Caliper Slide Pin Rubber

[Roadrunner]

I've searched everywhere but came up empty. Can you buy just the rubber sleeve from the NB lower slide pin by itself?
Mine keeps swelling after a few track days making removal difficult. Starting to get a collection over the years of perfect condition pins with swollen rubbers in the shed. And it seems wasteful and isn't exactly cheap to replace the whole pin.

Alternatively, does anyone run the NB upper "rubber-less" pin in the lower position as well? I'm assuming the rubber is only to stop rattles, but if the top pin is rubberless and doesn't rattle then why would the bottom? Seems quite a few other brand cars run both slide pins without rubber sleeves.

I have some but I think they are part of a whole after market calliper overhaul kit. Don't look as good as OEM ones.

Run 2 sets of upper non rubber pins.
Been doing it for a while now with no issue.
I was doing as you are just spending money on pins all the time.
The down side is supposed to be more pad knockback but I did not notice any difference when I made the jump a few years ago.


Btw.
Nc uses the same pins.
I had the brass ring at the end of the pin break off and jam on the previous NC.
Must have been gradual as I only picked it up when I found 1 pad badly worn.
Was an absolute arse to remove the pin and then the brass ring.
Another reason to just run 2 plain pins.

Thanks for the confirmation Luke! I’ll pick up some solid pins and run rubberless

So to close this out, I've been running a soild upper slide pin in the lower spot for about 5 months now. No rattle noises, no pad knock back or anything. I changed brake pads a couple weeks ago, pin slid out without any effort. So easy.
I'll never use the rubber pins again.

I don't think Mazda Australia sells just the rubber sleeve.

I don't think it's track time swells the rubber.

My brand new pins were tight from the get go.
Fronts seemed ok, rears seemed unreasonably tight.

Like you, I've run mine (rears) without the sleeve and half a sleeve and not noticed any noise increase.

I can't say the same for the EBC Green rear pad clips. I need to find the old pad clips and re-install those..


I read somewhere that these slider pins are engineered this way to make sure the leading edge of the pad contacts first, and also to minimise rattle, obviously.

I just don't see why the rears need to be so tight.
