Parts for your 1999 Nissan Navara-Clutch master cylinder

1999 Nissan Navara Clutch Master Cylinder

According to the Nissan D22 Navara Factory Service Manual (CL – Clutch section, 1997–2004), the Nissan FAST electronic parts catalogue for D22 models, and major aftermarket catalogues (e.g., Exedy/ATE listings for 1997–2001 Navara), the 1999 Nissan Navara with manual transmission uses a hydraulic clutch system with a clutch master cylinder feeding a slave cylinder. So, yes—this ute is fitted with a clutch master cylinder from factory.

The clutch master cylinder’s job is straightforward: when the driver presses the pedal, the master converts that movement into hydraulic pressure, sending brake fluid (DOT 3 as specified) down to the slave cylinder on the gearbox bellhousing. That pressure moves the release fork and pressure plate so gears can be selected smoothly. A healthy master cylinder keeps pedal feel consistent, take-up point predictable, and shifting drama-free—whether it’s around town or hauling on rural roads.

As part of servicing, the master cylinder and its fluid deserve attention. Brake fluid is hygroscopic, so moisture ingress over time can cause internal corrosion and spongy pedal feel. Many owners choose to flush the clutch hydraulic circuit when they do the brake fluid—typically every 2 years. Always use fresh, sealed DOT 3 fluid (DOT 4 can be acceptable in some markets, but follow the service manual and cap marking). Keep fluid off paint, it can damage the finish quickly.

• Watch for tell-tales of a tired master: a sinking pedal, inconsistent bite point, dark or gritty fluid, dampness around the firewall under the reservoir, or difficulty engaging gears when hot.
• Bleeding is done at the slave cylinder nipple: keep the reservoir topped up, crack the bleeder, press and hold the pedal, then close before releasing. Repeat until clean, bubble-free fluid appears.
• If replacing the master: disconnect the pushrod clevis at the pedal, remove the two firewall nuts, swap the unit, bench-prime if possible, refit lines, then bleed. Adjust pedal height and free play to factory spec from the service manual.

Quality replacements are widely available and usually straightforward to fit. Allow for new copper washers if the line uses banjo fittings, inspect the rubber hose for cracks, and consider doing the slave cylinder at the same time if it’s old—the pair tend to age together.

Popular questions about 1999 Nissan Navara clutch master cylinder

Does a 1999 Navara have a clutch master cylinder?
Yes. Technical references including the Nissan D22 Factory Service Manual (CL section) and the Nissan FAST EPC list a hydraulic clutch system with a master and slave cylinder for 1999 Navara manual models.

What fluid should be used in the Navara’s clutch master cylinder?
The service documentation specifies DOT 3 brake fluid for the clutch hydraulic system. Owners often service it alongside brake fluid changes. If considering DOT 4, confirm compatibility with the cap label and the service manual for the specific variant.

What are common symptoms of a failing clutch master cylinder, and what does replacement involve?
Symptoms include a soft or sinking pedal, difficulty selecting gears, fluid weeping at the firewall, or a take-up point that wanders. Replacement typically involves disconnecting the pedal clevis, removing the firewall fasteners, swapping the unit, then bleeding the system and setting pedal free play to spec. Labour time is commonly around 1 hour, varying with condition and access.
