Hardtailrider Posted February 8, 2011 Posted February 8, 2011 Hi All I'm trying to bleed my Juicy 5 rear brake for the first time, using the proprietary Avid bleed kit. Removed brake pads/clip from caliper, put bleed block into caliper to hold pistons back, and connected the two syringes to caliper and lever as specified in the instructions. Supposedly, you should be able to just squeeze DOT 5.1 fluid through the caliper, via the hose and lever, into the upper syringe. Problem is that the fluid will not shift. No matter how hard I press the caliper syringe's plunger, no fluid movement happens. Have tried pulling on the lever syringe's plunger while while pressing on the caliper syringe's plunger as well. Both plungers slid easily before connecting to the brakes so the problem's not caused by seized plungers. Has anyone had this problem and/or have a solution? Help/suggestions much appreciated!!!
Bike Mob Posted February 8, 2011 Posted February 8, 2011 I bled mine with the reservoir open and pumped fluid from top through to the bottom into a waste bottle. Roll the bladder over a full resevior to complete
Bike Mob Posted February 8, 2011 Posted February 8, 2011 Maybe the bladder is in the way on the top? causing a lock?
Pomstar Posted February 8, 2011 Posted February 8, 2011 Rather go from the brake lever to the calliper.... your problem... have you loosend the callipers oil input/output bolt. I think it uses a size 8 spanner.....

Avid instructions and instructions elsewhere don't mention needing to do that but certainly something else to try. Thanks for the suggestion!

Thanks again to Tarmac & Pornstar - problem solved. I screwed the lever reach-adjustment grubscrew out about 20 clicks and the fluid shifted without sweat :-) Help/suggestions much appreciated!!!
amasendeinja Posted February 8, 2011 Posted February 8, 2011 At the risk of being lambasted for asking the obvious - have you loosened the hose clamps on the syringes?

Only silly question is the one not asked - yes, the hose clamps were loose :-) Solved the problem by slacking off the lever reach-adjustment grubscrew. Tx for responding!
