ScotchDave Posted April 4, 2005 Report Share Posted April 4, 2005 Hmm, I've used 2 sets of blues, one v and one maggie on a ceramic rim for a long time and I am big and heavy and have never had any trouble like that. :lol: Tis a shane because they give a mint brake.

TomN Posted April 4, 2005 Report Share Posted April 4, 2005 I had Heatsink Batch B and C's and both pads one of each have come off backing but bit of super glue sorts it out. Quote Link to comment Share on other sites More sharing options...
Watson© Posted April 4, 2005 Report Share Posted April 4, 2005 Will, why get Koxx browns when you could get the greens? :) I had a quick ride in the wet then just to see if my new Try-All tyre up front was any good (It is. Oh yes, it is.), but then I noticed how uber good my back brake is. Proper lock, bite and hold now. It's all freaking good. It sucks that it's about | | thin when you get it, but hopefully it'll last a while :lol: Anyway, I'd definitely recommend them. If the wear rate's wank I'll put a post in Pad Review, but yeah, they're well worth looking at :S ← Are you taking about the RimJam Greens?? If you are then I will agree with you 100%... they work f**king amazing in the wet, lock like a bitch. I was very surprised as I though they wouldnt hold but I was proven wrong :S The wear rate is a bit of a let down though as I have a heavy grind and there going down pretty fast :P ( Read what I wrote in my previous post about what Chris is doing to sort the wear rate problem :P ) Watson Quote Link to comment Share on other sites More sharing options...

Speaking of pads - my Plaz CRM worked freakishly well in the wet yesterday on my new Try-All front rim, without a grind. Weirded me out, that's for sure.

wally Posted April 4, 2005 Report Share Posted April 4, 2005 (edited) spunkey_monkey_boy's pad were some of the very first ones, on the old backings too, at that time we were experimenting with different glues. We also had some trouble with the glue sticking to the pure white plastic. But we do not use the pure white plastic anymore, or that glue. An update is, we are working on a deeper recess and more glues which will help cure this problem. We are also working on a new shape and wider pad, which will help wear rate. I will be sending out pads to people like Ross to try soon. :lol: Hope this helps, and i will keep you posted on updates. :S Thanks, Chris Edited April 4, 2005 by wally Quote Link to comment Share on other sites More sharing options...

Weirded me out, that's for sure. ← I had CRM's on the front with no grind and they were poo :lol: Then decided to put a lightish grind on an shit me, they lock up soo nice. Only downside is that they squeal like a b*****d so I have to jump off the bike to slow myself down. I don't think i'll be using any other pads. I think i'm going to stick with Koxx and CRM's Quote Link to comment Share on other sites More sharing options...
PythonRider Posted April 4, 2005 Report Share Posted April 4, 2005 People saying about heatsinks being amazing.... Mine are absoultly W*nk! Ive had the batch B yellow pads, and now the 2005 Gens and they do not work at all....No hold and only a bit of bite,(Both pairs) which is nothing compared to my blue rimjams which were mint, but wore down so fast, and at a dodgy angle becuase they pivoted so much on the piston. Pauly has some greem rimjams and oh my god! they feel soo nich, bite and seem to have a nice hold on them too! My input :lol: Tom Quote Link to comment Share on other sites More sharing options...

There is quite a few things that can contribute to a working brake. Pad choice if only one of them. Other things to consider are: Actual brake set-up Is it bled properly Flex in the frame (using a booster ?) Rim choice, as a koxx/viz rim will work SHIT with a pad that will work well on an echo/onza ronnie/alex rim. Is the grind done properly? Depending on grinding discs and techniques you can make a right 'henry halls' of it then blame the pads. Heatinks/Koxx bloxx get shit reviews from a lot of people who use koxx/viz rims. This is because as originally stated these pads are quite hard and really do need a rim with harder material. Quote Link to comment Share on other sites More sharing options...

Brisa Posted April 4, 2005 Report Share Posted April 4, 2005 Well I meant he tried making some for the softer rim types, Just as koxx have too with all the new pads. What ever happened to the tarty pads, they looked really promising. Always wanted to give a set a go. Quote Link to comment Share on other sites More sharing options...

As for the Tarty ones - haven't got time to make any :lol: Hoping to look into better production methods, like Steve... we're about half way there at a guess...

Brisa Posted April 4, 2005 Report Share Posted April 4, 2005 So thats how they came across it? :lol: I read on one Onzaboymarks posts that there was very little material. Are all of the new koxx pads like this? Or just certain colours? sorry :S Will give the Tarty pads a try when they show up, looking forward to that.

Tartridge Posted April 4, 2005 Report Share Posted April 4, 2005 im sure the new koxx ones are softer and not justa diffenent colour :ermm: ← Please remember that softness and wear resistance are two totally seperate things... You can have a soft pad, that takes ages to wear... or a hard pad, that wears fast. It is the compound that dictates how grippy/wear resistant a brake pad is. Grip and wear resistance are generally a trade-off. Quote Link to comment Share on other sites More sharing options...
Heatsink Posted April 4, 2005 Report Share Posted April 4, 2005 Not wanting to be controversal, but I'd disagree about the pigmentation of the pads affecting pad performance for a given compound. The reason why the colour has no effect on the physical properties of the compound is that the pigmentation % additive level during preparation of the material is very very small. Any perceived differences in performance can be explained by 2 things: 1. Material performance/softness tolerances from manufacture which can be substantial depending on the sophistication of the material processing equipment. By nature, two different coloured samples will have been prepared in seperate batches and so be susceptable to these material tolerances. 2. The subjective and variable nature of other parameters comprising the braking system. Talking in general about brake pad testing, to get an accurate comparision (by making all aspects equal such as brake set-up, surface condition, grease level etc) which you can put figures on, testing off the bike is required on a "rig" which rules out the variable parameters in the braking system, and so makes everything equal so only the pad performance is under scrutiny. In this way, two important things to quantify are: 1. Coefficient of friction 2. Wear rate From this it's possible to say such things as pad 1 is X times more grippy than pad 2, and that pad 3 wears Y times quicker than pad 4 for the given abrasive medium. I've got some very interesting results from my own testing across many samples of each of the commercially available pads. Of course, the bench mark for high calibre performance needs to be set on the bike itself, but then by taking the testing off the bike, you can see that that's where you find out some really interesting things and get to the truth of the matter! As a general rule softer pads have a higher coefficient of friction, but for a manually operated braking systems, too soft is bad news because of: 1. Soft brake feel 2. Difficulty to retain pad on backing due to the peel rather than shear mechanism under braking 3. Distortion under braking causes exaggerated rounding of the corners and such. This localised wearing can prematurely shorten the life of your pads! On the brake pads falling apart thing, check out what happened when I took a brand new and unused pair of Coust pads and put them onto a loose slave cylinder and then tried to remove them: Sorry to all of those sick to the back teeth with topics about pads for bumping this back to the top of the board! :"> Steve Quote Link to comment Share on other sites More sharing options...

wally Posted April 4, 2005 Report Share Posted April 4, 2005 Steve did you buy those coust pads? :ermm: Thats how i started off doin my backings, with an o ring, but i never sold those ones, i couldn't quite get it right. Quote Link to comment Share on other sites More sharing options...

Can't say i've ever looked into that :ermm: Have you tested differing compounds of the same hardness? I found compound to make a great difference in performance once a satisfactory hardness had been found. Quote Link to comment Share on other sites More sharing options...

Steve did you buy those coust pads? ← I bought them because I wanted to see whether the hype was merited.
