Brake Pads: Understanding Friction And Formulations
How the components in the friction material shear, break and interact during braking can determine a pad’s friction level, noise and wear characteristics.
Understanding Wheel Bearing Seals
A seal must always be installed so that the sealing lip is facing the fluid to be sealed. This is because the lip is made so that pressure applied to it from the “wet” side of the seal will tend to increase the pressure the lip applies to the shaft. If the seal is installed backwards, pressure acting on the “wrong” side of the lip will cause it to lift from the shaft, resulting in leakage. On most seals, the correct side is obvious; however, on others it is not.

Dealing With Remanufactured Transmissions
When replacing a transmission, you have many options. Remanufactured transmissions are disassembled and rebuilt in a factory environment. Rebuilt transmissions are those that are characteristically cleaned, inspected and wear items like clutch plates and seals are replaced. These transmissions usually come with only a short-term warranty. Used or salvage transmissions can be pulled from anywhere
Gonzo’s Toolbox: Abbreviations
One of the techs came into the office some time ago to explain some crazy readings he was getting after hooking up to the DLC with the NGS. As he was explaining the problem, a very inquisitive customer was sitting at the counter waiting for an LOF. The mechanic and I discussed the test results
