The brakes on a Porsche may squeak because the brake pads are not properly seated on the brake rotors.
The brake pads need to be in close contact with the rotors to provide optimal braking performance.
If there is too much space between the brake pads and the rotor air can get trapped and cause a squealing noise.
Another possible reason for brake squeaking is that the calipers are not adjusted correctly.
The calipers attach to the brake pads and squeeze them against the rotors to create friction.
If they are not properly adjusted they can cause a squealing noise when you apply pressure to the brakes.
How to fix sqeaky Porsche brakes?
The first step is to try and determine where the noise is coming from. Sometimes it’s easy to tell but other times it can be a bit more difficult.
The easiest way to do this is by taking the car for a test drive and listening for the sound while you’re driving.
If you can’t determine where the sound is coming from then you’ll need to take the car in to a mechanic and have them take a look at it.
They’ll be able to tell you exactly what’s causing the noise and how it can be fixed.
How do I stop my Porsche brakes from squeaking?
Squeaky brakes are usually the result of brake dust and oils that have built up on the brake pads and rotor.
Cleaning and lubricating the brake parts should fix the problem.
First Park your Porsche on a level surface and apply the parking brake.
Open the hood and remove the engine cover. Locate the brake fluid reservoir and remove its cap. Make sure to have a container ready to catch any spilled fluid.
Using a wrench loosen the bleeder screw on each caliper until braking fluid begins to flow out of the screw (about 1/4 turn).
Keep an eye on the fluid level in the reservoir; if it falls below minimum or starts to rise too high close off the bleeder’s screws.
Have someone press the brake pedal to the floor while you watch the calipers.
When the pedal is released the calipers will retract and the brake fluid will flow back into the reservoir.
If there’s no fluid flowing out of the bleeder screw loosen it a bit more.
Once the fluid is flowing consistently from all four bleeders close them off and tighten the screws.
Replace the reservoir cap and engine cover.
Start your Porsche and test drive it to make sure the brakes are now squeak-free.
If you’re still experiencing brake squeaking after performing these steps then there may be something else causing the noise.
Take your Porsche to a mechanic for further inspection.
Why do my brakes squeak when I brake?
There are a few reasons why brake pads can squeak.
One reason is that the brake pad has gotten too hot and the metal of the brake pad has started to oxidize (or rust).
When this happens it can create a gritty feeling and/or a squeaking noise.
Another common reason for brake pads to squeak is that they’re not getting enough lubrication.
This can happen if there’s too much dust or dirt on the brakes if there’s not enough grease on the rotor or if there’s something caught in between the brake pad and rotor.
Finally it’s also possible that your brakes just need to be adjusted.
If the pads are too close to the rotor they can start to squeak.
Similarly if there’s too much space between the brake pad and rotor air can get trapped and cause a squealing noise.
