Brake rotors should feel smooth to the touch. If you feel grooves or see ridges on your rotor, it probably needs to be resurfaced. Brake rotors should be measured at every brake pad replacement. If found to be at or below the manufacturer’s minimum thickness specification, they should be replaced or re-machined.
The purpose of the antilock brake system is to prevent the wheels from locking up or skidding during braking. If the brakes lock up, the vehicle takes longer to stop, and the ability to steer the vehicle is greatly diminished. The ABS system prevents wheel lock-up by monitoring each wheel with a wheel speed sensor. When the wheel starts to skid, hydraulic pressure to the brake is temporarily reduced to prevent the wheel from skidding.
All drivers know that to stop a vehicle, you press the brake pedal. But how does the pedal make the vehicle stop? Brake systems slow and stop the vehicle by applying pressure to rotating brake discs and/or brake drums, which are attached to each wheel.
Vehicles with disc brakes.
On vehicles with disc brakes (which is the majority), there is a metal disc called a rotor. When the brakes are applied, the brake pads are forced against the brake rotor, which will slow or stop your vehicle.
Vehicles with brake drums.
The brake drum fits over the brake shoes. When the brakes are applied, the brake shoes are forced against the inside of the brake drum. This causes the brake drum to top rotating, which will slow or stop your vehicle.
Conventional motor oil is a lubricant that is derived directly from crude oil. It has excellent properties that allow it to provide lubrication at high temperatures, as well as maintaining its stability over long periods of time.
Synthetic lubricants are derived from a number of sources, including completely synthetic compounds, petroleum-based products or other organic oils. Synthetic oil differs from conventional oil because of unique polymers added to the base formulation.
Here is a quick overview of the most common advantages that synthetic oils offer over conventional motor oil:
Improved Lubrication – Most synthetic oils have added lubricants that increase the ability of the oil to keep engine parts slick, especially at high temperatures. This decreases wear over the long term and may make your engine last longer.
Better Stability – Synthetic oils are specially engineered to maintain their thickness at higher temperatures and over longer periods of time allowing “oil” to “stick” to engine parts more readily, providing [...]
Oil is the lifeblood of your vehicle. It keeps the many components of the engine working efficiently, and it helps reduce the accumulation of varnish and carbon from collecting on the engine.
The engine can get very hot from the thousands of small explosions taking place every minute; oil helps pull the heat away from the combustion chamber essentially preventing the engine from blowing up.
Heat breaks down oil and it eventually becomes less like liquid and more like sludge that can clog your engine. No matter how good the oil is, eventually it degrades as the additives get used up. Engines are expensive to clean, and replacing a worn-out piston or engine is not an auto repair bill you want to receive.
Getting your oil changed is one of the least expensive auto maintenance service your vehicle needs and plays a critical role in preserving your vehicle and saving you money. To reduce repairs and [...]
