I need to bleed my brakes at some point and upon inspection I can see that the bleeding edge port cover is gone on one of my calipers.

Firstly, I’m going to have to try clean this port out throroughly before bleed as not to get any debris in the system.

Secondly, I cant find this for sale anywhere? Anyone using an alternative? Seems silly that such a small bit of rubber that can easily be lost does not have replacement listed!

I believe it can be found as part of a kit, but it suddenly becomes very expensive. The alternative seems to be piece of Gorilla tape and/or ear plug foam

Same issue here-I used a strip of gorilla tape.

Yeah did find it in a kit, but it was £24 I think!

Will get some Gotilla tape today and maybe clean it out with cleaner and cotton buds!
