Don't buy cheap brake pads!!!

I bought some brake pads from a local auto parts store and installed them in my driveway on my 86.5 supra the other day. The front pads were $12 and the rears were $10. The parts store said that they were the only ones that they carried so I just went with them. Well, the things squeak pretty bad. It's really annoying, I had heard about cheap brakes squeaking but i just thought that it was a bunch of baloney cause I've never heard brand new brakes squeak before. Well, I learned the hard way. I almost makes me want to go out and buy new brakes and reinstall them but it wasn't actually me who installed them, it was my dad because I've got a torn rotator cuff and can't turn the wrenches myself. If it weren't for that, I'd definitely go out and buy new ones and do the whole job over again. It's that annoying. So learn from my mistake and don't do the same.

One thing though, I didn't have the rotors resurfaced. Does anyone know if that might have an effect on the squeaking? The rotors did look really good though.

Go purchase SS7231AX pads from NAPA or MX336 Thermo Quiet from O Reily. Turn the rotors and enjoy the quiet pads. The first step to quiet braking is turning the rotors. Cheap pads are known for their excessive noise, dust and fast wear.

Can't it be the sliders (?) that squeak?
I had the same problem with my cheap pads, but eventually after like 3x :D openening the calipers and cleaning the sliders plus the calipers from rust (pads do have to have room to move...) I managed to kinda stop the squeak. I didn't have rotor dust shields then too of course...
So I kinda don't wan belive that the pads are bad.

I did ALL the anti-squeak and backing and such... but in a similar RUSH once, grabbed the "all we have" pads at a local Auto store on a Sunday and did the switch on all four corners. (Rotors were "okay"...) NO squeak, but the pads SUCKED! BLACK DUST in 10 miles (even after break-in) and it WOULDN'T COME OFF with even GOOD cleaners! DOH!

They also felt like cream-cheese after a couple decels, and faded like jeans in bleach! No more cheap pads for crisp!:icon_evil

this is probably not the smartest thing to do, but in my other car, i had squeaky pads and what I did (and its up to you) is spray a little bit of wd40 on the pads and rotors, just a lil bit tho. then go for a drive keeping in mind that you just oiled your brakes. hit them a few times and they will burn off most of the wd40 but should stop squeaking. i know, its a hillbilly fix, but hey, it worked for me.

Don't recommend this fix, it's not very bright adding a lubricant to your brake pad or disc for that matter.
:nono:


Hey,
I dont recommend it either, as i stated, but it does work and as long as you spray them, then get in right away and burn it off you will be fine. BUT if your retarded and oil them, then go to bed and your wife or kid takes the car in the am and doesnt know what you did to it.... then it will be dangerous. like i said, its a hillbilly fix.::dunce::

Problem being the brake pads are quite porous and will soak up any oily residue and will probably be there for quite some time reducing your braking capacity to some extent.

Think Jdub could chime in on this one and let us know whats actually in wd 40and any issues regarding useing it as a form of anti-sqeal.

WD40 is a mix of mineral spirits, light lubricating oil, and naphtha with carbon dioxide as a propellant. Personally I would not use it on brake pads, but it is light enough to burn off quickly...it's the time before it burns off I have a problem with. There are much better products to prevent brake squeal.

I have used it on brake rotors that I store to prevent rust...it does very well in that regard. I also use a solvent to remove it before I install the rotor ;)

I've heard "rumors" that there is "fish oil" in WD-40... like a "secret ingredient" that is natural and has effective properties. Any knowledge if that is myth?;)

LOL...maybe some hexane ;)
The mineral oil in WD40 is only listed as a "light lubricating oil"...who knows, maybe it's the fish.

Don't be fooled to think that squeeling mean bad pads.

My Hawk HP+'s squeel like a raped whore on both my mk4 and my mk3.

I'm surprised no one mentioned the anti-squeal springs.

I put new brembo rotors and porterfield pads all the way around on my car. The anti-squeal springs were long lost. After about 1500 miles, the pads started squeeking. I put up with it for a year. When I replaced my calipers last winter, I put the anti-squeal springs back on the fronts. No squeeking at all now! Perhaps replacing the calipers fixed it, but alot of people use porterfields, and alot of people complain about the noise.

I got the anti-squeal springs at either autozone or advanced. It was part of a bag of goodies called a brake kit for the supra. I think it was $15 for the bag.

Personally, I'm going with OEM toyota pads next time. I drove a sup that had them, and the brakes worked well and there wasn't as much dust.

Yup. Porterfield's R4 also squeal like an old bus and make clouds of black dust, but boy do they stop! They get much quieter over a few months, but are rarely silent. I get some good looks when they're squealing; people probably are expecting to see a bus and instead see a small-ish car.

Similarly, my Wilwood's squeal a LITTLE at times right as I come to a slow stop. Drives me nuts, but I KNOW they are fantastic at what they do... so heck with it.;)

I recall making a "chamfer" on the edges of pads years ago for motorcycles, as the part that causes such squeak CAN be the small area of contact RIGHT AT the corner edge to the little "curb" on the rotor where the wear edge begins. By putting a little chamfer on the pad, it provides a relief so it doesn't contact there, and ends the squealing.


It would depend on what is causing your squealing, though.
