If you own a 2004 Audi S4, you may eventually need to remove and install the clutch slave cylinder. This component is located on the transmission and is responsible for disengaging the clutch when you press the pedal. Over time, the cylinder can wear out and fail, causing issues with shifting and clutch engagement. In this tutorial, we will walk you through the steps to remove and install the clutch slave cylinder on your Audi S4.

Tools and Materials Needed

Before you begin, you will need the following tools and materials:

Tools:

- Socket set - Wrench set - Pliers - Screwdriver - Brake fluid - Clutch fluid

Materials:

- New clutch slave cylinder - Replacement O-rings - Shop towels

Step-by-Step Guide

Step 1: Drain the Fluids

The first step is to drain the brake and clutch fluid from the system. This will prevent any spills or leaks when you remove the clutch slave cylinder. Locate the drain plugs on the clutch master cylinder and the brake fluid reservoir and remove them.

Step 2: Remove the Old Cylinder

Next, locate the clutch slave cylinder on the transmission. Use a socket set to remove the mounting bolts and slide the cylinder off the transmission. Be careful not to damage the hydraulic lines or the O-rings when removing the cylinder.

Step 3: Replace the O-Rings

Inspect the O-rings on the hydraulic lines and replace them if necessary. Use pliers to carefully remove the old O-rings and slide new ones into place.

Step 4: Install the New Cylinder

Slide the new clutch slave cylinder onto the transmission and secure it with the mounting bolts. Make sure the hydraulic lines are properly connected and the O-rings are seated correctly.

Step 5: Refill the Fluids

Refill the brake and clutch fluid reservoirs with fresh fluid. Bleed the clutch system to remove any air bubbles and ensure proper operation.

Step 6: Test the Clutch

Start the engine and test the clutch pedal for proper engagement and disengagement. If the clutch feels spongy or does not engage properly, you may need to bleed the system again.
