Complete brake kits – comprehensive solution for your car
The best used brake parts – discs, pads and pumps with proven durability
Have you ever wondered how crucial the braking system is for your safety on the road? It is responsible for effectively stopping the vehicle in any situation, ensuring your confidence and control while driving. In the Global Parts automotive store, we offer a wide range of braking system parts, perfectly matched to brands such as BMW, Audi, Volkswagen, Mercedes, or Mini. Regardless of whether you need brake discs, pads, hoses, or calipers – you will find everything necessary here to keep your car running efficiently and safely. The braking system in a car can be divided into several main subsystems: hydraulic (master cylinders, hoses, calipers), disc-pad (brake discs and pads), and electronic braking support systems (ABS, ESP). Brake discs typically have a diameter ranging from 240 mm to 380 mm, and brake pads generate braking force depending on the contact surface and material (ceramic, semi-metallic, organic). High-quality braking system components can last up to 100,000 km under normal operating conditions.
How does the braking system work? Lighting category elements:
- Braking system is one of the most important systems in every car. It consists of several key elements that work together to ensure effective braking:
- Other ABS parts – Components supporting the operation of the ABS system, increasing braking efficiency.

Construction and purpose of the braking system and parts
Braking system and parts are a set of components mounted at the wheels, in the engine compartment, and in the hydraulic installation of the vehicle, whose task is to controlledly reduce speed and stop the car. A typical system includes discs or drums, pads or shoes, calipers, lines, a brake master cylinder, and elements supervising the system's operation. In practice, it is not only the type of part that counts, but also the OEM number, working diameter, mounting side, and compatibility with the equipment version.
Comparison of the most important braking system element groups
| Part group | Basic function | What to check before purchase | Cooperating elements |
|---|---|---|---|
| Discs and drums | Absorb friction force and reduce wheel rotational speed | OEM number, diameter, thickness, solid or ventilated type, axle side | Pads, shoes, hub, disc shield |
| Calipers, pistons, and brackets | Press the friction element against the braking surface | Piston diameter, mounting type, left or right version, presence of carrier | Pads, flexible hoses, bleeder screw, sensors |
| Lines, cylinders, and reservoirs | Transfer brake fluid pressure and control braking force | Connection type, line length, ABS/ESP compatibility, mounting points | Calipers, master cylinder, booster, ABS module |
Characteristics of calipers, lines, and cooperating elements
Brake caliper is an actuator that converts brake fluid pressure into pad pressure against the disc. Its construction includes a body, a piston or pistons, guide pins, seals, and a bleeder screw, and in some versions, also a parking brake mechanism. In the case of parts such as a BMW 15 caliper, you must compare the body marking, mounting side, carrier type, and compatibility with the disc and connection line.
Selecting parts by model, OEM number, and equipment version
The selection of brake parts should start with the OEM number and vehicle data, such as VIN, model year, body type, and engine version. This is especially important when one model was produced with several disc diameters, different calipers, or different ABS controls. In practice, it is also worth comparing the offer with the Suspension, steering system, Gearboxes and drives, and Automotive electrical systems departments, as associated faults can affect the car's behavior during braking.
Installation procedures and post-replacement inspection
Brake system bleeding is a service procedure consisting of removing air from the lines and calipers after replacing parts or fluid. Without proper bleeding, the brake pedal may feel soft, and braking force will be uneven between axles.
