SUV breaks have been an issue, ever since the 2022 May inspection, in which Rotors and Pads were replaced. Just the fronts were replaced.

The brakes started sqeaking at first, and then the car started to shake mildly when breaking. This eventually got worse.

The car was taken to the shop sometime around September, and the Rotors were sanded down. This fixed the issue for about a month.

The brakes being squeaking again. The car was taken to the shop again, but they didn’t hear it when taking it for a test drive.

Car started shaking again.

I didn’t bring it up during the May inspection in 23. The Rotors were then replaced around June of 23.

The car has started to squeak again when breaking, but only at around 50 mph or above.

    ‘SUV’ are big cars. Most are pushing 2 tonnes or more, so will naturally wear brakes out faster. That goes for all unsprung components such as tyres, bushings, and all the other wear items in the suspension.

    Some cars are notorious for being under braked for their size, especially ‘SUVs’ that share platforms with standard sized counterparts so that contributes to it as well.

    That said, brakes shouldn’t judder/shake under braking during normal operation, even when worn. Juddering is due to something either not being right or very, very heavily and dangerously worn brakes. It may be warped disks/rotors (from cooking them due to overuse), pitting (if the car hasn’t been driven much) or something else. The squeaking can be anything from debris caught between the pad and disk, a hard point on the pad or the wear indicator (called a squealer). The former 2 generally clear themselves out.

    Without knowing how and where you drive or perhaps even the car itself it’s difficult to say where the problem lies. A set of pads and disks can easily last 10s of 1000s of miles. But it depends on many factors.
