Parts for your 2007 Toyota Ist-Cluth slave cylinder

2007 Toyota ist cluth-slave-cylinder: what it is, where it fits, and how to keep it sweet

Based on Toyota’s service literature for the NCP110/NSP110 platform (ist/xD) and the Toyota Electronic Parts Catalogue, the 2007 Toyota ist fitted with a 5-speed manual transmission uses a hydraulic clutch system with a clutch master and a cluth-slave-cylinder mounted on the gearbox bellhousing. Automatic or CVT versions don’t use a cluth-slave-cylinder because they don’t have a manual clutch to actuate.

On a manual 2007 Toyota ist, the cluth-slave-cylinder is the hard-working bit that converts pedal pressure (via hydraulic fluid from the clutch master cylinder) into mechanical movement at the clutch fork. That movement disengages the clutch so gears can be shifted smoothly. It’s a simple, robust setup that shares brake-style hydraulic fluid and often the same reservoir, which is why fluid condition matters heaps for both braking and clutch feel.

As part of regular servicing, it pays to keep an eye on the cluth-slave-cylinder and its fluid. Brake/clutch hydraulic fluid absorbs moisture over time, which can corrode internal seals and bores. A periodic flush (every 2 years or around 40,000 km is a sensible Aussie/Kiwi rule of thumb) helps stave off spongy pedals and premature seal wear. Always use the correct spec (Toyota typically calls for DOT 3, DOT 4 is acceptable in many climates) and take care not to spill it on paint.

• Check for leaks at the slave’s dust boot and line fittings—dampness or drips mean it’s time for attention.
• Watch for a low bite point, a soft or sinking pedal, or difficulty selecting gears—classic signs the slave (or master) is tired or there’s air in the system.
• Bleed the system properly after any work, a small bubble can make the pedal feel ordinary.

If the cluth-slave-cylinder is leaking or sticking, replacement is typically straightforward: crack the line, remove the mounting bolts, swap the unit, and bleed. Many techs recommend replacing the clutch master at the same time, especially on higher-kilometre cars—if one cylinder’s worn, the other’s usually not far behind. Inspect the rubber hose for cracking and the hard line for corrosion while you’re there. With a fresh cluth-slave-cylinder, good fluid, and a tidy bleed, the 2007-toyota-ist clutch action should feel light, consistent, and drama-free.

Popular questions about the 2007-toyota-ist cluth-slave-cylinder

Does every 2007 Toyota ist have a cluth-slave-cylinder?
No. Only manual-transmission models use a cluth-slave-cylinder. Automatic or CVT versions don’t have one because there’s no manual clutch to hydraulically actuate.

What fluid should be used and how often should it be changed?
Toyota generally specifies DOT 3 brake fluid for the clutch hydraulics (DOT 4 is acceptable in many cases). A 2-year or roughly 40,000 km interval works well in Australian and New Zealand conditions, or sooner if the fluid looks dark or contaminated.

What are common symptoms of a failing cluth-slave-cylinder on a 2007-toyota-ist?
Look for a soft or sinking pedal, clutch engagement right off the floor, difficulty selecting gears, or visible leakage at the slave’s dust boot. Air in the system can mimic some of these, so a proper bleed is worth trying before condemning the part.
