Tech Tip: Solving Common Brake Symptoms With Unique Solutions

Some vehicles have a history of brake-related problems, but there are some unique solutions to resolve those frustrating customer complaints.

Tech Feature: Ford Hybrid Braking

A hybrid vehicle is a different animal than many of us are used to seeing. After all, if the engine of a typical vehicle were to stall out at a traffic light, the driver of that vehicle would know something was wrong with it. If that same vehicle still drove with the engine off, then that would mean they were probably going down hill. But in the hybrid world, that is all normal. Several systems around the vehicle are impacted by two key elements.

Bleeding ABS Brake System: Why Brake Fluid and Lines Degrade

According to R. L. Polk, the average age of the vehicles on U.S. roads was 9.2 years in 2007 with 41 percent of the vehicles 11 years or older. This high median age is a good reason to consider the condition of the brake fluid and bleeding procedures when performing maintenance or repairs. Maintenance or repair of an Anti-lock Brake System (ABS) system can require the opening of the hydraulic system. Any time the hydraulic system is opened, air can be introduced into the lines and components.

Performance Brake Upgrades: Boosting Brake System Performance and Appearance

What type of customer is a likely prospect for brake upgrades? Those who tend to go through brakes rather quickly because of their driving habits, those who own sporty or performance import makes, and especially those who have already replaced their stock wheels with larger diameter aftermarket alloy wheels and low-profile tires.

Master Cylinders: Reliable, Hard-Working Components Still Need Periodic Inspections

If nothing else, modern master cylinders are notable for their long and relatively trouble-free service lives. The modern master cylinder evolved from the single-piston types popularly introduced in the 1930s to the modern dual-piston, dual braking system cylinders in use today. Master cylinders intended for drum brake use contain one or more residual pressure check valves that maintain a slight pressure in the system.

Tech Tip: Inspecting Brake Hydraulics

The first step in checking brake hydraulics is to inspect the fluid level in the master cylinder reservoir. Although many cars incorporate a float mechanism or sensor in the reservoir that turns on a red "Brake" and/or orange "ABS" warning light on the instrument panel when the brake fluid level falls to a dangerous level, never assume that the fluid level sensor is a fail-safe mechanism ….

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

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
