The car is 1.6 16V. Vauxhall Vectra R reg. I just brought from the garage few weeks ago. I am stopping, but when you step on the pedal and stayed, especially in an inclined position, the pedal will sink to touch the floor. I tried to step on it repeatedly to see if it hardens midway, as all other brake pedal should be, but it wont gets hard. It was already bled, and a cylinder was replaced by the garage owner few days ago, still the problem exists. I am afraid to drive in the motorway for fear tha the brake might lost at high speed. Please Help. Thank you all.

It sounds like the mechanics did a bad job. This is a VERY dangerous fault and you should not drive the car any further than absolutely necessary -- and definitely not on the motorway. Drive it very slowly at the quietest time of the day to the garage and have them fix it under warranty. And take a knowledgeable person with you, to back you up.
Repeat: Stay off the motorway! You either have air in the lines or a leak in a cylinder or the master and in neither case can you do a safe stop from higher speeds.

98% chance it is the master cylinder or air in the lines. Maybe the new master was defective. Bleeding the lines is best done with a pressure bleeder that forces fluid through the master and out the calipers. Less likely, you could have a caliper overheating and be boiling fluid. Most people smell a over heated brake in these cases. In very rare cases a warped rotor can pump air into the caliper by modulating the piston. Bleed them again, my guess is the mechanic missed getting all the air out.

Could be a leak in the hydraulic system.
Could be that brake fluid is extremely low.
Could be the garage ripped you off, since a defective master cylinder is the most probable cause, along with air in the system (which you said have both been addressed).
Don't have any other causes for you!

It sounds like the master cylinder has gone bad.
If you pump the pedal and it gains pressure, it would be air in the system. Pumpt the pedal and no change in pressure would be a faulty wheel or master cylinder assuming the lines are secure. If all else checks out fine, have the pedal adjusted.

the clicking and the goofy pedal behavior is the anti lock brake system functioning. the question is why is it functioning on dry pavement? I would have a shop look at the ABS system. Those explorers specifically had wheel sensors that were prone to damage. If the ABS is functioning when it should not, you are loosing brake effectiveness, and this is a safety issue.

Check the brake fluid! Sounds like you have a leak in something! Very dangerous so get it fixed right away! Call for a tow truck if you need to get it to a shop.

i own a repair shop,and there's only one true thing that will cause that to happen on any car and that's the master cylinder or it hasn't been properly bleed out yet, id take it back to them because its not safe to drive ,and they are responsible for doing it right and id make sure they under stood this time that it needs to be done right ,they shouldn't have ever let it go with out at least checking it really good,but that's what ,causes it,and id take it back you already paid to get good brakes on it,,good luck i hope this help,s.

You have wheel cylinders at each wheel that can leak too, also lines where they meet at each wheel. Check the inside of the tires for any brake fluid leakage. Some mechanics just suck.

Check fluid level...If normal, then it's the master cylinder...If low, fill up, and pump the pedal....then check for leaks. Fix leaks.
Don't go out and change the master cylinder, unless you have eliminated all other options.

Check the fluid and bleed the lines, check the master cylinder isn't leaking and that the top is on tight.
