Parts for your 2007 Honda Civic-Cluth slave cylinder

2007 Honda Civic cluth-slave-cylinder

Technical sources including the Honda Civic 2006–2011 Factory Service Manual (Helm Inc., Clutch section), Honda Genuine Parts Catalogue (EPC), and common workshop references (Haynes/Autodata/Mitchell1) confirm that 2007 Honda Civic models equipped with a manual transmission use a hydraulic cluth-slave-cylinder (clutch slave cylinder). It’s an external unit mounted on the gearbox that works with the clutch master cylinder to engage and disengage the clutch. Civic variants with automatic transmissions don’t use a cluth-slave-cylinder at all, as they have a torque converter and no clutch pedal.

On a manual 2007 Civic, the cluth-slave-cylinder converts hydraulic pressure from the master cylinder into movement at the release fork, which in turn operates the pressure plate. It’s a compact, hardworking part that lives on the bellhousing and shares brake fluid from the clutch/brake reservoir. Keeping it healthy keeps shifts clean and pedal feel consistent, especially in stop–start Aussie and Kiwi traffic.

Typical signs the cluth-slave-cylinder needs attention include:

• Soft or sinking clutch pedal, or engagement point moving higher or lower.
• Difficulty selecting gears, especially reverse or first when stationary.
• Visible fluid seepage around the slave or a dropping fluid level in the reservoir.

As part of routine servicing, it’s smart to refresh the hydraulic fluid every 2 years or around 40,000 km (whichever comes first), matching the brake fluid interval in most maintenance schedules. Use quality DOT 3 or DOT 4 fluid meeting Honda specs. After any hydraulic work, bleed the system properly: top the reservoir, attach a clear hose to the bleeder on the slave, press and hold the pedal, crack the bleeder to expel air, then close and repeat until only clean, bubble‑free fluid flows. Don’t let the reservoir run low, and keep fluid off paintwork.

Replacing a tired cluth-slave-cylinder is straightforward for a competent home mechanic. Use a line spanner on the hydraulic fitting to avoid rounding, swap the unit, torque the mounting bolts to the factory spec (refer to the Honda manual), and bleed thoroughly. It’s also a good time to inspect the rubber clutch hose, the master cylinder for internal bypassing, and the release fork boot. Quality OEM‑equivalent parts and fresh fluid will restore pedal feel and help the clutch last longer—no dramas.

Popular questions

Does every 2007 Honda Civic have a cluth-slave-cylinder?
Manual models do—both the 1.8L and the 2.0L/Si use a hydraulic system with an external slave cylinder. Automatic Civics don’t have one because there’s no manual clutch to operate. If there’s a clutch pedal, there’s a slave cylinder fitted.

How often should the cluth-slave-cylinder fluid be changed?
Follow the brake fluid interval: typically every 2 years or about 40,000 km. The clutch shares the same reservoir and fluid type, so flushing keeps the hydraulics clean, prevents internal corrosion, and maintains a consistent pedal.

Can a failing cluth-slave-cylinder damage the clutch?
Indirectly, yes. If the slave can’t fully disengage the clutch, shifts get crunchy and the disc can drag, if it can’t fully engage, the clutch can slip and overheat. Sorting the hydraulic issue early protects the pressure plate, disc, and release bearing.
