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. A brake pad may require up to 20 different raw materials. Some raw components of a friction material are abrasive, while other components lubricate. Some components, like structural fibers and resins, hold the pad together, while other components tune the friction levels through various temperature ranges.

BMW Electric Water Pump Replacement

We recently had a 2007 BMW Z4 with the N52 engine in the shop. When diagnosing a faulty electric water pump, the first thing that needs to be done is to verify if there are any water pump-related diagnostic codes. There’s a very good chance there will be some.

Air Ride Dryer Diagnostics

The dryer on most air ride systems contains a moisture-absorbing desiccant, such as silica or specialized clay. All desiccants have a limited lifespan; they can absorb only a certain amount of water.
