Brake bleeder hand pump?

[Rok]

I have a brake bleeder hand pump and been using it for a year, but now it will not hold any pressure. i know it is not the fittings or the hose because I tested them on another pump. Is there any way to take the pump apart and fix it or do I just replace it? I assume there is some seals in the cylinder that just go bad? Thanks.

Most of the time it is the gauge that goes wonky, it is probably cheaper and easier to get a new one. Most pumps just aren't built that well.

If you know for certain the gauge is bad you can buy a new gauge from McMaster Carr, around $40 with shipping.
I can tell you how to fix the gauge but it requires a delicate touch in order to re-calibrate the spring mechanism, which is why it fails, it's not the seals.
Better to just buy a new one. All brake bleeders are made in China, there are no domestic manufacturers.
We sell both the plastic and metal units and they're on our website.
