My break peddal goes all the way to the floor and break fluid is leaking out by the back right tire area why

You have a broken brake line.

Most likely the front brake hoses are worn.

wheel cylinder leaking. need to take to repiar shop for replacement.

Good to hear you got it fixed.

If u have not lost ne brake fluid then its ur master cyclinder under the fluid resevour only two bolts and the brake lines if u r losing fluid wouldnt always c if drum brakes can,leak inside the drum its called a wheel cylinder really depends on if losing fluid?

If the brake master cylinder is full with approved DOT 3 brake fluid and the vacuum line that attaches to the brake booster is in place and not leaking or disconnected at either end, check for leaking fluid on all 4 tires, if you find no fluid at the tires indicating a caliper is leaking then the problem is the master cylinder being bad.

yes, that would be the primary reason why the pedal hits the floor. What color is the smoke. Let us know.

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...;-)

You should be able to look around each tire and see where it is coming from, let me know if any of them have brake fluid on them, if so it is a brake cylinder leaking, if the leak is somewhere else than I may can help you with that, oh and when you do find the problem I can probably save you some money on the repairs.

check for brake fluid you must be losing it some where,did you recently had something done with the brakes you might have air in the lines and have to bleed the system,if you didnt check for leaks looking at the back of the tires to see if thers brakefluid on the tires or on the ground,if this helps please vote me a fix ya
