SOURCE: Changed front brake pads. brake pedal goes to floor. no brakes

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!!!

SOURCE: Brake pedal goes down to floor. Putting brake fluid doesn't solve problem. Vehicle must coast to a complete stop.

First look for obvious leaks under the vehicle, especially the inside area of each wheel... If you see fluid, you have either a blown cylinder seal or a bad line (check the rubber hoses to the front and back brakes too) Repair the offending part and bleed the air out of the system... (remember to clean pads or shoes if they have fluid on them)... If you see no hint of leakage anywhere, then suspect the master cylinder... if you remove the master cylinder, check and make sure that it didn't leak fluid into the brake booster diaphragm (Brake fluid will destroy the booster)... as in any repair when you open the system (lose fluid), you will need to bleed out the air to restore function... hope this helps...;-)

SOURCE: Brake pedal goes to floor. No fluid leaks found.

It needs a master cylinder. The only other thing it could be is if you have an exhaust leak, boiling the brake fluid, but this would happen as you drive it, not just sitting there, without it running

do u have the antilock brake bleeding tool? if not you will need to have the dealer bleed the brakes, the ABS control valve must be electricaly held open to bleed the brakes there of course is a special tool for this.
