The hydraulic heart of the manual transmission: the clutch pump
A clutch pump is an essential part in the transmission system of any vehicle with a manual gearbox that uses a hydraulic system to disengage the engine from the gearbox. In our parts section, we understand that replacing this component should not be a prohibitive expense. That's why we offer a wide selection of used clutch pumps that have been rigorously inspected. Since the pump contains no complex electronic components, its simple mechanical structure ensures that a used part in good condition will offer excellent longevity, provided it is correctly installed and the appropriate fluid is used. Whether your vehicle needs a master or slave pump, here you will find the specific, verified part to restore smoothness and precision to your clutch pedal.
Frequently asked questions
It is the main component of the hydraulic clutch system, and its function is to convert the force applied to the clutch pedal while driving into hydraulic pressure. To put it simply: when you press the pedal, the master cylinder compresses the brake fluid and sends it to the slave cylinder, which is responsible for moving the fork and disengaging the clutch disc from the flywheel.
There are generally three signs that the part is failing or broken:
- The most common symptom is that the pedal sinks to the floor with very little effort, as it no longer builds sufficient internal pressure.
- You will be unable to change gears, especially reverse.
- You may notice a loss of brake fluid from the reservoir with no visible leaks in the braking system.
It depends. As a general rule, if the clutch master cylinder or slave cylinder fails, since it is independent from the clutch kit, it is usually enough to replace just the faulty cylinder. However, if the remaining components are also damaged, you will need to replace the entire kit.
For these reasons:
- It will be cheaper than buying a new part.
- It is a mechanical part with no complex electronics, so it can be replaced with ease.
- All our parts are original, offering better quality than generic brand alternatives.
- We stock parts for all models and prestigious makes.
- We carry used clutch master cylinders for older vehicles as well as newer models.
The cylinder connected to the pedal inside the cabin is called the master cylinder (or primary cylinder). The cylinder that physically moves the mechanism inside the gearbox is called the slave cylinder (or receiver cylinder). Both are part of the hydraulic system and can fail.
No, they are not the same. The clutch slave cylinder receives hydraulic pressure from the master cylinder and converts it into mechanical force to move the fork and disengage the clutch disc. In other words, it is an actuating component, whereas the clutch master cylinder is an active, pressure-generating component.
Yes, because even though it is a mechanical part, the replacement involves two critical steps that require experience:
- Once the new cylinder has been installed, the hydraulic system must be bled to remove all air. If any air remains in the system, the clutch will not work properly.
- You must use the correct brake fluid for your vehicle.
