Does it pull to one side or the other when rolling? If so, then you may have a stuck caliper. If not, then you likely have a bad master cylinder and need to replace. If it is a stuck caliper, it would be wisest to replace BOTH calipers. If the brake pedal feels hard when you push, that would be another indicator the master cylinder is bad - but you may not have the hardness in the pedal. If pulling up on the pedal relieves the problem, I would suspect the master cylinder first. Driving on it could damage many components, and replacing them all may be expensive - I recommend verifying the master cylinder is bad and replacement before driving!!

Testimonial: "Good points. The car is straight when rolling and when under braking. Equally no harshness or jerky braking. I will check out the master cyclinder. Thanks."

SOURCE: 2006 fiat grande punto road/suspension & brake noise

If two different mechanics, including a fiat dealer, already put their hands on your car, there is not much that I can say.
This kind of noise are often caused by bad rotor discs or locking up brake pads, I assume that this had been previously checked and fixed .
about the steering rack problem, when the steering rack has troubles the noise is from the steering rack itself and from the front of the car, if you are sure the noise is from wheel check brakes, or, if the noise does not cohincide with braking, check the wheel bearings.
See here on common brake noises, cause and identifying them.
about "fiat would not allow any more work on this problem", that sounds a bit like rubbish, call Fiat in your country (put Fiat in google, then find support/ contact), and ask them about their policies. I do not think from description this has got to do with steering, unless you get the noise only when steering, nyou usually get also vibrations on steering wheel in this case.


If this had been useful do not forget to rate the solution appropriately.

Many thanks

The engine surges on my 2007 when i step on the brake


If its only when you press the brakes, there may be a vacuum loss in the power brake system. Check the hoses from the manifold to the master cylinder booster or the connection on the booster itself. The hose may be split or the connection loose and leaking air. The booster itself may have a ruptured diaphragm. To check this, start the engine and run for a few minutes. Press the brake pedal and hold in. Turn off the engine. You should feel the brake pedal drop slightly. Remove your foot off the pedal and press the brake pedal a few times. Each time you press it , the pedal should keep dropping slightly and feel harder and harder to press. This will let you know that the booster is working properly.

Can bad 02 sensors cause the engine to vibrate and make a humming noise? or bad motor mounts


Bad O2 sensors affect the fuel/air mixture. Vibrations can be caused by many sources, hard to diagnose here. To test the motor mounts. apply the parking brake, open the hood. Put the car in drive and step on the brake with one foot while applying full throttle with the gas pedal. Watch for excessive engine lifting on one side. Be careful not to have the engine fan to contact the shroud. Now do the same in reverse. If the engine lifts excessively, your mounts are shot. If the engine stays put with only a slight movement from torque, then the mounts are good.

Brake pedal goes to floor


for the pedal to go to the floor there is still air in the brake system. Start again starting from the longest line bleeding each in turn to the shortest line . make sure you have adjusted up the rear brakes before bleeding as every time you press on the pedal the shoes expand right out and when you take your foot off the pedal the shoes go all the way back in. adjust them manually and do not rely on the self adjuster as it only adjusts on wheel movement

Would a failing vacuum booster effect the brake lights?...It seems when the pressure builds back up they work. When it drops they go on for a second then go out.... ALSO would a failing booster cause a...


The booster uses vacumn to assist your foot pressure. A leaky seal or diaphragm in the booster or a bad hose from the engine to the booster will cause the pedal to drop as it loses power assist. I think the brake light switch is mounted under the dash by the brake pedal. Fix the booster now, it may save your life.

How do you turn off the break lights when vehicle is off


Under the dash below the steering wheel and above the brake pedal there is a switch. When you depress the brake pedal the switch is activated and the brake lights are lit. It sounds like the switch has loosened and needs to be slightly adjusted and retightened. The switch is held in place by a single screw and nut. This is also the adjusting point for the switch. If you push upward on the brake pedal the lights will probably go out. That slight movement will show you what a small adjustment is most likely needed to correct your problem.
