Vehicle: 2004 Ford Focus ZTW 2.3 L4 GAS
While a detailed diagnostic procedure for all air conditioning systems would be impractical due to the many variations in construction and operation, there are three fundamental components of a total diagnosis:
- Refrigerant systems must have an adequate, but not excessive charge.
- Determination must be made whether the refrigerant system is governed by a cycling clutch compressor or by valves which control evaporator pressure.

BRAKE SERVICE PROCEDURES FOR 2004 Ford Focus AUTOMOBILES
Disc Brakes -> Front Disc Brakes -> Brake Disc Service
Vehicle: 2004 Ford Focus ZX5 2.3 L4 GAS
Disc brake service is critical because of the close tolerances required in machining the brake disc to ensure proper brake operation.
Maintaining close control of the shape of the rubbing surfaces is required to prevent brake roughness. In addition, the surface finish must be non-directional and maintained at a micro-inch finish. This is required to avoid pulls and erratic performance, and to promote long lining life and equal lining wear of both the lefthand and righthand brakes.
Do not attempt to refinish the rubbin...
