Annoyed! Seeking advice.

97GT. Replaced the rear brake pads and started getting a squeaking sound. Advised to change the rotors. Bought the AM power stop four corners kit. Replaced all rotors and pads. Rears still squeak. Embarrassing to be driving such a nice sounding car and the brakes squeak. Any suggestions?

Make sure you put brake lube on the hardware , and back of pads where piston compresses.

And before you put rotors and pads on spray them all off with brake cleaner. They are contaminated when they are packaged.

Haha.
DON'T USE GREASE ON THE BACK OF THE PADS.
There's a special product that eliminates disc brake squeal. I can't think of the name at the moment.
Just go down to the local O'Yamamoto auto parts store. They'll know.
Tell them it's for a Subaru, that way they'll help you.

Yeah. Stop squeal. Or something like that.

It's not good practice to use the synthetic brake grease on the brake pads.

For obvious reasons...

You, apparently, know the correct product Slow, why aren't you using it?
The brake squeal is caused by vibration. The "Stop Squeal" provides a much thicker surface to absorb the harmonic vibration.

Where do you work Slow?

Well the saying "stupid looks are free" really apply to this country. These people don't do their own maintenance so no one knows what I'm talking about. Even went to an automotive store "Autobacs" (some of you may know the name) and they kept trying to sell me brake cleaner.

I've worked at Nissan , ford , carmax , now at a engine research company ,

I'm just saying .. We would clean off the contamination on the rotor/hardware.. lube both ends of the brake pad , the hardware, the back where the piston compresses , and the front where the caliper lies on, so we would not get any " comebacks "

And I would rarely get a comeback for brake issues.

You can always resurface your pads ( rough sandpaper/ die grinder with a cookie pad ) , clean off rotor/hardware/pad with brake clean , apply stop squeal to pads .. Wait 15 min , lube up pads and hardware , and whaaaaa laaaa, no more squeel..

The only reason why you hear noise ( squeal ) is because there is vibrations .. The lube helps stop vibration so you don't hear it..

I worked for a while with a good friend of mine who is an ASE mechanic; and he told me the same thing about contamination.

I was suprised to hear a lot of other "mechanics" had no idea about that.

Squeal can also come from the material used in the pad. If you are using metalic or semi metalic, your chances are high for squeal and dust, along with faster wear of the rotors, but great braking.

Ceramic brake pads are composed primarily of ceramic fibers and other filler materials. While ceramic brake pads are usually more expensive than other types of pads, they are cleaner and produce much lower noise levels. Also, they provide for excellent braking and don't cause a lot of wear on the brake rotors.

All 18 brake drums on my Mack truck and trailer squeal. If I float the brake pedal just right when pulling to a stop, it sounds like a church choir tuning up for mass.

Using the Power Stop set which is ceramic pads. I'm not sure if the grease was used but I'm trying to locate some before opening them back up. Someone also mentioned the cold temps could be a factor but I don't recall them doing it last year before I swapped the rotors and pads.

Finally found the grease. Opened all four corners and greased them. Seems to have solved the issue. Thank you all for the input.

Yeah I'm going to do this too when I redo the brakes in the back. PO of my car cut the rotors instead of putting the right caliper brackets on when he did the Cobra conversion and I borked a rotor a few months ago so I'll either include new rotors when I trade this SRA for a IRS or just do new 31 spline axles/31spline rear, the right brackets and rebuild the calipers.

Stupid money pits lol. Also why I tend to always go after bone stock cars instead of modified ones. This car has had a few surprises I have not been happy about but not too bad.

Yeah I bought this car almost bone stock. I changes the pads and rotors and that is when the squealing started. Everyone around me was like its normal for ceramic brake pads to squeal in the winter. I just wouldn't accept that answer. The grease worked wonders. I also cleaned the rotors really good just to be safe.

I actually had a tube of grease (brake pad grease) that I applied to back side of the pads and standard brake cleaner that I wiped the rotors with.

Raybestos rotors, centric pads. get from rockauto. I laugh at ppl who use duralast or wearever crap from the box stores. Napa rotors are garbage too. Have fun with your runout issues.
