Recommended Brake Caliper Related Parts

A brake caliper is used in a disc brake system and houses pistons and brake pads, which work together in slowing down the vehicle by creating friction against the brake rotors. The brake caliper acts as a bracket and holds the brake pads on either side of the rotor. The caliper also comprises pistons that act under hydraulic pressure and push the brake pads. Although most of the brake calipers consist of single or double pistons, calipers with more (four, six or more) pistons are also available depending on the braking force required. As you step on the brake pedal, the master cylinder pushes the brake fluid through the brake lines into the brake caliper, which forces the pistons in the caliper to push the brake pads against the brake rotor. 

1. Brake Pads

What Are Brake Pads?

Brake pads are used in disc brake systems and are made from a thick layer of steel with friction linings on one side. The brake pads are attached to the brake caliper, which houses pistons that push the brake pads against the rotor under hydraulic action. As the brake pads rub against the brake rotors, a lot of heat is generated. Based on the type of friction linings, different brake pads are used including ceramic brake pads, semi-metallic brake pads, etc. These metals and synthetic materials used on brake pads allow them to withstand the friction generated by the braking action and make them resistant to thermal damage.

When Should I Replace My Brake Pads?

Every time the brakes are engaged in a vehicle, a small amount of friction material wears out from the brake pads. Over time, the friction material becomes thinner and exposes the steel plates to which the fiction lining is attached. However, the life of these brake pads depends on several factors like driving style, vehicle type, load carried, driving conditions, etc. When your brake pads wear out, you'll likely experience some symptoms like squealing or screeching noises, deep metallic grinding or growling, and a longer stopping distance. Modern vehicles are equipped with brake pad wear indicator lights, which will come up on the console when the brake pads are too thin. Another way to check is to visually inspect your brake pads for excessive wear and if they are less than 1/4 inch thick (approximately 3mm), then you are probably due for new brake pads. 


2. Front Caliper Bolt Or Pin

What Are Caliper Bolt And Pins?

The brake caliper has round metal pins near the brake piston assembly. They are also known as guide pins because they decide the proper angle at which the brake pads meet the rotor. Brake caliper guide pins keep the brake pads aligned and are usually two in quantity in most calipers. Brake caliper pins are covered with pin boots that hold the grease inside for lubrication and keep the water, sand, and dust away. Brake caliper bolts are simple components that hold your calipers onto your vehicle. They are also called caliper bracket bolts because they are attached to the bracket of the caliper and keep the caliper secured against the spindle or steering knuckle.

When Should I Replace My Caliper Bolt And Pins?

It's important to check your caliper pins while replacing your brake pads. Check the guide pins for signs of corrosion or lack of lubrication. Often the pins get stuck, can't be removed, and do not go all the way. This happens due to dirt, moisture, and a torn pin boot which is not able to keep the contaminants off. This can cause caliper binding and can lead to premature failure and uneven brake wear. If you are experiencing grinding noises or brakes are sticking or grabbing, then your guide pins might be faulty and require replacement. Caliper bolts, on the other hand, can also fail with time due to prolonged exposure to external conditions and elements. They can get stuck due to over-tightening or get too old. Therefore, replacing your old caliper bolts and pins is a good idea while replacing caliper or brake pads. It makes the brake job complete and ensures a properly functioning braking system.


3. Hydraulic Brake Line

What Is A Hydraulic Brake Line?

Brake lines serve the simple purpose of transporting the brake fluid under pressure from the master cylinder to the brake calipers. The pressure offered by the brake fluid pushes the pistons in the caliper outwards against the brake pads to stop the brake rotor. Brake lines are made from different materials like steel, stainless steel, nickel-copper, etc. These materials allow the brake lines to sustain high pressures and ensure efficient transfer of pedal effort to the brake pads.

When Should I Replace My Hydraulic Brake Line?

Brake lines are designed to be durable and to withstand tough conditions and elements like moisture, road salt, rocks, dust and grime. These elements can lead to corrosion and cause the brake lines to weaken with time. Once the brake lines begin to fail, your braking system will also fail causing several issues with your vehicle. Some major symptoms that indicate a failing brake line are leaking brake fluid due to a line failure and a brake warning light on the console. Other than these symptoms, brake lines can also be inspected visually for signs of corrosion build-up which can cause the brake line to rust, leak, or break. If you witness these symptoms, then your brake lines must be failing and need to be checked for potential issues. You should not overlook these signs and get your brake lines replaced to avoid a mishap in an event of a brake failure.

4.Brake Caliper Cover

What Is A Brake Caliper Cover?

Brake caliper covers are metal or plastic components designed to clip on your calipers and are usually used by vehicle owners to customize the vehicle. Brake calipers do more than just enhance the look of the vehicle and also help to keep the wheels clean by keeping the brake dust away. Caliper covers can also act as a heat sink for the brake calipers by drawing the heat away, therefore, reducing the chances of brake fade, improving the life of your braking system. They are made from different materials like aluminum, stainless steel, and ABS plastic treated with high-heat silicone that allows them to handle extreme conditions.
