Brake noise!

[bobombo]

Is the supra brake supposed to make noise like crazy when easing in the brake? It's worst when first driven and wet. Thanks.

How much mileage? Check pads and rotors?

Yup normal. Performance brakes make noise.

Only 2000 miles. At first I thought it might need breaking in period but it's 2000 miles now and the noise is not any better. You can hear it from the end of the street.

I haven't checked the pads but the rotors look fine. Could the pads and rotors be glazed or something from the dealership?

I don't know! It's embarrassingly loud. I had mustang pp1 with Brembo 6 piston and it did not make a sound.

I'm not sure. Speaking from my own experience I have not had any loud brake noises with mine. With past vehicles most brake noise was pad related but I don't think that would normally be an issue at 2k.

Hmm that might not be right. Mine squeal a little as I come to a stop. Definitely not as loud as you're describing.

When I step slightly on the brake, like easing into it, it makes the loudest noise. Also It's the loudest when the car's been sitting there for while and especially after the rain. It's funny when I'm leaving places. They stared and then cringed lol!

When I first picked up the car from the dealership I noticed the rotors were worn in unevenly. It looked like somebody at the dealership took it out for a fun drive and hard braking. I might have to take it back to the dealership for them to look at.

Nah I just get a little squeak as I come to a stop.
You might have pad deposits on your rotors. Go on a quiet road, and accelerate up to 70, and brake hard to about 10. DO NOT STOP. Do this about 3 or 4 times in succession. Then drive around normally for 10 minutes or so, see if it still does it.

Mine squeaks a little, but only when the car is not warm. I have about 600 miles.

When I got my car the brakes did squeak like you are describing for the first few hundred miles along with that new brake pad break in burning smell. But I'd say it was gone with in the first week of driving.

Did a few hard braking and yeah I think this helps. It's not super quiet but it definitely helps.

I think I've been braking too lightly. This car is supposed too be driven hard and brake hard lol

Kind of the typical wet brakes/corrosion experienced by brembo pads (and others performance pads). Sounds almost like a whining horn. If you crank your steering left/right at a standstill while holding your brakes you might be able to replicate those noises too. I live in a foggy/humid climate in SF and almost all of our cars (economy, trucks, EVs etc.) all exhibit this. Pretty prevalent are the brembos that are equipped on the Corvette, two Teslas, and my Supra on my block. None of us can escape the neighborhood in silence...not even the EVs lol.

I have a 2020 with 2300 miles on it now, I bought it a month and a half ago with 1400 miles on it and I have the same exact issue as you! It makes the same noises as you described when I first drive it for the first few miles each day or if it's rained or gotten wet. It makes a car horn sound as you are easing to a stop and it's annoying and embarrassing on a fairly new car.
