Gathering parts for some track days this spring. Going to do fluid, FVD stainless lines, tires....
@AdamSanta85 why do you think Motul 600 won't last a year?

It doesn't last more than a couple of days if you're pushing the car on a track with a couple of heavy breaking corners. I used.Motul 600 and would bleed the calipers off after just one full day sometimes to get the pedal feel and braking back to tip top.

While getting an alignment done I had the shop flush my brakes and have used Brembo HTC – 64 ever since.
bleed them once year, maybe and additional time during the tax season and that’s it

@911mhawk I appreciate hearing your experience! And would love to hear from others as well!

I have used Motul 660 for years. It has been extremely reliable. https://www.motul.com/th/en/products...0-factory-line

I do think it will.

What I was trying say was I wanted to try the Endless and Castrol, and my requirement is I need a fluid that’s good for at least a year.

I ended up taking a liking to the Endless.

I’ve ran Castrol SRF in everything I’ve owned since discovering it in 2003 with my highly modded and heavy BMW ///M5.

It is the only brake fluid I have never boiled.

That is a feat. I have disintegrated brand new OEM pads in 3 x 20 min sessions. I have turned two sets of Brembo GTS BBK 380 front and rear PINK, and still not boiled the SRF.

I hear good things about Endless 650 and Motul 660, but until I boil SRF, I won’t change.

I just pulled the trigger on these. Will run with RE10 pads.

I track in Southeast - humid. I want high WET boiling point fluid and don't want to change fluid constantly. Castrol SRF wet BP is 518F. Enuf said.

Turn this

Into this

Twice


When I can do this twice and still not boil SRF, you know I will never use anything else.

BTW in the first seven days of. Ownership, on a street spirited run, car brand new and completely stock, I boiled the factory fluid. 🤣

Let me please ask a dumb question. The answer is IT'S BRAKE FLUID. But sincerely I'm interested to learn when it's time to upgrade from Pentosin to a fluid like SRF. First HPDE event? When you move into the intermediate group? First time you feel some squish in the pedal? Once you've upgraded to a track focused pad?

Any of the above. Why wait and boil the fluid and run the risk? I boiled the stock fluid in the first week i had the car on the street. Don’t wait until something happens, prevent that **** from happening.

I've been running the Endless RF-650 for a couple of years now. So far it's great. I use a brake fluid water content tester and change the fluid annually with my oil. At fluid change time, there is still essentially zero water content after a year and a few track days. Subsequent flushes only use one can.

I am going to change my new to me T over to the Endless in the next month or so in prep for upcoming track days.
