Chevy Owners with a MaxBrake Controller

[homefor2]

Need help figuring out the T fitting that fits a 2008 Avalanche. Should be the same as a Silverado. If you could tell me the number on the brass T fitting or send a picture of the T on the master cylinder, that would be much appreciated. I'm talking about the T that connects the brake line to the Maxbrake sensor at the master cylinder.

Should be same as Silverado, someone gave you a bum steer.

You will be sorry if you let the last good after-market controller get away.

Not the same as Silverado. I know because I tried to get the Silveraldo fitting to screw in and ruined the threads in the master cylinder to the tune of a $200.00 for a new master cylinder. I also got the specs on thread size from the GM parts department and it's a very uncommon metric that even machine shops did not have.

That's strange, I looked up the replacement master cylinders on NAPA, and both were the same number.

Sure wish you could use it, I love mine. You might check with Summit, or Russell fittings for adapters.

Yes I did that but Di was not sure which fitting will work.
