Brake fluid leaking below driver's side door. Brake pedal to the floor. 2000 Bravada. I will assume that the line is bad and will need to be replaced?

Are you just opening the bleeder and letting it run out? If so have someone pump the brakes and hold the pedal while you open and close the bleeder don't let off the brake pedal until bleeder is closed . Repeat this process until only fluid comes out . You probably have to bleed both sides . Keep an eye on the fluid so the resivor doesn't run out then you'll have start all over.

Is the brake light on? Check your fluid level. Pedal going to the floor could be because of a leak in the hydrolic system line, hoses, caliper, wheel cylinders, master cylinder internal and external leaks. Can also be because of over sized drums and/or under adjusted brake shoes.

Brake lines by rear door on drivers side are a common failure point. lines under door failing can cause a total brake failure. Just replace and bleed the lines.

when you push pedal hard & pedal goes to floor does brake light come on?
assuming brake fluid leval is ok & didnt run empty have you checked for a leak?
pulling all wheels & inspecting brakes,cylinders, calipers,& lines for leaks.
does the pedal pump up & feel ok with engine running?if so there is air in the system
if it does'nt change the way the pedal feels & no leaks are found & brake linings are ok & adjusted
properly than your master cylinder is leaking internally & needs to be replaced

possible leak in brake system. if not then you have a bad master cylinder. have to replace it.

youhave eather a brake line failure or if you have drum brakes in the rear your Brake cylinder might be bad eather way dont drive this car before its been repaired

find the leak first and then make a reply posting and i will tell you what to do,remember that iam on gmt+1 time zone for a reply

there is either a leak in one of the lines or you have air in the brake lines. start by bleeding your brakes lines and checking you fluid. then see if you notice a leak in which case fix it then bleed that line and you should be good. if not then it could be a bad master cylinder that would be the next step. also if you had your rotors cut down below spec then the pedal could go to the floor and not have much stopping power. same could go for very bad pads. but from what you explained it sounds like a leak

you did'nt say why you changed the rf brake hose, but i'm assuming it was leaking, check to make sure the new one is not leaking and there is no other leaks in the system, this includes the other 3 calipers and hoses, the rear hose in between the rear hard line on the frame to the rear hard line on the rear axle. if there is still air in the right side line then the left side would be doing all the work and may cause your abs to kick in on the left side if it is attempting to lock up. this may be the noises you are hearing. if you still have power brakes after you shut the engine off, (you should be able to pump the pedal 3 or 4 times with the engine off before the pedal becomes hard) then the booster is ok. if it has a swooshing sound inside the car, (hard to describe that sound on a keyboard), then you may have a leak in the seal on the brake pedal side of the booster. brake master cylinder sounds like it is bypassing. if it still goes to the floor after you rebleed then replace the master cylinder. if a brake pedal goes all the way to the floor, it is possible to ruin the cylinder and cause it to bypass, this is caused by rust or corrosion, the seals on the plunger are compromised letting brake fluid leak past. any other questions please let me know. thanks
