Answer 1

The brake of a car laid up on a yard track would 'creep off' most quickly due to a slow leak in the brake pipe.

Step-by-step explanation:

In this situation, the brake of a car laid up on a yard track would 'creep off' most quickly due to a slow leak in the brake pipe.

The brake pipe is an important component of the air brake system in a train or car and it supplies air pressure to the brakes.

When the air compressor is cut out of service, the brake pipe gradually loses pressure, causing the brakes to release or 'creep off'.

For example, if there is a slow leak in the brake pipe, the air pressure will decrease at a faster rate, causing the brakes to release even more quickly.
