Intermittent squealing?

[M-J]

Last trip out an intermittent squeal was coming from the direction of the passenger side rear wheel when driving (I think). It comes and goes, normally starting 20 mins or so into a journey. It goes for a while when tapping the brakes or under normal breaking and also seems to stop when going round a left bend!

I had the brakes checked and all that was found was my front pads were starting to delaminate and all the brakes were very dusty. They put new front pads in and cleaned everything else up.

Problem solved I thought but then on our weekend trip it started again, same symptoms from the same area.

Any ideas or has anyone solved a similar issue?

Hand brake cable adjustment,

I don't know the exact details but my mechanic at the time (a couple of years ago) told me that many people adjust the cable incorrectly, apparently there is an easy way and then the correct way which takes more time and effort.

You have to examine the discs closely looking for signs of heating the disc surface will have a blue tinge. This will find the culprit like caliper piston sticking

Does the noise stop when a, you lightly press brake pedal, or b, you gently pull the hand brake. That may help your diagnosis. For me it was one of the pads in the rear callipers not sliding in the carrier. Strip clean, and fit new pads. You may not need the pads, but for me, if stripping, I’m replacing as I can‘t be bothered to revisit.

Yes it stops with either.

It’s odd that it stops with either as the two systems are separate, well they are on my fiat. The foot brake is hydraulic and applies pads to the disc, and the handbrake is a pair of shoes inside the centre of the disc, using this as the brake drum, controlled via cables.

By steering left you are taking weight off the offending wheel which makes me think wheel bearing.

I think at that age they would have had a different handbrake system but worth looking into for a similar fault.

Some reversing sensors squeal.

Going back to the garage to have the rear brakes stripped cleaned and checked or replaced including the handbrake bits next week, thank you for all the comments/advice.

We've previously had a really awful squeal from the front brakes on our Ducato, both forwards and backwards.
The discs and pads were all in good condition and operating properly. The culprit turned out to be the 'Pad Clips' slightly moving sideways and making contact with the very outer edge of the discs. They are only thin metal clips but they made a hell of a racket. Cleaned up and re-seated, nice and quiet again.
