ogre Posted January 25, 2006 Report Share Posted January 25, 2006 people went for the Pressure thing (less area more pressure) but its bollox, more pad = betterAmen to that. http://www.timesdispatch.com/servlet/Satel...d=1137833607005 bit off topis but hahahaha all the same =) Quote Link to comment Share on other sites More sharing options...
JT! Posted January 25, 2006 Report Share Posted January 25, 2006 (edited) The forse applied onto the rim with 50mm and 35 mm pads will be the same, if this wasn't true - and 35mm pads were crap becuase they're smaller, where does the forse from the slaves go on the 35mm pads?

Hobnobs Posted January 25, 2006 Report Share Posted January 25, 2006 Yeah, but its on a smaller area. Meaning its pushing harder at that point. How about we forget physics and ride them, yeh, sounds good to me. Quote Link to comment Share on other sites More sharing options...
Mark W Posted January 25, 2006 Report Share Posted January 25, 2006 Loved all the 35mm pads I've tried, but 7.5mm each end of a pad means f**k all to me, to be honest. Don't think you're suddenly going to think "Hmm, there's _ _% less material hittin the rim than there could be" or anything like that. If the compound's good, and they don't shed their backings, it doesn't matter how wide they are - 50 or 35. Quote Link to comment Share on other sites More sharing options...

How about we forget physics and ride them, yeh, sounds good to me. It's against the laws of physics for the brake to increase performance buy reducing the sise of the pad.

Mark W Posted January 25, 2006 Report Share Posted January 25, 2006 How's that then? Pressure = force/area. Less area with the same force = more pressure, = more stoppy stop Either way, it's neither here nor there. It seems the main reason it was introduced was to make it a little easier to set Maguras up with the sometimes shallow braking surfaces on a lot of trials rims.

wayneone Posted January 25, 2006 Report Share Posted January 25, 2006 Isnt it the same concept with walking on the snow? if you have say high heels on your gonna sink quick but if you have them massive snow shoes that are realy wide you wont sink as much.

Heatsink Posted January 26, 2006 Report Share Posted January 26, 2006 For me what strikes me about the 35mm backings is the ease of preparing the pads and then assembling them. For this reason along they are very appealing! It still takes me a fair while when I need to hand cut pads to fit the 50mm backings, but the 35mm ones require just a flat surface and some decent glueing. You can get really decent adhesion even though there's no recessed form, but you mustn't go beyond a certain softness with the pads because you need sufficient stiffness in the pad itself to stop the braking action being turned into a peeling mechanism rather than a shearing one. This shouldn't be an issue though because the Monty pads and also Koxx and Coust have shown that you can get the grip performance you're looking for in a sufficiently stiff pad that can be retained well on the flat backings.The more pad choice the better in my opinion!Steve Quote Link to comment Share on other sites More sharing options...

It seems the main reason it was introduced was to make it a little easier to set Maguras up with the sometimes shallow braking surfaces on a lot of trials rims.Righty ho...What you said there was right. The force on the rim is increased when you use smaller pads. But when you reduce the sise of the pad, the surface area is being reduced.On bigger pads, the force is less because it has a bigger surface area. But the surface area has been increase because there's more pad touching the rim.. More surface area means more friction. More force (the force against the rim) means more friction.When you increase one the other one decease, and visa versa.So that means that no matter what sise the pads are, they will always have the same friction.The force from the maguras piston is constant so that can be completely ignored, when I refer to 'force' above I’m referring to the force felt by the rim which vary with surface area.That's why 35mm have the same braking power.However, they will wear down quicker. 30% quicker in theory. But they're cheaper, because there are less of them. And they are easier to set up as said above.But, they're more prone to the rubber ripping off their backings (not saying they will but are more likely) because the base of the rubber is less, but the height is the same. (Again like said above)So to sum up really, it doesn’t matter. Edited January 26, 2006 by JT! Quote Link to comment Share on other sites More sharing options...

If what you said was contredicting yourself, then yeah.The reason i posted it up really was just metaphoric 'full-stop' to my 3 hours thinking about how pad length effect braking power.

Mark W Posted January 26, 2006 Report Share Posted January 26, 2006 Yeah, I knew about how it would work out pretty even, was just making a point as to what would potentially be the "pro" side of using 35mm pads, 'cos I cba going into it all, unlike your good self, evidently Quote Link to comment Share on other sites More sharing options...
JIX Posted January 26, 2006 Report Share Posted January 26, 2006 Friction is not effected by the size of the area in contact. So these pads no matter what size will have the same value of friction. Quote Link to comment Share on other sites More sharing options...
Janson Posted January 26, 2006 Report Share Posted January 26, 2006 Ffr = µ*K.Where Ffr is the friction force, µ is the friction coefficient, and K the applied force via the brake.No areas...It's harder to set the brake up properly with short pads.Force is not reduced when the area is increased, the PRESSURE is reduced...

Dan6061 Posted April 22, 2006 Report Share Posted April 22, 2006 Jesus christ you guys like to argue! Back on topic. I use them on the front.Had them over a month.Got them from Tarty'Lock really well, but still have modulation.Sqeal like hell! Nice and high pitched. Done.
