I see the note about using one bottle of Castrol SRF all year and further that you just bleed the caliper not flush the system. That seems great, but does the open bottle not absorb too much moisture from the air once the bottle gets partially empty?

Second, I have seen many posts saying you can put the 18" 315 v710s on stock z06 rears. I run TT and have a stock suspension and stock rear brake ducts. Under heavy cornering, do you guys that run this combo get any rubbing on the fender or brake duct? I read all threads but couldn't find that exact combo question asked/answered.

Thanks!

Yes. I have no idea how much it absorbs, but it will definately absorb moisture at a higher rate than sealed. I try to use an entire pint in a weekend for this reason. It's not expensive.

No idea about the second Q.

The SRF Fluid is actually not sealed at all from the factory - that's the reason you can go a season on it -- the wet boiling point is over 500 degrees.

thanks freefall

2 bottles of SRF will do. One to flush your system as you can not mix SRF with other brake fluids. then just bleed the calipers before each weekend.

I've only known one guy that ran that combo...and that was a while ago. I don't recall whether he used a wheel spacer or not. Considering how much clearance is there and that it comes stock with a 295mm wide tire, I doubt that an extra 10mm on the sides (20 extra total) would have any issues...especially if it's still at the stock ride height. If you've lowered it, that could be a problem - in more ways than one.

Thanks... I think i am going to give it a try. I will post the results either way.

Au Eng,

I saw your post about SRF in one of the myriad of posts about brakes

That style of changing/flushing works alot better for me since I never have time to really get everything done.

How many pumps do you say it takes to bleed just the caliper?

AU N EGL

I use the Motive Power bleeder and put 12-15 psi into the tank, then bleed. After all four calipers are done, I refill the MC and pump the brake peddle a few times. ( car is on 4 jack stands)

if I may suggest never work too fast, make sure it is done right and safe.

Thanks provette67, knowing someone else has done it with no problems adds some peace or mind.

I now run 315x18 710's on all four corners with no problems.

Also, about the SRF: Haven't had one single problem with brakes since switching to SRF and Wilwood H pads.

Just so you know, I run the 315/18 V710's on the on Z06 rims on my coupe, and I have no issues.

....and my Z is lowered on stock bolts. No rubbing.

So the "no mixing" doesn't include when you first put the SRF into the system if you push SRF out to all the corners and then bleed everything? How can you tell when it's non-mixed SRF coming out at each corner?

I've always run Motul 600 so I'm trying to decide if the pain of "no mixing" and the expense of the SRF is worth it. Atleast with SRF an opened bottle isn't junk.

SRF IS compatible with other fluids, but any other fluid mixing with SRF will lower the BP accordingly.

I bled through about a container's worth for the first time, and then smaller bleeds thereafter.

John Shiels

went 990 track miles no bleed on srf don't recommend that much in any case.

AU N EGL

Color change of the new fluid.

gkmccready

Er, yeah, but with only 2600 miles on my car I'm thinking that the fluid I push from up near the master cylinder is going to be looking pretty darn new. :-)

This stupid little voice in my head is saying "flush with super blue, then flush with SRF" ...

AU N EGL

Open the MC you might be suprised how much it looks like cola already.
