Bangkok: The "Sure Before Sharing" center has verified claims regarding noise issues with motorcycle brakes through an interview with Assistant Professor Nattasit Pattana-im of the Department of Mechanical Engineering at the Faculty of Engineering, Rajamangala University of Technology Thanyaburi.

According to Thai News Agency, several factors contribute to the noise produced by motorcycle brakes. One common issue is a stiff brake piston, which often results from a dirty or rusty lower cylinder, hindering the O-ring from retracting the piston properly. This leads to inadequate clearance between the brake disc and the brake pad, resulting in constant friction.

Another factor is the presence of dust or small stones lodged in the brake pads, especially when driving on dusty or gravel roads. This debris can get trapped between the brake pads and the brake disc, causing noise during wheel movement or braking. Additionally, improperly installed brake pads or worn brake pins in older vehicles can cause the pads to loosen and rub against the brake disc, creating noise.

Warped brake discs, typically due to thinning and exposure to intense heat, also contribute to noise issues. Such discs need replacement as they cannot be repaired. Low-quality brake pads with a hard compound may cause severe friction and occasional squeaking, while a misadjusted brake pedal travel in drum brake systems can lead to constant rubbing of the brake pads against the drum.

Wet brake pads are another source of noise, as moisture reduces friction, causing slippage and noise during braking. This noise typically dissipates once the pads dry from use. Furthermore, nearly worn-out brake pads force the piston to extend further than usual, disrupting the O-ring's ability to retract the piston fully, leading to incorrect pad clearance and resulting friction.

In summary, motorcycle brake noise can arise from multiple causes, and addressing these issues promptly is crucial for safety. Ignoring them could lead to significant problems affecting vehicle safety.
