I eventually replaced my front brake with a spyre one. However I have since replaced the bike. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18123&page=2#post-358603 Sat, 19 Feb 2022 20:53:19 +0000 vladimpala 358603@http://citycyclingedinburgh.info/bbpress/ <p>Had been noticing a gradual decline in performance on my TRP Hy/rd - especially since I replaced the cables a couple of years back. And after a scary incident involving an on-coming car doing an overtake it was clearly time for action.<br /> Rather than replacing stuff bit by bit I went full bhuna with TRP branded stuff - new rotors, pads and compressionless cables. Took the units off the bike and did a brake bleed, but I didn't see any evidence of air in the system (though the oil in the rear was a strange murky greeny brown colour).<br /> Happy to report brake performance appears fully restored (dunno what I would have done if it wasnt). </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18123#post-271409 Fri, 05 Jan 2018 12:48:28 +0000 acsimpson 271409@http://citycyclingedinburgh.info/bbpress/ <p>Thanks, I certainly can't rule out some contamination on the rotor although the old pads are working fine on the new rotor.</p> <p>I've kept the old disc as a spare and now that it's had a good scrub I might try it again sometime.</p> <p>The sooner hydraulic drop brakes are affordable the better. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18123#post-271329 Thu, 04 Jan 2018 19:38:55 +0000 Blueth 271329@http://citycyclingedinburgh.info/bbpress/ <p>Apart from ensuring a clean disc and pad surface, there is a trick to setting up hydraulic discs to give a good initial bite. </p> <p>With the wheel out, the brake should be very carefully operated to get the pads as close together as possible consistent with allowing enough of a gap for the disc to fit in to place and turn freely. Theoretically, this should not be necessary but it does make a big difference.</p> <p>Your part-worn disc could probably have been retained for a while using this method. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18123#post-271306 Thu, 04 Jan 2018 16:21:41 +0000 Grahamn 271306@http://citycyclingedinburgh.info/bbpress/ <p>I reckon your problem sounds like it was a similar issue I had with a set of the Juin hydraulic calipers (similar idea to the TRP ones) that after 6 months the pistons started sticking and I received the below from Edgesports after I asked for a refund.<br /> Seeing how I hadn<code>t even ridden through a Scottish winter I just took them off and reverted back to BB7</code>s</p> <p>We are sorry to learn that you have an issue with one of the calipers. I can confirm that the brakes are covered by a 1 year warranty.</p> <p>In our experience, the issue that you<br /> are currently experiencing is resolved by applying some mineral brake fluid to the pistons and the actuating arm, this lubricates the moving parts and rehydrates the seals. Once the oil has been applied, operate the brakes to help the oil disperse through the moving parts. Please note that mineral oil must be used and not DOT brake fluid.</p> <p>To undertake this, it is generally best to remove the pads from the caliper to prevent any pad contamination. </p> <p>After consultation with the manufacturer, it's a regime that we are recommending to be undertaken periodically to ensure maximum performance and longevity of the brakes. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18123#post-271303 Thu, 04 Jan 2018 16:01:53 +0000 I were right about that saddle 271303@http://citycyclingedinburgh.info/bbpress/ <p>Quite a mystifying tale. It's impossible to diagnose these things over the web, but I doubt disc thickness was the issue here. The pistons should have followed the wear on the rotor easily.</p> <p>The disc could have been contaminated and that could have been transferred to the pads? </p> <p>It'll take a bit of use for the new rotor to roughen up and match the old pads. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18123#post-271279 Thu, 04 Jan 2018 13:20:53 +0000 acsimpson 271279@http://citycyclingedinburgh.info/bbpress/ <p>@Moose, Thanks for the advice. Now for an update should anyone find this topic with similar issues.</p> <p>I ended up measuring my rotors and discovered that the front rotor was worn by 0.2mm (10%). I swapped the rear rotor onto the front and performance was improved although still not as good as new. I have now purchased a shiny new rotor and braking performance has been restored (other than on snow). </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18123#post-260492 Thu, 14 Sep 2017 10:29:52 +0000 Moose 260492@http://citycyclingedinburgh.info/bbpress/ <p>acsimpson - there is a thread-drift-survivors group meeting later today at the barge. dress code - no leather.</p> <p>I have found that changing the stock pads on my hyrd's made some difference. I have also heard that the caliper's reservoir doesn't come fully topped up from the factory and that lever reach can be tightened up by brimming it with mineral oil (a relatively straight forward task).</p> <p>I don't know if you are also running the trp stock rotors. I am and am going to change these as they've also been implicated in the juddering. Something to do with the wavy design that it supposedly to create a leading edge that prevents pad glazing. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18123#post-260112 Sun, 10 Sep 2017 23:34:12 +0000 unhurt 260112@http://citycyclingedinburgh.info/bbpress/ <p>I'm not sure Edinburgh is ready for gembo in leather.
