How much butter is applied to the wheel bearings
is a problem that many card friends want to know. No matter how many or less, the best lubrication and economic benefits will not be achieved. However, what we are talking about today is the relationship between bearing butter and ABS sensor. Too much butter not only affects the best lubrication and wastes, but also causes the failure of the ABS probe.
Although the surface of the ABS sensor probe is almost entirely covered by metal, it is a rather delicate thing when actually used. Due to its position in close proximity to the bearing, it can easily be soiled or even rusted by various dusts and grease in the bearing for a long time. Filling the dirt between the ABS sensor probe and the hub ring gear can affect the magnetic induction detection. Many ABS sensor failure cases are caused by excessive application of bearing grease. Excessive butter can easily be squeezed onto the probe when the wheel is installed. In the light case, the bearing butter is too much to affect the sensitivity of the ABS probe. In the case of heavy bearing grease, the probe can not sense the ring gear and cause the ABS system to malfunction.
Whether it's an axle sensor bracket or a post-weld mounting method, it is very common to apply too much butter. Butter plus dust and metal debris falling from the brake pads are all deposited on the probe surface. The prevention and treatment of this situation is very simple. That is, do not use too much when applying wheel butter to the wheel bearings. When cleaning, just remove the probe from the bracket and clean it thoroughly. Then apply a layer of butter evenly between the probe and the bushing to prevent future rust in the bracket.
