Is it necessary to apply brake guide pin lubricant?
2 Answers
Brake guide pin lubricant is necessary to apply, and it is essential to use specialized grease, otherwise it is prone to attract dust. Below are specific introductions regarding the manifestations of abnormal noises from brake guide pins: Brake pad issues: Problems with brake pads account for a significant proportion of brake noise causes. When brake pads wear down to their limit, a sharp metallic friction sound occurs. For safety reasons, brake pads should be replaced when their thickness is less than 1/3 of new brake pads. Uneven brake pad wear: Severe uneven wear can easily lead to brake noise. Some brake pads may also produce noise during braking due to material reasons. Reaching service life: When brake discs wear to a certain extent, shaking and noise during braking will occur. The most common issue with brake disc wear is the formation of deep grooves. When the surface of the brake disc is obstructed by these grooves to a certain extent, brake noise, vibration, and other fault phenomena will appear.
In my years of driving experience, brake guide pin lubricant is absolutely essential to apply, as it prevents brake system sticking and wear. During my last maintenance, the technician told me that lubricating the guide pins ensures smooth sliding of the brake pads, avoiding abnormal noises or uneven braking issues. Without lubricant, the guide pins can easily rust or seize, leading to reduced braking performance and even shortening the lifespan of the brake pads. I once experienced a situation where I neglected lubrication, and the brakes started squeaking. Upon inspection, the guide pins were found to be stuck, costing me a significant amount in repairs. Besides this, it's also important to use specialized high-temperature lubricants, such as silicone-based ones, because regular grease can melt and fail. I recommend checking this every two years or when replacing brake pads. If you're comfortable doing it yourself, it's a simple task, but if unsure, it's best to visit a professional shop. Regular maintenance of this small detail can save you both hassle and money.
