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. 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.

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. 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. 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 Clutch fluid will wear out and break down, so if you have a vehicle with over 100,000 or 200,000 miles and notice that the clutch fluid is a little dark, this is entirely normal. Go ahead and flush the fluid and see if that fixes your problem. Most cars have a coolant reservoir that have minimum and maximum levels marked on the side, this means that you can simply have a look to see if it is between the ideal levels. How to top up coolant

Fluid Reservoirs

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. In many car models, the clutch master cylinder uses the brake fluid, so they use a shared reservoir. Therefore, if you can’t find the clutch fluid reservoir, it is most likely using the brake fluid. 2. Soft or Spongy Clutch Pedal 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. If the reservoir is empty, you’ll have to bleed the brakes. Since most modern cars have some sort of advanced braking system, then you will likely have to take it to a professional to get this done properly.

As alluded to above, your brake system and hydraulic clutch system share many similar parts. So if you’re comfortable working around a brake system, this should all be pretty easy for you. There are essentially two types of hydraulic clutch actuator designs that you’ll likely come across. First, there’s the pushrod style, which is basically just a piston that moves a linkage attached to a clutch fork. Pushing the clutch pedal actuates the pushrod, moving the cylinder and engaging the clutch fork (kind of like a traditional all-mechanical clutch). 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 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. 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.So, if you have a soft or spongy clutch pedal, that means there’s a leak somewhere in the system. One of the most likely culprits is the clutch master cylinder. 3. Your Clutch Engages at a Different Point Depending on the make of your car, the power steering fluid reservoir may have level markings similarly to the coolant, where you can visually to see if it is in the optimal level. 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. 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

We’ll speak in general terms because front-wheel transaxle vehicles have a slight different look than a rear-wheel drive setup. And based on the type of clutch actuator you have (pushrod or bearing, explained above), your bleeding job will be slightly different too. The most common symptom of a bad clutch master cylinder is a low clutch or brake fluid level due to a leak. It can also cause a soft or spongy clutch pedal or other issues with the clutch pedal. Sometimes, it can cause the clutch pedal to stay on the floor. Don’t rush this, it’s better to put in oil little and often, as over-filling can cause leaks. Coolant/Antifreeze Getting a low level float switch in that tiny reservoir would need a bespoke solution, I very much doubt the standard Ford type brake master cylinder float switch you've linked would fit.

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. Your clutch fluid is like your brake fluid in that if it feels spongy or soft, you have water or air in the system. Moisture in a hydraulic system is a killer, and with clutch fluid, there’s no reason that it should ever be there. Make sure you have the correct oil for your car, then pour some in –you can always use a funnel for this if you think you might spill. Lightly smear a small amount of high melting point grease to the input shaft, and then mount the new clutch plate on the input shaft which will ensure the clutch plate is correct in fitment. Evenly distribute the grease, remove the clutch plate and wipe off any excess grease. Using a clutch alignment tool, mount the new clutch on the flywheel, making sure the clutch plate is located correctly with ‘Gearbox Side’ or ‘Getriebe Seite’ facing the gearbox and tighten in an even and sequential manner (see below).
