From Rivets to Hooks: The Changing Brake Attachment Market
Relining and Rivets In the early days of BRAKE & FRONT END, the brake job was known as a reline. The technician would pull the drum and attach fresh friction material to the shoes at the shop. In 1931, a complete reline with adjustment could be had for $10.00! The shops could buy friction material

Nissan Tech Tip: Knocking Noise Above Idle
Engine "knock" may be heard on an applied vehicle just above engine idle speed (800-1,100 rpm) with the engine under a slight load. The noise cannot be detected over 1,100 rpm. The cause may be a normal pulsating noise coming from the EVAP purge solenoid valve and piping (in the engine compartment) transferring into the passenger cabin. However, use the following procedure to reduce the noise.
Tech Tip: Kia Cooling Fan Noise
Sedona engine cooling fan blades were redesigned as of August 23, 2001 production to reduce fan noise. The new-design engine cooling fan assembly may be used as a field fix for in-use complaint vehicles built before August 23, 2001 production.
Tech Tip: Volkswagen Coolant Pump Leakage
Coolant pump seals are designed to use coolant as a lubricant. This design intentionally uses a small amount of coolant to coat the seals during pump operation. Any excess coolant that accumulates will exit the weep hole when the engine cools down. Minute traces of coolant or lubricant residue around the weep hole is not evidence of a faulty pump. Do not confuse a leaking coolant pump with one that is functioning as designed.
Tech Tip: Diagnosing and Servicing a Coolant Leak
Water pumps work hard. As the miles add up, so does the wear and tear on the pump shaft bearing, seal and impeller. Erosion inside the pump can wear away the vanes on the impeller, causing it to pump less efficiently as the impeller is eaten away. This may lead to engine overheating on hot days or when the engine is working hard. If the water pump seal becomes worn, coolant will leak past the pump shaft or out of the small vent hole on the housing.
Tech Tip: Diagnosing Starting/Charging Systems
How many starters and alternators are replaced unnecessarily every year because of misdiagnosis? Nobody knows for sure, but suppliers of both new and remanufactured rotating electrical parts tell us more than half of their warranty returns have "no fault found" when the parts are examined. Many of these returns are from DIYers who lack diagnostic know-how, but some are from professional technicians who apparently lack the same skills.

Current Trends for Ignition Systems
As automotive technology moves forward, ignition systems are becoming more and more entangled with other systems on the engine. The current generation Nissan Maxima 3.5L V6, which was introduced in 2004, has a fairly conventional coil-on-plug (COP) ignition system. The individual coils are driven by the powertrain control module (PCM) using the input signal from
