Brake constantly applied

Hi,

My front brake is constantly applied, making a slight screeching sound. I just bought the bike and the seller told me it's because the brake pads are brand new (which they are) and that it will go away. But I've ridden the bike 40 miles since then and there's no improvement.

Should I just wait some more and do some hard braking or is it a sign that there's something wrong with the calliper?

All help is appreciated.

Are the brakes binding badly?

You may need to clean the pistons if the seller just put the new pads in without giving them a clean.

Most probaly the piston(s) not retracting

My front brake rubs a little when I push the bike, a bit of resistance, but I was told this was normal with all bikes/disc brakes. ?

my front brakes make a sort of scratching noise if i lift the front wheel off the ground and spin it, still gets 4 or 5 rotations before it stops, brake disc is only warm to the touch and still stops well, does it do it while you ride? how loud is it?

I suggest you take the caliper off, remove the pads, move the pistons out and give them a clean (brake cleaner or WD40) dont get WD40 on the discs or pads.

Push the pistons back in and replace pads (if pads are shiney then give then a gentle rub on a paving flag to get the shine off) then reattach the caliper(s).

gonna need to get them apart and clean the surfaces of the piston(s)

Allright, but the bike only has about 700 miles on it, can the pistons really need cleaning? The bike has been stationary in a garage at the police since march '08, could something have dried up or similar?

Check the caliper and make sure you can see a little bit of the pistons poking out. If you can't that might suggest the pads are the wrong ones.

loosen calipers (not too much) apply brakes, retighten calipers.
