adamant Posted May 13, 2016 Report Share Posted May 13, 2016 (edited) Hi guys, pretty much iv recently bought some heat sink yellows with cnc backings, to replace my inspired pads iv got the brake working ok but not amazing, the brakes squeaks if I go back just not forwards It's on my czar mod, avid sd7 lever, standard cable, shimano arms, onza vee adaptors, echo brake booster and a grind on my rim, the brake worked great with the inspired pads but I can't get the heat sinks to do that well, any tips as to what I'm doing wrong and how to improve the braking and to get the nice honk when going forwards? cheers, kev Edited May 13, 2016 by adamant Quote Link to comment Share on other sites More sharing options...
adamant Posted May 13, 2016 Author Report Share Posted May 13, 2016 It's on the rear if that helps? Got a hydro disk up front Quote Link to comment Share on other sites More sharing options...
isitafox Posted May 13, 2016 Report Share Posted May 13, 2016 What rim and how fresh is the grind? I've found with heatsinks in the past that they're not super amazing on things like Trialtech rims and need regular grinds whereas with echo rims they seem to bed with the grind and work brilliantly. 1 Quote Link to comment Share on other sites More sharing options...

AdamR28 Posted May 13, 2016 Report Share Posted May 13, 2016 Sounds normal to me, V brakes tend to do exactly that. Quote Link to comment Share on other sites More sharing options...
AdamAllen Posted May 13, 2016 Report Share Posted May 13, 2016 Id say its down to the pads personally, I've just bought some heatsink yellows, going off good reviews, and they are shocking. performing really poor. no bite and no hold at all.

AdamR28 Posted May 13, 2016 Report Share Posted May 13, 2016 It's definitely nothing to do with the pads - turn them round 180 degrees and you'd still have the same characteristics. Quote Link to comment Share on other sites More sharing options...

Bottleneck Posted May 13, 2016 Report Share Posted May 13, 2016 If your brake squeaks when you're going backwards and not forwards, maybe the pads don't contact the rim squarely when you break, meaning they are tilted away from the rim a bit more at the top. I found exactly the same thing happening on my hydraulic rim brakes, but I guess this still applies to vee's? Anyways try and look at how your pads contact the rim, and adjust them so that when the brake is engaged they are absolutely square. I don't know how easy or hard it is on bee's though, but it's quite easy to do on hydraulic brakes. Quote Link to comment Share on other sites More sharing options...
Ali C Posted May 13, 2016 Report Share Posted May 13, 2016 As Adam said, that's just what V brakes do, they work almost in reverse to a Magura, less forwards bite but more rearwards hold and that's why I loved them.....a quiet brake that just clamps on when you need it most. 2 Quote Link to comment Share on other sites More sharing options...
Mark W Posted May 13, 2016 Report Share Posted May 13, 2016 Regarding the Heatsink pads, they've usually got a lot of bite/noise, so if they're not feeling great it'd be worth double checking that they're set up nice and square, and making sure you've got a decent grind on there. That doesn't necessarily mean super deep and coarse, just a light to medium but sharp grind would work well. Not going over the same bite of the rim repeatedly and stuff like that makes a big difference to how they turn out, and consequently how the pads perform.

Nothing at all, magura is working perfect, gave it a full service, fresh bleed.. pads are dead square! Even gave the rim a fresh sharp grind to try and solve this! 35 minutes ago, Mark W said: Regarding the Heatsink pads, they've usually got a lot of bite/noise, so if they're not feeling great it'd be worth double checking that they're set up nice and square, and making sure you've got a decent grind on there.

I've had heatsink reds and cousts before and they were amazing... Really cant work out why these yellows are poor!.. the only difference i have now to my previous set ups is a try-all rim compared to an old echo 07. Any help would be appreciated Quote Link to comment Share on other sites More sharing options...
Mark W Posted May 13, 2016 Report Share Posted May 13, 2016 Is it a single wall Try-All rim? If so, that will have an effect. Double wall rims do help your brake work better, and Echo's rim material holds a grind way better too. It could just be that rim being the issue, basically. Sometimes pads to take a little while to wear into a grind, so it might be worth just leaving it for a couple of rides without touching the brake/rim to see if they settle down and perform better.

AdamAllen Posted May 13, 2016 Report Share Posted May 13, 2016 Its the old double wall, yeah i remember echos holding a grind better but this really does seem poor, i've exhausted all options now the brake couldnt be set up better, so just gonna leave it like you say, hopefully it might just be taking some uber bedding in!

SamKidney Posted May 23, 2016 Report Share Posted May 23, 2016 That's just how vees are. Lack bite compared to a magura but the hold they offer is insane. Nice and quiet too. 1 Quote Link to comment Share on other sites More sharing options...

I've got an Avid Ultimate with a crappy booster on the rear and with the ADN pads and Echo SL rim it works a treat. Can't complain about the lack of bite and the hold is, as you said, very good. I have a Vee frame though so this might also be sth. to consider. With an adaptor on a magura frame the brake wasn't as good even though still on par with maguras.
