What Causes the Clicking and Shaking During Hard Braking?

[McSteven]

Generally speaking, the reasons for clicking and shaking during hard braking are as follows: 1. Sharp screeching sound when braking: When a new car produces a sharp screeching sound during braking, many car owners assume it must be a quality issue with the vehicle. However, this is not necessarily the case. New brake pads and rotors require a break-in period. When braking, if the pads happen to grind against a hard spot (due to the material of the brake pads), this noise can occur, which is completely normal. 2. Dull thudding sound when braking: This situation is often caused by a malfunctioning brake caliper. Issues such as worn slide pins or detached spring plates can prevent the caliper from functioning properly. 3. Hissing or squealing sound when braking: This type of noise is harder to diagnose, as it could stem from various issues with the caliper, brake disc, or brake pads. If the noise persists, the first step is to check for a dragging brake. A caliper that fails to retract properly can cause prolonged friction between the disc and pad, leading to abnormal noises under certain conditions.
