    I’ve recently brought a second hand Cannondale which has been an absolute joy to ride. However, the brakes (normal disc) have started squeeking really badly – especially at low speeds and when comming to a stop.

    I was wondering – do I need to bleed them or clean them and if so, can anyone recommend what type of cleaning products I should be using?

    Thanks guys!

    Could try cleaning the rotors with denatured alcohol, usually works.

    Bleeding is for sponginess of feel and lack of power.

    Squealing is typical of misalignment and contamination.

    For cleaning rotors

    Pads are generally binned if contaminated. You could try roughing them up to see if that helps or throwing water and grit at them and bedding them in again. There is a trick with an oven but can lead to the pads coming off their backing plates just when you need them…

    Hi Tomlevell, thanks for that…first thing in the morning i’ll get some Isopropyl Alcohol from my lbs. As for contamination or misalignment, I dont know how this can be possible because although the bike was second hand – it was pretty obvious that its never been used. I’ll put this question to the people at JeJames (my lbs) and see what they think – might just be a case of running them in?

    I’ll be in touch….thanks again
