Pista breaks squeaking

On my Speciale, I switched to the Pagid RSL1 pad and leaned into the noise. The OEM ones would sometimes be quite and sometimes be ultra annoying. RSL1 pads improve the braking feel and only make noise at ultra low speeds. Your mileage may vary.

 

I was told that these brakes need to be driven where they were disigned for ...

Then it may go away ... or get new pads and drive harder from the beginning

 

Brakes.

 

Drive harder, brake harder. Rinse and repeat.

You say you tried bedding in your brakes. Describe what you did please. Most people do not bed in brakes properly.

 

Sorry to be “that guy” but you May want to change your auto correct. It’s brake.

 

Can we get the mod to edit the title.. it just kills me.. I’m that guy too

 

But ... is your problem solved now ?

 

In my Pista,I had a slight rattle upon braking at 800 miles. It was determined by service that the rear emergency brake pads were loose. Once torqued to spec never had an issue. You might check if they are torqued correctly.

 

Sorry, I call BS on this.

Sounds like you read this on some internet forum and regurgitated it here.

You got up 100 mph? 7 times? Where were you? I hope not on some public road.

Then you got the car up to 130 mph? 5 times? WTF?

Then you braked as "hard as u can"? No, you should not brake as hard as you can but brake hard enough but so hard as to activate ABS. Did you trigger ABS when you stopped from 130 mph down to 30 mph? Do you even know what ABS feels like?

And then you drove for 30 minutes without stopping? At all? That's really hard to do. No stops for 30 minutes ... where were you? In the middle of some deserted oval Nascar track?

Here's a primer from the Brembo site:

HOW TO BED BRAKES EFFECTIVELY
Properly bedding brakes is crucial for achieving optimal performance. Follow these step-by-step instructions to ensure an effective brake bedding process:

• Find a Safe Location — Start by locating a safe and open area where you can safely perform the bedding process. Choose a straight stretch of road with minimal traffic or a designated testing area.

• Warm-up Phase — Before beginning the bedding process, warm up your brakes by driving at a moderate speed (around 30-40 mph) and applying the brakes gently to generate some heat. This step helps prepare the brake components for the bedding process.

• Acceleration and Braking — Once the brakes are warmed up, accelerate the vehicle to a moderate speed (around 50-60 mph). Apply the brakes firmly but gradually, slowing the vehicle, but not stopping. Think 10 mph. If you stop, the hot pad will leave an imprint on the even hotter rotor, potentially causing disc thickness variation down to road. Avoid harsh braking where the ABS kicks in.

• Repeat the Process — Repeat the acceleration and braking process several times, allowing a few minutes for the brakes to cool down between each cycle. Aim for around 8–10 cycles to ensure proper bedding.

• Cool-Down Phase — After completing the bedding cycles, drive for an extended period without heavy braking to allow the brakes to cool down gradually. This step is essential to prevent excessive heat buildup.

• Visual Inspection — Once the brakes have cooled down, visually inspect them for any signs of irregular wear, glazing, or other abnormalities. Ensure that the brake pads have evenly deposited material on the rotor surface.

Try it again and get back us.

 

Technically, it's 74mph (for the 458):

You know something went down when the boss shows up in a brake squeaking thread.

 

I’d rather the thread title was corrected. If you ever misspell brakes in a car forum you should be banned

 

Is this car new to you? Do you know what pad compounds you have? Race pads squeal like hell when cold. And some continue to squeal when hot.

If you recently acquired the car I recommend investigating the pads first. And switch to a street compound if someone else installed more aggressive pads that don’t suit your use case or needs.

 

Change the pads and bed them properly (not the kamikaze way proposed above). Get up to about 70-80 and drag the brake at about half pressure down to about 30. Do that about a dozen times and you'll be good. Do not wait a long time between cycles. That is wrong. Do not wait more than like 15-20 seconds. You want them to heat up and transfer the material from the pad to the rotor. The way you'll know they're bedded is you'll smell them. Then do a visual inspection to confirm. After the brakes are bedded and you've confirmed this, there is no need to drive gingerly. Go at it!

 

you mean break squeaking thread.

 

Your just breaking enough to insure you're breaks are beded and stop squeeling.

 

That’s perfect! Teachers everywhere just felt a disturbance in the force with that sentence.
