Hope mono-mini problems?

Hi there.

I just got a hope mono-mini fitted to my forks, to replace
an Avid V-brake. I've retained the Avid V at the rear (and thank God!)

The Hope at the front appears to do very little apart from generate
a kind of hissing/scraping noise. The bike slows gradually, but this
appears to be a step back from the V's I had at the front, where
I could pull an endo with only moderate presure on the front lever.

Will things improve, as the Hope pads "bed in" (whatever *that* is),
or have I wasted my cash?

Best,

Vic.

Vic,

this is not normal disc brake behaviour: i run a mini up front and mini
mono on the rear, and they **** on any v-brake i have ever had.
After about 20-30 flat out stops (speed up - stop repeat), ur pads
should be pretty much bedded in, but performance should improve as they
really settle in a bit more.
The brakes shouldn't rub on the rotor when not engaged, and the only
time there should be a lack of power is if there is air in ur system
(they will go spongy and lose power). Or there is a fault in the
brakes production. Plus also make sure u haven't oiled ur rotors or
pads, by accident or through sillyness
If you fitted them yourself, bleed the system, if this doesn't work its
time to go to ur LBS. If ur LBS fitted them, take them back (and kill
them )(all)#
They shouldn't be like that, get um sorted

Cheers
Steve

The brakes are pretty much brand new, so I'll try a few "emergency
stops" to give the pads a chance to settle in before I start
assassinating the crew at the LBS that fitted them!

The pads don't rub at all: I was just disconcerted by the lack of
power from the get-go. Maybe a sequence of *hard* stop-starts will
get the damn things performing as expected. If not I'll go bitch at
the LBS rather than AMB.

Many thanks for your advice, btw Steve.

Have you read the instruction manual? It should tell you that you need to
give the brakes a short period of time, and a bit of hard braking before
the brakes 'bed in'. This isn't just bike brakes, it's the same for cars,
motorbikes, etc.

At the moment you've got an uneven surface and a small amount of braking
surface. As you brake a few times, the surface will even out and conform
to the disc. You'll then have have a large braking surface and very
powerful brakes. You'll notice the difference, especially in the wet.

Instruction manual?

I got a phone call from the guys at the lbs about an hour
after I got the bike home. They "meant" to give me the manual
along with all the old parts off my bike, but when I told 'em
to toss the parts in the spares bin they got confused(!) and
forgot to give me the manual. It should be arriving by mail RSN.

Thanks for the explaination. I'm a little more reassured now.

I had a similar experience after bleeding my front brake (it was a little
spongy compared to the rear) and getting brake fluid on the pads. Nothing
kills pads better than a little brake fluid!
It was like riding with ABS...

So, replace the pads, clean the disk and try again.

Honestly, if they're working right, they should throw you over the bars with
a two finger pull...

Also try smearing the rotor liberally with fine, silty wet mud before doing
the braking hard thing - old hands at this will all tell you the same - it's
the best way to bed them in.
