My front RHS disk brake squeals when light pressure is applied. pads and bearings are not old or worn. It does not make a sound when the brake is steped on with firm pressure. I can not see any signs of metal to metal contact. I removed the pads and flipped them over but the squeal is still there. Whats some reasons for sqeaky brakes?

Focker out.

my brother used grease on his front discs hyundai excel
it stopped squeal. but it the back locked up when braking normally, wonder why
i degreased it, a bit of detergent, hose off.
and brakes return to normal with no squealing.

I am a bit hesitant to put any lub near the disc. I have see that brake squeak stuff at the local part stores. Might go read the label. Its annoying me to the point of turning on the radio loudly to not hear it. I would way rather listen to the engine noise as usual.
Or just spray them down with degreaser?

With most aftermarket pads you dont get the anti-vibration plates that always got replaced with the og disc pad kits. Maybe your plates are dented, not there or aligned with the piston incorrectly. Also a build up of dust or even the caliper seals are damaged and upsetting the way the pad sits on the piston, also what brand of pad, Ate are best IMO.

DONT LUBE THE BRAKE PADS

Those little metal anti vibration plates I have are as old as the hills.I will recheck to see if there in there correctly and go buy some new ones. Cool, I never new what they were for. The calipers are ATE and the pads are Bendix.
I have noticed the fronts do spit out a lot brake dust.

Brad are they single or duel pin pads?

last time i chucked new ones in mine they squealed like a pig and when i checked i'd left out the butterfly clip/retainer thingys that sit between the pins
chucked an old pair in and problem gone

they make the pads out of such soft compound these days so the discs last longer. makes for lots a brake dust
sucky thing when you have thinnly spoked rims that are a pain to clean

Hey Joel. Yep, they are two pin calipers. I am pretty sure I put those clips back in. The brakes did not make a sound for a few months after going through the whole system. But tonight the left side started doing the same thing. I am thinking it is sounding more and more like the pads are the problem. I painted the rims white a few weeks ago so you really notice how much dust these things are spitting out.The disc surface is still pretty good so I think I might try a different brand of pads or throw the old ones back to see if they do the same.

I was watching a car restoration show on Fox and they used a copper grease or something like it to stop the pads from squeeling. Can anyone else shed more light?

Yeah, like Matt said - don't go putting grease or lube near brake rotors.

Braking is all about friction.... grease and lube are specifically designed to remove friction.... so although grease or lube might stop the squeal, it's definitely going to affect how well the brakes work.

well you could try one of those brakleen stuff from repco.
someone here told me to use that when my flywheel came out and soak my clutch in oil.
but i didn't use it since i'd have to go and buy it. what i used was degreaser.
sprayed on brush it. hose off. detergent and brush. left it to dry
and it's back on and i don't have "torque converter" anymore.

but that's a clutch.
you could try clean it first.. before replacing stuffs.. or resort to lube

Hey Matt, Thanks for the explination . That would make sense as the front left started squeeling 2 weeks after the right. I noticed the rhs pad backing was starting to wear through the protective/anti vibration coat.

What other kinds of product can be used on the pad backs besides the copper spray?

alien8,

Can't think of any brand names off the top of my head but most of the stuff auto parts shops sell as anti brake squeal products involve coating the back of the pads.

Make sure you read the labels carefully, as some of them contain some really nasty toxic and or carcinogenic ingredients.


Regards,


Matt.

Fixed! no more squeeks
I pick up this red goo from Supercheap to coat the pad backs.Its like a sticky rubber when it drys.
Thanks for the help all
Brad.

Brad,

Let me know how it goes, out of curiosity (I'm running drums) I would like to hear how long the "red goo" lasts. There's a spray on version of it too, for just a few bucks more.

I was in supercheap today too and saw the copper spray for $30 for the small size tin. I reckon you would get 3 or 4 sets of pads done with that, easy, maybe more. You would only need to build up to a millimetre or so of copper on a new pad.

With the copper spray, given the shortish life of spray cans once they've been used, I would advise (at that price) getting a few sets of pads and doing them all at once or, going halves with a mate and do two or three sets each, then it would work out quite cheap.

A decent spray of copper will usually see a set of pads through to the end of their useful life, that's why I'm interested in hearing how long the "red goo" lasts.

Don't forget, it's time to replace pads when they are under half of their original thickness, unless you are really anal and check them all the time. Most normal people just look at them when they are doing a service or have the front wheels off for some other reason. If you don't get them early you end up with worn discs and sometimes, overheating wheel bearings.



Regards,

Matt.

Thanks for all the advice Matt, I found it really helpful especially if my brakes start to squeel worse than they are now. I couldn't agree more on checking the pad thickness, I don't like the thought of only a milimetre of material protecting my life.

Hey Matt. well, two weeks in and no squeeks yet so I guess the goo's not complete bollocks. I have pressure hosed the calipers a few times since smearing it on and its all good. It called Dynagrip Squeel Free. I saw the copper spray at Supercheap too for $30 and thought it was a little pricey to do one set of pads.The Dynagrip was ten bills and I used stuff all. I would say the bottle would last a long time being a paste in an air tight bottle. You can get little sachet of a similar product from SC for a few bucks too.All good!
