How soon after your " Break In Period " was over did you do your first check up?

[WillyDaP]

I am in the phase of doing the 2000 mile break in period with my Cayman GTS but this is a question that is pertinent to all new Porsche owners, as I imagine there has been varied advice from Dealerships, Forums, friends, etc. I usually follow break ins to the letter as I will be tracking my Cayman as I have done with almost all my cars, and since the first service/check up is free what have folks felt was a necessary time to get the this done? Keeping in mind I will be tracking very soon after I get the break in over and normally I would just change the oil , flush the brake fluid ( put in Motul ) and go through other things , but with the detailed time needed to change oil, etc. have most waited a bit longer before they did the first free service. Appreciate your thoughts and glad the first visit to the Dealership is free as that leaves a bit of funds that can go towards camber plates, wheels, sticky rubber air filled donuts, and more. Sure it won't cover much, but it does help a small amount, ha!

I followed the break-in recommendations although I looked at the RPM max as more of a soft limit, meaning I didn't panic if a PDK driven auto downshift or similar pushed past the max occasionally. This was especially true once past the first 500 miles or so. I varied rpms, varied speeds, and varied driving styles which are my keys to proper break in. However, I did avoid anything that would be considered aggressive regarding engine speed, loads and such. Nothing sustained either.

First track day was at NCM and the odometer clicked past 2k on the drive to the track. I changed the oil after that and also flushed factory brake fluid out, adding Motul 660 in its place. Did a few other minor things at that service. However, I didn't use my free first-year service for that early visit, saving it for when the car was actually a year old and due for its initial annual. For me, the annuals for the GT4 are due in December (in service date is Dec 20th) after track season is done so it works out well.

I will definitely do the brake flush and I religiously use Motul 600, as I change after every weekend if running both days. Sounds like a good plan you followed and wondering if any others have any different views or different experiences?

[blueline]

Based on the other message and question you had, I've never used the Motul 600, so I have no answer as to which is better based on experience, not that I would be able to tell anyway. Looking online, probably a chemical analysis and scientific testing would be the best way to tell the differences.

Both are excellent for racing applications per what I've read with the 660 having a higher boiling point. That being said, the 600 may be the better of the two based on some comments.

Motul 660 was what was recommended to me, so that's what I chose, but either one is fine for what we do, or at least for what I do. Motul's racing brake fluids (600 and 660) are considered elite, among the few very best brake fluids available.

[WillyDaP]

Oh, I do agree as I have been using Motul for over 25 years and just wondered if the 660 really provided even better protection in your estimation, but you have only used 660 and I have only used 600, so comparison sounds a bit difficult , ha,ha!

Since we are discussing brake fluids I have been using Motul 600 and 660 for 15 years but recently have purchased a can of Endless RF650 as the stats show some clear advantages.

I always prefer to buy locally and Motul is stocked at several places local to me. On my next flush I plan to use the endless... that I had to purchase online.

Regarding the first checkup and break in, I have always been a drive it hard and get the rings to seat as soon as possible type of guy.

Interesting link to the Build Journal blog and the brake fluid analysis. He's a BMW guy which is fine but I think the comparison dates to 2018 or earlier (I smiled at the "under $20" regarding the category 2 fluids - those days are certainly long gone!), and he didn't divulge the source of the analysis even though a commenter had asked for it, so it would be helpful to see that, plus updated, current tests and the methodology for the bar chart conclusions.

There was another link in the Build Journal piece that I liked better because it had more specific data (as opposed to the 1 to 100 likeability scale bar charts that I cannot quantify). Presumably the second link (below) was gleaned from the manufacturer's data.

I used Wilwood's EXP 600 with my Wilwood race brake setup in the Z06 and it performed flawlessly. My take on brake fluid, both the safety aspect and for superb on-track braking performance, is to bleed often and to bleed significantly.

Regarding break-in, I broke in my C6 Z06 pretty much the way you described. I mostly broke in the factory LS7 on track. The next motor for the car, a Golen na 600+ crank hp (engine dynamometer) race motor was totally broken in on track once it left the builder's engine stand (where it did get some break-in time). (The car was not registered nor legal for the street.)

I have been privy to trying so many brake fluids over the years when at my last place of employment , since we had a Motorsports Division within the Dealership and after using about everything out there it seemed we always wandered back to Motul, because as noted, it is always easier to find and always rates in the top group for brake fluids. Like Blueline I am a keen advocate of constant bleeding and that comes more from having many Pro or Championship Drivers as friends/customers and it is simply gospel for them. I too am a believer ,as it has kept me safe over all the years and kept prayers against brake loss at a minimum......can we get an Amen, ha!?

[blueline]

Amen!

[J-Dub]

Agreed, get that stock brake fluid out of there! Get some track pads and let it rip!
