having some trouble with the brakes on "my" Volvo 855. Seems like the front right brake pad is in constant contact with the disc. At least that's the only explanation I can think of after noticing a horrible grinding noise along with a way too hot brake disc... anyone have any simple solution? I was hoping that performing a series of hard brakes would help, but it didn't. and I don't know how to dismantle the damn thing. and I need the car tomorrow. and I don't have enough money to have someone else fix it...

I know it's not the same car but I had a similar problem recently on my AX mean machine.

In my case the slider in the caliper had seized meaning that the brakes were constantly on...

If that's the problem every time you jam the brakes on to try and 'clear it' you're pressing it further on to stay there and make the problem worse...

daft as it may sound, i used wd40 on my rover when it did this. mechanic couldnt stop it doing it (smoking at lights it was that hot) so i flogged it in the end. wd40 cooled it and stopped the damn squeeking too.

That bloke that sorted mine broke 3 or 4 chisels getting the slider to move again...

get some re con calipers that will stop you for sure!

If you can hear grinding more than likely one or more pads have worn through to metal on metal and you need to have the rotors replaced or turned too. Be very careful stopping till you do this, you won't get as much stopping force as normal. Check for it as soon as you can.

When I change the pads in floating caliper systems I make sure I've cleaned out the parts the pads slide on. They often get quite gummed up with gunk and rust. The brake pads should be able to slide easily on the supports.

i have had a couple of cars like this where the flexy pipe has collapesed inside and is holding pressure
