RussDix Posted August 12, 2014 Share Hi guys, I put new brake pads on my bike today and now they hardly working. Only once the lever basically touches the bars do you feel anything start to happen. I bled them and still no improvement, any advice on how I can sort this out?They are avid juicey disk brakes.Thanks Link to comment Share on other sites More sharing options...

Mojoman Posted August 12, 2014 Share Did you sand the pads and disc a little bit first? Link to comment Share on other sites More sharing options...
Capricorn Posted August 12, 2014 Share are your pads and rotor clean, as in free of oil/grease? Link to comment Share on other sites More sharing options...
akneethling Posted August 12, 2014 Share Did you bed in the pads? This will clean the surfaces of any glazing and build up as well. Robodog 1 Link to comment Share on other sites More sharing options...
Vangar Posted August 12, 2014 Share Seems they are breaking perfectly. But braking not so much. Stretch, Catatonic_Joe, BarHugger and 6 others 9 Link to comment Share on other sites More sharing options...

Captain Fastbastard Mayhem Posted August 12, 2014 Share Remove with hammer.Install Shimano XT's Have a beer. Bull. Crap. Either a bleed (which Shimanos don't like) or a case of contaminated pads (which affect shimano equally as much) or you didn't bed them in properly (which would - FANCY THAT!!! - Also affect shimano) Starvin' Marvin and BogusOne 2 Link to comment Share on other sites More sharing options...
TrackGuy Posted August 12, 2014 Share Before you bleed the brake, you could also try to burp them. Google it. And you could also try and flip the bike over and press the brake a few times and flip back over on the wheel again and press the brake again. There might just be a little air bubble in there when you pushed back the pistons. Just try and first get rid of it that way, I did this and it worked for me, no need for a bleed.

RussDix Posted August 13, 2014 Share Thanks for the response everyone. I will fiddle around with them today maybe go for a bit of a ride and see if that helps at all. It just seems as if when I pull the brake hard there is hardly any pressure or resistance against the disc. Link to comment Share on other sites More sharing options...
JXV Posted August 13, 2014 Share Are the old pads worn exactly parallel to the backing plate? If not this is a sign the calipers and new pads are not aligned to the disc. If the brakes were working well before changing pads this could be the reason. Juicys have those cone washers on the mounting that allow you to get the pads exactly parallel to the disc. Do this alignment first. Then if the brake levers still fell spongy air is the likely cause and bleeding is needed. It wont hurt to clean and gently sand the new pads by rubbing against fine sandpaper backed by a flat surface such as wooden block. Link to comment Share on other sites More sharing options...
JXV Posted August 13, 2014 Share PS also make sure u did not spill brake fluid on the new pads while bleeding the brakes Edited August 13, 2014 by JXV Capricorn 1 Link to comment Share on other sites More sharing options...

Captain Fastbastard Mayhem Posted August 13, 2014 Share Avid owner ^^ And? I've also had shimano (my wife has them on her bike) as well as tektro. Now THOSE were crap. In the avid stable - elixir 5, xx + code. The OP's problem could occur with any brand. Maybe a bit of diet stuck next to the piston, but most probably air in the system and improperly bedded pads Robodog and BogusOne 2 Link to comment Share on other sites More sharing options...
