Changed front brake pads on my 2000 Jeep Grand Cherokee Limited. Had to remove brake line ''block'' to caliper to remove pad holders in order to install new pads. Can't get brake pedal to build pressure. No obvious leaks anywhere. How do I bleed system? I get some pressure after pumping it, without vehicle running, but as soon as I start it the petal goes to floor
On the inside of wheel is a small bolt that bleeds the brake you my need a extra hand so some one can pump brakes, start from the back then the front, have person who is helping pump brakes a few times then tell to hold pedal down after confirm the pedal is down brake open the bleeder valve then close when fluid shoots out do this Intel feel brake pedal comes up a little after the one move to next bleeder valve. back to front.driverthen, passenger then move to the front and do same. this may help!!!
Something doesn't sound right, you shouldn't have to remove the brake line to install pads. Did you have to do this on both sides? Do the new pads and the old pads look the same? Did you get the caliper on crooked? Just recheck your work first before replacing more parts. When you install the caliper, You have to hook the pad on one side first before you slide it over the rotor.
Well if you have it all back together and everything looks good, Have someone pump the pedal 3 times and hold it. Then open the bleeder, and then shut the bleeder after the fluid comes out. Then have your helper let up on the pedal. Repeat this about 4 times on every wheel you had the line off. Start with the wheel farthest away from the master cylinder, and end with the closest wheel. Make sure there is plenty of fluid in the master cylinder the whole time.

SOURCE: Brake petal goes to floor
if you cant find any leaks in lines or cylinders or calipers u probaly have a bad booster
see lots come threw my shop like that but also their is a vacum line that runs to the booster and it hooks to a plastic valve that goes in to the booster those get gloged and you loose pedal as well try replacing that before you bye a new boooster

Removed it to avoid kinking brake line, I think
Problem was I couldn,t find the caliper bleeders because they were covered with a rubber protective grommet
