liam n Posted July 28, 2011 Report Share Posted July 28, 2011 (edited) right, i need you knowledge, i'm rather shit at setting up pads square, i can't seem to do it and i don't really know what to do but i may have nailed it this time... first thing is i have Echo TR mounts and i have filed the mounts on frame, so i can't see any way of making pads any squarererer now i just got heatsink yellow refills, and put em in in the heatsink backings properly using a proper vice so the pads are square to the backings, and i set em up with the TR mounts and so on they looked square to me, and the pads are amazing great hold and good bite, but now they've started to wear they're wearing in a sort of "V" or "U" shape (however they still have great hold and good bite.... :/ now is this the wear normal? or am i ruining another set of refills? pics will be up in a minute Edited July 28, 2011 by liam n Quote Link to comment Share on other sites More sharing options...
Kieran Morrison Posted July 28, 2011 Report Share Posted July 28, 2011 This used to happen to me all the time with the same pads aswell. When i got a new brake (because my pistons were acting up - Might be why this happens in some way?) it stopped. Are the pads still as good as they were?

JD™ Posted July 28, 2011 Report Share Posted July 28, 2011 Your brake bites and holds well. What's the problem?! If there was one thing I could change about trials, it wouldn't be the tgs/street thing, it'd be people whinging about brakes. Quote Link to comment Share on other sites More sharing options...

liam n Posted July 28, 2011 Author Report Share Posted July 28, 2011 Fair point meant whats the problem then did you not read the first post, the problem is they're wearing at a funny shape and i don't want to ruin more refills ? Quote Link to comment Share on other sites More sharing options...
Kieran Morrison Posted July 28, 2011 Report Share Posted July 28, 2011 (edited) did you not read the first post, the problem is they're wearing at a funny shape and i don't want to ruin more refills ? I read most of it, if the preformance is the same then they will be fine, when my heatsinks did that they wore down really quick and then they basically stopped with half or more of the pads left, so you wont ruin them, they will last a fair bit probably with the same preformance Edit: Do you have a buckle?

Edit: Do you have a buckle? no What modification did you make to the mounts to make them square? Echo TR mounts are CNCed so they fit perfectly square on the frame mounts (and they don't use washers) and there for in theory keep the pad square against the rim... filing the the mounts on the frame make all the mount blocks square and level in comparison with each other both of the above added together in theory should have the pads/brake perfectly square against the rim sidewall Quote Link to comment Share on other sites More sharing options...

Kieran Morrison Posted July 28, 2011 Report Share Posted July 28, 2011 I meant they wore down really quick until a cetain point(well to be honest it wasnt very quick) and then they just stopped wearing. Quote Link to comment Share on other sites More sharing options...

In my opinion, no they're shit, but that's probably my feeble mind, and i find normal maggy mounts 1000 times more annoying Quote Link to comment Share on other sites More sharing options...

Saves so much time setting up brakes aswell Quote Link to comment Share on other sites More sharing options...

Martin Reynolds Posted July 28, 2011 Report Share Posted July 28, 2011 The thing you got to remember liam is that the pads are set up square with no load. As soon as you press the lever, the frame will flex, causing the pads to wear uneven. Also, if one part of the pad grips the rim, this can cause the pad to roll, causing uneven wear. It doesnt look that uneven, just keep an eye on it Quote Link to comment Share on other sites More sharing options...

Martin Reynolds Posted July 28, 2011 Report Share Posted July 28, 2011 Considering ur talking on here and not on msn/fb, you got any spare pads? even with little material? Cant get a decent front brake on my blade :/ Quote Link to comment Share on other sites More sharing options...
forteh Posted July 29, 2011 Report Share Posted July 29, 2011 When setting up new maggie pads, Ive always initially set them up as square as I can and then just left them to wear in, I never worry if theyre wearing at a slight angle as long as they are working. The pad will wear to the shape of the rim, be that angled, perfectly square, on the piss or whatever; it doesnt really matter what position the backing is in relation as long as the pad material is wearing square to the rim surface. I have noticed (as with keiron) is that heatsink yellows seem to have an initial break in period where the pad seems to wear out super quick, something like 2mm in a several hours riding. After that they stop wearing, mine are now almost two years old and still got 4-5mm material left and going strong. The important thing to remember is to not mess around with the brake setup, each time you move the pads/cylinders will need to bed the pads into the rim again.

Greetings Posted July 29, 2011 Report Share Posted July 29, 2011 (edited) first thing is i have Echo TR mounts and i have filed the mounts on frame, so i can't see any way of making pads any squarererer That's worth pointing out for others, it's an often overlooked aspect of setting brakes up and can work wonders. The main reason why pads round off is because they move about in the caliper. To put it short, depending on which direction you're braking, half the pad is doing it's job, whereas the other half isn't producing much braking power. Because of this twist, the pads don't wear down square. There's a number of factors which cause the pads to move around but the main one is that the contact area between the piston and backing is very small. Another can be the tolerances between the pad guides on the caliper and the backings although tight tolerances just cause the brake to be less responsive under load. If you're having excessive problems with uneven wear I'd check the backings, the piston for play and the overall condition of the piston.
