Introducing a budget friendly big brake kit from Brembo - The B-M4

The B-M4 represents the latest in Brembo's experience in caliper design. The B-M4 kit includes new 345mm one-piece rotors, along with pads, lines and all hardware necessary for installation.

Quick Info:

  • Caliper Body: Cast Monoblock Radial Mount
  • Caliper Piston Configuration: 4 Piston
  • Caliper Piston Design And Insert Type: Inner Pressure Seal / OEM Approved Dust Boot
  • Size: 345x30mm (13.6'')
  • Rotor Design: Once-piece (drilled or type 3 patterns available)
  • Rotor Vane Design: Vented Curved 48 Vane
  • All necessary hardware included

All new braking technology

The B-M4 is manufactured using a new, innovative 4D technology casting process, and is the first time this process has been used for automotive calipers. This casting process uses a technology that enables Brembo to engineer a design completely different from what is usually seen in the caliper market. With this technology, the casted caliper has technical features commonly used in racing billet or forged calipers. The B-M4 is casted with an internal fluid line versus the more conventional rigid pipe connections. The one non-visible bleeding screw allows for more safety and freedom in the design since it is better integrated into the overall design. The B-M4 is the most efficient body architecture and style and designed without constrains on the outboard caliper manufactured by traditional molds. 

For the street or track

If you have a modified street or track driven vehicle, you've probably noticed that your stock brakes just aren't keeping up with the increased speed. Developed as the next step beyond basic pad and rotor upgrades, the Brembo B-M4 4 piston brake kit is designed to give you a substantial increase in overall braking performance. Decreased stopping distances, better heat management and significantly better resistance to brake fade are all characteristics of this great kit.

Fitment Template:

Please note that while the brake calipers and rotors will physically install onto models that came equipped with 340mm front brakes (Performance Pack GTI, Golf R, S3, TTS), due to the difference in the size of the master cylinder, this kit should not be used with those models.
