Clutch master: functions, change and price

The clutch master cylinder is part of the clutch control system that allows the vehicle to change gears. It works with the clutch slave cylinder and transfers the force acting on the clutch pedal to the stopper. The clutch master cylinder is rarely changed except in the case of a leak.

🔍 What is a master clutch?

Theclutch master is part of the mechanism that controls the clutch, which allows the vehicle to change gears. When you press clutch pedal, the force you apply with your foot is transferred to the clutch release bearing hydraulic circuit containing brake fluid.

Making this transmission is the role of a clutch master. It consists of a cylinder and a pushrod, which is actuated by the clutch pedal when pressed. This rod will allow you to grow on clutch fork, which in turn activates Clutch thrust bearing.

Indeed, the piston of the clutch master cylinder rotates the pusher. Movable, this piston will then close the filler hole brake fluid, allowing you to build up pressure in the hydraulic circuit. This force is transmitted to the clutch slave cylinder, which drives the fork.

Here's how to connect and disconnect flywheel clutch that allows you to start and change gears.

However, there are different clutch control systems. Unlike the hydraulic system, the device can also be operated with a cable that connects the clutch pedal to the fork for actuation. In this case, there is neither a clutch sensor nor a clutch slave cylinder.

The hydraulic device is more expensive, but its advantage is that it cannot jam and has no cables to break. The pressure in the chain is always constant, and the force is on the larger fork.

🚗 What are the symptoms of the HS Clutch Master?

The main clutch assembly is susceptible to leaks primarily because it is part of the hydraulic circuit in which the brake fluid circulates. You will recognize the HS Clutch Master by the following features:

• Liquid oozing out at the transmitter input;
• Depressing the clutch pedal too easy;
• Gear shifting problems ;
• Clutch pedal too hard, Against.

To get the clutch master cylinder repaired, you may need to replace it completely. But sometimes only the gaskets can be replaced. There are clutch master repair kits on sale.

🔧 How to change the clutch master?

If it leaks, the clutch master cylinder must be replaced. However, the operation differs from vehicle to vehicle. We recommend that you replace the receiver at the same time as the clutch sender and take the opportunity to check the rest of the clutch kit.

• Tools
• Clutch Master

Step 1: disassemble the clutch master

You need to start by defining the clutch master cylinder. To access it, you will have to remove the plastic cover under the steering wheel to reach the clutch. You must first change the brake fluid before disconnecting the connection between the sensor and the clutch pedal.

Then remove its pipes and finally the clutch master itself by unscrewing its mounting screws.

Step 2: assemble a new master clutch

Install the clutch master cylinder in its place and replace the set screws. Assemble the pipes and then connect the transmitter to the pedal. If you are not changing the clutch slave cylinder with the sensor, bleed and equalize the brake fluid.

Step 3: Replace the clutch slave cylinder

It is recommended to replace the clutch slave cylinder at the same time as the transmitter. Remove its mounting screws and tube to disassemble it. Install the new receiver and reassemble the pipe and then the screws. Finally, bleed the hydraulic circuit and check the fluid level.

💳 How much does a clutch master cost?

The cost of replacing the clutch master cylinder is approximate 150 €as well as the clutch slave cylinder. It is desirable to change both at the same time. You can buy a clutch master yourself for about 30 euros, depending on your car model.

Now you know everything about the transmitterclutch ! As you understand, its work is inseparable from the clutch slave cylinder. Together they make it possible to manage cork which, in turn, will press the clutch mechanism until you can change gears.
