Righteo, got an Orange 5 (2005 ed.) off ebay about a month ago, but brakes (hope mono minis) front and rear were full of crap and not ridable – despite what seller claimed!
Anyway, I did learn a great deal about hydraulic disc brakes as I’ve never had any before – I got pistons out front a rear, cleaned it all up, put em back and bled brakes. Front one is awsome – it alone is as powerful as my old V-brakes.
Rear one just sucks – just can’t stop me at all.
I think rotor is very, very slightly warped, because it rubs a bit once every revolution, but when I look side onto the wheel it’s barely noticable.
I have put new pads on the front brake becuase they were quite worn, but I haven’t on the rear – but the pads at the moment look like they’ve got loads of life left in them. I’ve ordered some new ones so I will be trying a pad replacement when they arrive (should be tomorrow).
Basically – what would be causing such a loss of power? I’ve played with shims to try and line up caliper better, and it only rubs that little bit where disc is warped and doesn’t look like its flexing the disc when I brake.
It does squeal if I hit the lever hard, and when I press the lever there’s a kind of metallic *ting* sound that I don’t get on the front brakes.
Please help 🙂

P.S. If I was going to replace the rotor, are all rotors the same? Becuase Hope’s seem to be about a fiver more than avids.
