Keep Your Lexus Shipshape.
Imagine how a giant such as Toyota, among the largest automakers in the world and known for its advanced technology, could ever recall its cars.
Unfortunately, inanimate objects and mass produced products do encounter glitches. In an automobile the braking system is a sub-assembly and the essential components in the modern disc braking system are the master cylinder, brake pads, piston containing caliper and rotor mounted on the hub. By making use of the various parts the automobile is brought to a halt when the driver depresses the brake pedal. The automobile uses a hydraulic system to link the brake pedal with the brake system on the wheel.
The reliability of the brake system is dependent on proper maintenance of all the different parts of the brake system and the watch word is repeatability. The braking system performs a number of operations when the brake pedal is depressed and the entire system must perform the same kind of operation without fail every time. That is the essence of repeatability.
To ensure 100% repeatability, maintenance of the braking system is absolutely essential and the following five important aspects must be taken care of:
1. Brake fluid must be topped up and master cylinder constantly checked.
2. Damaged brake pads must be replaced.
3. Tyres must be road worthy.
4. Wheel alignment must be perfect.
5. Air pressure on tyres must be adequate.
While some of the maintenance functions can be undertaken by the driver, others need to be handled by professionals. The Lexus automobile is a high performance machine and requires experts to perform maintenance functions. Lexus repair can and should be undertaken only by technicians trained by Toyota.

That Toyota does not train its technicians properly.
That Toyota's brake system is faulty.
That Toyota is one of the largest manufacturers of cars in the world and is also known for its advanced technology.
The passage talks about a 'sub-assembly.' From the passage what can you infer about the term?
It means that it is a sub-standard part of the car.
It means that the braking system is a part of the overall car and the braking system itself is an assembly of parts particular to the system.
It means it is an assembly of sub-standard parts.
It means that anything that is to be recalled is called a sub-assembly.
