Different combinations of braking surface and brake pad can play a part and the conditions can influence the noise your brakes may or may not make. While contamination is one cause, vibration is another and can indicate poorly set-up brakes. The first thing you want to do with rim brakes is to ensure the brake calipers and the braking surfaces of the rim and the brake blocks are thoroughly cleaned and in good working condition.

Bicycle disc brakes squeaking

Disc brakes have become common on modern MTB bikes due to their superior stopping power and modulation. There are basically two types of disc brakes, mechanical and hydraulic, but regardless of which, they both work by squeezing a rotor attached to the wheel hub. Contaminated brake pads are a common culprit behind squeaky bike disc brakes. Various substances can contaminate the pads, such as dirt, oil, or water. These contaminants affect the friction between the pads and the rotor, leading to noise and reduced braking performance. To prevent contamination, it's essential to keep the braking system clean, avoid touching the pads with bare hands while installing and regularly inspect the brake system to help maintain their effectiveness. Another cause of squeaky brakes is glazed brake pads. Glazing occurs when the brake pads become overheated or when they haven't undergone the proper break-in procedure. Signs of glazed brake pads include a shiny appearance and a lack of friction material transfer to the rotor. To address this issue, it's necessary to remove the glazed layer from the pads. This can be done by lightly sanding the surface or replacing the pads if the glazing is severe.

You're gliding down a country lane enjoying the view, peace and solitude when you pull on the brakes and a loud squealing sound shatters the tranquillity. We've all been there — squeaky brakes are near the top of any cyclist's list of annoying bike noises. But it's not just the squeal that's a problem — noisy brakes can also mean decreased braking performance. Squealing brakes can occur for a number of reasons. Often, contamination can give rise to a nasty noise when you hit the anchors — oil or grease on the wheel rim, brake pad or rotor or a misalignment between the braking surfaces can cause a squeal, or perhaps you have new brake pads which may need to bed in. There are a number of steps you can take to reduce the likelihood of noisy brakes and we'll run through these below for both rim and disc brakes. As contamination is a leading cause of squeaky brakes, first check that the rims are oil free and that there's no build-up of dirt — if so scrub them thoroughly with degreaser.
