Bleed brakes and f1 fluid with no sd2?

The ABS has a separate reservoir so typical bleeding processes won't clear everything. I guess you could do it by bleeding the brakes. Go for a drive and lock them up a few times. Then repeat the bleed process.

As for F1, you can clear a couple of the lines because you can go to N, R, 1, and 2. Without an SD you can't cycle the actuators that will get 3,4 and 5,6 so you can't clear the old fluid. Like the brakes you could do it twice and probably get it done.

 

Max- The coolant should be flushed and changed every 2-3 years. Change interval is not in any of the late model Ferraris, for whatever reason. Permanent anti-freeze is a joke. On your brakes, no sweat with bleeding. Assume you are doing an annual change, so remember to bleed the clutch system, too, and there is also a bleed for the master cylinder. F1 fluid does not normally need to be changed, just topped up. Here is the latest tech bulletin on how to top off the F1 fluid.

Terry, F1 and P.S. fluids get pretty hot and should be changed. We suck them out and refill during fluid changes. Complete draining is not required. The constant infusion of new fluid is enough.


On the F1 and ABS systems. "Changing" fluid does not require the SD. "Bleeding" does. They are distinctly different operations.

 

Brian- Thanks. I had not seen that before on the F1 fluid. Pulling it out seems a good way to proceed without having to bleed every time. How often, since it is not spelled out in any tech data?

I change my P.S. fluid every two years. Last time put in Dexron VI and that proved to be a mistake because I now have slight weeping from the seals. Back to Dexron III, I guess. What do you use for power steering and F1 fluids?

Ferrari uses the Shell donax TA for power steering fluid.

 

Brian,
Im planing on upgrade my front brake system. Two months ago a change my brake fluid and bleed the system. My question is; Do I need to replace the brake fluid again and bleed the system again? Im trying to avoid the SD2 thing.

 

Last time it was at the dealer. But here you need like two months of waiting to get a appointment. That is why I really need to know if I can install those new brake system without use that damm computer

 

D- you do not need to use an SD2/3 for what you are planning on doing. I am replacing my front brakes with MovIt ceramics and an SD2/3 will never get anywhere near my F1 575M during the swap.

That is what I need to know!
Thank you guys Taz and Max

 

I agree with Terry. After disconnecting the lines cap them off with something to prevent the system from going dry just from the leakage. Then bleed as normal afterword.

 

We use Redline D4 in steering. It's a Dex3 equivalent.

In F1 for late 360 and 575 we use the Tutela.

Seeping low pressure hoses happens to all 550 and 575 sooner or later. The hose is no good. We use a bulk hose from Goodyear we get from the hose shop. It is pretty cheap and a better hose. There is a hose restrictor in one of your hoses that needs to be installed in the new hose.

 

If one wanted to replace their brake fluid with a higher temp rated fluid it would be necessary to have it completely bled with the SD2 I'd assume?

 

Andrew- No SD2 required to bleed brakes, change pads, change calipers, change brake lines, change brake fluid, etc. SD2 very handy for setting PIS on F1 clutches, ECU analysis, etc, but not for this kind of work.

Brian- Thanks for the advice. May ask you for your source of completed hoses one of these days if the Dexron III does not cure the weeping. I hate it when anything is not working perfectly.

Righto Terry. I didn't know if the ABS had to be cycled in order to get ALL the fluid out when changing to an uprated spec fluid. If the old manual way works, all the better.

 

Can an F1 clutch be bled w/o the SD2/3 and if so what would be the proper procedure? Brian mentioned earlier that it is O.K to suck out both the steering and F1 fluids, could the procedure for that be explained also? Can a DEX III be mixed with whatever fluid remains in my steering system (I'm assuming it's Donax TA or DEX IIe) after most of it gets sucked out? Any help would be much appreciated.

Thanks,

Alex

 

The ABS unit holds very little fluid. There is a larger percentage of oil leaft in the motor or trans when changing those. The only way to get it all out is to take it apart and use a Q tip.

 

No

 

LOL!!!!

 

Max,

I believe bleeding the F1 system is necessary in the event of any air in the hydraulic lines. Simply sucking out/refilling introduces a good amount of fresh fluid into the system which as Brian mentioned is often good enough.

What I've always wondered is how air gets in the hydraulic lines to begin with? A loose fitting? Overheating of the fluid?

 

Max- You have to read carefully and I know that is difficult to do in a foreign language. Your English is way better than my Czech, for sure.

What Brian, a real expert, said was: you do not need an SD2/3 for brake work including bleeding. You do need an SD2/3 for complete bleeding of the F1 system, but bleeding is rarely required. Try putting in new F1 fluid and see if it fixes any problem you have. If you still have a problem, take it to someone who knows what they are doing and who has an SD2/3 to do a proper job.
