Any such thing as clutch adjustment?

Back from a weekend trip to Scottsdale,Az and noticed the clutch pedal has softed over the first several hours of driving. Seems like everything gets smoother during the first tank of gas.


When pushing in it seems the pedal does nothing for 6-8 inches. When letting it out, it grabs only a 1/4 inch off the floor.


If it were a cable (could be for all I know), like on most motorcycles, I'd want to tighten the cable.


Any adjustment like that?

I am guessing not. Best to take it in. I had a similar problem on a Mercedes. I had to take it in numerous times, hopefullyPorsche will get this right the first time for you. It's not a great feeling, especially the day that the clutch pedeal doesn't come off the floor.

The clutch is most likely hydraulic.......which means there are not many adjustments to be made. Most Porsches do have some sort of adjustment at the clutch pedal though........on some models you were/are able to adjust the return spring point to make the clutch either lighter or heavier to a certain degree. I don't know yet what the Cayman has though.


There is a possibility that there is air in the clutch hydraulics......pretty common with these type of clutches, have your dealer take a look if it concerns you......they should be able to tell right away.

The clutch on all Porsches is hydraulic now, and AC is correct, few adjustments can be made... they might be able to slightly adjust the pedal travel, but that's about it. As the clutch wears-in, the contact point will move out some... you'll get used to it, though... my turbo started out that way and changed some, but not much... if it begins to change a lot, then you're getting a lot of wear. I've gotten used to it, but it's really different when I've driven the Honda Insight for a while, and then hop in the Porsche.

Yes, hydraulic.
Yes, non-adjustable.
No, air in the system is not common, in fact, very rare absent a ham fisted mechanic or physical damage.

Well, maybe not too common in new cars......but having owned 4 olderPorsche models, a leaky master or slave clutch cylinder and/or line is quite common. Havingimproperly bled clutch hydraulics from the factory would be rare, but not impossible.

It degenerated rapidly over the last 2 days. When new the pedal came off the floor about 1-2 inches before the car rolled forward. Then about 1/4 inch, then 0 inches, then you couldn't get it into gear... Has to be faulty clutch hydraulics. In a few more hours it would need a tow truck.


I was wondering why I kept stalling it and shifting smooth was difficult! :) Actually it really helped me learn it quickly… I can shift real smooth now!


The passenger side air bag also does not function. Error on the dash and light stays on even with heavy passenger.


Other than the broken stuff the car is wonderful! When you use the pedals hard and turn the wheel hard nothing bad happens. It oversteers or understeers in a super predictable way. All the talk of infinite grip had my expectations a little off. To me it feels like it slides easily because it is so easy to tell exactly where the limit is. Easier to control the any other car I've driven by far. I love the PSM, but I have hard time believing the claim you can go just as fast on a track with it turned on. I've only played with the Sport Chrono in Sport mode once or twice though. Noticed the throttle change right away, does make the car feel faster.


I know everyone wants a comparison between the yellow brakes and the red brakes. Me too! I haven't driven the red brakes. The yellow brakes are amazingly powerful. Not just a little, but a lot more powerful than any other vehicle I've driven. The time between hitting the pedal and ABS coming on is almost instant. They feel like new sport bike brakes. They have good feel at speed, very easy to adjust small amounts of pressure. At very slow speeds, like parking, they are grabby.


Everything is exactly as it should be . The brakes and feel on turn in are my favorite parts.


Nit picks- Seat belt dinger must die! Can't see anything looking over left shoulder. Radio buttons, who needs 10 or 12 presets anyway? Getting in and out, especially with door partially open, is a pain. People, myself included, kick the door or dash sometimes when getting out. The window crack feature should work with the rear hatch too. You have to remove and replace the key if you stall it. You can't hold the bottom of a 3-spoke steering wheel. Super low- scrapes easy. Not bad….. :)

SF, I forgot to answer your range question Short answer- I didn't pay attention! :) But I can say for sure it's significantly less than our C3s. I was driving heavy footed, playing with car, so... it was short on that trip. But if you set the cruise control at 70 I bet it could break 300 miles per tank.


Oh by the way, I put 1/2 tank of 100 octane race gas into an existing 1/2 tank of 91 Premium. Big difference insmoothness, especially at low rpm. Sometimes it would knock a when stabbing the throttle hard from low rpm, like when double-clutching, or if you lugged it evena little in first gear. And it wasn't specific to one tank of gas. It says 93 minimum in the manual, but 91 is the best available in most states. The better fuelhelped this car more than I expected. It made more difference than in either of my motorcycles and you can barely tell the difference at all in the truck. I think it's worth experiencing... I'm going to try some octane booster additive, but I've never felt a difference with that stuff.

At the Union 76 at I-5 and LaPaz, on the pump closest to the corner. I think it's unleaded, but if I run a lot through it I'll find out for sure.


Cool, we can meet as soon as I get it back! Service said they wouldn't even look at it until Monday.


Never even noticed any leaks. Must be a puddle of fluid somewhere....

DITTO to all of that!

CM, you've got PCCB? Me too, and they really do rock hard. I would not buy a Porsche again without them. The stopping power is wild, but the ride quality is the big story. My PCCB do not grab at all at low speed (possibly due to 400 miles of very calculated pad bedding). In fact, at low speed they are remarkably "un-grabby". My '06 550i Sport BMW's massive stoppers are a little grabby but very strong, and my 545i Sport's were a bit grabby too, even though the 550's front brakes are bigger now, so I know that the little "snatch" at the end of a roll-up can be annoying. PCCB brake modulation is on a HALO level with my race bike's Brembo GP calipers and full floaters, that is to say, they can be no better. The PCCB's will last for the lifetime of the car, just as long as you don't damage the rotor when swopping wheels at a track day. The best part of the whole deal is (since the "big reds" are killer brakes too) the unsprung weight, and how the ride is so much improved. I am now routinely using Sport mode constantly, the "normal" position is too soft. This is not the same ride quality as the "big red" equipped cars. My 997S was torture on the same roads in Sport mode. $8000 well spent, considering Brembo upgrade kits can start around $5000, and they are steel. PCCB will also register a higher HP on a rolling dyno, as there is less resistance to acceleration, due to the 50% lighter weight. PCCB makes a quicker, as well as quicker stopping Cayman S, and of course they look sharp too. I love these brakes, they're just damn good.

I think you're right. I made the grabby comment shortly after getting out of my GMC Sierra in need of a brake job. I agree that modulation is excellent and I take it back... :) Ijust wasn't used to so much stopping power with such a light car.


I still haven't driven any other Cayman but mine. I'd still like to meet up with MP, I don't think he has PASM though.


Have you driven a Cayman without PCCB as well as the 997S? I'm wondering if the superior comfort might be in the model and not the brakes...


What kind of bike do you have?
