- Removing brake caliper piston without compressor – any tips / tricks?
If they’re still attached to the bike you can just pump them out with the brake lever.
However you’ll have to be very careful or you’ll only get one out of each caliper.
To get them both out you’ll have to hold back whichever one starts to move first and keep pulling the brake lever to get them both to pop simultaneously.Posted 4 years agoHicksyMember
Years ago, I needed to get a piston out of a 2CV caliper and a mates Dad came up with this mad cap idea for holding a bike pump adaptor hard against where the brake pipe went in and pumping away with bike pump. We sniggered at this right up until the point when the piston shot out and took the bulb in the garage with it!Posted 4 years agozeesaffaMember
Sorry if this seems like a stupid question.Hi all,
I need to replace the seals & pistons in a 2010 Elixir R caliper.
Any tips on how to get the pistons out without a compressor?
Is it possible to just squeeze them out as far as they’ll go with the lever before splitting the caliper and pulling them out with pliers?Posted 4 years ago
Or what happens if I keep pumping the lever? Won’t they eventually pop out anyway?
