Hope Mono Disc Brake Setup

[zoster]

Hi there!

Today i installed my brand new 2008 Hope Mono disc brake on the rear of my 24".

After spending a lot of time testing around with the different washers, i managed to make the caliper sit almost perfectly centered on the rotor.

Next, according to the instructions it came with, i slowly pressed the lever. The pads moved inward pretty much at the same rate but one of them hit the disk just a bit sooner than the other one, so (as the instructions said), i tried to keep the rotor in place until the other one hit the rotor as well.

When i released the lever, the inward pad retracted so that it disappeared in the caliper body, but the outer one pretty much stood in place and kept tension on the rotor.

i pressed the lever again a few times while keeping the rotor steady, but nothing changed. It seems the pads don't want the disc to be centered on the caliper, so i rearranged the caliper so that the disc sits equally distanced from the two pads, but this way the caliper is really off center with the disc. The disc almost touches the body of the caliper.

Also, the pads don't retract much, the are really close to the disc (less than 1mm each), and the disc which is just a a little untrue, touches the pads slightly.

Have i done something wrong in the process? Is there a way to improve the situation?

Help would be greatly appreciated!

thanks for reading!

using a tyre lever; push the pistons back into the caliper body, then pull the lever...repeat until they move back freely with the pads inserted

Hey Andrei,

This is perfectly normal and there is always very very little brake pad movement on disc brakes too

What you need to do is:

Using some tissue paper to stop your fingers from touching the rotor (and therefore contaminating it), pull the rotor across against the pad which is out the furthest, making it retract a little.

Pull the brake a few times - you will see the other piston move out.

Then let go of the rotor and pull the brake a few times, repeat the above steps (can be done to either pad) until the rotor sits in the middle of the pads.

You may have to do this a few times throughout the bedding in process of the brake, but once it is settled you won't need to touch it again.

Cheers

hey, thanks for all your replys!

unfortunately i didn't got the chance to adjust it, 'cause i just smashed the lever on the rail of a quarterpipe and now i got to rebuild the lever and most probably rebleed the brake (damn these complicated hydraulic brakes). the lever was hit outwards, or otherwise said, away from the handlebar ,and the piston thingie was pulled out (not all the way, but still, it didn't return to it's normal position).
