2006 M35. Brake caliper slide pin locked up

[Korben15]

Hi all. Ok, I was going to change the brakes and one of the 2 push-pins, if that's what they're called, on the front right brake caliper locked up. I had to knock the living crap out of it to get it to release. Needless to say, it popped out of the piece that was holding it in and it's temporarily being held in place with a load of grease. When I brake at higher speeds now, it feels like I have a highly warped rotor, which I take it is due to the pressure difference on the top vs bottom half of the brake pad. Once I Fully engage the brakes the 'skipping' sensation stops. What all goes into replacing one of these? Can I order just the pin and replace that, or does the whole caliper need to be replaced? Any links to the part?

Thanks,
David

They're called slide pins, and will corrode if the boot is compromised. I assume that's the thing you mentioned popping out?

And I agree the pulsing is due to the wobbly nature of the caliper now. Depending on how badly corroded the pin is, you could salvage it by dremel, sanding etc. They're usually cheap enough that I just buy a new kit if I'm in doubt.

And since most times these are attached to the bracket rather than the caliper, even a bad case of corrosion shouldn't involve caliper replacement.

I haven't had to replace them on my M yet, but looking at the hardware in my garage, the process shouldn't be that different from when I did it for another car.

I'm just posting my own video since I've done it, but look up those key words and other instructions should show up.

Also, since I haven't done it on this car, I'm not sure of the part numbers involved, but I bet auto parts stores will have these parts aplenty for most Nissans. Hopefully someone who has actually done it will chime in.
