Question: What Happens When Your Brakes Are Wet?

Is it normal for brakes to make noise wet?

When water gets on the rotors, as is likely in the rain, snow or carwash (even a damp fog), it reacts with the steel and creates a thin layer of rust.

This thin layer of rust is not as smooth as the steel rotor, so when the brake pad makes contact with this thin layer of rust, it makes a squeaking sound..

As soon as you start to drive off, the noise is the rusted rotors and metal pads grinding off the rust. This is normal for most vehicles.

Can rain affect brakes?

Long term rain will also effect the performance of the braking system in such as that the water will obviously slow the response of the braking systems, when wet the water act as a lubricant not allowing the brake pads to bite the rotors as effectively as they would if the brakes were dry.
