Millway Motorsport Stainless Steel Brake Caliper Pistons (Set of 8) for BMW F2X M135i M140i M235i M240i & F8X M2 M3 M4 - Brembo Blue M Front Calipers - Track/Race Upgrade

Transform your BMW braking with Millway stainless calliper pistons engineered for hard use on circuit and fast road. These diamond polished SS pistons replace the stock alloy items in the blue BMW M Performance four-piston front callipers, delivering cooler operation, stronger pedal feel and repeatable stopping power when driven in anger.

Why this piston set is a must-have for serious drivers

• Stainless construction with a mirror-smooth finish for ultra-low stiction and long service life.
• Lower thermal conductivity than aluminium to curb heat soak into pads, fluid and seals, helping fight fade and soft pedal.
• Air-gap face design promotes pad interface cooling for consistent performance over long stints.
• Direct swap for the OE pistons in the blue BMW M Performance/Brembo 4-pot front callipers used across popular F-series M models.
• Proven by us on our own builds and by our track-day customers who demand reliable braking lap after lap.

Compatible BMW applications

Front axle calipers commonly fitted to:

• F2X M135i, M140i, M235i, M240i
• F8X M2, M3, M4
• Also suitable for other BMWs using the same blue M Performance front 4-piston Brembo calliper

Good to know before you buy

• Track-focused design without dust boots. Regular maintenance recommended for vehicles used year-round.
• Supplied as an 8-piece piston set to service both front callipers.
• If you are unsure about your calliper type, contact us and we will confirm compatibility before you order.
