Brake "pump up" survey - Ducati.ms

GHEZZI · Jan 20th, 2009, 9:03 pm

To get a better idea of who is effected and remedies tried/success etc, could you all compile the following information by "Quote"
(The symptoms are, squeeze brake lever for a set amount of travel & retardation, release and squeeze again for much less travel and much increased braking power/retardation. Air in system not the problem).

MODEL: (Hyper or 1098, Base or 'S')

BRAKES: (Radial or Radial Monobloc)

PARTS REPLACED: (Standard or aftermarket)

MODIFICATIONS: (Machining etc of either standard or aftermarket brake parts)

SUCCESS/FAILURE:

MODEL: Hyper 'S'

BRAKES: Radial Monobloc

PARTS REPLACED: Discs & m/c replaced under warranty with 1098 pads

MODIFICATIONS: None

SUCCESS/FAILURE: Problem still exists, always feels good for the first ride after bleeding/service/warranty work but after that it returns. ????

MODEL: Hyper 'S'

BRAKES: Radial Monobloc

PARTS REPLACED: None

MODIFICATIONS: Pazzo lever (not really a factor) ... I've bled it a couple of times, but it really doesn't make a difference

SUCCESS/FAILURE: I've just learned to live with it, but I still don't like it. Some day I'll try a different master cylinder...

MODEL: S

BRAKES: Radial Monobloc

PARTS REPLACED: pazzo levers & 999 style reserviors

MODIFICATIONS: only the above

SUCCESS/FAILURE: brakes still pump up. I dont notice it when riding, only when it is parked in the garage.
it seems to me that the pistons are back out too far into the caliper...

MODEL: Base

BRAKES: Radial

PARTS REPLACED: None

MODIFICATIONS: None

SUCCESS/FAILURE: I'm just dealing with the pump up. It's not all that bothersome to me at this point... but it is there even on the base model.

My HM-S does this too.

Must be my management background

OK here's my info:

MODEL: HM-S

BRAKES: Radial Monobloc

PARTS REPLACED: Pazzo shorty lever

MODIFICATIONS: No brake mods - stock pads

SUCCESS/FAILURE: I've gotten used to it but will replace the MC eventually with the trick Brembo unit. Just need to use a little caution when getting back on the HM after riding my other bikes.

MODEL: Hyper 'S'

BRAKES: Radial Monobloc

PARTS REPLACED: None

MODIFICATIONS: None. I've bled it and tried the zip tie around the brake lever trick and let it sit overnight. The zip tie method works for a while but the pump up comes back over time.

SUCCESS/FAILURE: I will probably try an aftermarket Brembo m/c in the future.

MongoWERA · Jan 21st, 2009, 2:21 pm

MODEL: Hyper 'S'

BRAKES: Radial Monobloc

PARTS REPLACED: None

MODIFICATIONS: None.

SUCCESS/FAILURE: It does it like most if not all of the others. Some day I'll care enough to call Yoyodyne and see what Fred thinks it could be. Or I won't. I've gotten in the habit of a qucik squeeze then letting off (with the monoblocs that's not a lot of throw on the lever anyway) before really braking. It takes less time to do than it took to read that sentence by a long shot.
