I bought a specialised hardrock 2008 series in september of 07, and at most 2 weeks afterwards when ever i went on trails the front brake would screach like hell, as i used it more it’d screech more often. Now the front and back brakes screech when i cycle along a flat road and brake.
Both brakes are avid ball bearing 5’s
can someone please give me some idea of what’s wrong and what to do about it?
thanks

Pads or the braking surface may be contaminated by either oil, WD40, GT85 or something else.

Replace the pads + clean the discs with some solvent then bake them* in the over for 10mins.

*if they’re Hope rotors with flaoting centres, don’t do this.

Uh…in’t it the pads you bake?

FWIW my BB7’s do this from new 🙁

You can bake the pads to remove any contaminant, but I’ve never had it work. Works on the rotor though.
