FAQs
What is the bore diameter of the BCM159?
The BCM159 has an inner diameter of 19.05 mm.
Which vehicles is this master cylinder compatible with?
It is designed for various Ford Transit models. Please verify your specific model year and chassis number using a fitment tool before purchasing.
Does this unit replace Ford OEM part 1727157?
Yes, it is a direct replacement for Ford part numbers 1727157, 1762805, and CC117A543AC.
Can I install this myself without professional tools?
While some users perform this at home, it requires specific tools to disconnect hydraulic lines and the expertise to bleed the system of air, which is essential for safety.
What kind of fluid should I use with this cylinder?
Always use the brake/clutch fluid type recommended in your Ford Transit owner's manual to ensure seal compatibility.
Why is it important to bleed the clutch system?
Air is compressible, whereas fluid is not. If air remains in the line, the clutch will not disengage fully, leading to difficult gear shifts and potential transmission damage.
Troubleshooting
Spongy or soft clutch pedal feel after installation
Air is likely trapped in the system; perform a full hydraulic bleed according to the vehicle service manual.
Clutch pedal does not return to the top position
Check for obstructions in the pedal assembly and ensure the master cylinder pushrod is correctly seated.
Visible fluid leaking at the firewall side
Inspect the connection points and line fittings; if the leak is from the cylinder itself, verify the mounting seal is properly seated.

Setup, Compatibility & Care
Installation of the BCM159 should be performed by a qualified mechanic, as it involves opening the hydraulic clutch system. Always use the appropriate brake/clutch fluid as specified by the vehicle manufacturer. After physical installation, the system must be thoroughly bled to remove any trapped air, which is critical for achieving a firm pedal feel. Ensure all hydraulic line fittings are torqued to manufacturer specifications to prevent leaks. Periodically check for fluid dampness around the master cylinder boot during routine vehicle maintenance to ensure the longevity of the component.
