Bedding in a new clutch...?

Gday guys,

Pick up my 6MPS tomorrow with the new OEM Clutch and Dual Mass Flywheel fitted.
Now ive heard a few different views out there whether or not you have to bed in or run in a new clutch or not.
After ive fitted previous cars with new clutches, (whether they be button like my S14 had, or stock \ HD ) ive never been told or had to bed in a clutch.

Any opinions?
Any help?

I will ask the dealer, plus my Mazda Dealer and Adelaide Clutch (Extreme Clutches) but all the help info and discussion is good :)

Cheers :)

The friction material in a clutch is similar, and in some cases identical, to brake linings. So the bedding-in method is the same, i.e. drive the car completely normally.

The bedding-in procedure you hear about for brakes exists for legal liability reasons, it's actually harmful to the brakes.

As he said before :)

Since we're off topic; it's true that brake pads (and rotors) need to be bedded-in, but the bedding-in procedures you hear about should really only apply to racing cars. Street pads are often at risk of being damaged by attempts to follow a special bedding-in procedure.

The underlying problem is that new pads are vulnerable to 'green fade' which means they will experience severe fade at lower than usual temperature, until they become stabilised. Brake pad manufacturers are concerned about motorists potentially having a collision while driving on new pads that fade because they haven't yet stabilised - so they prescribe a bedding-in procedure that stabilises the pads in a very short period of time and relieves them of liability.

However that's not the best way to stabilise most street pads. It's better to do it gradually by just driving around normally and avoiding situations that might cause fade. Pads will generally perform more consistently and better over the long-term if they are bedded-in gradually. Should only take around 200km of normal driving.

No wonder my new pads on my old S14 went dead after a few weeks ;) lol (i was told to 'bed' them in by slamming on the brakes etc etc etc)

Cheers

(BTW still haven't got my car back, they didn't tension the flywheel bolts properly so apparently the clutch pedal was so stiff it took 2 legs to push it down.. So they have dropped the box AGAIN and re done the flywheel bolts and i pick it up today...
WOW, thats a pretty big stuff up i say?)

Sure is, turning 2 days work into 4 days can't be good for the old performance appraisal.
