I know the issue regarding disc brakes has been raised many times before but my 5’s have developed a terrible squeal.
I have checked the disc which doesn’t appear to be warped in anyway.
the pads have also been properly aligned
When i was out yesterday, i resorted to spitting water from my camelback onto the pads every so often to stop the noise. It’s got so bad that I am even considering pouring a load of oil on the pads, may reduce braking but at least i won’t have the annoying squeal!! 😆 😆
I have cleaned the disc and pads with Muc-Off disc brake cleaner, going to run a cotton but between pads to make sure there is no dirt that hasn’t been washed out.
Any ideas on what could be up?? if not think i’ll invest in a decent set of ear plugs!!!!
Just a thought, try doing like we do in the motor trade, take the pads out, clean the friction side with 80 ally oxide paper and coat the back of the pad with copper grease (you can pick this up in small tubes at all good accessory shops as they say) be carefull not to get the grease on the friction side or the disc.
