⚡ At a Glance
- • Inner diameter: 25.4 mm bore, machined for dimensional accuracy
- • Best for: Owners of BMW X3 (E83/LCI) and 5 Series (E60/E61) needing direct replacements
- • Not ideal for: Vehicles outside the listed BMW compatibility unless VIN confirms fit
Aluminium master brake cylinder with a 25.4 mm inner diameter for hydraulic systems. Intended as an original febi bilstein replacement compatible with selected BMW X3 and 5 Series variants.
Consistent Braking Feel – With OE-comparable bore diameter
A 25.4 mm inner diameter is specified to match piston and bore tolerances, supporting steady hydraulic pressure and repeatable piston travel. Precision machining of the bore helps maintain consistent fluid dynamics under braking.
Predictable pedal response and steady braking modulation for compatible BMW models, reducing the chance of uneven braking behaviour during daily driving or heavier use.
Lightweight Assembly – Thanks to aluminium construction
Aluminium construction and a recorded weight of 0.701 kg indicate a lighter component compared with heavier materials, without adding unnecessary mass. The material selection supports handling during installation and thermal characteristics under normal operating conditions.
Easier handling for repairs and less added mass to the vehicle's assembly, helping maintain original vehicle dynamics when replacing the master cylinder.
Direct-Reference Fitment – With OEM cross-reference number
An OE reference is provided for comparison, BMW: 34 33 6 786 629, to assist parts identification and matching. The listing advises using vehicle identification to confirm compatibility and observe any restrictions.
Simplifies parts matching for BMW X3 and 5 Series owners when confirming compatibility via VIN, helping to avoid incorrect purchases and repeat returns.
