Clutch/ clutch pedal Vibration

[Drozdy]

OK guys so here's the situation: i have a Mazda 3 gt 2009 and ive been having problems with my clutch pedal assembly for a good while now...

It was creaking and unsmooth, went to dealer about 6 times for this.. once they greased the shaft - didnt work, another time they replaced the slave cylinder, worked great for about 2 weeks, then started again - they replaced the clutch bearing while they were doing transmission work (syncros), same story again: 2 weeks later it started again.. so i went in pissed and they changed the master cylinder..

Now for 2 weeks it was perfect, but now the pedal vibrates right at the top (just above the engagement point, ie when you just put your foot on the pedal) there is no creaking sound so thats fixed but the vibration is annoying as hell.

So, when the car is cold, its hardly noticeable, once it heats up, its there and stronger if i press on the gas. Went to the dealer and they say its not obvious enough for them to figure it out.

Ive researched a bit and found out people get clutch pedal vibrations often and found it to be fixable with a motor mount or inserts - so i placed an order.

Any ideas? Suggestions? what could it be


OH and PS while im here - ever since i got transmission work done, when i shift from 2nd to 3rd i quite often hit the (fork?) between the 1st and 3rd and in order to get it in properly, i have to put it in neutral and then 3rd- SOLUTION? PLEASE?

I had a creaky clutch pedal as well last year. There's a thread somewhere around here, but I went into the dealer and had the assembly replaced under warranty. All was good after that.

Good luck!

Thanks! will need it

anyone have an idea?

Ok well here's an update: i got my Corksport RMM inserts last week, easy install and I must say that the difference is astonishing! Shifting is crisp, no pedal vibration, clutch engages smoothly and just the whole feeling of the car is much more precise and direct - and oh, zero to none vibrations even at idle.

Best 35$ i have spent in my life and I must recommend upgrading the rear motor mount to anyone

Glad to hear man!

Just a question though...I'm looking at the RMM insert on the Corksport website and I'm not sure what the insert does exactly. If you have engine movement, dont you have to replace the motor mount altogether? From what I'm reading, the motor mount insert fills in the gaps made by the mounts themselves?

If someone can explain it more clearly to me that would be awesome haha

The RMM insert is shaped in a way so that it fits in the stock mount and aids in providing a more robust mount.

Exactly - it fills out the empty space around the "rubber" of the mount which in return provides for less movement and increased rigidity
