Squeaky disc brakes are pretty annoying. If you have a squeak, squeal or beeping sound coming from your break, it is mostly a caliper alignment issue or a bent rotor which causes your brake pads to rub while cyling.
There are a few things which you can do, to fix this noise. If you are unaccustomed with bike repair, have the assignment of the brake amended by a Carqon dealer.
1. Bended disc brake
First, you can check if the disc isn't slightly bended. Gently turn the wheel and watch the brake disc move. A curved disc develops an annoying 'beep' due to resonance. If bended, you can try to aim the disk a bit with a truing fork. This tool makes it easy to bend the disc back into shape. A (clean) adjustable spanner can be used instead. Sometimes it’s easier to straighten the rotor by hand, particularly if a large section is bent.
2. A rubbing disc brake
Sometimes it happens that brakes are rubbing. The first thing you want to check is if the caliper is aligned with the rotor of the brake. Loosen the bolts of the calliper so you can move it from side to side. Rotate the wheel and slightly change the position of the caliper until it no longer rubs, or only rubs at one point of the rotor.
3. Greased disc brakes
A third option is to check if the brake disc is greasy. You can clean the brake disc on both sides with special brake cleaner. Brake cleaner is available at most Carqon dealers.
Note: Always check whether your brakes are working, before riding your Carqon.
