DIY: Sport Brake Caliper Rebuild

Sounds like some elbow grease will get the bolt out...

Mine: Akebono Sport Brakes (4 Piston)

Yes there is a difference. My Nissan caliper kit came with 1 Pink and 4 orange packets of grease. I assume the Pink is the rubber grease for the seals and boots. What the heck is the Orange grease for?

Instructions say: "When the slide pin is placed in the cylinder (I think they mean caliper) apply some Orange colored grease on a surface of the slide pin itself".

What they mean? Boot retaining ring?

Update: Nope, that ain't what they mean. Buttheads gave instructions for 2 piston brakes which do have a "sliding pin" bolt. Confusing as hell.

Here's another treat from Nissan: They did not include the small round seal that seals the 2 caliper halves together (where the Hyd. fluid passes from one side to the other). Yes I split my calipers to make it easier to service. Nissan does not sell this small seal. Does anyone know where these can be purchased?

Thanks for any info

I learned this the hard way on a Sunday afternoon. Went to separate the calipers and they twisted, shearing this little o-ring in half. And you're right, they're not included in the rebuild kit.

So....

Go to Napa or Autozone and buy a complete O-ring kit with various sizes. I luckily found an open store that evening and one of the sizes worked perfectly. Just match them up and you're good to go. Never had any problems with it.

Anyone know what the four 17mm bolts are called for the rear caliper. I snapped mine off

17mm? On the sport brake rear caliper?

I'm not aware of any 17 mm bolts. I know there are two 19 mm mounting bolts and then four 14 mm bolts on each rear caliper.

Yes I’m sorry the four 14mm

If you have at least one bolt still intact, maybe you can try to source an identical replacement locally (I'd try Fastenal).

They are 17mm on the front calipers

My buddy had to extra bolts laying around. Going to fastnel tomorrow to pick 16 of them. This diy suggested 80ft lbs is ABSOLUTELY WRONG. On the four bolts. High tighten and 1/4 turn after the caliper is on the car.
