Complete brake kits – comprehensive solution for your car
The best used brake parts – discs, pads and pumps with proven durability
Have you ever considered how crucial your braking system is to your safety on the road ? It's responsible for effectively stopping your vehicle in every situation, providing you with confidence and control while driving. At Global Parts, we offer a wide range of braking parts, perfectly matched to brands like BMW , Audi , Volkswagen , Mercedes , and Mini . Whether you need brake discs, pads, hoses, or calipers, you'll find everything you need to keep your car running smoothly and safely. A car's braking system can be divided into several main subsystems: hydraulic (pumps, hoses, calipers), disc-and-pad (brake discs and pads), and electronic braking systems (ABS, ESP). Brake discs typically range from 240 mm to 380 mm in diameter, and the pads generate braking power depending on the contact area and material (ceramic, semi-metallic, organic). High-quality braking components can last up to 100,000 km under normal operating conditions.
How does a 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 ensure effective braking:
- Other ABS parts – 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 – Components used in older braking systems, ensuring effective braking of the rear axle.
- Brake pumps – They are responsible for generating pressure in the braking system and ensuring the effective operation of the brakes.
- Brake cables – Used in hand brake systems, ensuring wheel locking when the handbrake is applied.
- Brake shoes – Key components of the drum braking system, pressed against the inner walls of the drum.
- Complete brake kits – Complete sets of components for braking system regeneration.
- Brake pad wear sensor – Electronic components that monitor the condition of the pads and inform when they need to be replaced.
- Servos and brake force correctors – Systems that support the force applied to the brake pedal, improving braking efficiency.
- ABS and ESP system – Electronic systems that ensure vehicle stability and eliminate skidding during 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 rotational 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 working in conjunction with the brake pads.
- Brake pads – Elements that come into direct contact with the discs, generating friction and allowing the vehicle to stop.
- Brake hoses – They 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.
Compatibility and braking system parameters table
| Braking system element | Typical dimensions/parameters | Model Compatibility | Practical notes |
|---|---|---|---|
| Brake discs | Ø 240–380 mm, thickness 20–32 mm | BMW 3/5, Audi A4/A6, VW Passat | Ventilated or solid, depending on the model |
| Brake pads | Contact area 80–120 cm² | Mercedes C/E, Mini Cooper | Ceramic or semi-metallic |
| Brake pumps | Working pressure 70–100 bar | Audi A4, VW Golf | Suitable for ABS/ESP systems |
| Brake calipers | Piston diameter 35–60 mm | BMW 1/3/5, Mercedes C | Acceptable for various types of discs |
Why is it worth investing in high-quality braking system parts?
Choosing the right braking system parts is crucial for 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 ensure faster braking system response, which is crucial in emergency situations.
- Longevity – Thanks to the use of proven technologies, braking system components operate reliably for a long time. At the Global Parts store you will find original used car parts that have undergone thorough quality checks and meet the highest safety standards.
Definitions and benefits of braking systems
The braking system consists of hydraulic and mechanical components that work together to convert pedal force into braking force at the wheels. Using high-quality brake discs and pads allows for:
- Braking distances are reduced by up to 15–20% compared to lower quality parts.
- Reducing wear on other system components, e.g. suspension or tires.
- Compatibility with ABS/ESP systems, which increases safety during sudden braking.
How to choose the right braking system parts?
When deciding to purchase parts for the braking system, it is worth paying attention to several key aspects:
- Vehicle-specific fit – The braking system must be perfectly matched to the specific model, whether it's a BMW , Audi , Volkswagen , Mercedes , or Mini . When you choose parts from the Global Parts automotive store, you can be sure to find components that are perfectly matched to your car.
- Technical condition – In the case of used car parts It is crucial that they are fully functional and reliable.
- Material Type – For example, brake discs can be made of cast iron or composites, while brake pads can be made of a ceramic or metal compound. Choosing the right material affects the performance and durability of the system.
Brake system assembly and adjustment procedures
When replacing brake system parts, the following steps are important:
- Verification of disc diameter and thickness and pad type.
- Checking the compatibility of the calipers with the ABS/ESP system.
- Installation of brake lines and hoses in accordance with the manufacturer's markings.
- Bleed the system after replacement to ensure optimal braking power.
Why choose used braking system parts?
Used car parts are a solution that combines high quality with cost-effectiveness. Why is it worth considering?
- Lower costs – Used brake discs and pads often offer the same quality as new, but at a much lower price.
- Ecology – By choosing used car parts, you contribute to recycling and reduce the amount of waste in the environment.
- Wide range – At Global Parts you will find everything you need – from brake hoses to calipers.
How to take care of your vehicle's braking system?
Regularly checking and maintaining your braking system is key to safe driving. Here are some tips:
- Check the condition of your brake discs and pads at least once a year or every time you change your tires.
- Change the brake fluid regularly to avoid corrosion inside the lines.
- Monitor any alarming signals, such as squeaking, vibrations or extended braking times – these may indicate wear of system components. If you notice any problems, don't delay replacing the part. You'll find used car parts at Global Parts. that will help you quickly restore the full functionality of your braking system.
FAQ – Frequently asked questions about braking systems
