Flushing the brake fluid issues. Brake failure.

No, it is just that GM recommends dot 4 for the track vs. dot 3. I am guessing it is based on boiling point. I am not sure but wondering if the dot 3 began to break down from excessive boiling?

I'm not sure. My guess is that it mixed with with the Dot 3. Why do you say new master cylinder time?

boiled fluid does not cause clogging or coagulation of the fluid...that is a guess from the one who posted

I was just asking if it was possible, sorry for the confusion.

Anyway I took it to a local hot rod mechanic. Trusted guy who knows what he is doing. I was going to do it myself but did not have access to the Tech II machine or whatever it is to pulse the ABS to clear fluid through.

Later in the day he gives me a call and says he is having problems getting clean fluid to the passenger rear caliper almost like there is some type of obstruction. He used a power bleeder and still was unable to get clean fluid through. His friend who lets him borrow the Tech II machine is a GM mechanic and they called over to the East coast and talked to one of the head mechanics that works solely on these cars and Corvettes. That mechanic stated that it is a known problem when the cars are tracked and that the line may need to be replaced. GM has my VIN and have noted that it may need some warranty work regarding this.

He gave me the car back and told me to put it through same heavy braking and let him know how it feels and if its not right he will take it back and get it sorted out free of charge.

On the way home the pedal felt a little spongy but traffic didn't allow for proper heavy braking.The next day I put her through her paces and sure enough the brakes failed again.

I am dropping her off tomorrow and he will have it the next week and a half while I'm on vacation.

My question to you guys is has anyone experienced this before? What do you think?

The fluid was replaced with new Motul RBF 600. I am thinking of getting the Tick remote clutch speed bleeder to help rule things out.

PS: it should be noted that regular driving and even some hard stops the brakes work (feel a bit spongy but no horrible). But after repeated hard braking (smoking front passenger caliper) they fail.

How is installing a remote clutch bleeder going to help your brakes? Do you know what this is?

The clutch and brakes use the same fluid and reservoir. Being that we could not get a clean bleed I am hoping this will help eliminate one of the variables and get all the old DOT 3 out. Plus it will just make it easier to bleed the clutch in the future allowing clean clutch fluid before a track day.

Putting a remote speed bleeder from Monster was one of the best mods I done, takes more time to pull out the Mity and compressor than to bleed the clutch. Literally about 40 secs.

I really need to get a remote bleeder for the clutch as well. Just scared to mess with the tranny to do it. lol

Speaking from experience, you certainly don't want to pull the trans just for a remote bleeder, I was already in there with new flywheel, clutch and slave cylinder.

The seals can possibly become contaminated by dissimilar fluids and may leak over a period of time. The brake pedal starts to feel spongy. That is what I was told when my brake guy changed and bled my system from Motul 600 to Castrol SRF.

You can do it without pulling the trans

Thats not correct at all. Now you will have issues going from Dot 3/4 to Dot 5. Dot 5 is not compatible with OEM systems.
