In a brake antiskid system, when an approaching skid is sensed, the system takes the action of relieving the hydraulic pressure on the brake. This is to prevent the wheel from locking up and causing the vehicle to skid or lose control. Option A is incorrect because increasing the hydraulic pressure would likely worsen the skid. Option B is incorrect because shutting down the engine is not a common response in brake antiskid systems. Option D is incorrect because locking the wheel would not help prevent a skid, but rather contribute to it.
