Hi there,

What was the problem with the brakes before?

Did you perform a manual bleed to all the wheels and then an ABS SYSTEM bleed with TECH2 etc?


Customer: replied 1 year ago.
There was nothing wrong with the brakes . Took vehicle to a nearby Firestone , the technician said to replace the master cylinder. Which I did and now having trouble with the brakes so really don't know if one thing had anything to do with the other.
Expert:  Gary replied 1 year ago.

I would be taking it back to him.

Why didn't he do the job?

Now you are in trouble.

Sounds like you can't drive it now, I would recommend you take it to a Chevy dealer, on a towtruck.

They have all the tools.

Some of which you and an average workshop don't have.
