reteid Posted December 30, 2011 Posted December 30, 2011 i have avid juicy five's.yesterday i lost the metal thingy that as far as i know keeps the pads from not rattling.it is on the brake funny shape normally put it in last when replacing the pads.now i have a ride this afternoon and no shop has them avaiable.can i go and ride my mtb this afternoon without this or would this create problems?
divernick Posted December 30, 2011 Posted December 30, 2011 Are you refering to the spring that separates the pads inside the caliper? I would be afraid that the pads would constantly rub on the disc...
reteid Posted December 30, 2011 Author Posted December 30, 2011 @divernick thanks for the reply,but no.it is the one that sits on the outside.
rad006 Posted December 30, 2011 Posted December 30, 2011 Is it the one to stop the pin from sliding out? As then if the pin has a thread. Go and ride your bike. A hobby shop will have body pins that will fit there I think
reteid Posted December 30, 2011 Author Posted December 30, 2011 @rad006 thanx for reply but the fives does not have a pin so i am not sure as to what this part that is missing actualy do.
Capricorn Posted December 30, 2011 Posted December 30, 2011 Reteid, this?http://www.discobrakes.com/images/products/500x400/OBE-DA01SG.jpg
Capricorn Posted December 30, 2011 Posted December 30, 2011 or this circlip? http://cdn.mos.bikeradar.com/images/bikes-and-gear/components/disc-brake-systems/1267440552747-17mpas5qj97ad-500-90-500-70.jpg
Capricorn Posted December 30, 2011 Posted December 30, 2011 or one of these clips?http://www.chainreactioncycles.com/Images/Models/Full/26186.jpg
Capricorn Posted December 30, 2011 Posted December 30, 2011 i think it's that rectangular clip.  http://www.jejamescycles.co.uk/product-images-large/avid-juicy-5-hydraulic-disc-brake-front-40267.jpg have to scout around in my toolbox, see if I have a spare as I have had J5s before.
no calves Posted December 30, 2011 Posted December 30, 2011 go ride. its only purpose is to prevent the pads from falling out but they cant because the piston is still holding them in place
Capricorn Posted December 30, 2011 Posted December 30, 2011 (edited) go ride. its only purpose is to prevent the pads from falling out but they cant because the piston is still holding them in place  wrong wrt falling out. It's called a backing plate, and since J5s are NOT top loading, if they were to fall out, they would fall down toward the axle, not up away from it.I think that backing plate keeps the two pads aligned within the brake. Each pad has two tabs. The 'arms' on that backing plate (as depicted by the plate below teh pad spreader springs in the third image above) locks the pads in place (but wont prevent falling out) to prevent them from moving back and forth within the brake caliper. Without that plate, the pads will slide in the direction of wheel rotation under braking. While the pads will remain parallel with the brake disk because of the very fine clearances between piston and pad, and then pad and brake rotor, i'm not sure if rotate-before-brake is what a rider wants from his brakes. He will have brakes, but it will be quirksome, and something might break. Eventually, of course.btw Reteid: front or rear brakes are the problem? Edited December 30, 2011 by Capricorn
reteid Posted December 30, 2011 Author Posted December 30, 2011 front,but both front and back plate are the same.
Capricorn Posted December 30, 2011 Posted December 30, 2011 (edited) then go ride, because it's a lot easier to avoid using teh front than the rear brake,and I'd advise u use the front brakes as an emergency option only. Edited December 30, 2011 by Capricorn
