2 problems I need answered. 1. Clutch Pedal rattles/light humming sound when not in use but when I tap it or press the clutch pedal in it goes away. 2. When I go over 60km it sounds like the tires are making a loud roaring noise - the car doesn't shake or move erratically. I do have 4 new snow tires on the car? Thank you - 2001 Toyota Echo Base Sedan Manual 109km

when the foot is free of the clutch , sometimes a tinny rattle that comes and goes ( harmonic vibration)
if the foot is resred on the clutch that tinny noise will go or if pressed ******* the clutch a grumble ( possible vibration under the foot) will sound while the clutch pedal is being pressed
may be heard from inside the car but will be heard at idle with the bonnet up

Hi Michael, If the noise changes when the clutch pedal is held depressed the problem will more likely be related to the clutch assembly and in particular with the clutch thrust release bearing. To attend to that will mean removing the gear box which means replacing the plate, cover and bearing will prove more economic. Regards John

It sounds like the hydraulic clutch is failing or the car just has a light clutch feel. I suggest you have a local shop push the clutch and see what they think.

It may be that the throwout bearing is lightly contacting the clutch assembly even when not in use. Check to see if there is an adjustment for the stroke of the clutch slave cylinder at the transmission. It may be pushing the throwout bearing into the rotating clutch assembly.

A rattling noise from the transmission is never a normal condition no matter what anyone says, and the first thing to do is to check the transmission fluid level, but it sounds to me like the throw-out/release bearing is riding the clutch pressure plate, and when the clutch pedal is in the up position the throw-out/release bearing and the clutch pressure plate should not be touching each other, and the only time that they should make contact is to release the clutch disk in order to shift the transmission into gear. There should be about 1 to 2 inches of free play in the clutch pedal, and the clutch should start to grab within 1 to 2 inches of letting the clutch pedal up off of the floor, and if this is not the case you might need to have the clutch properly adjusted especially if the clutch does not start to grab until the clutch pedal is half way up from the floor. Also, the main bearing in the transmission could be going out due to low fluid, or a damaged pilot bearing that is allowing the transmission input shaft to wobble just enough to cause a rattle from the main bearing or even a vibration in the transmission.

this sounds like an adjustment issue. you did not mention the mileage...The clutch is released by a bearing, this release bearing needs to come back off of the fingers of the clutch pressure place, early wear and noise happens.

Near the end of the clutch life, you may find that you cannot release any more, if your model is adjustable.

Start with proper clutch release adjustment.

WITH ENGINE ON & RUNNING and you are able to shift to any & or all Gears and with this theres,
No Clutch Engagement Upon Releasing Clutch
With Info Provided seems that you have 1 or all 3
of the Fallowing and they all Should be Replaced as A Set even if on lt 1 of them has Failed

1. Clutch Pressure Plate has Failed
2. Clutch Disc Is Worn Down
3. Clutch Release Bearing Has Failed

All Require Removal Of Transmission this is the reasoning for Replacing all as SET with the Labor cost if your replace only 1 Item, and 3 Months later another of the 3 components Fail, you have the same Labor cost to PAY.

This Solution is Answering the SOLE Question ask, Barring No other Problems have or did Happen such as Noises Ran out Of Trans Lube. if it is the Clutch that has Failed and you are unable to Perform the Repair yyourself, DO SHOP AROUND get 5 or more Estimates as the Fee Will Vary Sometimes very wide gaps in fee's
and also Try and Purchase the Parts yourself Due to the Tremendous Markup of parts at Shops

I Hope I have Answered you Question to your satisfaction and if you have any more questions Feel free to Ask Me

i have just replaced an 03 civic ex clutch and transmission bearings due to a customer being too harsh on it. It sounds like its got a little life left in it if you are easy on it. 

if there is adjustment in this model use the below walkthrough to adjust it.

adjust the clutch pedal, 

1. if you look up on the top of the clutch pedal, the first thing you should see if a clutch pedal position switch, and right behind it there is a locknut, looens the locknut. once you loosen it, back off on the pedal position switch or adjusting bolt untill it no longer touches the clutch pedal. 

2. now behind the clutch pedal, there is a pushrod. and on that pushrod, there is a locknut, loosen that locknut. Now turn the pushrod in or out to get the desired height and stroke at the clutch pedal. 

The freeplay is the amount of push on the clutch pedal to where is starts to have resistance from the top. I have usually been told it should be set at 1 1/2-2 inches of freeplay.

Once you set it, tighten the locknut on the pushrod. With the clutch pedal released, turn in the clutch pedal position switch untill it contacts the clutch pedal. then turn it an additional 3/4 to 1 turn. And tighten the locknut.

Now on top of the clutch pedal switch, there is a clutch interlock switch. Loosen the locknut on that switch. then press the clutch pedal to the floor.

release the clutch pedal 15-20 mm (0.59-0.79 in) from the fully pressed position, and hold it there. adjust the position of the clutch interlock switch so the engine will start with the clutch pedal in this position. then tighten the locknut on that switch.

Hope this helps 

check the fluid level first, if its empty this will happen, if so full it and bleed the clutch, if not it could be the slave cylinder and failing both, it could be the clutch itself, easiest way to check is to see on the gearbox if the clutch is engaging when you press the pedal down.
just ask if you need more help
