September 18th, 2016 by

UNEVEN BRAKING Back when most automobiles were outfitted with drum brakes, uneven braking (often referred to as “brake pull”) was quite common. But even though self-adjusting disc brakes have become more the rule than the exception, uneven braking can still be a problem. Although self-adjusting disc brakes are supposed to automatically compensate for pad wear,

WHEEL ALIGNMENT Steps in a wheel alignment A wheel alignment may begin by adjusting the “toe,” which is the tilt of the wheels toward or away from one another when viewed from above. Tires that “toe-in” point toward one another while tires that “toe-out” point away from each other. Proper toe adjustment minimizes wear. Then,

Piston Ring Maintenance

PISTON RING MAINTENANCE Piston rings maintain combustion pressure in the cylinder and prevent oil from seeping into the combustion chamber. Ring failure results in white exhaust smoke excessive oil consumption compromised performance To verify the need for piston ring maintenance, the technician uses a compression tester to check for low compression readings. The technician may

Cooling System Problems

TURBOCHARGED MAINTENANCE Energy Requirements As automobile manufacturers look to meet government energy requirements without compromising engine performance, they are increasingly embracing turbocharging. According to the estimate of a leading turbo supplier, 39 percent of all the vehicles sold in North America will have turbocharged engines by 2020, which is up from 23 percent in 2015.

Mass Airflow Sensor

MASS AIRFLOW SENSOR When you experience vehicle symptoms such as: Engine hesitation Stalling Jerking upon acceleration Poor fuel economy Compromised performance the problem may be a contaminated mass airflow sensor. This instrument measures the volume of air entering the engine. This information is needed by the Engine Control Unit (ECU).  It calculates how much fuel should be delivered to each cylinder

Sizing Automotive Tires

SIZING AUTOMOTIVE TIRES When sizing automotive tires, the string of numbers and letters on the sidewalls of automobile tires contains all the information you need to find replacement tires. The alpha-numeric code on the tire of the typical family sedan begins with “P,” which stands for “passenger” car. The following number (such as 215) indicates the

Dragging Brakes

May 30th, 2016 by

DRAGGING BRAKES “Dragging brakes” is a term that refers to brakes that remain partially applied even though pressure is not being exerted on the brake pedal. One of the likely causes of dragging brakes is contaminated brake fluid, which usually occurs as a result of openings around rubber seals or tiny breaks in flexible brake
