The OE pads should have had some kinfd of shim that clips onto the back of the pad. They also nomally have spring clips that insert into small holes on the pab to help keep some tension on them so they dont rattle in the caliper. You can get the hardware kit from Toyota or you may try some of your local parts stores to see if they areavailable aftermarket.

 

What you may need is a small bit of high-temperature grease here and there.

A lot of people think changing the pads is all that is required to service the brakes, but there are many places that need cleaning and lubricating. When I recently did my wife's Gen2 1990 Camry, I cleaned and regreased the slide pins, cleaned all the brake dust off the calipers/housings/pistons (don't breathe the dust though), and put a thin coat of grease on all the contact points where the pads touch/slide/move. I personally also put a thin layer on the back of both pads just to keep things quiet and keep things from seizing/crusting together.

You also want to make sure that all your hardware is good - spring clips, springs that join outer and inner pad (wire that goes into holes on them), etc. etc etc. Resurfacing/replacing the rotors, checking for glazing/hardened pads, checking hoses, and checking the pistons for free movement in and out of the caliper are a few other things to look at.

But after all is said and done - sometimes the things still squeak (a tiny bit) her and there - so as long as I know I have everything maintained and kept an eye on I don't let it worry me.

Good luck and God bless

 

Good post Tracy!

the pads might also need to be broken in. search online for it, i dont know the exact procedure (also depends on the pad material) but new pads squeeking is a problem thereof

 

grease it up behind the calipers and the pads

You can also use spray or spread-on "disc brake quiet" on the backs of the pads. It is a tacky substance that is applied to the back of the pads. Give it about 5 minutes to set up and then reinstall the pads. It keeps the pads from vibrating in the calipers. It's this vibration that usually causes the noise. I haven't have as much luck using the high temperature grease on the backs of the pads. YMMV.

You'll want to make sure to use a synthetic type grease specifically for this purpose. Petroleum based grease will weaken the caliper piston seal.

 

try taking them back and get OE pads from your dealership. I drive for a living, and after a year with AutoZone's finest pads, I got tired of them squeaking too. They'd squeak when the light pressure was applied, but nothing during a hard stop. Maybe the design, maybe the materials, but the Toyota pads haven't squeaked at all.

Oh, and petroleum greases should not be used, as they are temperature sensitive (i.e. flammable), and may cause other problems.

 

camry's doesnt seem to like aftermarket brake pads... only oem ones. I had nice stuff from Kragen on my 98 camry... squeeked like crazy and just bought pads from toyota and never squeeked.

 

I have used Raybestos "full ceramics" on both my 94 and 98 Camrys with noise no and minimal amounts of brake dust. I tried their "semi ceramics" first on one car and got some noise, so I swaped them out for the "full ceramics" and it made quite a difference.

I replaced mine with OEM brake pads on the front and for me, they squeak considerably loud with light pressure and no squeaks with hard pressure. Also, the dust builds up really quick with OEM pads. One thing I'm always not sure about is where exactly to apply the "brake quiet" material; I know we should put it on the back of the pads, how about the back of the metal shims where the piston makes contact?

Compared to the aftermarket, I've got very little dust from the OE pads. I put the anti-sqeal gunk on the back of the pad and then placed the pad on the shim (term?)

 

When I use the "disc brake quiet" spray or goop, I don't bother with the shims. I keep them in my garage just in case I ever go back to Toyota OEM pads. I have never had a problem using just the disc brake quiet without the shims, as long as I stick to the Raybestos full ceramic pads.

What about Rotors, u should replace the rotors if theres squeaking noise.

 

tracy made the best post there. Lube up everything.

When I did my front brakes I kept the shims and put them on the new pads (semi-ceramics from Napa). Also Autozone pads almost always squeak. It's because especially with the cheap ones they meet the rotor at a 90 degree angle. That makes for a lot of vibration. The pads I got are bevelled in to allow for a better angle. That's the way expensive Wagner and OEM pads are... I personally consider brake pads worth the extra money ... i think i spent $30 on my front pads, when I could have gotten them for like $8. I don't feel gyped, they're quiet, they stop really well and they don't get hot very fast.

As for the rotors, any time you replace pads have the rotors machined if they're not too thin. If theyre too thin to machine, get new ones.

 

For the record, I currently have good quality AutoZone brake pads in my '99 and they are silent.

 

5spdV6 is on the right path, it could be rotor related this squeak. No one wants to spend money to replace rotors that still look good - the smoother the better. If they are not smooth, but grooved and wavy, then the rotors need truing or replacing if you want to eliminate the squeak.
If the rotors are still smooth, an important step when putting new pads on old rotors, is to sand the rotors with fine emery clothe. Sand them across and not round and round, like cleaning a CD, and one minute spent on each side of the rotor should be enough. This sanding is to break the "glaze" from the old pads. And then clean them rotors but good with brake cleaner, til a white paper towel stays white. THEN put the new pads.

Also as the other fellows said, if there were pad shims when you took it apart, be sure to use them. Toyota did not go to the trouble of putting them there for no reason. And in addition, you can use the goo that goes on the back of the pads, as well as the shims.

Basically, a pad that is squeaking is one that is vibrating in its caliper. They include the shims and brake goo to prevent this. So i usually make a point of using them.

 

i would just like to add that at least for the gen 4's, aftermarket pads usually squeek...although i am unsure why. it has happend with my car, and will stop with oem pads.

mine is a v6 and using non ceramic pads definately cause it to squeek, even toyota non ceramics. I have Akebono pads on *i heard they were oem basically* and they are excellent. I am inclined to try some Hawk pads as they are higher performance *i read that on tire rack*.

Adding grease may help, it sure hasnt helped me. and ive used shims for each pad too.

 

Shims:
New high-quality pads will frequently come with these pre-installed, you may not need to move over the factory ones. Get good pads! This is one area where I do not buy cheap.

Springs:
As previously noted, there are anti-squeal springs. On my 1997 when I overhauled I just got a new spring kit and replaced these along with others.

Cleaning:
Clean the daylights out of it! All that brake dust caked on won't help matters.

Lube: Generous amounts of brake lube in the right places should solve remaining problems.

I rebuilt a 93 and a 97 recently. Okay I replaced the rotors too. I sleep better knowing I have "fresh brakes" and this stops the squealing from both the car and the lady of the house who has to drive them. A bit expensive but worth it IMHO.
