Brake pad squeal

Hiya , after all the rain we had a week or so ago, my front brake pads are being a right noisey nuance, what is the best remedy for this ?
Discs or rims?
 
If it’s rim brakes, clean the braking surface of the rim with baby wipes, or soap and water / sponge cloth, rub the pads with wet and dry paper, then make sure they are clean and dry, then adjust the pads lateral angle to the rim, so that they are ‘toe in’. If they are discs, clean the rotors with a bit of vinegar / muc off / soap and water, then get the pads out of the callipers, put a bit of copper grease or similar on the back of the pads, make sure none gets on the fronts, or the rotors, pop them back in to the calliper, and use a flat metal object ( large flat head screwdriver or proper pad spreader) to get the pads flat. Then see if they’re still squealing.

Cheers , they are rim brakes, when you say toe in , does that mean the front of the pad is slightly angled toward the rim ?

Like the vinegar option ! Will try the copper grease as well, works on cars ! Also I find a big long hill and cycle as fast as you can and pull the brakes on seems to help with bedding in glazed pads :tongue:

If rain started the squealing, it's just contamination. Normally rain helps with squealing because it speeds up pad wear, and pads naturally wear to a toed-in shape even if you don't fit new ones toed-in.
