Once the fluid coming out of the bleeder valve starts looking clean (and bubble-free) in the vacuum hose, remove the vacuum tool. Now, if gravity is allowing fluid to drip out, you may be able to simply tighten the bleeder valve shut and be good to go. Master cylinders are available in a choice of bore sizes which can alter the amount of braking force and fluid displacement which are applied when the brake pedal is pressed. This is not only important for providing sufficient pressure through the braking system to obtain the optimum braking performance from the installed hardware, but can also have an impact on the feel of the brake pedal for the driver.

The good news is, the process of changing your hydraulic clutch fluid is dang-near identical to bleeding brakes. Better still, you don’t have to deal with multiple lines going to each caliper/wheel cylinder, so the process is probably going to be a whole lot easier than a brake job. It’s worth nothing that in some cars, in particular those from the VW Group (Volkswagen, Seat, Skoda, Audi), need a specific type of coolant/antifreeze. Your vehicle handbook will state what type you’ll need and can often be a different colour (in the case of VAG cars, it is dyed purple). At the CarShop Service Centre we can identify any fluid visually and by the Autodata system, and can provide the correct coolant too! With the vehicle positioned on the ramp and before raising, starting under the bonnet, disconnect the battery, remove the engine cover, disconnect the air mass meter and remove the air filter housing and ducting. Then disconnect the turbo boost pressure sensor multiplug and remove the upper charge air hose and, with these removed we now have better access to the gearbox area.

If your clutch fluid has dropped dramatically, then it’s likely that your clutch is going to engage at a different point too. The usual result is that you’ll have to fully depress the clutch pedal to disengage the clutch, which is typically far different than your usual engagement point. Clutch fluid level should not fall as the clutch itself wears. It might actually rise. If the level is dropping you need to find the leak. You’ll also need to replace the clutch fluid, which usually consists of brake fluid. This is a small cost, but you’ll need to factor it in.

For normal driving conditions, use a 50/50 mix of water and antifreeze, you can get this from the local supermarket so you won’t need to go out of your way. If you don’t have antifreeze and are desperate to top up, you can fill with tap water in the meantime, but ensure that the correct antifreeze concentration is added ASAP. It’s worth mentioning that you can’t leave the reservoir open too long, and the same goes for the container with the new fluid. This is because the fluid will absorb moisture from the air and can ultimately cause corrosion in the brake system. How to top up brake fluid In most cars, you can’t actually see the screen wash reservoir level, only the cap for it. You will know it will need topping up if the nozzles don’t spray anything or if your car tells you. How to top up screen washYour clutch master cylinder is typically located in front of the clutch pedal but on the other side of the firewall in the engine bay. You can often find it close to the brake master cylinder. The clutch fluid reservoir will usually have a minimum and maximum level marker, you can easily see whether the fluid is between these two points – if it is then great! You don’t need to do anything else. How to top up clutch fluid While opinions differ, you’ll probably want to change your hydraulic fluid every time your change your brake fluid. As mentioned above, the two systems often share fluids, which makes it easier to shop for. And, it tends to be a messy, drippy job, so it’s probably best to get it done all at once. Remove both front wheels, front hub nuts and the N/S/F wheel arch liner and remove the inner driveshaft gaiter retaining bolts (see below). Don’t worry, you don’t need any fancy tools or expertise to do this, all you need is a few paper towels and 5 spare minutes. Before you begin

No, we’re not yanking your chain; clutch fluid is a real thing. And if you’re looking in the clutch fluid reservoir, the fluid should always be at the same height. Otherwise, you have a problem somewhere in the system, and the most likely culprit is a leaking clutch master cylinder. Not only can it change the engagement point, but it can also do it over a short period of time. That means you might not have any problems on your way home from work, but when you hop in the car the next morning, you might stall it out a few times while you try to figure out what’s going on. If the clutch fluid is below the bottom marker, then you will need to top up. Brake fluid can also be used as clutch fluid (most containers will read “brake & clutch fluid”). All you need to do is remove the cap and fill until the fluid sits between the two makers. Windscreen wash If you want to use concentrated screen wash, then make sure you read the label. This will tell you how much to use during the year. In winter, you’re likely to need more concentrate to prevent freezing, as you should never use antifreeze here. Then you can mix the screen wash with tap water to dilute it. Typically, the clutch master cylinder directly connects to the clutch pedal via a pushrod, so if you draw a straight line from your clutch pedal into your engine bay, you’ll usually find the clutch master cylinder. Clutch Master Cylinder Replacement Cost

the first thing to do is bleed the clutch hydraulics and ensure that you replenish the all fluid in the system and get any trapped air out Don’t rush this, it’s better to put in oil little and often, as over-filling can cause leaks. Coolant/Antifreeze The other actuator design is becoming increasingly common in modern vehicles. The clutch is actually housed in a bearing that fits around the transmission’s input shaft. When the clutch pedal is pressed, it actuates a hydraulic throwout bearing that pushes against the clutch diaphragm to disengage your clutch. Next, examine the quality/color of the fluid itself. Normally, the fluid is clear with perhaps a yellowish tint. But if you haven’t changed it in a while, there’s a good chance it’ll be cloudy, dirty, and dark. If that’s the case, you should purge/bleed the system to replace the old fluid.

For motorsport applications, master cylinders can be supplied with either an integral fluid reservoir that is encased within the unit, or as a remote reservoir style which allows the brake fluid reservoir to be mounted elsewhere if the application has restricted space or there is the need for mounting a larger reservoir.

Fluid Reservoirs

They only hold an egg cup full of fluid at best and even less in a Chimaera because TVR didn't fit the cylinder in the horizontal plane as it was designed to be.
