Braking with Tradition: Siemens VDO Plans Series Production of By-Wire Brake this Decade
Siemens VDO has developed a vehicle braking concept consisting of about 30 percent hardware and 70 percent electronics – a 180 degree change from traditional hydraulic braking systems.
Selecting the Right Friction Material
How do you select the right brake pad for a vehicle? And, how do you select the right friction line to stock at your shop or have as your first call? These are difficult questions to answer. Every time your shop installs a set of brake pads on a vehicle you are taking a gamble
Twin-Piston Calipers: Are Two Pistons Better than One?
generate more torque. More torque means more stopping power. Also, by using the floating caliper design instead of an opposing piston design, engineers are able to avoid wheel clearance issues and other robust design features of the floating caliper. With a single-piston caliper, the footprint of pad is limited in some ways to the diameter
Collision-Related Alignments: It’s All in the Angles
src=”elements/100656.gif” width=”180″ height=”131″ alt=”” border=”0″ align=”baseline” /> When a vehicle is involved in an accident, extreme forces are placed upon the design characteristics of the structure, as well as all related and attached system components. This energy management of the collision forces is what began the need for technical training and the formation of I-CAR.

Buying an Import Scan Tool
Thinking about buying a new scan tool? Choosing a tool that provides the best coverage and the most diagnostic bang for your buck isn’t easy with so many different products to choose from today. There are simple code reader tools, entry-level “generic” scan tools, professional-grade tools with bi-directional communication and additional test capabilities, OEM scan
Diagnostic Solutions: Oxygen Sensor Diagnostics
Once considered leading-edge technology, today’s oxygen sensor has become a commonplace service item on modern vehicles. Popularly introduced in the 1970s, the Lambda or, as it’s more popularly known, the oxygen sensor, rapidly became standard equipment as it’s a vital component of closed-loop or feedback fuel control technology. By using a voltage input from the
Wheel Balancing: Making a Smart Investment in a Wheel Balancer
When you consider that only 1/4-ounce of wheel imbalance can produce a noticeable vibration on a vehicle, it’s easy to understand why it’s so important to have a wheel balancer that is both accurate and easy to use. Many balancers in today’s marketplace are capable of balancing a wheel to within a few hundredths of
Battery Charging: All Charged Up!
A battery charger is something every shop should own, and most do. But battery technology has changed in recent years. Battery chargers that were designed for older conventional lead acid batteries (called “flooded” cell batteries because the cells are filled with liquid electrolyte) may not be the best choice for newer batteries with absorbent glass
Tech Tip: Top-Notch Design is Key When Selecting New Filters
Veteran auto mechanics will remember the days of oil-bath air filters, cartridge-type oil filters and sediment-bowl fuel filters. While these early-design filters would work well under a narrow range of circumstances, most were woefully inefficient and inadequate in the long term. All were subject to careless installation and dirt contamination during servicing.
