Car Brake Pads
Car brake pads are usually made from iron, copper, steel and graphite all mixed and together and bonded to form the pad material. When you put your foot on the brake the brake pad is pressed against to the break disc to slow you down and help you stop. These component parts are designed to wear down over time and therefore need to be regularly checked to ensure there is enough pad left to help you stop safely. Brake pad checks are normally carried out as part of a normal car service. However, if you suspect there is something wrong with your brakes then you should get them checked immediately.
Car Brake Disc
The brake disc is usually made of cast iron and is connected to the axle of the car. The disc itself is normally hard wearing however it can become warped/distorted if the brake pads have been allowed to wear down too much. In this instance both the pads and the disc will need to be replaced and you would normally replace them in pairs. (Both fronts / both rears)
If the brake disc has warped then new brake pads won’t effectively work properly when pushed against the surface as it is no longer flat.
Car Brake Fluid
Car brake fluid provides the necessary pressure in the hydraulic breaking system. It has to be maintained and topped up regularly to ensure the brakes on your car continue to work correctly.
There is a small brake fluid reservoir in the engine compartment under the bonnet. Markers on the side of the reservoir indicate the current level of the fluid in the system.
The brake fluid is checked when you have a normal car service and topped up if required. As the system works under a pressurised system then it is important that the brakes are ‘bled’ when replacing brake fluid to ensure no air exists within the braking system.
