What it is
This is the genuine Ford OEM clutch master cylinder and pedal assembly for the Focus ST. It's a complete unit — the pedal and master cylinder come together as one assembly, which simplifies replacement and ensures everything is properly matched from the factory.
Part details
- Type: Complete clutch master cylinder and pedal assembly
- Fits: Ford Focus ST 2015–2018
- Genuine Ford OEM part
What it does
The clutch master cylinder converts pedal input into hydraulic pressure, which travels through the clutch line to the slave cylinder and ultimately engages or disengages the clutch. Because this is a combined pedal and master cylinder assembly, it covers failures or wear in either component without needing to source them separately.
Why you might need one
The Focus ST has a known history of clutch master cylinder issues — a spongy or inconsistent pedal feel, difficulty engaging gears, or a pedal that stays on the floor are all common symptoms of a failing unit. Ford updated the design over the production run, so if your 2015–2018 ST is showing these symptoms, replacing the full assembly with a current OEM unit is the recommended fix. Sourcing it as a genuine Ford part ensures you're getting the latest revision rather than an older or lower-spec aftermarket version.
Installation notes
This assembly mounts inside the cabin and connects to the clutch hydraulic line at the firewall. Replacement involves removing the lower dash trim, disconnecting the pushrod from the pedal, unbolting the assembly from the firewall, and bleeding the clutch hydraulic system after installation. It's a moderately involved DIY job but well-documented in the Focus ST community.
Common use cases
- Replacing a spongy, soft, or inconsistent clutch pedal
- Fixing a clutch pedal that sinks to the floor and doesn't return
- Addressing difficulty shifting or fully disengaging the clutch
