bodger Posted October 21, 2021 Report Share Posted October 21, 2021 Hi all RH or LH no stamp on disc thanks Link to comment Share on other sites More sharing options...
dougbgt6 Posted October 21, 2021 Report Share Posted October 21, 2021 You have to imagine the disc rotating, one way throws the brake pad dust outwards to the road, the other way inwards towards the bearings, you want outwards. I had them for a short while, took 'em off! Nobody tells you how noisy they are! Doug Link to comment Share on other sites More sharing options...
DVD3500 Posted October 21, 2021 Report Share Posted October 21, 2021 Personally I think decent brakes and pads and a properly bled system is fine for normal to hard road use. Downshifting also helps a might too... I see on BookFace every week people who have a car that is literally falling apart and they are worried about the stopping power of a car that can't even move!

Clive Posted October 21, 2021 Report Share Posted October 21, 2021 Now now, OP just asked a civilised question. Not opinions. In fact I can't decide what way round I would use them. But (probably) the one shown is LH? In use I doubt it will make any difference. 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 21, 2021 Report Share Posted October 21, 2021 sorry just these add on parts often give you a problem or headache you didnt know about till its committed i would take a guess that the angle of the radial slots makes the pictured one the N/S but slots with closed ends puzzle me the basic idea is to clear dust and let gasses escape with the pad covering the slot i think all you may get is noise and early pad wear yes there are drillings to supposedly release gas if there is any ??

And worryingly some people (not you) offer opinions which are based on other peoples opinions found elsewhere, and the cycle just goes round and round. A simple question needs a simple answer. Not the "you bought the wrong thing" So here is my opinion. The key is quality brake pads. Yes, I believe drilled/grooved discs are all about gas release on racing pads??

JohnD Posted October 21, 2021 Report Share Posted October 21, 2021 Slots are complete borrocks. They are sold as acting through their sharp edges to "keep the pads clean" rather than expel dust, which is snake oil of the most reptile. Drillings are complete borrocks. They are supposed to "allow the gases to expand and keep the pads on the disc" There should be no "gases" coming off your pads if you bedded them in correctly, and any way, both ends of the drilling wlll be blocked by the opposing pads, so the only volume to expand into is IN the disc, about 0.25mls! There might be some air, heated and expanded by braking, but that's minimal, and unimportant for road driving The benefits, if any, are tiny. Some race teams, seeking incremental gain will use them, but they will change them after every race, because the tendency for cracks to develop between the holes makes them very short lived.

dougbgt6 Posted October 21, 2021 Report Share Posted October 21, 2021 (edited) Guys, The bloke asked a question, I gave an answer and an opinion. This was followed by 7 other opinions, but no answers to the question, not until Pete's last comment. This is sort of thing that put me off Club Triumph and will certainly put newbies off this forum. Doug Sorry Clive gave an answer as well. Edited October 21, 2021 by dougbgt6 missed Clive! 2 Link to comment Share on other sites More sharing options...
Clive Posted October 21, 2021 Report Share Posted October 21, 2021 Put yourself in the OP's shoes. You post what seems a fair question. But the vast majority of replies are telling him he is wrong, bought the wrong parts, all rather disheartening. I wouldn't blame him for thinking he would be better off elsewhere. Yes, I think we have got into the habit of letting threads move away from the question asked, but that is probably a reflection on us being keen to share our knowledge (or some people their ignorance, there are a few). But it is not always helpful. 2 Link to comment Share on other sites More sharing options...

I worked it out by imagining the disc rotating and water or whatever being thrown outward - good old centrifugal force. Bodger : It is you car do as you wish, this has been said many times on the forum.

But the vast majority of replies are telling him he is wrong That's a question of perspective. Sure, if you're a snowflake that's been brought up to believe you can never be wrong and anyone correcting you is being offensive and insulting, then that's how you'd read it. And yes, you'd probably walk away feeling offended. Nobody knows everything. If somebody with more experience tells me something I didn't know, whether I asked about it or not, then I'd hope I would accept it as an opportunity to learn and/or a warning that my current course of action may be less optimal than I thought. Doug's reply was, to my mind, perfect. Link to comment Share on other sites More sharing options...

I had thought you, particularly, could see more, than using this ,"generally right wing terminology", I think?, in the standard way, that maybe isn't healthy for us all. Hope I wasn't correcting too much, as I probably do, fall into the "general" snowflake category, I imagine🙂 Edited October 21, 2021 by daverclasper Link to comment Share on other sites More sharing options...
NonMember Posted October 21, 2021 Report Share Posted October 21, 2021 Sorry, "snowflake" was an unfortunate term and I shouldn't have used it. I do think Clive is being overly defensive on behalf of the OP, though. Link to comment Share on other sites More sharing options...

postman Posted October 21, 2021 Report Share Posted October 21, 2021 Yes, it's a left hand side disc... ...and no, grooves and slots are far from being a waste of time, especially in wet conditions. In fact, the pressed steel rain guard becomes superfluous as the drilled disc is far superior in the wet. ...and no, they should not need regular replacement. In fact, I've never had to replace one due to cracking or any kind of failure. All in my opinion and personal experience of course. Link to comment Share on other sites More sharing options...
postman Posted October 21, 2021 Report Share Posted October 21, 2021 ...oh, and the only discs I have ever known to be 'replaced after every race' are the sacrificial carbon ones used in the very highest levels of motorsport. Link to comment Share on other sites More sharing options...
PeteH Posted October 22, 2021 Report Share Posted October 22, 2021 A lot of Modern, and not so modern, Motorcycles with drilled disc`s?. My 1984 "Beemer" for one. One cannot see manufacturers spending extra time and money on machining with no benefit?. The Bean Counters, would veto it!. Pete Link to comment Share on other sites More sharing options...
