After a rainy day riding my bike, i had wiped it down and forgot the rear brake and now it squeals when I try to use it. More like an elephant noise. Help please!

Put some acetone on a rag and wipe the face of the brake pad(the part that meets the wheel rim) to clean it. Or lightly scuff the pad with a piece of sandpaper, don't overdo, just enough to rough up the surface

Thanks for the advice, I had did just that, but with alchohol. After the application, i had blasted all of the liquid off with compressed air. Before that, I had visited my local raleigh shop they had told me that I had needed a new wheel. Just because one nut was loose! That was outrageous! And I had went there 3 days ago and they had said to me that I needed to replace my pads and clean my disc of the disc brake. The world is in dodgy bikes now, except for the DIY sector of course.

Some brake pads have a harder substance when they h=get worn down to make a noise so you know they nee changing.

. Not sure I'd want to use acetone, but a good scuffing should do the job. Squealing/trumpeting is usually caused by glazed pads - sand off the glaze and you're good to go.
