Spongy Juicy 5`s

As a quick recap to previous posts, after a year of riding on Hayes Stroker Rydes I went back to my Juicies as I was a bit sick of the on/off action of the Hayes.
I went from 1 extreme to the other :- the juicies (only the rear) wer biting virtually with the lever near to the bar and seemed to lack power from what I remembered. I tried playing with resetting caliper, pistons etc and eventually bit the bullet, got a bleed kit and bled the brake. THis seemed to make a slight improvement but now it was hard to lock up the brake so I suspected contaminated pads. I bought some new pads and after bedding them in they seemed ok - but again in normal (non-downhill) use I`ve got to get the lever to within an inch/inch & a 1/2 before they fully `bite`.
Last night I rebled the rear for the 3rd time and seemed to pull a lot of air out of the system which after bleeding so recently I wasnt really expecting. Took on a short ride and sure enough pulling the rear brake to a skid at the same close to the bars point.
The front brake, which has never been bled and has older pads in, still bites a good 3" from the bar.
The reach adjust on both brakes is identical
I`ve left the brake lever cable tied to the bar overnight to see if this makes any difference bgut am ready to go back to the Strokers and bin the Avids.
It could be my bleed procedure but I have followed the instructions to the letter using the recommended kit, could I be doing something to influence where the bite-point is inadvertantly ?

could be anything from the bleed to duff seals to poor caliper adjustment.
Or you just need to move the lever further away until things get right."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Bleed the brake again, but this time remove the caliper from the frame and make sure the bleed port/banjo is at the highest point.
If you followthe Avid bleed manual and pressurise the caliper end with the lever syringe locked off, you'll get pretty much all of the air out of the caliper porting.
Then put the bleed port screw back in and pressurise the lever end and suck the air out, and repeat. Once you've got rid of the air from the MC, pull the lever to the bite point, and bleed the MC again, You should get the last bits of air out of the system, then replace the bleed screw. Replace the caliper onto the bike, align it, and test ride.It's nice to be important, but it's more important to be nice.0 -
My juicy 3's are exactly the same. front is excelent, rear is terrible... had them bled numerous times by my LBS with no difference.
they always stay hard for maybe 1 ride if i'm lucky, then its back to the bars. i had them serviced and they found no leaks, so i have no idea whats wrong with them...completly put me off avid brakes thats for sure0 -

Sorry but i would put money on it being a poor bleed. as long as everything else is OK."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

the number of times i have seen shops incorrectly bleed avid brakes is a laugh.
It is so simple but they still get it wrong.
Buy the kit read the manual and enjoy.
First make sure that the disc is not being moved by the pads."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

you have 2?
nice typo.
leave them they will sort them selves out as you use them unless it is a bit worse than a brush.."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

ive had similar problems with my juicy's
bought a bleed kit, used shed loads of dot 4 ( sod using 5.1 ) got all the air out and now they are nice.0 -

I`m using 5.1 - what difference does that make to the bleeding process ?0 -
none, dot 5.1 is better because it has a higher boiling point.
but for general use dot 4 is more than good enough. Ive given mine a good workout on serveral occasions and not suffered any problems.
Price wise i got half a litre of mintex dot 4 for 4 quid and the 5.1 stuff was over 15 quid0 -
Maybe it's just me but it seems like the 5.1 is easier to bleed out in the juicy's. is a shedload more expensive though...0

i think its just you! :P0

a mate of mine has juicys and bought a bleed kit and we followed the book doing it 5 times! its close to good but still no cigar? they wont lock up, so he gave up and took it to a bike shop. still soft as butter and recently my dads bike which is the same age has developed the same proplem with the rear juicy...... :shock:
i just dont get it its just appauling, my bike with its cheap tektro auriga brake has never suffered these proplems.
why do juicys employ this complicated expensive bleeb system......is there any problems with a bleeb nipple? :?Carrera........ cheap stuf is fun!0 -
Mine were a bit annoying - freed a stickly piston, bled them and they work flawlessly now.
Oh and I found Superstar pads better than the OEM ones too.0
