Asap need help!!!!!!
I just finished my brake pads all around and 1 rear caliper. There is no pressire on the brakes now. The pedal goes right to the floor. We have bled the lines and no air is present. Is there a reset for brakes? Any ideas?

was there a lot of pressure when you bleed each caliper? did you start with the right rear? how were you bleeding them? when did you stop getting pressure on the pedal?

Try turning the key on or letting it run while you bleed. I had a similar problem with a mustang. They have an electrical pump setup for the abs. Who knows, it might work for a jeep.

Bleed starting from the caliper farthest from the ABS block (right rear to left rear to right front to left front). Ensure you DO NOT let the resevior run dry. Once all have been bled start the vehicle and depress the brake approx. 10 times. The repeat. You most likley got air in the ABS block and it will take some effort to get it out.

Try gravity bleeding that caliper, take off the master cylinder cap and open the bleeder on the new caliper for about 3 to 5 minutes, keep a wathc on the brake fluid in the resevoir, dont let it get to low.

If you put a new caliper on it's going to need quite a bit of fluid to fill it up. Were you refilling the master cylinder with fluid as you were bleeding? If not your master cylinder is now probably very low on fluid.
Assuming you are doing everything right, there is the possibility that you got air into the ABS / ESP system. The dealer's procedure is to use the starscan to sequence the pumps I believe.

Gravity bleed the caliper. Back 20 years or so there were a couple of vehicles we had to bleed the master cylinders on by cracking the lines on the side of the cylinder, but this was pre-ABS days.....you are better off to clamp your flex line when replacing a caliper to prevent the fluid level in the upper system from dropping too low and creating a bleeding problem. Fill your master cylinder and if all else fails gravity bleed the whole system, closing each bleeder as fluid appears.
