The master cylinder is typically located directly in front of the clutch pedal. This one is mounted to the firewall.

Parts made by automakers are considered original equipment manufacturer (OEM). Aftermarket parts from suppliers that work directly with automakers are original equipment (OE). We recommend buying an OEM or OE clutch master cylinder - opens in new window or tab..

For many DIY jobs, parts and accessories from aftermarket suppliers who are not the original producer—and did not work with them—can be easily interchanged to save money. For example, there’s no need to buy Honda-branded coolant. But that’s not the case with a clutch master cylinder.

Clutch master cylinders are not universal. Enter your year, make, model, engine, and trim into the eBay Parts Finder - opens in new window or tab.. This lets you search for clutch master cylinders designed to fit your vehicle. All the bolts line up to the same places, and everything fits together. Keep an eye open for OEM or genuine OE parts. These are high-quality parts on par with what came on your vehicle when it rolled off the assembly line.

Clutch master cylinders are similar to brake master cylinders. Some have a reservoir integrated into one unit and others have a remote reservoir. One kind is not an upgrade from the other. Buy what fits your vehicle.

How Much Does a Clutch Master Cylinder Cost?

Most clutch master cylinders cost between $25 and $75. This price depends on the type of vehicle you drive. Branded OEM parts are more expensive. As part of the replacement, you’ll also need to add clutch fluid - opens in new window or tab., which adds a minor expense. Clutch and brake fluid are the same. Doing this job yourself will likely save between $100 and $300 on labor charges if you were to have a shop do the work.

Buying a Used Clutch Master Cylinder (or Rebuilding One)

Do you have an older vehicle with a rare clutch master cylinder? A used part may be your only way to find a high-quality OEM part. That’s fine if you buy from a reputable seller that has a good return policy.

It probably makes sense to replace rather than rebuild your brake master cylinder. However, rebuild kits are relatively inexpensive. They come with all the new seals, O-rings, springs, and clips you need, and usually a new piston.

The problem is when an old clutch master cylinder has suffered years of abuse, and old fluid may be pitted on the inside. New O-rings and seals can’t fix a pitted master cylinder. In some cases, you might rebuild your clutch master cylinder only to discover that it still leaks. So, you need to pull it out after the time-consuming process of rebuilding, re-installing, and re-bleeding the clutch.

When replacing the master cylinder, you will need to fill the reservoir with new clutch fluid (which is the same as brake fluid). Most clutch masters use DOT 3 - opens in new window or tab. or DOT 4 - opens in new window or tab. brake fluid, which are compatible with each other.

The clutch master cylinder has a corresponding clutch slave cylinder. Buy a new clutch slave cylinder - opens in new window or tab. with your clutch master cylinder. Replace them together. It doesn’t add a lot of cost to your order, and it saves time. If you replace both together, you only have to bleed the system once.

With some vehicles, you can purchase a kit - opens in new window or tab. that comes with the required hydraulic lines and fluid.

During a master cylinder replacement, inspect the entire system. Check for leaks around the slave cylinder and along the lines. Finally, give the clutch pedal a quick check to make sure it’s properly adjusted.

These tools are necessary when installing a new clutch master cylinder:

Wrenches and socket set to remove the bolts on the clutch master cylinder
A line wrench to remove hydraulic lines
Snap-ring pliers if the master cylinder has internal snap rings holding it in place
A bleeder wrench to remove air bubbles
Plastic or rubber tubing for bleeding
Fluid catch container
Brake cleaner for removing dirt and grime
Funnel for adding new fluid

Wearing rubber gloves and safety glasses will ensure safety. You don’t want any brake fluid on your hands and you definitely don’t want any in your eyes.

It’s also helpful to have shop towels or rags handy for cleaning up any messes. Brake/clutch fluid can remove paint. Keep any spills contained. Don’t let brake-fluid-contaminated gloves leave fingerprints on painted metal.
