Sounds like you still don't have all the air out, did you start at the furthest from master cyl. This is how its done, RR LR RF LF. just keep bleeding, what your doing is chasing the air, if it broke on the maine line going to the rear, thats wear you want to concentrate your efforts. If you do this for a while and still get no break, it maybe master cyl. is bad and has to be replaced. There might be a lot of air depending on how long it was driven after the line broke and if master was empty and all it was doing is sucking air into system.

Try gravity bleeding.... use a length of small dia hose (like fishtank air hose... you can strech it over bleeders by warming up the end in hot water) place the other end in a glass jar with some brake fluid in it...keep the hose end submerged in fluid.
Begin with the master cylinder. with hose connected and jar lower than the cylinder, open the bleeder, lightly depress pedal to get fluid running. allow it to run till no air is present. Repeat at second master bleeder, then r/r wheel, l/r wheel,r/f wheel and finally l/f wheel.Make sure the jar is lower than the item you are bleeding, make sure that you keep the master full during the entire time you are working, make sure you 'top off' master when finished. If you still have no pedal after this and see no seepage anywhere, your master cyl has been damaged and needs to be replaced.

Hi, Depending on where the leak was it probably allowed air into the brake lines, so you need to bleed the brakes at each wheel. Do it one at a time, and you may have to pump the brakes several times if your leak was at the front to get the air out all the way to the back. Best of luck to you!

1994 Jeep Grand Cherokee brake pedal goes all the way to the floor. Recently replaced calipers and master cylinder and bled the whole system. Brake pedal goes all the way to the floor when first pushed...


Not bleed properly
or you have a rusted out line (leak)

There is NO Procedure-- that when driving a
vehicle or bleeding brakes,do you ever pump them

Brake pedal goes to floor


for the pedal to go to the floor there is still air in the brake system. Start again starting from the longest line bleeding each in turn to the shortest line . make sure you have adjusted up the rear brakes before bleeding as every time you press on the pedal the shoes expand right out and when you take your foot off the pedal the shoes go all the way back in. adjust them manually and do not rely on the self adjuster as it only adjusts on wheel movement

Brake pedal goes to floor on first depression; then pumps up fine


Try this,apply the emergency before stepping on the brake.
If this helps the pedal,the rear brakes are out of adjustment.

Pedal goes to floor, brakeing minimal. Checked pads/shoes, replaced master cylinder, bled brakes same problem exists.


Somehow air isstill getting into your brake lines, please put more fluid into brake resiviour and have another person check the lines while you are pumping the brake pedal, This should really help

Replace brakes. now they go to the floor. bled air


When you fixed the brakes, did you take the lid off the master cylinder. I just wonder if you spilled out your brake fluid. The only reason the pedal should go to the floor is if the brake fluid is gone or the master cylinder is not working. Check the fuse. Check the brake fluid level. The pedal only goes to the floor if there is no back pressure in the lines between the master cylinder the lines to the brake pistion on the calipers. Please give me a good ratin and keep me informed.

the brakes need to be bled to get any and all air out of the line... if you can get an actuall pedal by pumping them... there is air in the line, or the line is bad... try getting the brakes bled first... then if that doesn't help have a mechanic check out the lines and the master cylinder.
