Parts for your 2009 Honda Cr-v-Clutch master cylinder

2009 Honda CR‑V Clutch Master Cylinder — Relevance and Service Info

Based on Honda technical literature (Honda CR‑V RE [2007–2011] Service Manual for M/T models, Honda Electronic Parts Catalogue, and 2009 Owner’s Manual specifications), a clutch master cylinder is only fitted to 2009 Honda CR‑V vehicles with a manual transmission. Most Australian and New Zealand 2009 CR‑Vs were sold with a 5‑speed automatic, which does not use a clutch master cylinder because the transmission is fully automatic and has no driver‑operated clutch. Owners should check the vehicle’s transmission type (and VIN) to confirm fitment.

For 2009 CR‑V models with a manual gearbox, the clutch master cylinder is a small but critical hydraulic pump that turns pedal movement into hydraulic pressure, sending fluid to the slave cylinder to disengage the clutch smoothly. It’s what gives the pedal its feel and allows clean gear changes without graunching. Honda’s service information for the RE‑series manual models details a conventional hydraulic layout, and the 2009 Owner’s Manual specifies use of DOT 3 brake fluid in the clutch hydraulic circuit where fitted.

As part of routine servicing, it’s smart to inspect the master cylinder, lines and reservoir for leaks, perishing rubber, or low/dirty fluid. Many techs recommend replacing clutch hydraulic fluid every 2–3 years to keep moisture at bay and pedal action consistent. Use fresh DOT 3 brake fluid (as per Honda specs), avoid contamination, and protect paintwork under the bonnet—brake fluid is harsh on finishes.

Signs the clutch master cylinder may be on the way out include:

• Spongy or sinking clutch pedal
• Difficulty selecting gears, especially first or reverse
• Fluid weeping at the firewall or around the pedal box
• Dark, murky fluid in the reservoir

Replacement is straightforward for a trained tech: match the part to the VIN, bench‑bleed the new master, fit with care to avoid cross‑threading lines, then bleed the system thoroughly. If the vehicle has high kilometres, it’s common practice to assess the slave cylinder and the flexible hose at the same time—replacing them together can save a second bleed later. After bleeding, confirm pedal free‑play and engagement point feel, and road‑test for clean gear shifts. Done right, a fresh master cylinder restores a crisp, predictable pedal and protects the clutch from partial engagement that can accelerate wear.

Popular questions about 2009 Honda CR‑V clutch master cylinders

Does a 2009 Honda CR‑V have a clutch master cylinder?
Only if it’s a manual. Automatic 2009 CR‑Vs don’t have one. Manual RE‑series models use a hydraulic clutch with a master and slave cylinder as outlined in Honda’s service documentation.

What fluid goes in the clutch master cylinder on a 2009 CR‑V?
Use DOT 3 brake fluid, as specified in the 2009 Owner’s Manual. Keep it clean, don’t mix fluid types, and replace fluid periodically to maintain pedal feel.

When should the clutch master cylinder be replaced?
There’s no fixed kilometre interval. Replace if there are symptoms like a sinking pedal, difficulty selecting gears, visible leaks, or contaminated fluid. Many workshops also evaluate the slave cylinder at the same time to avoid duplicate labour and bleeding.
