How to diagnose the problem with the clutch that has suddenly stopped working.

A harder clutch pedal in your Toyota Fortuner 3.0L D4D 2007 could be indicative of several potential issues. It's important to have a qualified mechanic inspect and diagnose the specific cause, but I can suggest some common reasons for a harder clutch pedal:

• Clutch Wear:
• The clutch may be nearing the end of its life and may require replacement. Over time, the clutch disc and pressure plate can wear, leading to a harder pedal feel.
• Clutch Hydraulic System Issues:
• The hydraulic system, including the clutch master cylinder, slave cylinder, or hydraulic lines, could be leaking, damaged, or experiencing air bubbles, resulting in a harder pedal feel. Inspect for any leaks or damage in these components.
• Clutch Cable Issues (if applicable):
• If your Fortuner uses a mechanical clutch linkage with a cable, the cable could be stretched, frayed, or damaged, causing increased resistance in the pedal.
• Clutch Release Bearing:
• The clutch release bearing may be failing or worn out, causing increased resistance when engaging and disengaging the clutch.
• Clutch Fork or Pivot Issues:
• The clutch fork or its pivot may be damaged or experiencing increased friction, making the pedal feel harder.
• Pressure Plate Issues:
• The pressure plate, which engages and disengages the clutch, might have issues like wear, warping, or damage, affecting the pedal feel.
• Flywheel Problems:
• The flywheel could be worn, damaged, or have hot spots, affecting the clutch engagement and the pedal feel.
• Improperly Lubricated Components:
• Lack of lubrication in the clutch linkage or pedal assembly can cause increased friction and result in a harder pedal.

Conclusion.
It's essential to address any clutch-related issues promptly to prevent further damage and ensure the safety and performance of your vehicle. It's recommended to have a professional mechanic inspect and diagnose the specific cause of the harder clutch pedal in your Toyota Fortuner.

engaging?
you meant dis-engage im sure.
pedal up is engaged,
pedal at floor dis-engages it.
my guess, is the clutch drags unless i push the clutch pedal 100%
to the floor.
1: bad cable is 90% cause. non last this long.
2: no free play is way too loose.
3: broken lever on the pedal top. caused by #1

THE BRAKE CLUTCH PEDAL BRACKET WILL SOMETIMES LOSTEN UP BECAUSE ITS BENT OR WORE OUT BUSHINGS.LOOK UNDER STEERING WHEEL FOR SLACK OR SLOPPY PIVOT POINTS!!

Clutch slave cylinder. Or master cylinder are leaking

Clutch plate and pressure plate seem to be too weak to pull the car. To test the clutch plate, park the car on flat surface. Pull the hand brake up, start the car, depress the foot brake pedal, depress the clutch pedal, put the car in 1st gear, press the gas pedal and leave the clutch pedal at once, while keeping the brake pedal depressed.
Follow one of the two following statements:
1. Engine does not shut down and remain start. (Clutch plate, pressure plate and clutch bearing defective - Replace all as a set)
2. Engine shuts down. (Clutch system is OK and does not require any repair).

sounds to me like the clutch master cylinder might be bad usually this happens when the line or the clutch master cylinder leaks fluid and you lose pressure to your clutch pedal...you should have a hydraulic clutch on this truck...if its leaking it will need to be replaced its located under the truck usually on the drivers side mounted on the transmission bell housing...hopes this helps

The problem is on your master and clutch slave cylinders. You said were dry and put clutch fluid. Wont do the proper job for clutch work as the inside rubber seals are not strong enough to make the pressure needed to release the clutch.

this sounds like the clutch slave is goin out, this unit is on the outside of the transmission. Possibly losing pressure!! Your transmission does not use transmission fluid, but instead gear oil. Have the following checked:
1. Clutch Slave (possibly worn)-this will cause soft or hard clutch pedal feel, slipping clutch, unintended clutch release, hard gear engagement, no/insufficient clutch movement.

*2. Clutch pedal Mounting Plate (possibly cracked)-this will cause improper gear engagement, hard gear engagement, soft pedal feel, insufficient clutch movement.

*this plate is located above the clutch pedal itself, apply pressure on the pedal with one hand while inspecting the plate for fatigue cracks(use a bright flashlight). This is very common on these models. This problem will eventually get worst and most mechanics never figure this out.

if it happen all of a sudden then its most likely the clutch slave cylinder.

Two things, first does it slip at all? If you put it in high gear and hammer it, does the engine rev up? If so, you may have a spring problem causing the clutch to not fully contact the pressure plate and will result in this problem.

Is the fluids in the master cylinder full? Do you have a leak? Bad pressure? I'd check those before going on to more difficult remedies.

Personally, by the way you're describing it, I'd say it's a spring. Especially since it's engaging and disengaging correctly. Maybe an adjuster somewhere came loose? I'm not sure with the Explorer, but I know my friends `00 F-150 had an adjuster snap causing a very similar problem but the clutch just wouldn't grab at all due to his problem.
