We just replace the calipers on our 02 Chevy Trailblazer. Now we need to bleed the brakes, but it isn't workin

Question

What can we do?

Answer 1

Gravity bleed the brakes.

1- open master cyl and make sure it is full

2- open bleeder s***w at right rear and let it flow until clean brake fluid comes out.

3- do same on left rear

4- do same on right front

5- do same on left front

Just make sure master cyl stays full at all times.

Answer 2

when you open up the master cylinder to fill up the brake fluid do you remove the black rubber piece inside? Made that mistake once. Also try gravity bleeding the system. It's easy and there is no pumping involved. All you do is keep the Master cylinder filled and open up the valves and let them drip for a minute close them up and your done. It's easiest way to bleed a brake system.

Answer 3

those chevys are hard headed at times if the front end is higher than the rear...the master cylinder sits slightly up in front....i have put stuff like a 4x4 under the rear tires and THEN bled them....try raising the rear end a little...good luck

Answer 4

what isn't working?

more details please.

Answer 5

You've bleed the brakes and the pedals still soft? I believe you can actually put the calipers on the wrong side on that veh. Is the bleeder on the top or bottom? They need to be on the top. Good luck.
