Hello , most probably your valve block seals gone . If playing front side , then it's your front valve block .
If playing rear side , then it's your rear valve block . They have four pistons each and seals could be gone
so no proper pressure inside the block .

The problem is surely contamination of a valve block. A pair of 15-minute Rodeo Routines executed back-to-back has the potential to fix the problem. Otherwise valve block replacement or rebuild is indicated.

Majority of ABC problems are from the Valve blocks . Mine anyway .. I invested in a set of seals
and changed all seals on front and rear . SO far so good ..
