For the last 2 weeks, my breaks have been slack. I needed to push very hard to break. Today I took the car and suddenly I couldn't break anymore. I checked the break fluid and there is plenty of it. The disks, hoses and gallipers have been changed a month ago so they must not be at fault. Do you any have clues as for why my car does not break anymore?
My car does not break anymore! Why?
If it barely works (brakes), it has to be a vacuum line. Trace all vacuum lines off the brake booster. I gurantee one is loose or has a small break in the hose.
Do not assume that the mechanic put the %26quot;new%26quot; hoses on correctly. This is a simple 15 minute job to trace hoses. In fact if the mechanic did install new hoses, you won't even get greased up doing so. If the hoses are not new, I suggest you call your mechanic and complain he is a liar.
In addition, you sure your mechanic actually bled your brakes? Probably not the issue as the brakes would be VERY soft.
Best wishes.

you were very foolish to not go back to the mechanic immediately. Tow it back now. He could have done something wrong.
If its hard to apply the pedal to stop it would be your brake booster.They are applied by vacuum so i would check to make sure that the hoses are connected.Other than that look into getting a new one.The brake booster is what multiplies your braking effort to stop.Another possiblity is since you replaced those parts, if you bled the brake system of air properly.This would give you a spongy pedal feeling and harder to stop.GL
only things left that effect all 4 brakes is the master cylinder, and the brake booster, and the line splitter, my money is on the master cylinder, as you did not mention a whooshing sound in the days preeceding, the brake splitter can block off all 4 wheels but is EXTREAMLY rare, but the seals in the master cylinder can start coming apart then a piece jam up in the cylinder, best way to tell is take the 2 nuts off the master cylinder holding it to the booster behind it, it's not nesessary to disconnect the brake lines, there is plenty of slack, pull it forward until it comes off the studs, press on the brake pedal and the rod inside the booster should move outwards easily, if it does then hold the master cylinder and using a screwdriver push in on the back of the cylinder at the center, it should move inwards, with a bit of oomph. If you need help changing either one e-mail me and I'll walk you through it.
could be your master cylinder but don't assume that disk hoses or calipers are not to blame it all depends on who you had do them actually im pretty sure it is and you just got sold some stuff you didnt need here is a site thawt could help

try checking out the master cylinder
so what happens when you hit the BRAKE pedal? does it sink in? it could be that your line from the CALIPERS need to be bled. let me know.
To test your master cylinder you need to (with the car turned OFF)pump up your breaks by stepping on the break pedal several times. Then leave your foot on the pedal and start your car if the pedal sinks to the floor it's most likely your master cylinder.
