I've had this condition for years, now let's see your opinion...
So, in drive the problem comes basically only on slippery surface; when you release the brake pedal, wheels are still locked for a while and you can't control the ride like you should.. My car has passed inspections several times with this cond, brake forces themselves are good.
front - calipers, pads, brake hoses
rear - calipers, rotors, rearmost lines, rearmost hoses.
Preliminary tests reveal that if I grap the pedal with my hand and pull it back, so do the brakes.
Between the lines from main cylinder to rear and rearmost lines there are hoses. Could those be plugged and cause this problem? Something with brake booster / vacuum things? Thanks already.
