Sram Hydro Brake performance

Heya,
Ive got sram apex on my Ti bike, which is great in every way…. Save for the brakes which are just a little lack lustre. Especially the back seems to have very little power.

I’ve had them bled and re-filled with dot. The only thing that helps is brand new pads, but after a few weeks they are back to feeling like rim brakes.

I’ve had 105 and ultegra hydro on my other bikes and never had this issue?

Wondering if I’m alone is this or if there is known sram issue? Have searched but couldn’t find anyone with similar issues :frowning:
