Clutch Master Cylinder

The Exedy MC238-K Clutch Master Cylinder serves as a direct OEM replacement, designed to restore proper clutch hydraulic function. If your clutch pedal feels spongy, sinks to the floor, or exhibits inconsistent engagement, this master cylinder can resolve those issues by ensuring proper pressure buildup. Its internal seals are built to OEM specifications to prevent internal fluid leaks that degrade pedal feel and engagement. Engineered with an OEM-spec bore size and stroke, this master cylinder ensures your clutch pedal height and engagement point will feel identical to a new factory unit. It offers a straightforward, direct-fit installation, bolting directly to the firewall, threading into the hard line, and connecting to the clutch pedal without requiring modifications. This component is designed to work seamlessly with both stock and performance aftermarket clutches, including Stage 1, 2, and 3 units, handling their increased pressure demands without issue. Installation requires bleeding the clutch hydraulics with fresh DOT 3 or DOT 4 brake fluid; do not reuse old fluid. It is also recommended to inspect and potentially replace the slave cylinder concurrently if it is old or showing signs of leakage, as an air-filled system or a faulty slave cylinder can mimic master cylinder issues. This part is exclusively for manual transmission vehicles. This clutch master cylinder fits the following FWD applications: 1994-2001 Acura Integra (including GS, RS, LS, Special Edition, GS-R, and Type R trims), and 1992-2000 Honda Civic.
