5 Causes of a Stiff Clutch Pedal

There are many people in the world who still drive vehicles with a manual transmission although that’s slowly changing. These vehicles have a clutch pedal on the floor to the left of the brake pedal.

The clutch is what links the wheels to the engine. All the rotational energy created by the engine gets transferred to the wheels through the clutch.

If you ever have problems pressing down on the clutch, then you will have problems transferring power to your wheels. This will ultimately result in the inability to drive safely on the road.

Top 5 Reasons for a Hard Clutch Pedal

When you step on the clutch pedal with your foot, there should not be too much resistance. A normal clutch pedal depression will feel nice and smooth.

It won’t be too hard or too soft. It should feel just as easy to press as the other two pedals on the floor.

However, if you feel that the clutch pedal is hard to press, then there could definitely be something wrong within the system. Below are five of the most common causes of a clutch pedal being hard to press down.

1) Bad Drive Shaft

The drive shaft is the component of the transmission system that is responsible for transferring the rotational energy from the engine to the wheels. It is linked to the clutch pedal and cable components.

If your drive shaft or any of its components were to get too worn out, then it may cause problems when it comes to pressing down on the brake pedal. It will also impair the performance of your entire transmission too.

This would definitely be a reason to go to the mechanic and get these problems fixed.

2) Bad Pivot Ball

The clutch pivot ball is designed to make the operation of the clutch feel as smooth as possible. It is what gives the clutch pedal that smooth feel when you press down on it with your foot.

But if the clutch pivot ball were to get worn out or damaged, the smoothness of the feel will start to fade. Instead, you will be left with a stiffer clutch pedal that will require more force to press down.

3) Bad Clutch Cable

The clutch cable is what connects the clutch pedal and clutch linkage of the transmission together. When you press down on the clutch pedal, it causes the cable to pull on the linkage so that the clutch becomes disengaged.

Once the clutch is disengaged, you can shift the gears of the transmission safely. But if the clutch cable is stretched too much or broken, then you will have to press down harder on the clutch pedal to disengage the clutch.

4) Bad Linkage

The clutch linkage is comprised of the many hydraulic or mechanical components which allow the clutch to function properly. Aside from the clutch pedal, the linkages consist of various arms and rods.

When you press down on the clutch pedal, the linkage multiples this force so that it can impact the pressure plate. This creates the necessary force to disengage the clutch on demand.

5) Pedal Blocked

If you have small items on the floor of your vehicle, it is possible that one of these small items might be caught underneath the clutch pedal. If this happens, you won’t be able to press down the pedal completely.

You might not think to look underneath the pedal because it probably won’t occur to you that this is the reason it is sticking. If you ever need to press down hard on the clutch pedal, make sure there is nothing underneath it.

Otherwise, it could damage the pedal or prevent you from disengaging the clutch. Even worse, the object can get stuck under your brake pedal with much dire consequences.

  1. Hi I have just purchased a 2017 ford focus st3 when I drive I find the clutch a bit harder than normal to operate. Should I have this checked out by the local ford dealer

    • It depends what you are comparing it to. Since you have the high performance version of a normal Focus, you likely have a stronger clutch plate to handle the extra horsepower. This often means your clutch pedal will take more effort to push down. But if you’re concerned, I’m sure a Ford sales rep would be able to tell you if it’s normal or not.

    • If it’s got more than 20,000 miles on it I would recommend changing the manual transmission fluid (DCTF). It uses dual clutch transmission fluid and the only fluids I’ve found so far that meet Ford’s specs are Motorcraft DCTF and Motul DCTF. There’s a few good YouTube videos online that cover how to do it. Medium difficulty.

  2. I’ve got a Suzuki GV -2006 – 2.0TD 5 Fwd manual .
    I’ve replaced release bearing, clutch plate, pressure plate, pilot bearing lube pivot ball. Release bearing inner surface was also lubed. All service parts are OEM.(Clutch Kit manufactured by Valeo for Suzuki).
    Clutch slave was also replaced and brake fluid flows unrestricted when system was bleeded. Clutch pedal was hard before i replaced parts and still the pedal is hard.
    Firstly, what can i further check? And secondly, is there any device / system that i can add on to get a softer clutch pedal?

  3. 94 Jeep Wrangler. For all practical purposes my clutch works fine. But on occasion, the clutch seems to lock up and I can not press down on it at all…like a rock when I push on it. It will then loosen up on its own and the clutch works perfectly again. This just started happening and does it periodically. Any ideas here?

    • Is there fluid leaking underneath? If so, either a bad master cylinder, bad slave cylinder, or hydraulic line blew off. If no leak, I’d guess the throwout bearing. Many Jeeps also have an issue with a failed return spring in the clutch master cylinder.

  4. Hi,
    I just bought an 2012 accord coupe. After driving in heavy traffic a few times I noticed I really have to put in a lot of effort to push the clutch down. Took it to my mechanic and he said it seems OK to him and to check further he would have to take out the whole transmission.
    I plan on having this car for a long time and my knee hurts just thinking about it.
    Any advice?

    • Are you sure it’s the stock clutch or did the previous owner upgrade to a heavier duty clutch do to mods? Either way, unless your mechanic actually checked the cable and linkage, you might want to have another mechanic check it out.

  5. Hi,
    After i drive my Hyundai i20 for one hour, all of a sudden clutch starts becoming stiff and eventually, it will become so stiff that i cannot change the gear at all. If i leave the vehicle in that state for half an hour to one hour, again the clutch becomes normal and i can drive as if nothing has happened. Because of this problem, unable to use the car for long journeys. what may be the problem. Already got the gear plates replaced from Hyundai service centre. When i go to service station, unable to show the problem, and when the problem comes, unable to show to service person. horrible situation.
    Thanks in Advance.

    • I would start by inspecting the clutch pedal assembly, clutch master cylinder, and slave cylinder for damage. See if there’s anything wrong with those parts that could be mechanically limiting the clutch pedal travel.

  6. I recently replaced both the clutch and the pressure plate on my land cruiser vx but the clutch padel is too hard to press

  7. My Mazda BT 50 ..4WD from 2011 the clutch pedal has always been relatively hard to push down ( I didn’t realise as had old Landriver Defender prior). It’s leaking some oil and mechanic has been saying for past 18 months that the clutch is on way out. Have driven 100000km in past 2 years..
    Do I have to do new clutch ..and change from dual to single flywheel..at cost of $2000 😬

  8. I changed the master cylinder on my 98 Ford Ranger and bled the system. Now when I engage my clutch pedal, the brake pedal goes down enough to noticeably slow my truck. any suggestions as to what might cause this?

    Reply
    • On my cars the clutch and brake hydraulic systems are completely decoupled where a failure in one cannot affect the other. I don’t think Rangers were designed this way. I would bleed the brakes and the clutch, then see if the issue persists.

      As a sanity check, look up the proper bleeding procedure for your truck in case it calls for anything unconventional.
