1999 Camry CE noise while braking

Hello.

I have a 1999 Camry CE that's making a noise while I'm braking. The noise sounds like a high-pitched squeal or whine, and it pulsates (the frequency of the pulses seems decrease as the speed of the car decreases).

This only starts happening after the car has been driving for maybe 10 to 20 minutes, but once it starts happening, it's constant while braking.

I've tried a couple of things:

1) I took it to a toyota dealership once, and they could find nothing wrong. When they took it for a test drive, it did not make the sound (murphy's law). They cleaned up the brakes, but that was it.

2) About 2 to 3 weeks later, I took it back to them. It had started making the noise about a day after the first visit, and finally I got tired of it. Again, they took it for a test drive for about 20 minutes, but it didn't make the sound. This time, they replaced the brake pads (though the old ones were still at around 95%). This didn't seem to help

- it's still making the noise.

3) On my way home today, it was making the noise constantly. As soon as I got home, my dad and I took it for a drive for about 45 minutes (he had previously not been able to make it make the noise either). The car was parked in the driveway for no more than 3 or 4 minutes, but when we got in and started driving, the noise was gone. It took about 20 minutes for it to start again. We tried various things, such as stopping while turning left, stopping while turning right, and stopping while going straight. It made the noise all 3 times. We tried stopping with no brakes at all (i.e. putting it in neutral and gliding to a stop). The noise didn't happen. We then tried stopping (going straight), and then backing up the approximate length of a driveway. This seemed to get rid of the noise for about 5 minutes, but then it started again.

The thing is, although the noise happens only when I'm braking, I'm not entirely convinced it's being caused by the brakes. My dad seems to think it might be a bearing or an axle or something that's maybe not well-lubricated.

Anyone have any ideas?

Thanks.

Is the noise from the front axle area? You have rear drums on this car right? And those drums are always quiet? These Aisin calipers seem to have problems with noises.

In my case I use Akebono ProAct ceramics pads. Even without the noise shims they are quiet. Pins and contact points lubed with Permatex synthetic disc lube. One original Toyota Aisin caliper seized on me, so I'm running two NAPA premium rebuilts in the front with Raybestos Raymod $20 rotors. Quiiieeeet.

Maybe I should add Aisin calipers to the list of junk parts.

I've been there, obsessing over vehicle noises. I obsess over a bunch of things. It's a no-win game. Now, much older and wiser, if the noise doesn't affect drivability and I cannot determine the cause (squealing belt or something), I let it go, turn up the radio, stop beating myself up over it. Phantom noises are a battle you'll never win. Just...let it go. Forgive the noise, just like Peter Parker forgave the Sandman in Spiderman

  1. Have a great one.
