Ok, It was a frigging mess as I expected.. I ran a 1/2" Vinyl hose from the top of the bleeder to a glass vase. (I hope my wife does not need that again )

Anyway.. Picture one shows what color the fluid was... There was much more fluid but.. That went all over the garage floor That vinyl hose did not seal too well..



This second picture was with a light underneath it.. WTF!



The last one is a video of it swirling..



I refilled it with Valvoline Synthetic


So the bottom line.... FLUSH THE SLAVE.. This is where the proverbial Rubber meets the road..

Now.. on to the bleeding of the air.. THANK GOD FOR THE MIGHTY VAC... IT took quite a bit of sucking... but I got all the air out... I left it on about 25 on the vacuum setting.. and kept waiting for the bubbles.. Added more Fluid and then pumped the clutch.. I even slid my foot off the side of it and let it snap up.. That seemed to unleash a torrent of bubbles..

I must have pumped that pedal 200 times... Pedal feels Firm and high.. I have no idea if this is going to equate to my clutch woes going away.. But I will post my results once she is on the road...

I read somewhere about not using synthetic brake fluid as it ruins the seals. (Specifcally DOT5). I use Motul 600 RBF.

Maybe somebody else will chime in.

Tons of folks using the Synthetic Valvoline.. I've used it on the brakes of my daily driver with Zero issues..

Synthetic is fine. Silicone is not (DOT5).

VALVOLINE SYNT. IS trash.....

Get some decent brake fluid is not all that expensive...

That didn't look to good Charlie! I am hoping since mine is an 04 the turkey baster method every 6 months or so will keep it clean but mine did look pretty bad after just 2 1/2 years. It been a few weeks since I sucked it out so I'll have go out and check to see what it looks like.

There's a random comment..Not trying get into it but...Please back that statement up with facts please as to why exactly it's trash? It cannot be more trash than the crap I pumped out of the slave?

The point of my post was not to ask permission to use Valvoline.. It was to encourage more folks to purge their slave...

Bottom line, what did you have to do to get the hose on and flush the system.

chuckster

I had to literally squeeze my hand up in there and slide the end of the hose over the bleeder..

The downside is this..

The bleeder is a 7/16" Why? I have no idea.. the rest of the car is metric..

The head is hex shaped.. so there is still space to leak with a 1/2" hose.. I was just hoping to get the bulk of the fluid into the jar.. but alas.. I think I only ended up with half.. The rest on the garage floor..

Found something else out..If you continue to pump the pedal after the slave is empty, It does not continue to suck it out of the Master.. I have no idea why...I was hoping to keep it flowing but it did not cooperate...

Even tried to get that little pin head vacuum adaper to fit into the little hole at the top of the bleeder.. But not enough room

I cannot say enough what a crappy GM design this whole setup is..

I did not mean to cause any problems, I just remembered someone using synthetic and that it caused a problem, the other post stated that it is the silicone based products that cause the problem.

By the way I believe the bleeder is an 11MM.

chuckster

No offense taken.. I just wanted to know if there was something that I did not know about Valvoline.. IT is NOT silicone based that is certain.. it's DOT3/4 compatable..

And yes.. Thanks on that 11mm... I only had Metic Wrenches.. and it fit perfect.. I was told that it was 7/16". For the heck of it.. I slipped a 7/16"Socket over it and it also fit perfect.. I guess those 2 are very close..

MYCoupe

Yes they are very close 7/16 = 0.4375" and 11mm = 0.4331"

DPG

looks like i could have been amused for a little bit swirlig the old fluid around and with the light underneath. haha

I looked at it from the metric side. A 7/16 is just a shade bigger than an 11mm at 11.1125 mm.

There is not a thing wrong with Valvoline synthetic.

vetterlatethannever

Makes me wonder about mine... Any link to the procedure you used?

Curious, have you used Valvoline SuperSyn in a C5/C6 clutch?

Reason I ask is that I tried it in a C5 Z06 clutch and found that the Valvoline SuperSyn leeches to black almost immediately and makes the clutch pedal squeak loudly. Within a short time I found it necessary to bleed the clutch hydraulics to get rid of the Valvoline.

So the Valvoline SuperSyn may be OK in the brake system, but I sure found it a poor choice for the clutch hydraulics.

Is there any way to make a hole on top of the tunnel from in the car to access the bleeder? Just a thought

craig04c5

You must have owned a 428 Mustang as that was the only way to change the spark plugs without pulling the engine.

I use Motul 600 or Ford HD fluid whatever I have on my shelves at the time. Keep it clean it makes a huge difference in how these cars perform.
