What is Leaking From My Car?

What is Leaking From My Car?

              At some point, we have all experienced the fear of unknown fluids under the car. When this happens, you’re probably going to worry about what fluid is leaking and what the newfound leak means for your day. You might worry if your car is safe to drive, and how much the repairs will cost. Before you get too worried, let's get an idea of how to identify the fluid leaking from your car.  First of all, let's break the fluids down into two groups; oil-based and water-based fluids. The oil-based fluid category will include Motor oil, Transmission Fluid, Differential Fluid, Power Steering Fluid, Brake Fluid, and Fuel. To tell the difference most oil-based fluids will leave a rainbow on wet surfaces and have a noticeably oily feel.  To help you further determine the fluid in question see if you can tell the color and location of the fluid.         Fuel ... read more

Wheel Cylinder

Wheel Cylinder

What is a Wheel Cylinder? The wheel cylinder is the hydraulic component that actuates the brake shoes in a drum brake assembly. Hydraulic pressure from the master cylinder pushes the pistons outward moving the semi-circular brake shoe in contact with the brake drum. This contact creates the friction that slows your vehicle. Wheel cylinders are only used in drum brake equipped vehicles and therefore are becoming less commonplace. The most common failure of a wheel cylinder is leakage. Over time the wheel cylinder piston seals will deteriorate and begin to allow fluid to pass. To check for wheel cylinder leakage the dust boot is opened to inspect. As seen in the figure the red arrow points to fluid that has bypassed the seal and filled in behind the dust boot. This wheel cylinder will require replacement. After the new cylinder is installed the braking system will be refilled and the air removed through the bleeding procedure. A wheel cylinder replacement is the perfect time to service t ... read more

What is a brake caliper?

What is a brake caliper? A "brake caliper" is a component of your vehicles "disc brake" system. The brake caliper is a hydraulic component that applies pressure to the brake pads against the brake rotor and in turn slows down the wheel and ultimately the vehicle. Brake calipers are situated in a harsh environment exposed to road grime, water dust dirt, and salt with a wide range of temperatures. The caliper is filled with "brake fluid".#brakecaliper #brakes #brakefluid
