Possibly air in the lines, find someone knowledgable to help you bleed them
One reason could be that air is trapped try bleeding them.
Spongy or soft brake pedal usually means there is air trapped in the system. Bleed the brakes starting at the RR then LR > RF and ending at the LF.
Air trapped in the brake lines. Bleed your brakes and that will solve the problem.
The brakes need to be replaced when they feel soft or show signs of enough wear during visual inspection to warrant replacement, the same as any car.
If your brakes feel like they are pulling you should get them checked out. These brakes may need to be replaced.
Soft brakes are caused by moisture or air in the brake lines. This reduces the pressure in side the system and greatly reduces its stopping power.
The wall of the cyst would determine how hard it would feel, some with thick walls feel hard, with thin walls they feel soft
yes you can of you were asking "can you feel anti lock brakes pulsating" not sure why
I would check brakes,shocks,and powersteering pump. I would check brakes,shocks,and powersteering pump.
Probably air in the system.
a soft pedal could be the result of worn down linings, like the rear brakes needing adjustment, leaking hydraulic cylinders....
probably have a bad master cylinder.
