As I recall, the only thing that pressurizes the front brakes is squeezing the hand brake lever, so you must have a restriction in the hydraulic lines somewhere. You’re pressurizing it when you  squeeze the lever, and the restriction is preventing the pressure from being fully released, so every time you squeeze the lever, you add a little more pressure to the system. That points to a pinched hydraulic line, a bad master cylinder, or an obstruction in the line, probably where it splits.There’s only a single line coming out of the master cylinder, but it has brakes on both front wheels, so there has to be a junction block somewhere in there  to split the line. Are both front brakes locking up, or just one? If it’s one, you know the problem is between the junction block and that caliper. If it’s both, it has to be in the junction block, the hose from the master cylinder to the junction block, or the master cylinder.</blockquote>
