Re: air around break petal
It sounds as though the diaphragm on your vacuum assist has ruptured. This will cause a hissing sound and less brake you may also notice a change in the engine idle speed or a rough idle until the hissing stops.

Check to make sure that you put brake grease on the back of the pad where it meets the caliper. Also, for the brake petal slowly sinking, this is most likely caused from air in the brake line. Make sure you bleed the brake lines and check for any possible leaks.
check the switch behind the break petal if it is either needs adjustment or is in need of replacement best way to check is unplug the switch and see if break lights go off or just lift up on the petal.
if you look above the break petal under the dash you will see a little switch attached to the petal. on most cars the switch is adjustable by pulling the pin out of the switch a bit and then putting it back in and pressing the break petal to re calibrate it. if that dosent work it may just be broken and needs replacement. also look around the break petal area under the dash and make sure nothing is keeping the petal from coming all the way back up
You have air in your break lines. The two ways you can solve this problem is have the breaks blead to get the air out of the lines, or you can take the top of the break reservoir and pump your breaks to the floor. DONOT DO THIS With the car moving. What this will do is force the air to the reservoir.
you need to check the break fluid level now i do think it is too late tho what it sounds like is air in your break system you need to bleed the breaks not doing so can damage the break booster you need to add fluid to the booster now as it will help and may not need bleeding if you keep driving the way it is you may loose your breaks all together which is a danger to you and others you need to have this attended asap it is not a hard job or expensive job when you put fluid in the car pump the breaks every time you need to or they get soft this forces the fluid through the pips altho the air may have no where to escape which is why we bleed them to let the air out hope this helps ricko
if you have not fitted brake pads to it [as these can take time to bed in ] and give the pedal a soft and extra travel feeeling you have air in the brake system the simple check to do is look behind all your wheels see if you can see brake fluid sepping down the back plates or any damp patchs which would inply there is a problem if not pick your bonnet up have a look around your master cylinder to see if theres any sign of a leak that was the easy bit if you can,t see anything you will have to take the wheels off to find out what is leaking don,t forget if you change one of the seals or calipers or cylinders on that axle change the other side yates210456
