Hello guys, I need help for my 2016 Porsche Macan S. When I brake, I hear squeaking noises and it irritates me hearing that. Does it sound good to replace the brake pads only? or I should also replace the rotors?

Also, I already bought brake pads from R1 concepts and ready to go to a mechanic. I'm just waiting for your advise for approval If should buy a rotor.

Thank you

The rotors needs examined and measured. If smooth and still thick enough you can re use them. I got a pad change out of my rotors. Squeaking is not the warning sign for bad pads in the Porsche. They have a wear indicator and not the squeak bar that the American and Japanese cars use.

What is the mileage on those rotors? If 50K miles, time for new rotors as well. Squeaking is caused by pad build up on the rotors making the pad vibrate in the caliper bracket. New pads on old rotors won't fix noise usually.

Yes, measure the thickness of the rotors to verify but, if the Porsche Macan needs new rotors after only 50,000 miles, then something is either very wrong with the brake system or Porsche is using mild steel for its rotors. My F150 SuperCrew has over 110,000 miles and is still on its original rotors, even after many years of towing a 20 foot race trailer. I just get the impression that Porsche wants to sell folks a lot of overpriced parts.

60k miles -- give or take 10k or so -- is pretty typical for some vehicles, such as for some BMWs when it comes to rotor and pad replacements. Seems that the rears wear out faster, at least from my experience with both X3 and X1 models. Wear and tear will also depend heavily on the driving conditions, such as frequent stop and go city traffic vs. a lot of interstate travel.

NC TRACKRAT

I acknowledge what your experience may be but hard to explain when brake bias is usually 60% or more to the front brakes, not the rears. The fronts do most of the work, not the rears. That's why the front pads and calipers are larger.

NC Trackrat, you should know better! Your F150 doesn't have the same brake aggressiveness as a Porsche SUV. German performance vehicles are designed with more aggressive pads for shorter stops, than in turn causes rotor wear.

Your 993's eat tires about every 20K miles, right? Your F150 about 3x longer or 60K miles. Why? The 20K mile tires have more stick. Same thing with brakes. My Audi SQ5 - which is essentially a Macan S, would need rotors at 50K miles. But it was a city car, not a highway cruiser.

Dr., if I were the average Porsche owner, you would be correct. I don't want to get in a "urinating contest" but you make assumptions that I'm the average Porsche owner who puts the stickiest tires on his car because Porsche says you should and that I drive like most Porsche owners, on the aggressive side and use every stoplight for an excuse to race to the next one. I keep my tires inflated on the high side, pay strict attention to proper alignment and get much higher tire wear than 20,000 miles because I save my aggressive driving for the track. Even then, running four or five events a season, I usually get a full season out of a set of pads and change rotors every other season. Our C2S has just under 50,000 miles and I recently gave it its first brake pad change. The rotors are in excellent shape and are no where near the end of their life. As for the F150's brakes, they have more aggressive pads because I changed them at 65,000 miles due to the work they have to perform. There's nothing more critical than having to haul down a 12,000 lb. load when some stupid driver pulls out right in front of you! You're correct that I know better because I've been working on cars for over 65 years, from normal maintenance to full concours restorations to race prep. I still do all the maintenance on all our vehicles.

There are many factors that will contribute to brake pad and rotor wear. Trying to compare brake wear among different cars and people is similar to trying to compare insurance rates. While one experience maybe the rotors are fine at 50,000 another experience might be they're needed to be replaced at 30,000. I will need to replace my pads and rotors at just over 30,000 this year. My 2018 turbo was a Porsche HQ vehicle that had a lot of brake wear by 2,000 miles. The pads needed to be replaced when I bought the Macan.

Just have everything measured. I measured when I swapped the winter and summer tires and they will need to be replaced.

X2, brake usage really depends a lot on how the vehicle is used (stop-n-go vs highway). Before the Macan S, we had a 2011 Q5 3.2 for 6 years, it would eat the front rotors and pads, Pads would last 30k-32k miles, Front rotors would be 1 mm within spec so I would just replace them at the same time. Rears lasted twice as long.

Ohh that's why it's still noisy. Yes, its above 50K miles and I am planning to buy drilled and slotted from R1 Carbon GEOMET® Series Brake Rotors so It could pair from brake pads. Thank you very much for telling me your experience and expertise. Much appreciated!

jessad26

Thank you for telling me your experience. I will replace my rotors.

Smart! There you go!!! I love to use these opportunities to upgrade. Especially helpful if you are trying to convince your partner that these modifications are necessary maintenance items.

drcollie

why are you putting cheeses grater rotors on a Macan? Like shortened pad life?

MrMarco

Anything to reduce heat on the "S = small" brakes on this tubby beast. I think that was my biggest disappointment in this vehicle, brake fade. In fact after a hard first rally in the Macan S I was close enough to the bumper of the truck in front of me stopped at the light on my exit to smell the skunk he hit last week. Coming from a 911 it was not a surprise but certainly a let down. I am currently looking for a BBK or swap in 5K.
