persistant_itch Posted June 11, 2013 Report Share Posted June 11, 2013 Firstly, sorry for clogging up the forum with this issue but i'm on the verge of a foooooooking meltdown! I waited 4 weeks for the seals i needed for my tech trial, I got the whole caliper seal kit for both brakes... so they arrived today and I spent the day giving the whole bike some TLC and attention, i followed hopes how to on how to bleed the tech trial and followed numerous different guides on how to rebuild the brake caliper. It turned out that the leak was from behind the bore cap so I took my sweet time, cleaned it and checked for any wear and tear, (which there appears to be none of) changed all the seals and bled the brake. .....All was well.....Rebuilt the bike....all was well, took the bike out the front just to roll around and let the brake have a test run..then the lever started to feel spongy again, and just my F*#KING LUCK, The bore cap is leaking again!!!! Stripped and rebuild again, slower this time and again just now, the same problem!!All over my brand new pads!! I've only had the bike around 3 and a bit months and i've only got to ride it properly for 1 and a half of those!! and i'm supposed to be bringing the bike to Radfest! I've barely got to practice at all! Can someone please help me here, is it new caliper time??,is there something i've done wrong?? My head is melted with this crap and i cant afford to be buying a new brake! ...Rant over (apologies) any help is much appreciated Bernard Quote Link to comment Share on other sites More sharing options...
dann2707 Posted June 11, 2013 Report Share Posted June 11, 2013 Are you sure its the bore cap? I had a massive problem with my hopes and spent far too much on the rear getting it to stop leaking. Turned out it was the piston that needed sanding ever so lightly, removed it and noticed it had dirt and grime built up which wasn't allowing it to seal properly. Worth a look maybe? good luck man Quote Link to comment Share on other sites More sharing options...

Worth a look maybe? good luck man I'm Pretty certain its the bore cap, the whole brake was dry and clean and then there was DOT fluid in a droplet at the bottom of the bore cap, but if all else fails its gonna be another strip and rebuild in the morning Quote Link to comment Share on other sites More sharing options...
cardenas_26trials Posted June 11, 2013 Report Share Posted June 11, 2013 Did you throw water on it to bed in? Quote Link to comment Share on other sites More sharing options...
kane666r Posted June 11, 2013 Report Share Posted June 11, 2013 Sounds stupid but have you checked the o ring that goes on the bore cap very rare they leak there also check you haven't cross threaded the bore cap and are you doing it up tight enough Quote Link to comment Share on other sites More sharing options...
dezmtber Posted June 11, 2013 Report Share Posted June 11, 2013 What he just said. Failing that get the brake in the post ASAP to hope tech. Give there warranty dept a call Quote Link to comment Share on other sites More sharing options...

marko Posted June 11, 2013 Report Share Posted June 11, 2013 Excuse me but did you check the 90 degree hose connector hollow bolt? I hit it once causing it to bend and deform the copper washer. They both had to be replaced to fix leakage. Tightening it more did not help. This may be mistaken for bore cap leakage. 1 Quote Link to comment Share on other sites More sharing options...

How would that help it? do you have to do that? What he just said. Failing that get the brake in the post ASAP to hope tech. Give there warranty dept a call I bought the bike 2nd hand from Andrew on the forum, and he never seemed to have any issues with them, Excuse me but did you check the 90 degree hose connector hollow bolt?

No ill look into that now thanks, but it does look fine Quote Link to comment Share on other sites More sharing options...
persistant_itch Posted June 11, 2013 Author Report Share Posted June 11, 2013 Hope just responded to an email i sent them saying that if i send it to them they can check for any faults, does that mean they'll do it for free? Quote Link to comment Share on other sites More sharing options...
persistant_itch Posted June 11, 2013 Author Report Share Posted June 11, 2013 Sorry for not adding anything useful but this fully backs up my theory of how crap Hope brakes are They seem great when working right like,when i got the bike, for the first few weeks they were like hitting a wall for power, but the amount of individual tools and parts i had to source because each caliper is slightly different really frustrated me, like i had to buy the bore tool, which is specific to that brake, if i have to buy a different brake ,the tool and any spares i have are useless to me.

BINGO i think we have a winner!! pumped the crap out of the brakes there to try and see the leak and it seems to be from there!! how much did it cost to replace? and where do you get the parts??

bing Posted June 11, 2013 Report Share Posted June 11, 2013 You should be able to get the copper washers from any car shop, or order some off crc Quote Link to comment Share on other sites More sharing options...
Revolver Posted June 11, 2013 Report Share Posted June 11, 2013 If you can afford the time, send hope the brake, and if it's a warranty job, that's fine, and if it's not, get them to send you the bits you need and fix it yourself. Quote Link to comment Share on other sites More sharing options...
