Jeep Wrangler Clutch Slave Cylinder

Spot and Fix Jeep Wrangler Clutch Slave Cylinder Problems

Driving your Jeep Wrangler on the highway can certainly make you feel like a macho man. However, your toughness decreases the moment you step on a spongy and soft clutch pedal. Retain your tough image to match your impressive Jeep by arming yourself with simple solutions to your Jeep Wrangler clutch slave cylinder problems. Watch out for these feelings when driving your Jeep.

Loose and soft

You're driving the highway blissfully listening to hard rock songs when but suddenly you feel your clutch pedal has gone soft or loose on you. This normally indicates that your clutch slave cylinder maybe malfunctioning. The malfunction occurs when the slave cylinder begins to leak and air seeps in. This results in air traps and prevents the clutch slave cylinders from responding no matter how hard you push down on the pedal. Check how secure the seal is. If the seal is a bit loose, use self-amalgamating tape and wind it around the seal. Depending on how well you do it, this temporary fix can buy you more than a year's time.

Tough and hard

When driving an older Jeep Wrangler, sometimes, stepping on the clutch pedal could feel like stomping. Old Jeeps could have dirty and sometimes even rusty aged clutch slave cylinders. This prevents the ancient hydraulic linkage from releasing the clutch pedal. Unfortunately, in this case, there is no other choice but to have the old clutch slave cylinders replaced and the hydraulic linkage cleaned.


One of the scariest parts of driving is when you're in the middle of the road and then something jams. Whether it's the radio volume stuck on full blast or your clutch pedal stuck on second gear. When a clutch fails to release, you cannot shift transmission and would result in an alarming gear grinding sound. Stuck clutch is caused by either a leaking or a bad clutch slave cylinder. If leaking is the problem, then you can either fix the leak or bleed the clutch slave cylinder. You other option is to have it replaced.

Other stuff to remember

The symptoms of a bad clutch slave cylinder are similar to a bad master cylinder, so make sure you're troubleshooting the right part.

  • Reviving Your Jeep Wrangler Clutch Slave Cylinder

    For Jeep Wrangler drivers, driving the rough roads are a walk in the park. The tough jeep is known to take on even the most God-forsaken roads. Wouldn't it be embarrassing then to drive on the highway and then suddenly feel like your jeep suddenly refused to respond to you? That's how it would feel like if your Jeep Wrangler clutch slave cylinder fails you. Your old faithful jeep may not be failing you on the outside but inside, age maybe catching up. The usual problem of a clutch slave cylinder is a leak. The seals compress and deteriorate over the years, which causes the clutch slave cylinder to fail in containing the hydraulic fluid pressure. Here are ways on how you can prevent leaking Jeep Wrangler clutch slave cylinder and extend its service life.

    Visual inspection

    Regularly check the condition of your clutch slave cylinder. This is important especially with old Jeep Wranglers. Aside from the seals deteriorating with age, dust and rust would've settled in there that would definitely affect the clutch slave cylinder's performance. Look for any signs of damage like dents or cracks. More importantly, look for signs of leaks like stains outside or inside the cylinder itself.

    Bleed or flush

    Bleed the clutch slave cylinder every time you open to inspect, replace any part of it or refill it with fluid. Bleeding removes air packets from the clutch slave cylinder and the clutch lines. Removing all the air from the hydraulic system prevent and fix soft clutch pedal issues. In addition, bleeding also improves the clutch slave cylinder's response to the master cylinder. You can bleed your Jeep Wrangler clutch slave cylinder in three ways: manually with a partner, with a vacuum pump or with a hose.


    As most of the vehicle's components, you must keep the clutch slave cylinder clean enough to perform properly. Check if the fluid is pristine or looks cloudy and dirty. Aside from the quantity, the condition of the clutch fluid also affects the clutch slave cylinder's performance. The state of the fluid will also indicate if there is a leak in the system. Replace dirty fluid immediately. For the cylinder itself, remove dirt and rub rust spots with a steel wool.
