Caliper Science Friction
Disc brake calipers come in many sizes and configurations, including fixed-caliper, multi-piston designs, and the more modern floating-caliper, single piston designs that may also contain a mechanically actuated parking brake. Needless to say, disc brake calipers have undergone a series of design changes that continue to make them more adaptable to late-model vehicle applications. To
Universal Coolants: The Ultimate Answer?
For nearly a decade, vehicle manufacturers have been introducing and using a variety of extended-life coolants. The only thing these coolants have in common is that they all seem to differ in formulation and color. There are orange coolants, green coolants, blue coolants, red coolants, yellow coolants, even pink ones. The proliferation of different coolant

Temperature Control Essentials: Pinpointing the Causes of Cooling System Failures
Managing heat is definitely a hot job these days. The cooling systems in most late-model import passenger cars have been downsized to reduce weight and bulk. At the same time, most new cars and trucks are now factory equipped with air conditioning, which puts an added strain on the cooling system’s ability to manage heat.
Loaded Brake Calipers: Can They Boost Productivity?
Some technicians like loaded calipers because everything they need comes in one box. They don’t have to worry about mismatched parts from different suppliers and the complete assemblies are quick and easy to install. Most importantly, they see fewer comebacks because of brake noise or other problems. Loaded calipers do provide a variety of benefits
ABS Bleeding Service Pointers Help Complete the Job Right the First Time
Honda Honda has a well-deserved reputation for overall vehicle reliability, which extends to the ABS system. For the most part, bleeding the system will present no unusual problems. Caution: A word of warning when working around the accumulator and modulator assembly. The brake fluid is under thousands of pounds of pressure (3,625-5,075 psi). Be sure
Replacing FWD Wheel Bearings
When a wheel bearing goes out on a FWD car or minivan, it may or may not give much warning. Typical clues include noise from the vicinity of the wheel, possibly some steering wander or looseness in the steering, and/or some abnormal tread wear on the front tires. Also, an ABS light could illuminate. Any
Servicing Mazda Electrical Systems: Starting and Charging Diagnostics
While it sounds obvious, the battery is often overlooked when dealing with an electrical problem. Actually, the battery should be more of a maintenance item than a repair issue. I have to think by now all successful import specialist shops are relying on maintenance work to keep their bays profitable. Checking and servicing the battery
Brake Hardware: Lessons Learned From a Little Piece of Wire
Every technician has struggled with those little wire clips that push the pads onto the pistons on first-generation Mazda Miatas. Those little clips that barely fit into the painted-over holes on the new pads and can shoot across the shop like a rubber band can make a big difference. One racecar builder who specializes building
Brake Dynamometer Testing: One Test is Worth a Thousand Expert Opinions
Some friction material companies market their products by saying they are third-party tested or tested on their own brake dynamometer. But, understanding what this really means is tough if you do not understand how a brake dynamometer operates. In the engine performance world, an engine dynamometer is associated with measuring performance. Brake dynamometers also measure
Servicing Cartridge FWD Wheel Bearings
Early front-wheel-drive wheel bearing service was difficult and time intensive. The most common arrangement was a pair of tapered roller bearings similar to that of a rear-wheel-drive vehicle, but with a spacer between the bearings. Servicing this arrangement took time and often special tools. Of course, an axle shaft went through the bearings and spacer.
Battery Tech: How to Inspect, Charge and Replace
The first test of a battery is a visual inspection. There are certain things a technician should look for when inspecting a battery. Some things to look for include the quality of the connection from the battery to the cables. Cracks or other leaks can cause acid spills. Missing battery hold down hardware can cause
