Parts for your 1999 Toyota Hiace-Cluth slave cylinder

1999 Toyota Hiace clutch slave cylinder

For the 1999 Toyota Hiace (H100 series) with a manual gearbox, a clutch slave cylinder is fitted. This is confirmed by Toyota’s Electronic Parts Catalogue (which lists a “clutch release cylinder” for 1999 Hiace manual variants) and mainstream workshop manuals for the H100 that describe a hydraulic clutch system with a master and slave cylinder, along with standard bleeding procedures. Independent technical data providers and parts catalogues also list direct-fit slave cylinders for 1999 Hiace models, reinforcing that the cluth-slave-cylinder is relevant to this vehicle.

On this Hiace, the clutch slave cylinder takes hydraulic pressure from the clutch master and turns it into mechanical push on the clutch fork. That movement separates the pressure plate from the friction disc so gears can be selected smoothly. When the slave starts to wear, the van can get hard to shift, the pedal can feel soft or sink, and there may be fluid weeping from the rubber boot or down the bellhousing.

As part of sensible servicing for a 1999 Hiace, it pays to keep the hydraulic side in good nick. Fresh fluid helps prevent internal corrosion and sticky seals, and timely replacement avoids roadside dramas. Toyota commonly specifies DOT 3 brake fluid for the clutch circuit, though DOT 4 is also widely used—check the cap or service data and don’t mix incompatible fluids.

• Top maintenance tips
  • Inspect the slave cylinder and line for leaks or perishing each service.
  • Flush the clutch fluid about every 2 years or 40,000 km, keeping the reservoir topped while bleeding.
  • Use a flare-nut spanner on the line fitting and keep brake fluid off paintwork.

Replacing a tired cluth-slave-cylinder on a Hiace is straightforward for a competent home mechanic, but a workshop will knock it over quickly too. Expect to:

1. Unbolt the slave from the bellhousing and crack the hydraulic line with a proper flare-nut spanner.
2. Fit the new unit, transferring any pushrod/boot if required.
3. Bleed at the slave’s bleed screw until clean, bubble-free fluid runs, keep the reservoir topped the whole time.

Afterwards, pedal take-up should be consistent, engagement smooth, and there should be no dampness around the slave. If the pedal still feels spongy, re-bleed or check for air at the master and lines. Given the age of a 1999 Hiace, it’s common to replace the master and slave together if one has failed, restoring the whole hydraulic system in one go.

Popular questions about the 1999 Toyota Hiace cluth-slave-cylinder

Does a 1999 Toyota Hiace have a clutch slave cylinder?

Yes. The 1999 Hiace with a manual transmission uses a hydraulic clutch with a master and slave cylinder. Toyota’s parts catalogue calls it the “clutch release cylinder”, and workshop procedures cover bleeding and replacement of this component.

What are the signs the slave cylinder is failing on a 1999 Hiace?

Common clues include a soft or sinking clutch pedal, difficulty selecting gears from a stop, clutch fluid loss, and dampness or weeping under the slave cylinder’s rubber boot. Left alone, it can lose hydraulic pressure and leave the Hiace stuck in gear.

How often should the clutch fluid be changed, and what fluid should be used?

A practical interval is every 2 years or around 40,000 km. Use clean brake fluid meeting DOT 3 (or DOT 4 if specified/approved). Always check the reservoir cap or the service data for the exact recommendation and avoid contaminating the system.
