Hi all


Any ideas what may be the cause of this?


Did my first longish run in the 100HP last weekend down to London from Norfolk. It was quite hot and humid and about 20mins into journey I heard this high pitched wittering noise coming from the front.


Initially I thought it was the front N/S brake squealing a bit, possibly due to heat/ expansion/ pad touching disc or something, but then realised that it only happened when the steering wheel was fractionally moved to the right from the central position, or when turning through that point.


So, not certain it was one of the brakes, but the noise was definitely coming from the front end.


Could it be a belt or something to do with the power steering?


Only recently bought the car and its under a 3 month warranty from the garage, who to be fair to them were pretty rigorous in carrying out necessary works to the vehicle before they'd let me pick it up. So, it makes sense to take it back into them to look at, but I just wondered if anybody else has experienced the same thing / has any clue as to what it might be?


Other than that, it was faultless and enjoyed the blast there and back. Averaged 47mpg, which I thought was pretty reasonable.


Cheers

Does the noise alter while applying the brakes ?

Sticky pads in the caliper housings, rubbing disc. Highlighted on turns as disc flexes.

Just needs pads removing and everything cleaning.

Or it might be an intermittent bias feedback from the flux capacitor caused by a loose connection on the conjuvenator loop.

Rare, but it does happen on early 100's.

You need to advise the garage of this fault before it develops further!

Could be the AC compressor if it's low on gas. Switch the CC off and see if it goes away.
PS makes other noises cause it's electrical. If it is sticking calipers (wheelcentres go probably very hot after a while) have it sorted ASAP.

Used to get a "squeak squeak pause squeak" from the front of our 2010 Panda on gentle right bends.
Brakes didn't seem to be the problem, and noise went away after a few weeks so couldn't track it down.
Then it came back after a really wet day.
Turned out it was the brake pad carrier in need of a bit of wire brushing and copperslip.
The pad was catching on some crusty rust but only when some extra grit got washed in.
Wasn't severe enough to generate any noticeable heat or leave marks on the disc though.

You can test the brake caliper with a timber batten and lump hammer. When the noise starts, stop the car then using the timber as drift, whack the calliper. Obviously, don't smash the lights out of it, but enough to loosen the pistons.

If the noise stops you have the solution.

It's either pads sticking in the carrier or the piston(s) are sticking in the calliper itself. That might need a service exchange brake calliper.
