me and my mate are just looking at a hayes 9. It pumps up well, and grips, but then when released it then needs pumping again to make it grip.
It's as if the caliper/system just isn't holding any pressure. Anyone had any experience of this and if so can you recommend a fix?
Needs bleeding! Only reason that it will behave like that is air in the line probably at the lever end of things. Just beware that you can easily overfill the system so that some none OEM brake pads will drag on the rotor due to extra depth of backing plates. Is the little plastic bleed plug on the lever still there/pushed all the way home?
Remeber to bleed from the caliper end to the lever not the other way round!
it may need bleeding but there is another option which i've had with my hayes.
i managed to kink the hose through routing it the wrong way. the kink did not break the outer skin nor did i see any fluid leaking out. what it did do was break the inner core where the fluid runs, the fluid then ran out into the webbing which sits between the two. the only way to sort it was to replace the hose.
new hose and bleed kit was about 35 quid and at the time crc were doing a whole new brake for the same price!
good luck
A friend of mine has suffered this. Even picked up a brand new brake set cheap from crc and with a few rides it was doing the same. Bleeding it through is only ever a short term fix.
