So I have two left over small rubber tubes after doing the front brakes. They are about 1 inch long and 1/8 inch hole.  Its not the caliper pin sleeves, but I am thinking it might be part of the lower pin. That pin has an indention and thought maybe it fell off when taking them in out. 

 

 Any ideas? I just found it laying on the floor after I finished, never saw it come off.

 

Thanks!

 

 

bleeder covers?

The lower slide pin has a captive rubber sleeve, but it's only ~1/4" long.

Could be indeed the lower slide-pin sleeve. Here there is an exploded view:

I assume it is part a4 (under label 12) 

I have removed these on both sides because it caused my slide pin to be jammed and took me 2 hours with a hammer to carefully get it out.

rverdoold, that is it. Thanks. That is what I was assuming it to be, but when I put it on it didn't freely push back in. 

 

So you havent been using it without issue?

 

Thanks,

Yes until now (40 k miles) It did not gave any problems. Probably when I will replace my brake pads and discs next time I will order a refurbish kit and try them again but that will be at least an other 60k away. Until then I drive it like it is now.

 

What I do at every interval (7.5k) is taking the brake pads off the car, and check if they can move freely, additionally I clean and regrease the slide pins too (slidepin grease from european brake vendor) and apply copper paste on the brake pads and guide plates.
