What Is a Brake Slave Cylinder?

Part of the braking system, a brake slave cylinder is an assembly housing a piston that compresses and releases the brake shoes or pads in hydraulic brakes. If your slave cylinder is damaged, it likely will allow the hydraulic fluid or brake fluid to leak. This will result in decreased braking force, including a possible loss of braking.

What Is a Fuel Filter?

A fuel filter is an integral component of a vehicle’s fuel system, protecting it from contaminants and allowing the engine to run cleanly and efficiently. The fuel filter screens dirt, sediment, contaminants, and even rust particles out of the fuel, preventing them from entering the injectors or other parts of the engine where they could cause damage. Dirt and debris can cause unnecessary wear and tear on injectors and other components.

A car's water pump
General

What Is Water Pump Replacement?

A water pump replacement is needed when the water pump stops circulating or is leaking coolant. The water pump is a mechanical device attached to the engine that forces liquid coolant through the hoses, passageways, and radiators to move heat in the system. In most engines, a belt connects the pump and the crankshaft, transferring rotational power. Water pump failure can lead to overheating, leading to engine failure, so when a water pump goes bad, it must be repaired or replaced.

Timing belt
General

What Is Timing Belt Replacement?

The timing belt, or “cambelt,” synchronizes the rotation of the camshaft and the crankshaft and is an item that must be removed and replaced with a new timing belt on some cars in accordance with the manufacturer’s specifications. The camshaft opens and closes the valves that let air into the combustion chamber. The crankshaft causes the pistons to move up and down. The timing belt turns the crankshaft and coordinates the firing of the pistons, which develops an engine’s power.

spark plugs
General

What Is Spark Plug Replacement?

Spark plugs are wear items in an internal combustion engine (ICE) and must be removed and replaced periodically. Spark plug replacement is necessary to keep your car firing on all cylinders — literally. Spark plugs ignite the fuel-air mixture in the combustion chamber, which creates the engine’s power. Most vehicles have one spark plug per cylinder. Failure of timely spark plug replacement can cause your car to stall, become unable to start, or its engine to misfire (knocking sound), all of which can lead to engine damage.

Brake fluid reservoir.
General

What Is Fluid Replacement?

Fluid replacement in a car goes beyond oil changes and covers fluids that allow the transmission, radiator (coolant), and brakes to perform properly. These fluids need replacement in manufacturer-recommended service intervals, usually based on the vehicle’s accrued mileage. Sometimes, these replacements are prompted by a breakdown or repair.

What Are Brake Lines?

Brake lines are hoses that transfer brake fluid from a reservoir through a pump or modulator to a brake master cylinder to create hydraulic pressure to push the brake pads against the disc rotor or drum brake, slowing or stopping the vehicle. If the brake fluid becomes depleted or air enters the brake lines, the brake response can weaken and the brake lines will need to be bled or flushed. Hire a certified mechanic to perform this service, as special equipment is often required.

What Is an Alternator Replacement?

An alternator replacement is a physical action on an engine component, removing it and putting in a new or reconditioned unit to take its place and perform its function. The alternator is the belt-driven unit that charges the 12-volt battery as the engine runs. If you’re having trouble starting your car, you may need an alternator replacement. A malfunctioning alternator can cause underperforming lights, instruments, accessories, and a dead battery.

A dirty air filter held over a car engine during general auto maintenance.
General

What Is an Air Filter?

An air filter is an element in the intake path that traps debris and other particles from being sucked into a vehicle’s internal combustion engine (ICE), protecting the engine’s inner parts from premature wear or damage. Air filters must be replaced regularly, a simple DIY project on most vehicles.

Brake Caliper
General

What Is a Brake Caliper?

A brake caliper is an assembly, part of a disc brake system. The caliper mounts to the vehicle and frames the rotor, acting as a clamp. The rotor spins until the caliper actuates, using a piston (or multiple pistons) to press the brake pads against the rotor, slowing it down with friction.
