ogre Posted September 15, 2017 Report Share Posted September 15, 2017 service them, get new seals and lubricate those badboys check the piston (i think thats what it's called; bit that actually moves the pad) for any damage or burs. Quote Link to comment Share on other sites More sharing options...

onza wanabe Posted September 16, 2017 Author Report Share Posted September 16, 2017 I have surfed the web and found nothing to help me with hope trial zone caliper servicing can someone possibly link me something please Quote Link to comment Share on other sites More sharing options...
ogre Posted September 16, 2017 Report Share Posted September 16, 2017 any hope servicing guide will work, the only difference between the trials and xc brakes is the size of the pistons to acheive different ratios, so long as you find a guide with a similar lever you should be able to work everything else out easily enough. just make sure you order the right consumable parts so you can re-build it.

ogre Posted September 16, 2017 Report Share Posted September 16, 2017 https://steveukmtb.wordpress.com/hope-caliper-overhaul-minitrialsm4v2m6/ they're all the same brakes inside. only differences are aesthetic and some degree of extra tech on the lever blades...
