Brake Job: 2002-2008 Ford Explorer
The Ford Explorer’s brake system is a relatively robust and trouble-free system. But, that doesn’t mean something can’t go wrong.
Electronic Brake Distribution: Emerging Technology Offers Service Opportunities
Say goodbye to mechanical brake proportioning valves, and say hello to Electronic Brake Distribution (EBD). This new technology is yet another electronic enhancement that’s being added to many late-model vehicles. With conventional hydraulic brakes, a mechanical proportioning valve is used to reduce pressure to the rear wheels when the brakes are applied. Inside the proportioning

Tech Tip: Brake Lathes Continue to be a Profit Center for Busy Shops
A brake lathe has long been an indispensable piece of equipment for shops that do brake work. A bench lathe is necessary to resurface rotors and drums. An on-car lathe is also a great tool for turning troublesome rotors on vehicles that are sensitive to rotor runout issues, and those with captured rotors. But with cheap offshore rotors flooding the aftermarket, and some new cars now being equipped with lightweight rotors that are too thin to turn, you may be questioning the need for a brake lathe ….

Tech Tip: What Should a Technician Know When Ordering Rotors?
It is tough for a technician to know what they are getting when they buy a rotor. According to a recent U.S. International Trade Commission report, 80% of the rotors sold today are made in a country other than the United States. If the technician or counterman is only going on the price on the screen, it is difficult to pick the best rotor ….
Tech Tip: Rotor Runout Checklist
The vehicle owner may say that under light braking the vehicle pulses to a stop, or under heavy braking the vehicle shudders. Technical service bulletins (TSBs) often describe these symptoms as a "judder." There are only two causes for judder – lateral runout and disc thickness variation on the rotor’s friction surface. What could have caused the lateral runout? The causes of the condition range from ….

Tech Tip: Brake Burnishing Procedures for New Brake Pads or Shoes
After every brake job the technician should first confirm that he has a good brake pedal by gently stroking the pedal to move the wheel cylinders and caliper pistons back out to the normal position. After confirming a good pedal, the follow burnish procedure should be used during the test drive ….
Tech Tip: Lower Mass Brake Rotor Causing Noise, Fade and Failure Problems
If a customer complains of noisy brakes, increased stopping distances and pedal pulsation after brake rotors were replaced or machined, the rotors may be the source of the problem. It’s easy to blame the pads or brake hardware, but technicians need to look at the rotor. Affinia Global Brake & Chassis discovered during a recent benchmarking study of the competition that some rotor companies have reduced their ….
Tech Tip: When Drums Lock Up
Drum brakes that occasionally lock up should not be ignored, but a relatively recent drum-brake-lockup condition is often dismissed because it doesn’t happen all the time. Since it’s usually not present by the time a technician gets to look for its cause, it’s often tempting to suggest the customer simply live with it ….
The 3rd (or 4th) Pedal
When was the last time you used your park brake? During a training seminar recently filled with brake people I got a lot of blank stares. Ok, rule number one don’t ask open ended questions right after lunch. Rephrasing, how many of you used your park brake when you parked the car today, one hand
