A bad break

Something was wrong with his brakes. Rock had just backed his car out of an apartment complex parking space, but when he stepped on the brake pedal, it offered no resistance and depressed to the floorboard. As his car rolled backward, downhill toward a row of parked cars, Rocked pumped the pedal as rapidly as he could. He began to feel pressure build and his car had begun to slow, but it seemed there was no way it could possibly stop before it struck one of the parked cars. Nevertheless, he continued to pump the brake until his car stopped inches from the trunk of a black sedan.
