Tech Tip: Pointers for Inspecting Brake Systems
Brake linings are sacrificial components designed to convert kinetic energy into heat energy by rubbing against a rotating brake rotor or drum. This rubbing action or friction wears away a miniscule portion of the brake lining and rotor or drum each time the brake pedal is applied.
Tech Tip: Brake Fluid Q & A
What are the fundamental differences between synthetic fluid and conventional DOT 3 and 4? Simple, it all comes down to the base stock. Both synthetic and conventional brake fluids start from the same "polyethylene glycol" stock. But, to make synthetic brake fluid the manufacturer will "synthesize" the original base stock and make the molecules better and more consistent.
Tech Tip: Let Nitrogen Make You Money
If you’re shopping for a nitrogen generator, here are a few things to consider. Does the unit you’re buying feature an "auto down" that results in less wear and tear on the compressor, not to mention less energy use? Also look for such features as a complete pre-filtration package that offers reliability and long operating life. Does the generator have a receiver tank included? Consider if you would fare better with a floor- or wall-mounted unit.
S-K Hand Tool Offers Universal Spline Sockets
Unlike the traditional spline socket, S-K Hand Tool’s Universal Spline Sockets feature a design that works on various fasteners such as spline, 6-point, 12-point, female Torx, square and even 50% rounded. Each Universal Spline Socket is like having six different sockets in one.
Tech Tip: Performing Profitable Radiator Service
Unlike their soldered-brass predecessors, today’s aluminum-core, plastic-tank radiators are not only environmentally friendly, they are lightweight, easy to service, less costly to produce and very efficient at keeping modern, high-output engines operating at optimum temperature. Because of their affordability and because they can be inspected while removed for a timing belt replacement or other front-mounted engine accessory service, aluminum radiators also make a good add-on sale during any major engine service.
Brake Fluid Q & A
Mike Evangelo of Dynamic Motorsports and Rossion Automotive e-mailed me with six questions about brake fluid. I like a challenge, so here are my answers. 1. What are the fundamental differences between synthetic fluid and conventional DOT 3 and 4? Simple, it all comes down to the base stock. Both synthetic and conventional brake fluids
Wheel Speed Sensors Replacement: WSS, Chevy, GM
By Larry Carley, Technical Editor When engineers came up with the idea of putting the wheel speed sensor (WSS) and tone ring inside a sealed wheel bearing hub assembly, it seemed like a great idea. The sealed environment would help protect the sensor and make it less vulnerable to damage or contamination from the outside
Diagnostic Dilemmas: Got a Light?
Every diagnostic technician experiences operational complaints that are more bizarre than they are technically complex. The problem is made difficult when the technician fails to stand back from the problem and look at what I call, “The Big Picture.” As you will see in the following case study, The Big Picture is a collection of
Brake Tools: Brake Service Tools & Equipment
Brake work is one of the cornerstones of the automotive repair business, so it’s important to make sure you have the right tools and equipment to service the brakes on today’s vehicles. Most shops that do brake work have some type of brake fluid flushing and bleeding equipment (a power bleeder, vacuum bleeder or injector
Dodge Tech Tip: Rear Brake Cyclic Rubbing Sound
A cyclic swoosh, squawk, squeak or grunt sound from the rear of the vehicle may be heard during medium to light brake application on vehicles equipped with rear drum brakes. The sound will be related to the speed at which the tire/wheel turns (one sound per revolution of the tire/wheel). If the vehicle operator describes the subject Symptom/Condition, test drive the vehicle to verify.
