreman's platform.
The controls on a forklift, overhead crane.
Disconnect a air nozzle from an air line. Squeeze some inside of it. Reconnect the air line. Blow off your work piece. EVERYTHING is now blue.
Also putting mustard and ketchup packets under the toilet seat.
Rubbing limburger cheese on the sweatband on a welding helmet.

The best one that I do not recommend is the score a 20 oz plastic soda bottle with a razor blade. put lots of Dykem inside. Remove airhose from the wall.
Drill a hole that tightly! fits the long nozzle of the air gun and tape the handle down and seal it up around the nozzle. silently manuever the bottle near the person you hate and reconnect the airline. Not only is it extremely loud but bluing goes everywhere! Witnessed a firing over that prank.

Sorry Street, hijacked your thread.

Weld threaded pipe fitting to a vert steel beam in the shop. Screw a ball valve into the end of welded fitting. Screw pipe nipple and 90deg elbow into ball valve. Turn the elbow so that it's pointing up. Open ball valve and fill with water. Turn the elbow down. Do this to a couple of beams. Go tell the new guy that he has to go around a check the beams for moisture content. And he has to measure how much is in each beam. Then give the report to the general foreman, who is on the joke.

Some days I sure miss working in the shop jokes for days.
Newbie, go to the basement and get some more carbide inserts from storage. Stairs is in the president's office, in his closet is a trap door to the basement. He likes to control the inventory but dont worry anyone can just go in there.

Rusty

One foreman had a bicycle air pump painted bright yellow, with the words "SUNSHINE PUMP" on it. Sitting on a shelf in his office. Said it was for us asssholes who tried to blow sunshine up his asss when trying to explain our way out of trouble.
