New to Disc Brakes?
Posted by Valerie on Nov 07, 2017 | General
Disc brake have made a big boom in the cycling industry, transitioning for being a mountain bike feature to an option on almost all other bike categories. While the perks can be big (i.e. better stopping power and control) improper maintenance can lead to unbearable noise and diminished stopping results. Here's the scoop on keeping your disc brakes quiet and performing at their best.
New disc brake bike, new pads and/or a new rotor? Don't forget to break them in!
New brake pads and rotors should undergo a bed-in process before you start riding. This bed-in process does three things to prep your brakes for proper performance:
1. Rids the pads and rotor of superficial oil, grime or other contaminates that inhibit friction.
2. Shapes the pads allowing the maximum amount of surface area from the brake pad to contact the rotor.
3. Transfers some of the brake pad material onto the rotor which increases grip upon future contacts.
Here is an article from Bike Radar explaining the steps to bed-in your brakes:
Other Maintenance Tips:
The number one cause of disc brake noise is contaminants, cleaning your pads and rotors are a good first step.
Never use oils or lubricants near your brakes. It is best to avoid using spray lubricants if you have disc brake pads.
If grease or oil has contaminated your pads sanding down your pads surface may help, though if the contaminant has soaked into your pads they may need to be replaced.
Another possible cause is misalignment of your rotor in your brake caliper or due to a slight bend in the rotor. Rotors can be trued and brakes can be adjusted to allow proper spacing between the pads and the rotor.
