Assuming you have rim brakes you need to toe-in the blocks. This has been covered previously and this is a good description:
You can achieve this by inserting pieces of cardboard to the rear of the block (in the V shaped gaps above), applying the brakes and simultaneously tightening the blocks.
See this:
So the pads need to be closer to the rim at the end of the pads that is nearest the front of the bike.
As you pull on the brakes, the rim tries to drag the brake pad along with it, and this twists it (about an axis coming out of the screen, as you look at this diagram). This brings the rest of the pad into contact with the rim.

Yup - the piece of card that the new brake blocks are usually shrink-wrapped onto is actually a part of the 'fitting kit'!!

Buy "Koolstop" pads. Problem solved!

kool stop salmon is said to be very good
ensure the rim braking surface is clean and the rubber contact braking surface of all pads are clean and filed flat

Leave them squeaky so pedestrians and taxis can hear you coming
Only kidding, the above suggestions work fine.

I have this problem and I think I know what caused it in my case. I think I got a bit of overspray of WD 40 onto the discs when cleaning my bike.vthey never used to squeal before this. Is it possible that has happend to yours?
I wonder if there is any thing one can do clean if off? Meths? Anyone know?

Assuming the same approach as with a motorbike, copperslip all contact points between the back of the pad mounting plate and the caliper.
