hdmackay Posted April 30, 2009 Report Share Posted April 30, 2009 Hi,I am thinking about getting a grind on my back wheel and I was wondering if you are meant to angle grind your pads aswell to make the surface ruffer?Some of my mates do it but other people don't.

Sprog! Posted April 30, 2009 Report Share Posted April 30, 2009 I don't see why people wouldn't do it you get better hold, better bite and ofcourse a better noise. Quote Link to comment Share on other sites More sharing options...
nek0 Posted April 30, 2009 Report Share Posted April 30, 2009 With new pads I did, like Rock blue's or any pads with a shiny surface. Didn't have to wait for it to break in. Quote Link to comment Share on other sites More sharing options...
Cookyboy Posted April 30, 2009 Report Share Posted April 30, 2009 Grinding your pads is ridiculous, usually give the rim a fresh grind with fresh pads but not the pads! Quote Link to comment Share on other sites More sharing options...
N.Wood Posted April 30, 2009 Report Share Posted April 30, 2009 Never done it in my life - Once you actually ride around a bit the pads will bed in anyways. Quote Link to comment Share on other sites More sharing options...
Mike W Posted April 30, 2009 Report Share Posted April 30, 2009 Put the angle grinder down, and use rims without stupid grinds.All grinds do is make your bike look and ride worse. Quote Link to comment Share on other sites More sharing options...
0zzy Posted April 30, 2009 Report Share Posted April 30, 2009 IF YOU CALL RIDING A BIKE WITH A WORSE BRAKE BETTER THEN YER, I WOULD NEVER USE SMOOTH RIM PADS AGAIN, ALRITE BITE BUT f**k ALL HOLD WITH OUT TAR. AND THEN THE RAIN COMES...... sorry for caps lol. Quote Link to comment Share on other sites More sharing options...
Connor Powell Posted April 30, 2009 Report Share Posted April 30, 2009 Yeah, totally agree with ozzy, Smooth rim makes you bike look worse because if you have a smooth rim thats not black you get nasty smeary tar marks showing, and when the rain comes your ballsed.

Krisboats Posted May 1, 2009 Report Share Posted May 1, 2009 Using a grinder on your pads usually melts them instead of cutting them as your trying to remove as little material as you can whilst roughening up the surface. Extreme heat changes the material properties too so unless your really careful there's a chance of mucking them up entirely.I've always found grinding them so the entire surface is flat without curved edges is far more beneficial than roughening up the pad surface. In fact, i don't know when the latter has ever been helpful as the grind wears the surface flat very quickly anyway. Quote Link to comment Share on other sites More sharing options...

Tomm Posted May 1, 2009 Report Share Posted May 1, 2009 Grinds are good for rims but why on earth would you grind the pads?! You'll just lose pad material and that stuff isn't cheap! Sometimes if the pads are looking glazed or they're contaminated, then I would take the shine off with some sandpaper, but using a grinder to do it is a bad idea.

hdmackay Posted May 1, 2009 Author Report Share Posted May 1, 2009 Ok, thanks for all your guys help. I don't think I will do it then. Quote Link to comment Share on other sites More sharing options...
nek0 Posted May 1, 2009 Report Share Posted May 1, 2009 I roughen them up, yes it does slightly melt the surface but never had a problem, if anything use sandpaper.Then again if you use pads like Phat it's great straight out of the bag :$ Quote Link to comment Share on other sites More sharing options...

ThanksHunterHi, yer grindong your pads is not the best idea, the only time i would ever do anything to my pads was if, they were brand new and they had a shiny film on them, but then i would only use sandpaper or sumthing to rub it offThe ground rim would give enough resistance and also you be going through pads like theres no tomorrow.Dean.

mountian goat Posted May 2, 2009 Report Share Posted May 2, 2009 sandpaper the top shinny part off then your away Quote Link to comment Share on other sites More sharing options...
shamus Posted May 2, 2009 Report Share Posted May 2, 2009 (edited) surely roughing the surface will reduce the amount of material in contact with the rim and make the brake worse?anyway just use decent pads and a decent grind (doesn't always need to be fresh/sharp)and set up the brake PROPERLY!my brake is never playing up because i take time and set up the brake well. runnin monty pads (short) on a pretty worn grind (echo rim) with a booster and the original bleed for the maggie from 2005 Edited May 2, 2009 by shamus Quote Link to comment Share on other sites More sharing options...
16 years later Posted May 2, 2009 Report Share Posted May 2, 2009 surely roughing the surface will reduce the amount of material in contact with the rim and make the brake worse?No, it will increase the amount of pad to rim contact, because the pad and rim will interface more AKA the pad pushes into the surface of the rime more and increase the amount of contact.Make sense?Any way, I’ve never ground a pad; don’t think I ever will either. I sometimes sand the shiny surface off though. Quote Link to comment Share on other sites More sharing options...
