My OSR wheel has an occasional rythmical squeal (a sort of eek eek eek noise), which I only notice at low speeds. This goes away if I apply the brakes, but comes back as soon as I lift off.

Having done some research on old posts:
* The pads should be genuine GM (last changed at a VX dealer).
* The car is not used very much and has been standing.

I'm preparing for a strip down to check pads and calipers, but can I avoid that ?

Thanks.

It really is worth having a good look, if only for your own piece of mind !!
Also you learn a lot

I had those symptoms because my handbrake shoes had worn a groove in the inner drums in the rear discs. Everything worked fine but it was irritating and embarrassing.

I put up with it for 60,000 miles before eventually replacing the rear discs/drums, pads & shoes. That fixed it

Thats funny as i've got almost the opposite symptoms.

My brakes squeal when they are warmed up.

New GM pads & disks 

Any ideas?

Hi there, mine does something similar - usually after a bit of a run, I get an 'eek eek' noise from the offside rear wheel. If I brake, it vanishes, but can come straight back. If U brake hard, it goes away for some time. Is usually present if I'm doing a gentle left turn - but it is coming from the back wheel. Rarely happens at high speed.
Not had chance to get the wheels off and have a good look yet, but I can see the pads and discs look okay. Like Andy H says, it's more irritating & embarrassing than anything else. I've not had the car long so figure it could be down to OEM pads or discs....?

One of the possibilities listed in Haynes is damage caused by a foreign body getting in there.

Could be... I'd have though some grit or something would have worn itself out after a couple of hundred miles though....

Haynes implies that I need to strip the disc and calipers to inspect the drum - is this true, or is there a clever way to do it ?

Thanks.

1. Support the car
2. Remove the wheel
3. Undo the retaining screw that holds the disc onto the hub. Screw one of the wheel bolts in a few turns to keep the bolt holes lining up with the hub.
4. Undo the caliper retaining bolts (can't remember if the shock absorber is in the way for this one, if it is you have to put a jack under the hub to compress the spring slightly when you release the shock absorber bottom mounting.
5. Very carefully ease the caliper off the disc, there should be enough give in the steel brake pipe to allow you to do this and suspend the caliper behind the disc.
6. Using a torch & screwdriver peer through the hole provided in the disc and undo the handbrake adjuster enough to pull the disc off.

And reassembly is the reverse of disassembly. (or whatever the phrase is that Haynes used to use )

That sounds more like it - I just need a few hours without rain. And don't get me started on reassembly is the ..... !

You can always go in one of the holes in the drums with an optical scope that has a 90degree mirror on the end, but stripping and cleaning it, also rubbing the edges of the drums and shoes is always a good thing to do, remember to adjust the shoe tensioner to the lowest setting and you avoid breaking them on the wear edge in the drum,  re-adjust them when you fit it:)
And if the drum is stuck, a good trick is to ram it hard where the bolts go in until you hear and see that its loose;)

it could just be dust, getting well back, wearing a space suit and moving to a different county after. even though theres no asbestos any more. fire high pressure compressed air in said hole. should clear any dust, and may change colour of neighbours washing.

Got the wheel off, but can't undo the caliper, so I've splashed the WD40 around (carefully, obviously) and will leave it to soak.

Turning the hub, there is a definite contact being made by something part of the way round. It was resonating on the backing plate (although that could have been secondary from somewhere else), so I've played with the backing plate and it doesn't seem to be happening any more.

That doesn't really sound like a proper solution (and I'm planning a 250 mile round trip at the weekend), so I'll continue trying to strip it down but if I can't manage that I'll do the necessary 20 miles to see if it starts happening again.

I've got to collect some bits for my Vdub tomorrow, so I've put it all back together and will see how I get on.

it could even be the ratel plate worn out they only plastic. or a sticky gate copper grease just need for them, if dose it when they are hot it could be a bent disc.
