Failing Master Cylinder: Classic Symptoms
Anyone who works on brakes should be familiar with basic hydraulics and the various components that make up the hydraulic portion of the brake system. So if you’re not as familiar with this subject as you should be, keep reading and we’ll refresh your memory. We’ll start at the heart of the system, which is
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
Directions: Caution — Dangerous Precedent Ahead
A case had been shaping up in New York last month that could have set a dangerous precedent for the vehicle repair industry. In a scary move, prosecutors in Wampsville, NY, last year filed homicide charges against a muffler shop manager who inspected a car just days before it hit and killed an 8-year-old girl.
Diagnostic Dilemmas: Navigating OBD II Scan Tool Diagnostics
Although some hybrid OBD I/OBD II versions existed as early as 1994, the current version of OBD II was introduced in 1996. Because OBD II is a scan tool-based diagnostic system, diagnostic techs have become much more reliant upon the scan tool as a primary method of diagnosing malfunction indicator light (MIL) issues. In addition
Odds & Ends: Book Report
The classic Sebring race of 1970 – when Mario Andretti’s Ferrari 512 passed the Peter Revson/Steve McQueen Porsche 908 in the closing minutes to win by a scant 23 seconds – is relived in a new hardbound book, 12 Hours of Sebring 1970. The book has more than 100 photos and includes comments from Andretti,
This is a Great Time for the Brake Industry
As the editor of BRAKE & FRONT END, I make it a point to try out as many friction materials as possible. I have tried $20 pads, and expensive performance pads that can cost as much as $180 a set. I fint it amazing what a great set of brake pads or shoes can do
Seasonal Service
It’s that time of year again. Time to start promoting seasonal service checks. So before family hits the road for vacation with gas possibly hitting $3 per gallon, here are some service items that should be checked. TIRES Tires obviously play a very important role in safe driving because of their affect on traction, handling
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
Cracking the Code: Understanding Friction Material Edge Codes
Just about every brake pad or shoe you install has a cryptic code printed on the side of the friction material. As a technician, being able to read this code is just as important as the Dewey Decimal system is to a librarian. The “Edge Code” can tell you information about the product you are
Yes, It is Rocket Science!
W hen I was a young man, I remember my dad saying something to the effect that working on cars wasn’t exactly rocket science. He was right. In the days of carburetors and contact point ignition systems, a mechanic didn’t need much diagnostic equipment. All you needed was a timing light to check spark timing,
