[Carbon749]

Fitted the underslung set up myself.

First gripe was the hose was too short. Once that was sorted I sat the caliper on the top of the disk to bleed it. Took a clear plastic pipe from the bleed nipple in to a small jar of brake fluid. Method that worked for was :
1 - undoe bleed nipple
2 - depress brake pedal and hold down
3 - close bleed nipple
4 - release brake lever
5 - repeat 1 to 4 with regular top up of the reservoir.

By doing this it ensures the fluid and air is pumped out of the caliper and not drawn back in to the caliper when brake pedal is pressed up and down.

Carbon, did you switch the bleed nipple and hose round to allow shorter line ?

Yep, either I ran the hose the wrong route or something like that. When I measured it against the standard hose it was exactly the same length.

I know that others on here have also had a problem with the hose supplied with the kit.

After reading other posts on the supplied hose being too short I was a bit concerned when I noted that my hose was not very much longer than the standard one but after inspecting the supplied parts that came with the caliper I found that the hose had to be routed up the exhaust side of the frame rather than the brake side.Once this was done the hose was ok.

I have attached a picture of the routing.The hose looks near the exhaust but is no where near it.

All i would say is when /if the pipe was a bit longer you could of routed the pipe on the outside of the rear hugger away from the tyre, just to give a bigger safety margin.

piccie of my route

Andy, your hose seems to have a different fitting on the master cylinder to the one I got, I was initially going to route the hose near the gearchange side as per original but the 90deg fitting that came with the new hose hit the frame meaning that it had to be routed the exhaust side of the frame.

I was going to route the hose like yours but found that if I used the original rubber hose clip on the inside of the swinging arm and a tie wrap either on the hugger or the caliper bracket the hose was miles away from the wheel/disc/tyre so I just left it as standard.

Got some more bits arriving this week and another set of Diablo Corsa 3s even though I said that I would not spend any more !!! Addictive or what ?

Its only money.......................

[999TREV]

has anyone tried to get the ducati rear stand under the swingarm after installing one of these brkts on an early 999

[andyb]

I use a 998 side entry stand anyway, and allways did even with the old swing arm! The 999 later bobbin type stand still fits..........
