🔧 Mercedes-AMG C63 S – Brake Noise Diagnosis 🔧
This C63 S came into Mastertouch Automotive after the customer complained of a loud banging noise from the left-hand front following a recent front brake pad replacement elsewhere.
After getting the car on the hoist and inspecting the braking system, we quickly found the cause — the left front brake pad retainer pin bolt was completely missing! 😳
With a high-performance vehicle like the C63 S, correct brake installation and torque procedures are absolutely critical. A loose or missing bolt can allow the brake pads to move under braking, creating a serious safety concern as well as the loud banging noise the customer was experiencing.
A good reminder that when it comes to your brakes, quality workmanship matters.
If your vehicle has developed an unusual noise after repairs or something just doesn’t feel right, get it checked.
