2006 Ford Explorer Pointers
Photo 2). Another change for the 4.6L in 2006 is that it no longer uses a knock sensor. Both, the 4.0L and the 4.6L use a PCM-controlled heated PCV valve. The PCV valve on the 4.0L SOHC engine is located in the back of the left valve cover, mounted horizontally, and is well hidden from

Service Guide: F-Series New Model 2004
A bold new look and some subtle changes probably best describe the 2004-and-up Ford F150. To the technician, it is the subtle changes that he or she needs to be aware of. Starting with the 2004 model year, Ford launched a new body style for the F150. The new body style truck is a new
Selling Services: Bleeding ABS Brakes after Component Replacement
Bleeding the brakes after brake components have been replaced is a step you don’t want to skip if you want a firm brake pedal. Air trapped in the lines, calipers or wheel cylinders will make the pedal feel soft and spongy. Air is compressible, so when the brakes are applied any air bubbles in the
Engineering: What Goes Up, Must Come Down!
Validating that the vehicle brake system is capable of getting the vehicle down a mountain is one of the major tests that occurs during the development and “prove-out” of the vehicle. In most cases, the manufacturer or the brake system supplier will test the vehicle on the road. This is also where a lot of
Doing the ‘Complete’ Brake Job
Brake work continues to be a solid service opportunity for independent repair shops because brakes are items that inevitably wear out. Disc brake pads need to be replaced, and the rotors usually need to be turned or replaced. The front brakes do the most of the braking, so they receive most of the attention when
Subaru Brake System Service
Over the last 25 years or so, Subaru has been the top- selling all-wheel-drive car here in the Pacific Northwest. For beachcombers and skiers alike, as well as rock hounds and hikers, having all-wheel drive is a big plus. Stop-and-go commuting, and difficult mountain driving take their toll on both drivers and vehicles. Of all
What Were They thinking?
hey pick the size of the parts? What prevented them from making them bigger? What kind of tests did the parts and the vehicle have to endure to be judged ready for the market? These are all questions that go into the design of the brake system for the vehicle. These decisions are the responsibility
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
Wheel Speed Sensors
According to a recent BRAKE & FRONT END survey, the most commonly replaced ABS items are wheel speed sensors and wheel bearing hub units with wheel speed sensors. Pulling a wheel speed sensor code does not mean that you should immediately pull and replace the sensor. If you do not confirm the source of the
Diagnostics Through CAN Networks
Since model year 2003, a growing number of domestic and import vehicles have been built with a new onboard communications protocol called CAN (Controller Area Network). CAN is essentially an engineering standard for how computers and modules talk to one another via the serial data bus in a vehicle’s wiring system. It’s a high speed
A Brief History
In 1931, people thought Edward S. Babcox was insane for launching a magazine in the middle of the great depression. But, 75 years and almost 900 issues later, BRAKE & FRONT END is still going strong. For the past few months, I have been reading back issues of BRAKE & FRONT END non-stop. In musty
