Complete brake kits – comprehensive solution for your car
Best used brake system parts – discs, pads and pumps with proven durability
Have you ever wondered how crucial the braking system is to your safety on the road ? It is responsible for effectively stopping the vehicle in every situation, providing you with confidence and control while driving. At the Global Parts automotive store, we offer a wide range of parts for braking systems, perfectly matched to brands such as BMW , Audi , Volkswagen , Mercedes or Mini . Regardless of whether you need brake discs, pads, lines or calipers - you will find everything you need to make your car run smoothly and safely.
How does the braking system work? Lighting category items:
- The braking system is one of the most important systems in any car. It consists of several key components that work together to provide effective braking:
- Other parts for ABS – Components supporting the operation of the ABS system, increasing braking efficiency.
- Brake hoses, lines and connectors – They are responsible for transporting brake fluid between the pump and the calipers.
- Brake drums – Elements used in older brake systems, ensuring effective braking of the rear axle.
- Brake pumps – They are responsible for generating pressure in the brake system and effective brake operation.
- Brake cables – Used in hand brake systems, ensuring wheel locking when the handbrake is applied.
- Brake shoes – Key components of the drum brake system, pressed against the inner walls of the drum.
- Complete brake kits – Complete sets of components for brake system regeneration.
- Brake pad wear sensor – Electronic components monitoring the condition of the pads and informing when they need to be replaced.
- Servos and brake force correctors – Brake pedal force support systems, improving braking efficiency.
- ABS and ESP system – Electronic systems that ensure vehicle stability and eliminate skidding when braking.
- ABS controllers – Modules controlling the operation of the ABS system, optimizing the braking force on individual wheels.
- ABS speed sensor – Responsible for monitoring wheel speed and transmitting data to the ABS system.
- Other Brake Sensors and Switches – Elements monitoring the pressure and temperature of the braking system, ensuring its efficient operation.
- Brake fluid reservoirs and caps – Containers storing brake fluid and responsible for its proper circulation in the system.
- Brake discs – They are responsible for slowing down the vehicle by cooperating with the brake pads.
- Brake pads – Elements that are in direct contact with the discs, generating friction and allowing the vehicle to stop.
- Brake lines – Carry brake fluid which activates the calipers and pistons.
- Brake calipers – They enable the pads to be pressed against the discs, which is crucial for braking efficiency. A well-functioning braking system not only increases your safety, but also protects other vehicle components from excessive wear.
Why is it worth investing in high-quality braking system parts?
Choosing the right parts for your braking system is key to driving safety and comfort. It's worth choosing components that offer:
- Durability – Brake discs and pads made of high-quality materials are more resistant to overheating and wear.
- Efficiency – Original parts provide faster response of the braking system, which is crucial in emergency situations.
