Clutch Receiver: Role, Performance and Price

The clutch slave cylinder works with the main clutch. They act as a transmission: when you press the clutch pedal, the sender and receiver transmit this force to the clutch kit. This is done via a hydraulic circuit containing the brake fluid.

🔍 How does the clutch slave cylinder work?

Le clutch slave cylinder part as a master of clutch clutch control system. They work inseparably. Their role and joint action is to transfer the clutch kit pressure to the clutch pedal by the driver.

When you press this pedal, you first activate the clutch slave cylinder. It consists of a pusher which is activated by pressing the clutch pedal. He then presses the clutch fork, who can control the clutch thrust bearing and then the rest of the clutch kit.

To do this, the push rod drives the clutch sensor piston. This is a movable part designed to plug the hole through which the brake fluid flows. This will then place the hydraulic circuit of the clutch under pressure.

This is where the clutch slave cylinder comes into play. In fact, it is to him that the force of pressure is transmitted, and it is he who then drives the clutch fork, allows you to start the car and change gears.

However, on some vehicles, the system works differently. Sometimes it is not a hydraulic device, but a clutch cable that connects the pedal to the fork. Hence, there is no clutch slave cylinder and of course no transmitter.

To summarize:

• The clutch sensor and slave cylinder work together;
• Their role is to transfer pressure from the driver's foot to the clutch pedal to the stopper through the hydraulic circuit;
• The clutch slave cylinder consists of a cylinder, piston and rod, just like the transmitter;
• The clutch slave cylinder activates the clutch release bearing by pressing on the fork.

🚗 How do you know if the clutch slave cylinder is out of order?

The clutch slave cylinder does not wear out, but it is part of the hydraulic circuit and can be subject to wear. leaks. In this case, it is recommended to change it at the same time as the clutch master cylinder, the seal of which may also be damaged.

The main symptom of a defective HS clutch is a soft clutch pedal. It then sinks without resistance due to a brake fluid leak. After removing the receiver access sleeve, fluid flow is usually visible on the gasket or inner cup.

👨‍🔧 How to replace the clutch slave cylinder?

The replacement of the driven clutch is preferably accompanied by the simultaneous replacement of the transmitter. In any case, this requires replacing the seals as well as bleeding the driven clutch assembly to remove any air present in the hydraulic circuit.

Material:

• Clutch receiver
• Tools
• Pallet
• Flexible pipe
• Brake fluid

Step 1: Remove the clutch slave cylinder.

Before disassembling the clutch slave cylinder, the vehicle must be jacked up if it is a rear wheel drive vehicle. Drain the brake fluid from the hydraulic circuit by disconnecting the line from the reservoir and allowing the fluid to drain into the drain pan.

Then, disconnect the clutch slave cylinder from the transmission and remove the receiver mounting screws, which can then be removed.

Step 2: Assemble the clutch slave cylinder.

After making sure the new clutch slave cylinder fits your vehicle, place it in the housing and tighten the screws. Connect the driven clutch to the transmission. Finally, reconnect the hydraulic line.

Step 3: bleeding the brake fluid

First fill the clutch reservoir with brake fluid, then bleed it. To do this, connect a flexible hose to the bleed nipple of the clutch slave cylinder and immerse its end in a container with brake fluid.

You will need two people if you do not have a brake bleeder that can be used for the clutch too. Ask your assistant to press and hold the clutch pedal while you open the bleed screw.

Let the brake fluid drain until new fluid comes out without air. The clutch pedal will become firm again. Then you can close the bleed screw and check the brake fluid level.

💶 How much does it cost to replace the clutch slave cylinder?

Sometimes it is possible to repair a faulty clutch slave cylinder, but often it is preferable or necessary to replace it. In this case, it is also recommended to replace the clutch master cylinder, the wear of which is usually parallel and therefore similar. The cost of replacing the clutch slave cylinder is about 150 € for the clutch master.

That's it, you know the function of the clutch slave cylinder! As stated in this article, it is part of the clutch master cylinder hydraulic device. It is thanks to them that the clutch and the engine can be connected through the flywheel, which allows the vehicle to shift gears.
