My brakes on my fiat punto make a squealing noise when the car has run for about half an hour, i put the brakes on it stops seem to think its them sticking, it even stops when i turn right

stop at an auto parts. they will show you where the power steering oil goes.

This could be violation of State law to sell vehicle with known brake problems, would check with law enforcement. Otherwise sounds like some kind of electrical problem and sounds very unsafe. What if you are going down road at 50 mph and it shifts into reverse?

they dont call them fix it again tommorow cars for nothing (fiat) they are all the same steer clear of anything italian or french all the same rubbish i have constantley having to fix my two neighbours fiats from rattles steering problems windscreen wipers failing radiators failing light flickering i dont think there is an originall part left on it buy german but make it and old mercedes no sensors to fall apart simple mechanics and go on for years without problems thanks ivan

Have it put on a car lift and take a look for loose parts or touching exhaust pipes.

It's the belt tensioner, don't listen to muppets

Definitely change your oil every 3 months or 3000 miles. After you change it add a half cup of Lucas engine oil suppliment when the engine is hot.
If if goes away you know it's cam or lifter issue. If it doesn't the ticking you hear may simply be your fuel system.

your engine turns clockwise and sounds like your timing is out.

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
