Hope rear disc not quite powerful enough?

[Daz N]

Hi,

For a while now I've had hope 4 pot XC discs with standard hope pads. Recently I changed the pads
and had a bit of a struggle, the new rear pads wouldn't fit as they touched the disc, even with the
adjuster wound all the way out. Anyway once the new front ones had worn slightly I put them on the
back and new pads on the front.

Now it seems as though if I'm doing anything more than 10 miles an houe the back brake is working at
about 10% of what it should be. I can't even lock the wheel on gravel!

The front brake is superb, in fact I could lock that everytime if I wanted to.

So why is my back brake so ****? I know brakes are to be used as a pair but if my front failed then
I'd be stuffed!

Thanks in advance

Daz

I'd bet on something with the pads, not anything Hope-specific.

I've got a similar situation with my C2s, but not as bad as 10%...more like 40%. I can make that
comparison because both my FS and hardtail wheelsets have the same Hope hubs and rotors. Only diff
is that the hardtail has Avid mechs and the FS has Hope C2's. I can swap rear wheels between FS and
hardtail and experience the diff. The rear Avid locks up the rear wheel on dry pavement if I apply
them very hard at all. With the Hope there's no way I can lock the rear wheel - but performance is
still good enough, so I haven't sprung for replacement pads yet.... Also, the Avid pads are
sintered-something-or-other and the Hopes are a third-party's "Green" compound...

I heard that if you get any kind of oil on them (including from your hands) it can ruin the pad's
ability to brake...

Try finding fine, stone free wet mud and plastering it all over the rotor. Go fast, brake hard.
Repeat. If you can't find the mud, find dust and make mud.

Best way I've found for bedding in new pads, and cleaning **** off old ones.

Hi,

The hope pads I bought where supposed to be "sintered"... perhaps I should just accept that I need
to use front and rear together!

Thanks

Meaning that I have to accept the fact that the rear doesn't work on it's own, DUH!

Avid mechs, Bill The mind serves properly as a window glass rather than as a reflector, that is, the
mind should give an immediate view instead of an interpretation of the world.
