The transmission system has a lot of components that work together to allow an automobile to run; however, this equally means that there are a lot of components that can make the system fail and prevent your car from running smoothly. Learn how much does it cost to replace a master cylinder.

Your transmission system has three main parts: the engine, the transmission, and the clutch. The last on this list is usually called more commonly “the slave cylinder”. This component of your transmission helps you to disengage the gears inside the manual transmission such as the first gear or reverse gear.

All are very important and one of those parts is the master cylinder. Other than keeping the driving force moving forward, another function of this part is to apply pressure on other components so there would be a smooth transfer of power from the engine to the wheels.

What is The Function of a Clutch Master Cylinder?

Other than the clutch pedal, a master cylinder is also used by the braking system and serves as a pump with the same concept for fluids such as brake fluid. It has two chambers separated by a disc or plunger. The output chamber pushes brake fluid into two auxiliary piston cylinders connected to each wheel assembly while the input chamber pulls in fluid from both primary and auxiliary side ports. This allows it to compress brake fluid and apply pressure on other components such as brake pads and pistons when drivers step on their brake pedals. 

In a clutch system, a master cylinder provides pressure on the fluid inside a single-piston cylinder. This helps disengage the gears from each other to move your car forward and backward.

They both play a vital role in your vehicle’s performance. If a master cylinder fails, it can cause you not to be able to stop the car or disengage gears which will only result in accidents and other serious damages so this is why owners must regularly maintain their car’s components such as by replacing them on time if faulty. 

Average Master Cylinder Replacement Cost

When discussing the cost of replacing a master cylinder, the most common problem with this is that there can be various factors that will determine how much it will cost to replace it. In general, owners must spend an average of around $400 to $500 in order for them to get a new one and have their clutch system fixed

However, you may need to pay more or less depending on several factors such as the type of car you have, the brand of the replacement part, and labor costs. 

For the part itself, the average cost of a master cylinder costs around $255 per unit. However, it is important to note that most make and models have different prices for this part. For instance, some brands only charge an average of $215 while others can go up to as much as $420. 

On top of all these factors, another factor that you should keep in mind is that labor costs are usually around the same price range or even more expensive depending on where you are having your car serviced. On average, they charge between $130 to as high as $200 per hour for labor costs with an estimated average labor time of between 1 to 2 hours.

This can bring your total average cost to as much as $800 up to as low as $300.
