BRAKING
Riding in bad weather isn't exactly comfortable. If on top of that a part on your bike breaks, your ride can be quickly cut short.
To avoid these unpleasantries, it's a good idea to carefully check your bike. Here are a few things to check:
▪️ Brakes
Your bike's brakes are critical to your safety, and should be checked without fail. How you check your bike will depend on the components that you have installed.
▪️ Bike brakes
In a brake system that uses rubber pads, the rubber wears down quickly in wet weather. Make sure that your brake pads are not too worn down! There is a wear indicator on the brake pads to make it easy for you to tell when it's time to replace them.
▪️ Disc brakes
If your bike has disc brakes, clean all of the brake components, and remove any grease if necessary.
If the pads or discs are worn down or damaged, go ahead and replace them.
⚠️ Important: brake parts don't like lubricants! If they do come into contact with grease or a lubricant by accident, immediately clean the discs, pads, and/or rims.
To clean a disc brake that is dirty or has grease or lubricant on it, wipe it down with a clean cloth, then apply a degreasing product such as acetone or rubbing alcohol.
As for the disc brake pads, they can be irreversibly damaged if they are greased. You can try to immediately soak them in acetone, and let the degreaser act before drying them, and rubbing them with emory cloth or sandpaper.
But the safest is to go ahead and replace the brake pads.
