Parts for your 2008 Mazda Premacy-Cluth slave cylinder

2008 Mazda Premacy clutch slave cylinder (cluth-slave-cylinder)

Based on technical references, the 2008 Mazda Premacy (also known as Mazda5, CR series) with manual transmission uses a hydraulic clutch system with a concentric clutch slave cylinder (CSC) integrated with the release bearing. This is documented in Mazda’s CR Premacy/Mazda5 Workshop Manual under the clutch system section, and is supported by the Mazda electronic parts catalogue listings for the hydraulic release cylinder on 5‑speed/6‑speed manuals, as well as major clutch suppliers’ catalogues (e.g., LuK/Schaeffler and Sachs) which list a CSC for this model. Automatic variants do not use a clutch slave cylinder, so the part is not relevant to autos.

On manual models, the clutch slave cylinder converts pedal effort—via the master cylinder and hydraulic fluid—into movement at the clutch release bearing. Being a concentric unit, it sits around the gearbox input shaft and directly operates the pressure plate fingers. This design gives a lighter, more consistent pedal feel and reduces external linkage wear, though it does mean replacement requires gearbox removal.

There’s no fixed replacement interval for the Premacy’s clutch slave cylinder, it’s a service-on-condition component. Routine servicing should include checking clutch operation and the fluid level/condition in the shared brake-fluid reservoir. Using Mazda‑spec DOT 3 or DOT 4 brake fluid and refreshing it about every 2 years helps keep the hydraulic seals healthy. A soft or sinking pedal, difficulty selecting gears, fluid weep from the bellhousing, or signs of contamination in the reservoir are classic hints the CSC or related hydraulics need attention.

When the gearbox is out for a clutch, it’s smart practice to replace the CSC with the clutch kit (disc and pressure plate) to avoid doubling up on labour later. At the same time, inspect the flywheel surface, pilot bearing, rear main seal, and the clutch master cylinder if the system has been running dirty fluid. Bleeding the Premacy’s hydraulic clutch is straightforward but benefits from a pressure or vacuum bleeder for a clean, consistent pedal. Care should be taken to avoid spilling brake fluid on paintwork, and to follow the workshop-verified bleed sequence.

• Not applicable: 2008 Premacy automatic transmissions

Does the 2008 Mazda Premacy have a cluth-slave-cylinder?

Manual versions do—Mazda fits a concentric slave cylinder inside the bellhousing that doubles as the release bearing. Automatic versions don’t have a clutch or slave cylinder at all, so the part isn’t relevant to autos.

How long does a 2008 Mazda Premacy cluth-slave-cylinder last?

There’s no set lifespan. Many run well past 150,000 km if the fluid is kept fresh and free of moisture. Replacement is recommended when there’s leakage, a spongy pedal, poor disengagement, or during a clutch job to save on future labour.

What fluid should be used and how often should it be changed?

Use quality DOT 3 or DOT 4 brake fluid as per Mazda guidance. Refreshing the fluid about every 2 years helps protect the master cylinder and CSC seals, keeps the pedal feel consistent, and reduces internal corrosion.
