Whilst changing a wheel my rear hydraulic brake has gone 'soft' It becomes stiff again if i pump it but quickly goes soft again.

what do i do to fix it?

Brake is a tektro auriga comp

Sounds like you've got air in your brake system and need to bleed it?

 

[weely]

so how do i do that?

Don't you have a maintenance manual with your bike?

Different makes of brakes will have different methods of bleeding them - sorry I'm not familiar with your model.

I've just googled "how to bleed Tektro Auriga Comp" and other Forum's seem to recommend a bleeding kit to bleed these brakes.
