Pulsating Break Pedal
Guys, just of late, my break pedal has started Pulsating on light breaking. It's like a judder. Doesn't look serious but beeps odd. It's intermittent. Doesn't happen all the time.
anyone have any experience with this occurring? I have a C63S AMG 2019

All fixable. Or, there could be nothing wrong at all and you are just experiencing normal juddering after driving the car in the rain, or the car has been sitting for a bit and the surface rust on the rotors has been scraped off and has temporarily glazed up the brake pads.
Good luck.

Uneven pad deposits is the most common cause of pulsation in the brakes. How is the car being driven mostly? If the rotors and pads still have enough life on them, go for a proper bedding of the brakes. Most brake issues stem from lack of proper use. Need to get this baby boiling once in a while and do some hard braking.

Check the tire wear. There may be some odd wear pattern that happens at specific speeds. How many miles on the tires, what brand tire? Did you have an alignment done when these tires were mounted?

Thanks for the reply guys. My wife mainly drives Miss Daisy so the car doesn't get thrashed often. I give it every now and then but nothing resembling a thrashing.
seems very light under the foot and you can definitely hear in the passenger seat. So it's loud but soft if I can explain a little better. Weird.

If so and based on what you are saying, you likely have glazed pads or as I said uneven pad deposits. That's just what happens if you don't get heat into the performance brakes regularly, and/or bed them in. How many miles does the car have, and have you checked how much pad is left? It could also be that the brake pads are about worn. Don't know what to expect with Miss Daisy driving, but I needed new pads around 18k miles.
