also, what brake fluid do you guys use? thanks

 

Every oil change at least. If racing heavily more often.

 

I check pretty regularly. I would say twice a month. I use the ranger method with the syringe. If it's discolored or dirty I'll flush it out. I race every week so I usually end up changing it every other. I use DOT 5.1 synthetic. I buy mine from a motorcycle dealership. I forget the brand but it's pretty expensive at $16 per pint.

 

You have to be careful using synthetic fluids in these hydraulic systems. We use DOT 4 Non Synthetic here at the shop, works well for us.

I recommend at least twice a month. On my personal car I pop the hood when I fill up and look at the fluid... I beat the living crap out of my daily though, got to keep my clutches in line.

 

SNL,
Why not synthetic? Just curious as to the problems/issues it causes.

 

The seals in the slaves, no matter the brand, are not intended to be used with synthetic. They will deteriorate over time.

 

you guys really change it that often? i just checked mine and it was a golden brownish color.....how bad is that? its been a good 15000 on that fluid. The fluid was a foggy color when it was first put in....the tranny is definitaly the part of the drivetrain that has it the easiest.....i really dont push the clutch in/out that quick at all, and dont rreally shift hard. i wonder how often gm suggests in the warranty part of our manuals? anyway will basically any dot3/4 get the job done

 

I havent changed min in the almost 7 years I have owned the car... drives fine.

 

I use Valvoline DOT 3/4 fluid and change mine out every 2-3K miles or if its dirty.

 

Really depends on how much you launch, power shift the car as to how quickly it gets dirty. The hydraulic system on the t56 is already handicapped enough and I just like to ensure that everything is working to the best of it's ability. You can run any 3/4, but the higher the boiling point the better. Prestone Dot 4 is the highest non synthetic that I know of and is what I run.

 

I'll be looking for this stuff next, where do you get it from? The pedal feel in my car compared to what I remember it was in my old '97 Z28 M6 is much softer and gets softer over time. I dunno if different fluid will help but with uncoated LT's I imagine the fluid handles a lot of heat.

 

Unless you're heavily racing your car I see no reason to change it that often. Every oil change? Twice a month? Come on guys.....

I have had mine in for about a year and a half and have about 15-20 passes and it's still clean and everything is working properly. Changing it reguarly won't hurt anything but it seems a little excessive. I have worked on cars that are 5-8 years old and the fluid is still good, I usually recommend a flush(a lot of people never consider clutch fluid when thinking of maintanence) but for the most part it's alright. And this is coming from someone who has access to a pressure bleeder that once it's set up takes, no lie, about 7 seconds to bleed the system.

I use DOT 4.
