What is the going rate for a Brake Flush not including brake fluid?

Is it something most of you guys tackle yourselves? Is 1.5L enough to flush and fill?

Couple of quarts should do it. Buy yourself a Motive power bleeder for what you would pay a shop.

I paid a shop $120 including fluid, but that was at the track. I didn't have time the day before to jack with it. Ended up with a flat tire and didn't even get to go on the track

$80 is reasonable for a shop. Just make sure they bleed the whole system and not just bleed a few drops out of each corner.

I think you need just a touch over 2 quarts.

IIRC, it takes a Tech II or similar tool to cycle the ABS module and get all of the old fluid out. That's the best way to do it.
But a basic flush that doesn't activate the ABS will still exchange most of the fluid, and if you use the brakes in a wet parking lot to activate the ABS, that's a little better.

I did mine and 2 pints will be enough to do a C7. Moltul 600 Racing Brake Fluid comes in 500 ml container which is a pint.

2 pints?

I thought i would need at least 4 Motul 500 ml???

What about the ABS Valves or pump motor that GearHead mentioned? Does that need to be done?

Iconic

2 pints.

I've done a C6 GS and a C7 Z51, both 2 pints and both driven hard on Road America, Daytona, Sebring, PBIR and neither car ever had an issue with boiled fluid. Also, I did not do the ABS valve flush tech II on either car.

Complete flush $120 at dealer with GM DOT4 for me last week.

Same. I've never flushed fluid from ABS out either.

Honestly, if fluid gets that hot that high up in the line, it's really not a big deal because your car is engulfed in flames. Once you have race fluid int he caliper and a few feet of lines, you're pretty good. I only bleed a little bit at each track day, maybe two brake pumps per corner, once I do the flush.

I run at ECR, which is probably the hardest track in the country on brakes. It's nothing but long straights into tight double apex turns. In my C6 it was nothing but going from from 120mph down to 50 over and over.

Thats where I boiled my brake lines and ended up in a ditch when I thought I could do DOT3 for at least one session... I was wrong.... Now I am over cautious about how often to flush out the Motul 660 i use now. That course is a beating on the car. Fun though. It will be awesome when they repave it this year.

Well, yeah, running DOT 3 will get you killed.

If you flush with RBF600/660, the stuff in the abs pump isn't going to hurt you.
