Question about 2002 Chevrolet Blazer
No breaks ather line breaks fix line still cant get a patel it has abs all so
After you fix a brake line, you need to bleed the line. There is air in the line that needs to be bleed out of the line. Make sure the vehicle is not running, totally shut off. First - find which tire the brake line goes to that you just fixed. Two - then have someone in the vehicle pumping the brake three times, then on the third time, have them hold the brake to floor. Three - open the bleeder valve on the brake caliper of the tire that the brake line goes to.(Note - You need the tire off the vehicle to do this.) Four - once the the bleeder valve is opened, and all the brake fluid, and air comes out, close the bleeder valve and repeat the whole process several more time. Each time you bleed the brake line you are releasing the air in the line, and creating pressure with just fluid in the line. Usually three to four tries of bleeding the line will solve the air in the brake line problem and your brake pedal will become hard.

"have put all new breaks, lines, sensors." For the Mechanic to get the brake fluid in the line to the calibers. It has to be pump by stepping on the brakes pedal. You said "no breaks" so that did not happen.
My question is does the master cylinder work? A lot of work was done that was not needed to be done.
The Dealer will not do any thing if they did not work on the brakes. If the Dealer did this job then you can complain about them.
The black box you are referring to is call ABS control module. It should be on under the hood on the driver side of the radiator. These units do fail.
You can go the the Auto store and ask, if they carry it then they will know where it is locate. You can also go to Dealer parts department, they will carry the part and can show you where it is locate.
If you do replace the control module, make sure the brake line is properly bleed of all air.
I do hope this help you

Hello , the abs code is prob just a maintainence light, prob is fine but GM likes to get you into the shop to have it periodicly checked out. If the abs brakes work and pulsate properly then its fine. The brake light may be a low fluid level in the master cyl reservoir . Clean the cap well and add fluid , the proper type and rating in needed. Fuel pressure sensoe may be due to a weaking fuel pump , weaking pressure regulator or dirty fuel filter. Thank you , Quinn
