OEM Brake Master Cylinder - E28 / E24 1983 and Up - 34311155270

This part is listed by BMW as BMW part number 34311155270 (34-31-1-155-270) and is described as Brake Master Cylinder for E28 528e, 533i, 535i, M5 (1983, 1984, 1985, 1986, 1987, 1988) and E24 633CSi, 635CSi, M6 (1983, 1984, 1985, 1986, 1987, 1988, 1989).

This OEM Ate Brake Master Cylinder is a high-quality replacement for your old, failing master cylinder on the classic E28 5 series or E24 6 series. The master cylinder controls the distribution of brake fluid through your entire braking system, so even a small leak from a failing part can cause poor brake pedal feel and inaccurate brake modulation. 

If you've found your E24 or E28 brake pedal travel to be getting longer, particularly when sustained pressure is applied, a thorough inspection and likely replacement is highly recommended.

• OEM quality and fitment
• Ideal for rejuvenating your braking system
• Key safety component for promoting accurate pedal feel
