Q I own a ’93 Chevrolet Suburban 1500. I had to replace the rear brakes at 17,000 miles, though the front brakes were still at 30 percent. My dealer couldn’t give me a reasonable explanation as to why the rear brakes wore out before the front brakes. They tried to pawn it off that I either rode with the emergency brake on or I did a lot of towing. Do you have an explanation for this phenomenon?Lester BrillS. Setauket, N.Y. A Usually the front brakes wear out first, leaving about 30 percent on the rears. Your vehicle has a brake component called the brake-pressure metering valve, which directs more pressure to the front brakes, and this may be malfunctioning. Your Suburban has ABS, so have your technician check the rear-wheel anti-lock control module and anti-lock pressure differential valve. Either of these two parts could be responsible for the unnecessary rear brake wear. Q My friend only drives her car approximately 2000 miles a year. She drives the car every day from … [Read more...] about The Motorized World

Editor’s Note: As the anticipation builds for the first drive of the 2011 Ford Mustang GT on March 29, we’ve decided to go into the archives this week to highlight the history of the Mustang 5.0 from past issues of Motor Trend. Enjoy! Is the new Chrysler entry into the American-produced GT arena a viable alternative to the traditional Camaro/Mustang/Firebird/Capri regulars? Not an easy question to answer, given the circumstances surrounding our confrontation with it. Normally we would just gather one up, test it until it cried for mercy, and then, armed with a stack of test data, arrive at an answer. But in the case of the Dodge Daytona (the original 0-24 code was a pre-production engineering designation) and/or Chrysler Laser, we couldn’t exactly do that because the cars don’t go on sale until this fall, and Chrysler balked at letting us do a full test on the only pre-production unit the company had at the time. We heard the word “irreplaceable” … [Read more...] about Comparison: 1983 Ford Mustang GT vs 1983 Chevrolet Camaro Z28 vs 1984 Dodge Daytona Turbo Z
When it comes to building hot rods there’s always a few gremlins that sneak into the mix along the way. One frustrating malady is a malfunctioning or inadequate charging system. Having to jump-start your hot rod nearly every time you shut it down is about as aggravating a problem as you can experience. With this in mind, we’re going to take a look at alternators as the foundation of a charging system and, while we’re at it, also introduce you to one new and exciting product from Powermaster Motorsports that has been designed specifically for traditional-style hot rods-the new PowerGEN alternator. Retro Meets Techno The success of the initial PowerGEN was overwhelming. The traditional hot rod crowd (a huge and continuously growing segment of the hobby) had been waiting semi-patiently for someone to successfully develop the perfect finishing touch in their quest for true retro engine styling-and Powermaster heeded their call. In the short time since the PowerGEN’s … [Read more...] about Malfunctioning Charging System – All Charged Up
Ah, the dual-clutch transmission. There was once a time where upon hearing that a car was to be equipped with one, motorheads would speculate on whether it would deliver incredibly quick shift times made famous by Volkswagen’s DSG, enhancing a car’s ‘fun to drive’ factor. Things have certainly changed since then – now when a car buyer hears that a car is equipped with an advanced dual-clutch transmission, they ask whether it is a wet clutch or dry clutch system and what the failure rate of the ‘box is. Although we’ve heard of issues with both types of dual-clutch transmissions, it’s the general belief that dry clutch versions of the transmission are far more problematic. Wet clutches run in an oil bath, and are generally used for higher torque applications, where there is more energy and heat to handle and the oil helps cool the gearbox down. However, as a downside, wet clutch gearboxes have higher parasitic losses because the oil has to … [Read more...] about Dual-clutch transmissions: dry clutch on the way out?
Shirley Shahan is the first woman to win an NHRA event in a pro class. While that’s a drag racing milestone and represents a legendary accomplishment, especially in 1965 when drag racing was completely dominated by men, if that’s all you know about her life then you only know the easy part. Known as the “Drag-On-Lady” with then-husband HL Shahan, who tuned her cars, she was also working full time raising three children, as well as participating in another sport she loved; fast pitch softball. Softball developed her upper body, which helped slamming a 4-speed in the quarter-mile. Racing every weekend in the 1950s with her kids in tow, she won the first Bakersfield March Meet in 1959 with her 4-speed 1958 Chevy in a Super Stock field of 40 men. By the mid-1960s she was racing for Plymouth full-time. A woman winning races in those pre-women’s lib days did not always go over well with the competition, and she was winning a lot of races. Switching to AMC … [Read more...] about The First Woman to Win an NHRA Event In a Pro Class Is Only Part of Her Story
Max Warburton and his team. Warburton, of Bernstein Research, assembled a team to interview over 40 auto executives in China (both Chinese and foreign-born) and even bought two Chinese vehicles from Geely and Great Wall. Warburton had them shipped to Europe, where they were taken to a test track, driven extensively and then taken apart by engineers and automotive consultants. And it was far from pretty.Warburton and his gang have assembled an epic 200-plus page report that is one part primer on product development, one part spotter’s guide to the Chinese domestic car industry and one part road test feature that rivals anything out of the buff books or Consumer Reports. It is dense, fact-filled and will take a few solid hours to read and absorb.The first 64 pages are devoted to the ins-and-outs of the Chinese auto industry. Warburton deftly takes us through the various players and their broken-English monikers (Great Wall, Chery, Brilliance and the like) along with thorough … [Read more...] about EXCLUSIVE: Bernstein Research Literally Dissects Chinese Cars, Auto Industry In 200-Page Report
